HBO on UAZ "Patriot": advantages and disadvantages

What are the advantages and disadvantages you will notice when installing the HBO on UAZ Patriot? This issue is of concern to many, as the cost of gasoline is growing every month, so you need to look for some alternative. The most effective is gas (propane or methane). Electric cars take so little of their share that they are not even considered an alternative to gasoline. And the cost of servicing an electric car is many times greater - only batteries can have a cost of 75% of the total.

Advantages and disadvantages of HBO

It should immediately be noted that the installation of the HBO on the UAZ "Patriot" should be carried out by qualified specialists. Gas, like gasoline, is a combustible substance. But it has one feature - it is constantly under high pressure (methane up to 200 Atm., Propane up to 25 Atm.). Therefore, gas is much more dangerous. But in general, you get a lot of pluses - the consumption of money for fuel decreases (and "Patriot" is not a car from minicars), the engine's operation becomes quieter, any, even the smallest, detonation knocking disappears.

Some skeptics argue that the operation of the engine on gas leads to the fact that "the piston rings are not smeared with gasoline." This opinion of amateurs, since the lubrication of the rings is made with engine oil. And the whole gasoline burns, leaving only soot after itself (depends on the quality of the fuel). And this soot will not lubricate the surface of the cylinder, it will quickly destroy it. The power of the engine when feeding with gas fuels can fall, but not more than 3-4%. The gas cylinder in the trunk is a minus, but in the "Patriot" space is enough to install it and not experience discomfort.

First Generation of HBO

For the car UAZ "Patriot" HBO 4 generation will fit perfectly. We need to consider the reasons why the choice falls on him. The 2nd generation is designed for carburetor engines. It has a minimal number of components, all controls are purely mechanical, there are almost no electronics. The third generation is a kind of transitional link between electronic and mechanical devices. Here you will find more electronics, even on the injector engines you can put. But in terms of parameters is not an ideal system.

4th and 5th generations: which is better?

The fourth generation is the maximum implementation of electronic components, all control can be performed without human intervention, which gives you some freedom. The fifth generation is very similar to the fourth, but only with one difference - instead of the reducer-evaporator, a special pump design is used. Its cost is very high - over $ 1000. Repair of such a device will be quite expensive. The most effective is the use of the fourth generation of HBO.

The work of HBO

Functioning of HBO 4 on the UAZ "Patriot" is as follows:

1. With the ignition off, the gas cylinder is closed, fuel supply is not carried out along the main to the gearbox.
2. After the ignition is turned on, all sensors of the system are interrogated. If the temperature of the reducer is below 35 degrees, the gas cylinder remains open, the gas-gas switch is moved to the second position (gasoline powered).
3. When the 35 degrees of the gearbox body is reached, the fuel types are smoothly switched. The valve on the gas cylinder opens and the switch on the gearbox switches to the "Gas" position.
4. Begins the work of the HBO, according to the fuel card embedded in the control unit.

Control block

At ГБО on УАЗ "the Patriot" (responses about installation only positive) there is a separate control unit. It controls the operation of the injectors, by means of which the fuel is supplied to the combustion chambers. And it should be noted one feature - the gas octane number is higher, so you need to correct the UOZ. This is done quite simply - the opening time of the injectors is increased. To calculate the coefficient to which this parameter needs to be increased, an initial calibration (immediately after the installation of the HBO) is performed.

Sensors and actuators are connected to the control unit HBO 4 on the UAZ "Patriot":

1. Throttle Position.
2. Idle move.
3. The positions of the crankshaft.
4. Vehicle speed.
5. The positions of the gas-gasoline switch and the valve on the cylinder.
6. Electromagnetic gasoline injectors.
7. Gas injectors.
8. Pressure in the cylinder, main, fuel rail.
9. The temperature of the reducer and coolant in the system.

Pay attention to the fact that a branch pipe from the cooling system is connected to the reducer-evaporator of the GBO at UAZ Patriot. This allows you to quickly warm up its hull and make a transition to gas fuel. In addition, you can switch manually between fuel types - for this there are buttons that are located in the cabin (they are usually combined with the gas level indicator in the cylinder).

Conclusion

You learned about the pros and cons of HBO 4 on the UAZ Patriot. One thing is clear - there are many more advantages than disadvantages. Significant savings on fuel, no power loss, engine life is not reduced. The main thing when installing the equipment is to install everything correctly and set it up. It is from the calibration that depends on what the car's expense will be, what will be its power and throttle response. The HBO control unit can be configured and so that the car will consume very little fuel, but its characteristics (power and dynamic) will fall many times. Or vice versa - the power and dynamics are maximum, and the consumption is greater than when working on gasoline (for money, not just for liters).
