Geyser Bosch wr 10 2p can work both from natural and from liquefied gas, i.e. balloon. It is equipped with triple protection: a thermoelement for controlling the ignition flame, controlling the draft of gas combustion products, and a temperature limiter that protects the column from overheating.
The model is also equipped with a reliable flame modulation system. This means that the column automatically adjusts the heating to the required fluid flow. If you are washing dishes in the kitchen, and someone decides to wash in the shower, the water temperature will be the same, both in the kitchen and in the shower. The power of the liquid at the outlet is also automatically regulated when the water pressure in the water supply changes.
Before turning on, according to the operating instructions for the Bosch geyser, you need to make sure that there is draft in the chimney. this can be done by bringing a lit candle or match to the chimney. If the flame deviates towards the chimney, then everything is in order with the draft, and the device can be turned on.
If there is no draft, you should find out the cause and clean the air duct, or seal the seams of the air duct pipes if a loose fit of its parts is found. When the column is operating, make sure that the window or window is ajar, the door in the room where the column is installed should not close tightly.
This ensures the natural movement of air and the flow of oxygen, the unit burns during operation a large number of oxygen. Failure to comply with these requirements may result in poisoning. carbon monoxide. It should also be remembered that when the column is running, you cannot turn on the fan or air conditioner, this disrupts the outflow carbon monoxide through the chimney.
On the front panel of the apparatus on the left there is a slider that regulates the power, on the right there is a toggle switch for the volume of liquid, above them there is a viewing window. Never get too close to it to avoid burns.
If starting for the first time or after long downtime, some air may accumulate in the dispenser pipes. To remove it, open and close the tap several times with hot water, at intervals of about a minute, until it is completely removed.
When first turned on, open the gas and water supply valves, open the faucet hot water to make sure fluid is coming in.
The Bosch column has a piezo ignition system, the button of which is located at the bottom left. To turn it on, you need to move the slider from the left extreme position to the ignition position, indicated by an asterisk. Drown it and at the same time press the piezo ignition button several times until the ignition flame appears.
At the same time, loud clicks are heard, they should not be scared, as it should be. If the pilot flame ignites, release the slider button, if ignition does not occur, repeat the entire procedure again. The unit may not start if, after a long period of inactivity or when first turned on in gas pipes air got in. To remove it, hold the slider button in a recessed state until all air is removed.
Once the unit has turned on, set the power you need using the same slider. The extreme right position provides maximum power, while increasing gas consumption. By using round pen the required fluid flow and its temperature are set.
By turning the knob clockwise, you reduce the flow and increase the temperature, by turning it counterclockwise, on the contrary, the flow increases, the temperature decreases. Installation high temperature increases gas consumption and scale formation in the heat exchanger.
The pilot flame burns constantly, and the main burner ignites at the moment the hot water tap is opened. The shutdown occurs when you turn off the hot water tap. To turn off the unit completely, move the power regulator slider to the extreme left position, the pilot flame will go out ...
If there is a risk of water freezing in the appliance, e.g. in a country house in winter period must be completely drained of water. To do this, close the water and gas supply valves, open the taps on the mixer.
Remove the housing cover by unscrewing a few bolts to access the water unit. Remove the bracket in the form of the letter “P” from the filter housing on the water fitting and remove the plug, which is located immediately behind the bracket. Wait a while until the liquid is completely drained.
To prolong the life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean the inside of the column from dust and soot, rinse the heat exchanger from scale. At the same time, you should be aware that all work with gas equipment should be carried out only by a specialist.
After all preparations have been made Bosch boiler Gaz 6000 for launch, after pre-launch preparation, which includes checking expansion tank, stop valves, filters, checking the pressure in the gas line, the tightness of the connection of all joints, the boiler is connected to the electrical network.
After powering up to the mains, the “attention” icon appears on the electronic display, which is located on the front panel of the unit. Next, press the power button on the front panel, located near the upper left corner of the electronic display. Above the display is a magnetic instruction that allows you to easily change the settings of the unit.
When turned on, within two seconds, the boiler electronics conducts self-diagnostics, all sensors are checked and switched to blocking mode. The display shows the current temperature and status code. Next, it is necessary to adapt the fan speed to the length of the chimney to which the unit is connected.
This operation is performed by simultaneously pressing and holding three buttons - "+", "-" and "back". The mode is set in accordance with the parameter specified in the instructions for the device - we set the second service level, confirm the action with the "ok" button, holding it until square brackets appear on the display.
In addition to the display, in the lower right part, a pressure gauge is mounted showing the pressure in the system, the normal pressure is in the green zone. The red zone indicates the pressure below and above the nominal pressure when the protection is activated and the unit is turned off.
Bosch THERM 4000
You can increase the pressure using the blue tap by unscrewing it counterclockwise until the pressure gauge needle returns to the blue zone. When the pressure increases, the liquid will be discharged through the corrugated tube at the bottom of the unit and the pressure gauge will return to its normal position.
The boiler can operate in two modes, liquid heating and heating mode, which of the modes is active, shows the icon on the display.
The mode is selected by pressing the "+" or "mode" button. After selecting the mode, set desired temperature, then press "ok" - confirm the choice, after which the up and down arrows appear on the display, use the "+" and "-" buttons to set desired temperature heating. To save the selection, press the OK button and hold for a couple of seconds.
If it is necessary to set the heating operating mode, select it with the “-” button, confirm by pressing “OK”. The choice of temperature and saving the choice is carried out in the same way as when setting the water heating temperature. The fire icon that appears on the display indicates that the turbine has turned on and heating has begun.
When the set temperature is reached, the fire icon will disappear, after falling, when the boiler turns on again, it will appear again, this will happen cyclically throughout the entire operation of the boiler when given parameters. In the event of any malfunctions in the operation of the Bosch Gaz 6000, for example, in the absence of gas or water supply, the protection will work and an error message will appear on the display.
The interpretation of the error and the actions to eliminate it are described in the instructions for the boiler. After identifying and eliminating the cause, you must confirm the action on the display by pressing and holding the "ok" button for a few seconds. After that, the boiler automatically starts up again.
The unit is protected from freezing if the pump is running and fluid is circulating through heating system. If the boiler needs to be turned off, then antifreeze is added to the heating liquid, and water is drained from the hot water supply, as a rule, this work is done by a specialist. Maintenance is also carried out by a specialist, since the unit is quite complex device associated with high blood pressure and gas.
We offer you to watch a video about the rules for setting up the Bosch 4000 O column:
The company "Real autogas" provides users with operating instructions for gas equipment Tamona (Baltic region)

Remote Control
The control panel is designed to work in the TGstream system. On the front
part of the control panel there are 7 LEDs (yellow, red and 5
green) and 2 control buttons. The rear panel has a socket for
connection of the main unit.
Control buttons
Petrol. Sets the TGstream system to Gasoline mode.
Gas. Switches the TGstream system to the "Automatic" mode, followed by
automatic switching to gas.
Light indication
5 green LEDs and a red one serve as indicators of the gas level in the cylinder (red - the minimum level) and the "Automatic" and "Gas" operating modes, and the yellow one - the "Petrol" mode.
Sound indication
The built-in buzzer warns the driver with two short beeps about the minimum
gas level in the cylinder (red LED on) and an intermittent signal about
emergency transition to petrol (yellow LED on) in the absence of gas. You can interrupt the buzzer signal by switching the TGstream system operation mode by pressing the button on the control panel.
Note!
If, when the gas cylinder is full, the red LED turns on and the buzzer sounds twice, then either the gas level sensor in the cylinder is not connected, or the sensor configuration is incorrectly set in the TamonaGAS program on the “Configuration (F2) - Devices (F12)” tab, point 1. You must contact to a car service to configure or disable the gas level sensor in the configuration if it is not physically connected.
TGstream operating modes
You can switch operating modes at any time during the operation of the vehicle.
"Machine"
The car starts and runs on petrol (yellow LED on and blinking green LED located in the left corner of the control panel). After all the conditions for switching to gas (temperature of the gas reducer, pressure, engine speed), the parameters of which are set in the car service at the time of setting up the car, are met, the transition to gas occurs (all green LEDs are on and the yellow one is off). In the event of a minimum gas level in the cylinder at the time of switching to gas, the driver is warned about this by two short beeps.
The car runs on gas (only after automatic switching from the "Automatic" mode or using forced winding on gas, described below). A full indication of the gas level in the cylinder is carried out. If, during the operation of the car in this mode, the gas level in the cylinder drops below the minimum, the driver will be warned about this by two short beeps (see note), and in the event of an emergency transition to gasoline (gas is over) by a constantly intermittent signal, which can be turn it off by pressing any button on the remote control.
"Petrol"
The car starts and runs on petrol (yellow LED on).
Forced winding on gas
The possibility of forced winding on gas allows you to switch the car to gas,
bypassing the conditions listed in the description of the "Automatic" mode. Required when
ignition off, press the "G" button and, without releasing, turn on the ignition, but
do not start the car. A constant single tone buzzer sounds and all
green LEDs indicating the entry into the forced winding mode on
gas. By releasing the "G" button, you can start the car.
Everyday use
For the first time after turning on the ignition, turn on the “Automatic” mode. TGstream system
will remember this mode and will automatically switch to gas. (see mode description
"Machine"). No further management is required. No need to click on
remote control buttons. It is enough to start the car and move. The TGstream system itself
will switch over to gas. About the need to refuel soon the system
will notify you with a sound signal (if there is a gas level sensor in the cylinder, see description
gas mode).
Reading the gas level in the cylinder using the SOFTWARE software sensor
"SOFTWARE" sensor programmatically determines how much gas is consumed during
operating time and shows how much is left in the cylinder.
The benefits of using this sensor include:
No additional fuel level sensor needed;
Stable readings of the remaining gas;
The readings are correct and do not depend on the position of the vehicle (vehicle
moving uphill or downhill, leaning in
one side or the other)
Not affected by mechanical sensor or installation failures.
The disadvantage is that for correct operation sensor needed
always fill the gas cylinder completely (as much as the protective valve allows)
and after refueling, press two buttons simultaneously on the control panel.
Using this sensor in the gas equipment installation center, the master setting up
Your vehicle must enable this feature.
It is important to know that for the first time, having filled the cylinder completely with gas, you must simultaneously press two buttons on the control panel and hold until the sound
signal. After the first filling of the cylinder, the sensor operates in the mode
"REFERENCE MEASUREMENT" and no information about
level of gas in the cylinder, and on the control panel all green and
red LEDs. After the first refueling, it is necessary to use all the gas to the end,
until the system automatically switches the car to petrol, i.e. when the yellow LED on the control panel turns on and a constant sound signal sounds, which can be turned off by pressing the “P” button on the control panel.
Each next time, for the correct operation of the sensor, it is necessary to fill with gas
cylinder completely and simultaneously press the two buttons until the beep sounds.
It is not necessary to use all the gas to the end. Only after the second refueling
the “WORKING” mode of the level sensor is activated and the control panel displays
remaining gas readings.
This Instruction for the operation of gas protection (hereinafter referred to as the Instruction) is mandatory for employees involved in the adjustment, technical and operational maintenance of gas protection devices in the power systems of the Russian Federation.
The Instruction describes the principles of operation and provides the designs and technical data of gas and jet relays used in power systems, as well as methods for technical and operational maintenance of protection with these relays. Information is given about the shut-off valve and the oil level control relay in the expander, since these elements are functionally part of the gas protection circuits. Description and technical data of expired and obsolete relays PG-22 and PGZ-22 are excluded from the Instruction, which are recommended to be replaced by relays modern designs. Also excluded is an appendix on the replacement of reed switches in a relay made in Germany in connection with the termination of the activity of NTTM "Poisk" - a manufacturer of elements of the reed switch holder. The Instruction includes a description of the design and instructions for commissioning and maintenance during operation of the new domestic gas relays RGT80 and RGT50 and the jet relay RST25.
To characteristic damage oil-filled electrical apparatus - a transformer, autotransformer, reactor (hereinafter referred to as the transformer) include short circuits (short circuits) between the windings, coil short circuits, "fire" of the steel of the magnetic circuit, oil leakage from the tank, malfunctions of the oil-filled contactor of the tap changer of the voltage regulation device under load (OLTC) and etc.
Almost all damage inside the tank of an oil-filled electrical apparatus is accompanied by the release of gas as a result of the decomposition of oil or other insulating materials under the action of partial electrical discharges, increased heating, electric arc. During a short circuit, an accelerated flow of oil or its mixture with gas from the tank of the apparatus into the expander occurs. During operation, it is also possible to reduce the oil level or release gas for various reasons.
Contactor malfunction can be caused by damaged insulation, weakened mechanism springs, aging of ceramic power contacts, which leads to slowdown and fuzzy switching. A protracted arc is accompanied (taking into account the small volume of oil in the contactor tank) by the rapid decomposition of the oil. A jet of oil mixed with gas is directed from the contactor tank to the expander.
Gas relays are designed to protect transformers with an expander from damage inside the tank, in which there is a release of gas, a decrease in the oil level, or the occurrence of an accelerated flow of oil from the transformer tank to the conservator.
Jet relays are designed to protect the contactors of oil-filled transformer tap changers from damage, accompanied by the occurrence of an accelerated flow of oil from the contactor tank to the expander.
In case of internal damages in the transformer, even the smallest ones, gaseous decomposition products of oil or organic insulation are released, which ensures the operation of gas protection at the very beginning of the onset of a gradually developing damage. In some cases of dangerous internal damage to transformers ("fire" of steel, interturn short circuits, etc.), only gas protection, a electrical protection transformers do not work due to insufficient sensitivity.
Gas relays have a hermetically sealed housing installed in the oil pipeline between the transformer tank and the conservator. Figure 1 (not shown) shows a simplified sketch of a design option for such a relay. The reacting relay unit has three main elements: signal 1 and shutdown 2, 3 (elements 1 and 3 - floats, 2 - pressure plate), each of which works under certain conditions.
Under normal operating conditions, the relay case is filled with oil, and the elements take up a position in which the contacts they control (not shown in the figure) are open. With a slight gas formation in the transformer tank, the gas passes through the oil pipeline into the expander, accumulating in the upper part of the relay housing, where the signal element 1 is located.
When accumulated in the relay a certain amount gas, the oil level in it decreases, the float of the signal element 1 falls under the action of gravity and the signal contact closes; similarly, the signal element of the relay is triggered when the oil level in the relay drops for other reasons.
With a further decrease in the oil level, when the relay housing is more than half empty, the float of the disconnecting element 3 also falls under the action of gravity and the disconnecting contact closes.
In the event of a short circuit inside the transformer tank, under the action of an electric arc, a rapid decomposition of the oil occurs, and the flow of oil or a mixture of oil and gas rushes at high speed from the tank to the expander (arrow in Figure 1). Under the influence of this flow, plate 2, which has an adjustable oil flow rate setting, deviates to a certain angle and the tripping contact closes. Depending on the type and development of the transformer damage, sequential or simultaneous operation of the signal and tripping elements of the relay is possible.
With rapid gas formation and sharp jolts of oil, the contacts may rebound after operation, so the gas relay must act to turn off through an intermediate relay according to a self-holding scheme.
Jet relays, unlike gas relays, do not have floats and their contacts are triggered to turn off the transformer under the action of a pressure plate, which is similarly gas relay has an adjustable oil flow rate setting. The design of the jet relay usually provides for fixing the pressure plate after actuation in the final position until it is manually released, which increases the reliability of the relay operation under conditions of a less stationary flow of an oil-gas mixture compared to the flow in a gas relay.
The use of jet relays that do not have floats is due to the peculiarity of the operation of the contactors of the on-load tap-changers. AT normal operation contactor under the influence of an electric arc at the moment of switching, a small amount of oil is decomposed and gas is released from it, which passes through the pipeline into its expander or into the compartment of the common expander and then through it Airways goes out into the atmosphere. It is normal for a small amount of combustible gas to escape from the oil during contactor operation.
Diameter through hole the connecting flange of the gas relay must correspond to the inner diameter of the pipeline from the tank to the expander. The jet relay must be installed in an oil line with an inner diameter of 25 mm and as close as possible to the contactor. Diameter mismatch can lead to failure of actuation, for example, failure of the lower float when oil is lost, or a change in the oil flow rate of the pressure plate actuation compared to the set point.
The cover of the transformer (reactor) must have a rise towards the expander and, therefore, to the gas relay of at least 1%, and the oil line to the expander - at least 2%. To lift the transformer cover from the side of the expander, metal linings are used under the transformer rollers.
This manual is not a professional setup manual, this is a household HBO operating manual.
Vacuum (for a carburetor) or electronic (for an injector) two-stage gearbox is designed to operate on liquefied petroleum gas fuel (propane-butane). From a cylinder gas under pressure of 16 atm. goes to gas valve, where it is cleaned from resinous substances and mechanical impurities. Further, the purified gas passes into the first stage of the reducer, where the pressure is reduced to 2 atm., and then to the second, where it is reduced to 0.5 atm.
Under the action of vacuum created in the collector of a running engine, gas from the cavity of the second stage of the reducer enters the tee-dispenser. From the tee-dispenser through a mixing device (spacer, mixer or nozzles) to the carburetor chambers or injection device, where a homogeneous combustible mixture is formed, which enters the engine cylinders. The coolant from the engine block through the adapter enters the lower reducer pipe, heating the gas and improving its evaporation.
The procedure for launching HBO into the operation of a carburetor car
- Starting a cold engine is necessary (at temperatures below + 7-10 degrees) and preferably, in principle, to produce on gasoline, followed by warming up to a temperature of 40-50 degrees. Then the switch (switch in the cabin) is moved to the middle position, gasoline is produced from the float chamber. As soon as the car starts to work intermittently, move the switch to the "gas" position. It is allowed to start a warm engine on gas.
- RPM idle move adjustable with a screw located on the gearbox housing. The gas flow rate is regulated by screws on the tee-dispenser. After the initial adjustment made by the master of the installation center, the flow-dynamic characteristics can be improved as follows: screw 1 regulates the gas supply to the first chamber of the carburetor, which affects the dynamic characteristics of the machine during acceleration and partial loads. Accelerate the car to 80 km / h, and if the “reception is good”, tighten the screw 1 half a turn, repeat the procedure until the car starts to “dull”, then unscrew the screw 1 a quarter of a turn back. Screw 2 controls the second chamber of the carburetor, the degree of filling of which determines the throttle response at full loads. To adjust the second chamber, accelerate the car over 90 km/h and repeat the procedure described above. Because the density of the gas (kg/l) is less than the density of gasoline, gas is consumed by 10-15% more. When parking overnight, the car should be converted to petrol. To do this, increase the engine speed to 3000-3500 rpm, switch the switch (switch) to the “gasoline” position, bypassing the development, and wait for the float chamber to fill with gasoline.
The procedure for starting an injection car
The injection car is equipped with a two-position automatic switch (switch) gas-gasoline. When the switch is in the petrol position, the machine runs on petrol only (the red warning light on the petrol sign is on). To convert a car to gas, you need the following:
1. Switch the switch to the gas position.
2. Start the engine and warm it up to a temperature of 40-50 degrees. At the same time, the lamp of the petrol symbol on the switchboard lights up red, the green lamp on the gas symbol flashes (rev standby mode).
Z. To switch to gas, you must press the accelerator pedal and gain 2500 rpm and release it sharply. The car switched to gas (the green lamp on the gas symbol is on, the red one is off).
Basic safety requirements
- In the case when the power is not satisfied, increased consumption, idling problems, prohibited self-adjustment car (incorrect regulation can cause popping (injector only) and, as a result, failure of the mass air flow sensor, air filter housing, intake manifold). In this case, you should contact the service station.
- Injector: it is forbidden to operate the car until the gas from the cylinder is completely depleted (a lean mixture can cause popping). It is recommended to leave 10%.
- It is recommended to change the air filter at least every 5-6 thousand km.
- It is necessary to drain the condensate (plastic screw-plug on the gearbox housing) every 1000 km, but no later than 1500 km.
- Injector: if there is a pop, you need to switch the switch to the petrol position (only the red lamp will be on) and come for a consultation at service center.
- Injector: it is forbidden to operate the car on gas when there is no gasoline in the gas tank. An air lock can lead to the failure of the fuel pump (the minimum balance is 7-10 liters).
- When the car is running on gas, the petrol valve is in the closed position (OFF), therefore, if the electrical system fails, both the gas supply and gasoline are interrupted. In this case, it is necessary to check the HBO fuse and, if it is faulty, replace it. If the fuse is good, the electrical system is checked as follows:
when the switch is switched to the “gas” position (or the “gasoline” position), the corresponding solenoid valves should make a characteristic click. If this does not happen, the system is faulty. In this case, it is necessary to transfer the switch to the middle position (development), screw in the screw for the mechanical opening of the gas valve and come to the technical center. It is strictly forbidden to keep the gasoline valve open when the electrical system is working, because this leads to the simultaneous supply of gas and gasoline to the engine, which is unacceptable.
- for the optimal composition of the air-fuel mixture, it is recommended to change the air filter at least after 7000 km of run.
— It is recommended to use an air filter with as little airflow resistance as possible.
- replace spark plugs every 10,000 km (a spark plug producing less than 3-4 pulses does not ignite the gas-air mixture in the engine cylinder).
- drain the condensate from the gearbox every 1500 km by unscrewing the screw on the gearbox housing.
- After every 500 km driven by a car on gas, drive 15-20 km on gasoline, which contributes to the deposition of lead oxide on the valves and seats, preventing their additional wear, and also reduces wear on the diaphragms and clogging of the carburetor.
General safety requirements
— Carry out a daily check of the coolant level (antifreeze).
— In case of detection of leaks or damage to HBO, close the main valve of the multivalve on the cylinder and come to the service center. It is forbidden to tighten nuts and connecting pipelines under gas pressure.
- It is forbidden to start the car on gas with the choke removed, this will shorten the life of the main membrane or cause a rupture.
- It is forbidden to leave a car fully filled with gas in the sun without first using a few liters.
- It is forbidden to operate HBO if external mechanical damage is detected.
- It is forbidden to continue driving the car on gas if you detect the smell of gas in the cabin.
– When installing and dismantling any HBO units on your own, as well as when preserving a car for long term(more than a month), it is necessary to close the filling and main valves on the cylinder multivalve.
Successful operation!

Operating instructions for cars, trucks and buses for operation on liquefied petroleum (LPG) and compressed natural (CNG) gases.
1. INTRODUCTION
This manual applies to cars, trucks and buses of all modifications, domestic and foreign production with "carburetor" and "injection" engines, equipped with LPG equipment (hereinafter referred to as LPG) from LOVATO, BIGAS, TOMASETTO, ZAVOLI and other manufacturers and establishes a general methodology and procedure for operation and maintenance.
2. WARNINGS
2.1 The car is designed for operation in the CIS of the PA or PBA brands in accordance with GOST 27578-87,
CNG or gasoline.
2.2 It is not allowed to operate the engine with the simultaneous supply of gas and gasoline.
2.3 To maintain the normal performance of the gasoline power system and extend the life of the rubber products of the gas reducer, it is recommended to start and warm up a cold engine on gasoline, followed by switching to gas.
2.4 Stop the engine by turning off the ignition. When the car is put in for repairs or for a long parking, it is necessary to exhaust gas from the system, for which, when the engine is running on gas in idling mode (out of enclosed space) close the flow valve of the multivalve (if it is LPG) or the valves on all cylinders (if it is CNG) and wait for the engine to stop. To avoid damage to the seals, close the filling and flow valves of the multivalve (LPG) and cylinder valves (CNG) only by hand, without the use of any tool.
2.5 Perform maintenance or repair of LPG, as well as other components and assemblies of the vehicle, only after gas is produced from gas system supply, with valves closed.
2.6 Repair the cylinder or multivalve only after draining the gas (LPG) or bleed (CNG) in a safe place, and then purging with air or neutral gas.
2.7 Fill cylinders at gas filling stations AGNS and CNG filling stations in compliance with the relevant rules of these stations.
2.8 When operating the vehicle, pay attention Special attention on the tightness of all connections of gas pipelines and gas equipment, connections of gasoline pipelines (gasoline leakage is in 90% of cases the cause of ignition of cars with LPG), the condition of the insulation of the electrical wiring related to HBO, the condition of the hoses supplying antifreeze to the evaporator reducer (the efficiency of evaporation and gas heating and in the absence of the proper coolant level in the system in the evaporator reducer, airlock, leading to freezing of the gearbox and stopping the car on gas.
2.9 It is not allowed to operate a car with an expired test (re-examination) of cylinders. Cylinders are subject to periodic examination within the time limits specified by the "RULES", which is carried out at special test stations that have the permission of the Gosgortekhnadzor authorities. The date of the next test and the brand are applied on the cylinder plate.
2.10 Before checking the electrical equipment on the car, make sure that there is no gas in the engine compartment of the car and the surrounding area. Perform maintenance or repair of electrical equipment only when the battery. Do not allow unreliable fastening of contacts, as well as uninsulated ends of live wires, in order to avoid sparking or short circuit.
2.11 Do not allow persons who do not have sufficient qualifications in this area to repair and adjust HBO.
2.12 In case of fire, if possible, close the flow valves on the cylinders and, having developed gas at increased engine speeds, turn off the ignition. Extinguish the flame with a powder or carbon dioxide fire extinguisher, sand, rags, clothing.

at the gas filling station there is a euro-version and the Russian standard (to connect the Russian version, use an adapter that you can purchase after installing LPG).
GAS CYLINDERS.
Cylinders for gas are subject to periodic examination in organizations that have permission from the bodies of Gostekhnadzor. The frequency of inspection of cylinders for LPG is 2 years, for CNG - 5 years. According to the results of the survey, a mark is made in the passport of the cylinder
(if any) and the next test date is stamped on the cylinder label or directly on the cylinder body.
GAS SOLENOID VALVE.
The gas solenoid valve (EMK gas) is located in the engine compartment of the vehicle and is designed to shut off the gas supply from cylinders to gas reducer. The composition of the gas valve, as a rule, includes a gas purification filter (felt or paper) - it needs periodic cleaning and, if necessary, replacement. Failure of the gas EMC leads to the impossibility of supplying gas to the gas reducer. The reason for the failure may be the failure of the valve coil, the complete clogging of the gas filter, as well as the lack of voltage on the coil contacts in the mode of vehicle operation on gas.
PETROL SOLENOID VALVE.
The gasoline solenoid valve is located in the engine compartment of the vehicle and is designed to shut off the supply of gasoline to the carburetor while the engine is running on gas. It has an emergency opening valve that allows you to continue, if necessary, driving on gasoline, regardless of the performance of the valve itself. Does not require maintenance. It is necessary to periodically check the hoses for supplying and discharging gasoline to the valve and control the tightness of the hose clamps, excluding possible leakage of gasoline that could cause a fire in the engine compartment. Absent in HBO systems for injection engines.
REDUCER-EVAPORATOR.
Located in the engine compartment A / M. Designed to reduce the pressure of gas coming from a cylinder, evaporation (LPG) or heating (CNG) and provide the required amount of gas for the engine in any operating mode. Connected to the "small circle" of the engine cooling system using hoses and clamps. The principle of operation of gearboxes different manufacturers similar, only difference in design. Needs periodic cleaning from internal tarry deposits (a consequence of low-quality LPG gas), draining gas condensate (every 5000 km after the engine has stopped, through the condensate drain hole located in the lower part of the gearbox), if necessary, the rubber products of the gearbox are replaced (on average every 60,000 kilometers). It is necessary to monitor the reliability of fastening the gearbox, the condition of the hoses supplying coolant to it, and tightening the hose clamps.
GAS DISPENSER.
It is located on the hose between the reducer-evaporator and the gas-air mixer. In systems with lambda regulation, it can be made in the form of a stepper motor. It is single pass and double pass. The principle of operation is similar faucet- it blocks the passage gas hose, allowing you to adjust the desired amount of gas entering the engine.
GAS-AIR MIXER.
It is applied in ejection systems. In carburetor engines, there is an upper or lower location(depending on the connection point to the carburetor). Provides optimal preparation of the gas-air mixture before entering the vehicle engine. For injection engines, options are available for the joint arrangement of the mixer and the DMRV fuse (Sensor Fuse mass flow air - a device that minimizes damage to parts of the vehicle injection system and the air filter in the event of "reverse gas pops"). Care of the mixer consists in periodic cleaning of resinous deposits and control over the reliability of its fastening to each other. constituent parts. Not available in multiport gas injection systems.
FUEL SWITCH.
Located in the car interior. Made in the form of a three-position switch or touch key. Allows you to switch between "GAS" and "PETROL" modes with visual or audible confirmation from the driver's seat.
It may contain a reserve indicator and a gas level indicator in the cylinder.
DISTRIBUTED GAS INJECTION SYSTEM.
SRWG is a technically complex system that requires qualified maintenance and repair. In case of situations related to equipment failures or problems in operation, we recommend contacting a specialized service.
