HBO for 4 generations: self-tuning. Gas-cylinder equipment on the car

Installed gas-cylinder equipment on the car significantly reduces the cost of gasoline. But is propane or methane suitable for all engines? Will not reduce the life of the ICE? Experts assure that properly selected and adjusted equipment will not harm the engine, and the owner will really help to save.

How much does HBO cost?

The cost of gas-cylinder equipment on the car depends on the kit. It includes:

• electronic control unit;
• Reducer;
• balloon;
• A refueling device;
• Multivalve;
• filter;
• Injectors;
• The highway;
• Toggle button.

For each engine, a kit is selected from either a single manufacturer or a prefabricated one. For example: an ECU from Stag, and a reducer, a balloon and an injector - from Lovato.

The price of HBO is affected not only by its layout, but also by the type of cylinder. It can be cylindrical in shape - installed in the trunk, or toroidal - for mounting in a niche instead of a spare wheel. The latter is more expensive.

The more powerful and complex the engine, the more expensive the HBO will be. The price of equipment is from 11 thousand rubles.

How to choose the right equipment for your car?

Owning an auto that has not previously encountered gas equipment, it will be difficult to determine its choice. To avoid problems with the engine in the future, it is necessary to entrust the selection, installation and configuration of HBO to the proven specialists. According to the characteristics of ICE, they will select the necessary equipment and consult in the field of operation.

It is worth considering that the gasoline engine is not designed to work with gas. Therefore, car manufacturers, installing factory gas equipment, also make changes in the engine, adjusting it to work on gas.

Pros and cons of HBO installation

Taking into account the responses of drivers, it is possible to formulate the advantages and disadvantages of gas-cylinder equipment on cars.

Positive sides:

1. Significant savings at the gas station. Whatever the prices for fuel, gas is always cheaper than gasoline and diesel. The HBO price pays off a year after its installation.
2. Low load on the motor. The gas has a higher octane number, correspondingly, it burns longer, reducing the load on the ICE. The "gas + air" mixture is more even, does not dry the cylinders, does not affect the consistency of the oil, which increases the service life of the motor.
3. Minimal damage to the environment. In the waste gas contains two-thirds less harmful substances than in the exhaust from gasoline or diesel.
4. Increase kilometer from refueling to refueling. The car works on two types of fuel, respectively, when gas ends, you can go on gasoline.
5. Security. Rumors that the HBO balloon could explode from temperature changes or impact, disproved the car protection club of German car owners ADAC. Under his control crash tests of cylinders were conducted in the conditions of a fire and an accident. The results were satisfactory.

A few minuses:

1. Not every gas station has a gas station. Repair of HBO is carried out only on specialized service stations.
2. A slight decrease in speed, a drop in engine power by 15%.
3. Influence of high and low temperatures. If the car is heated under the sun, the gas pressure in the balloon increases. To reduce it, you need to work out a few liters. In the cold, the gas liquefies and refuses to enter the system. So in winter it is possible to start the engine only on gasoline.
4. An increase in the mass of cars. The entire design of the gas equipment adds to the weight of the machine 60 kg. The balloon, installed in the trunk, takes an average of 40 liters of space.
5. Gas leak. The probability of this is small, but is present, in case of misuse and untimely passage of maintenance.

Installation of HBO 4 generation

At a specialized station, the car owner will be offered a range of turnkey services: from the selection of HBO to installation and complete setup. Will give a guarantee and will consult. The price of the issue varies from 30 000 to 70 000 rubles.

Experts on experience know where to put the gearbox, how to connect the trunk line and carefully hold the supply and gas pipes.

You can install and configure the HBO 4 generation yourself.

Where to conduct work?

Gas equipment is installed on the overpass or in the pit box. It is necessary to have a set of tools, protective gloves and good lighting.

Selecting the location for fastening the gear unit

Necessary installation conditions:

• The installation site of the gear unit must be easily accessible for removing and replacing the filters;
• Mount the gearbox on the machine frame, not on the motor, to avoid vibrations;
• The hoses and tubes must not be twisted and twisted.

Estimating the length of the hoses and the accessibility, you can attach the reducer.

Features of connecting hoses for antifreeze:

• They are connected strictly parallel to the system;
• It is important to determine where the "entrance" and "exit" of the antifreeze are in the furnace;
• Hoses are connected (cut) to the shut-off valve by means of a tee.

Equipment for the place under the balloon

If a balloon is chosen for the tank, it is important to place it so that the gas supply and filling pipes are positioned correctly: they should not come into contact with the hot muffler or vibrating body parts.

The HBO balloon is fixed rigidly, the multivalve is located in its upper part.

Routing the main pipe

The main pipe is necessary for the gas to enter the reducer from the cylinder. Start the installation from the gearbox, on the bottom of the car (preferably along the gasoline wire) and then connect to the multivalve.

Installation of injectors

First it is necessary to cut the fittings as close as possible to the gasoline nozzle, after which the gas nozzles are installed. Then connect the hoses for gas supply. They should be the same length, but not more than 18 cm.

Arrangement of the control unit and sensors

All electronics is installed under the hood. For the correct connection with the HBO, there is an instruction in which all the wires and contacts are described.

After the installation is finished, we start the car. The first three times we turn the key in the ignition, without starting the engine. This is necessary in order for the gasoline pump to create the necessary pressure in the ramp. After that, the car can start. If everything is done correctly, then the next step will be setting up the 4-generation HBO with your own hands.

Than to adjust?

To adjust the parameters of freshly installed gas equipment, you will need a laptop, a program for setting up a 4-generation HBO and a special cable.

There are many programs, such as Zenit JZ, KME NEVO or STAG. They are similar in appearance (interface), any one can be downloaded from the official site and installed. Consider the program for setting HBO 4 generation STAG.

Its interface is quite functional. The instructions for setting up the HBO 4 generation are simple and understandable. The meaning of each parameter is deciphered in additional footnotes that pop up when the cursor is hovered.

The values stored in the HBO factory are displayed immediately. If the gas equipment is not new, the information from the controller will be displayed in the program. Here it will be indicated how often gas was used, how many times they performed diagnostics and tuning.

If there is a new firmware of the controller, the program will immediately prompt you to install it.

The cable for tuning HBO 4 generation can be bought, and you can do it yourself on the basis of the PL2303 card.

Settings

In the main window of the program are the main indicators on which the computer works:

• Conditions under which there will be a switch from gasoline to gas or vice versa (temperature, engine speed, pressure);
• Gas fraction (gas pressure after the reducer);
• Discharge in the collector;
• Period of injection of gas and petrol injectors.

The tab "map" shows the schedule of gasoline (blue curve), gas injectors (green curve) and the conversion factor of the gasoline injection to the gas (orange line).

On not adjusted gas equipment in time, the control unit will fully simulate the operation of the gasoline injectors, which will give an error on the on-board computer. The reason is that the mixture of gasoline and gas injectors will be the same, and the fuel in the octane number is different: that for gasoline is good, then for gas - it is incorrect.

Calibration

At idle, the gas is turned off. The gas ECU measures and remembers the operation parameters of the petrol injectors. Then the work of one petrol injector is replaced by the functioning of the gas injector. Gradually, all gas injectors are turned on.

By alternately increasing and decreasing the injection time of the gas injectors, it is necessary to bring the exhaust to normal (conversion factor). To obtain the value of the gas injection time, this coefficient is multiplied by the gasoline injection time.

After calibration, the machine automatically switches to gasoline. You need to drive through it to check the settings.

Adjusting the graphs

After self-tuning of the HBO for 4 generations, it is better not to remove the gasoline card. The car will go to gas after checking. If the card is removed, it will have to travel temporarily on gasoline, changing the load on the engine and the revolutions, until the system makes a new card.

After a trial trip, it is recommended to save the settings log. This will allow you to view data about the operation of the equipment and, possibly, to find errors.

If the schedules of gasoline and gas injectors diverge, then a 4-generation HBO card setup is necessary. To do this, on the orange line, we fix the points of divergence and the closest approach of the green and blue lines - the settings at these points are considered optimal and should not change. Then, on the orange line, we mark the point of maximum divergence of the gas and gasoline lines and lower it by the distance of the line divergence.

We pass on the car in different modes and see if the graphics match. If not, then repeat the map settings until the graphics match.

Adjustment of injection of fuel

Injection adjustment is the second most important phase in configuring the HBO of the 4th generation with your own hands.

First, we warm up the car to the operating temperature of the gearbox. Switch to gasoline and for five minutes we observe the injection indicators of petrol injectors. We turn on the gas again, but we continue to observe the gasoline indicators. If the number has increased, it means a poor mixture, if decreased - enriched.

You can change this state by adjusting the orange line of the graph: if the mixture is poor - raise the line by two clicks, if the mixture is excessively enriched - lower it.

The adjustment of the gas-cylinder equipment on the car is finished. If the system GBO works without interruptions: the switching between the injectors occurs in time and smoothly, the engine does not trip, has a good dynamics - this means that the settings were carried out correctly. After some time of operation, it is possible to re-conduct the diagnostics.

Adjusting the gas regulator of HBO

Reducer is an essential element in the design of gas equipment. With its help, the pressure of the gas entering the cylinder is regulated. With stable gas consumption, the gearbox keeps the pressure at the same level, although with a sharp increase in the flow rate, the pressure may decrease, but insignificantly.

Adjustment of the gearbox is necessary when installing new equipment. And after 100 000 km it is worthwhile to re-conduct its diagnostics and correct it.

The correct operation of the HBO depends not only on the quality of its electronic configuration. After some period of operation (3 or 4 years), the valves and membranes can be worn out, which will lead to a gas overflow.

To postpone this moment it is possible to properly operate the HBO (gearbox in particular): the engine start must take place on the native fuel of the car (gasoline or diesel). С, Only after the temperature of the motor reaches at least 30 ° C, You can switch to gas. At low temperatures, the reducer membrane can freeze. That is why the reducer is connected to the trunk lines.

The 4-generation HBO gearbox in the self-tuning is not quite simple. There are two ways to adjust: adjust the sensitivity and adjust the amount of gas in the idle channel.

Before starting the adjustment, the engine should be warmed up, and then cut off the gasoline supply, allowing the engine to process the remaining fuel.

Idle speed adjustment:

1. Set the power register to maximum.
2. Completely wrap the idle screw, and then unscrew it for five turns.
3. The sensitivity control is brought to the middle position.
4. We start the car on gas and increase the speed by sucking up to 2000.
5. Simultaneously, remove the suction (very slowly) and idle regulator we are looking for that moment when the starter reaches the maximum speed.
6. We remove the suction completely. Should get a stable idling.
7. Smoothly adjust the sensitivity knob.
8. The floating turns are raised to maximum by the idle speed regulator.
9. The regulator did not help - twist the sensitivity screw for a couple of turns and repeat everything anew.
10. We achieve 1200 revolutions at idle speed, and then gradually reduce the idling speed to 950.

Setting the sensitivity of the gearbox:

1. Very slowly unscrew the sensitivity knob before changing the idling speed.
2. As soon as the speed has changed, turn the regulator quite a bit back.
3. Check the setting: sharply click on the accelerator pedal. The engine should immediately react - without jerks and delays.

Regulating the power register:

1. We bring the speed of the starter to 3500, twisting the power regulator.
2. As soon as the turns begin to fall, we stop the procedure.

Checking the quality settings:

1. We sharply press the accelerator pedal.
2. We twist the sensitivity control by a quarter until the starter's speed starts to drop sharply.
3. We unscrew the regulator for half a turn and let the engine idle.

If the configuration of the 4-generation HBO is done correctly by itself, the ICE will work smoothly and stably.
