What are the advantages and disadvantages you will notice by installing HBO on the UAZ "Patriot"? This question worries many, since the cost of gasoline is growing every month, so you need to look for some kind of alternative. The most efficient is gas (propane or methane). Electric vehicles occupy such a tiny share that they are not even considered as an alternative to gasoline. And the cost of maintaining an electric car is many times higher - batteries alone can have a cost of 75% of the total.

Advantages and disadvantages of HBO

It should be noted right away that the installation of HBO on the UAZ "Patriot" must 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 has up to 200 atm., Propane has up to 25 atm.). Therefore, gas is much more dangerous. But in general, you get a lot of advantages - the cost of money for fuel decreases (and the Patriot is not a car from minicars), the operation of the internal combustion engine becomes quieter, any, even the smallest, detonation knocks disappear.

Some skeptics claimthat the operation of the engine on gas leads to the fact that "the piston rings are not lubricated by gasoline." This is the opinion of amateurs, since the rings are lubricated with engine oil. And all gasoline burns out, leaving behind only soot (depending on the quality of the fuel). And this soot will not lubricate the surface of the cylinder, it will destroy it faster. Engine power when powered by gaseous fuels may fall, but not more than 3-4%. A gas bottle in the trunk is a minus, but in the Patriot there is enough space to install it and not feel discomfort.

First generation HBO

For the car UAZ "Patriot" HBO 4th generation is ideal. It is necessary to consider the reasons why the choice falls on him. The 2nd generation is designed for carbureted engines. It has a minimum number of components, all control is exclusively of a mechanical type, 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 injection engines can be installed. But the parameters are far from being an ideal system.

4th and 5th generations: which is better?

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

HBO work

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

1. When the ignition is off, the gas cylinder is closed, the fuel supply is not carried out through the line to the gearbox.
2. After the ignition is turned on, all sensors of the system are polled. If the reducer temperature is below 35 degrees, the gas cylinder remains open, the gas-petrol switch is switched to the second position (gasoline supply).
3. When the gearbox housing reaches 35 degrees, a smooth switching of fuel types occurs. The valve on the gas cylinder opens, the switch on the gearbox switches to the "Gas" position.
4. The operation of HBO begins, according to the fuel card embedded in the control unit.

Control unit

HBO on the UAZ "Patriot" (feedback on the installation is only positive) has a separate control unit. It controls the operation of the injectors, with the help of which fuel is supplied to the combustion chambers. Moreover, one feature should be noted - the gas has a higher octane number, so it is necessary to correct the UOP. This is done quite simply - the opening time of the nozzles increases. To calculate the coefficient by which this indicator needs to be increased, an initial calibration is performed (immediately after the installation of HBO).

Sensors andactuators:

1. Throttle positions.
2. Idling.
3. Crankshaft positions.
4. Vehicle speeds.
5. The positions of the gas-gasoline switch and the valve on the cylinder.
6. Electromagnetic petrol injectors.
7. Gas nozzles.
8. Pressure in the tank, line, fuel rail.
9. Reducer and coolant temperatures in the system.

Please note that a pipe from the cooling system is connected to the LPG evaporator reducer on the UAZ Patriot. This allows you to quickly warm up its body and make the transition to gas fuel. In addition, you can manually switch between fuel types - for this there are buttons that are located in the cabin (usually they are combined with a gas level indicator in the tank).

Conclusion

You have learned about the pros and cons of HBO 4 on the UAZ Patriot. One thing is clear - the advantages are much greater than the disadvantages. Significant savings on fuel, no power loss, engine life is not reduced. The main thing when installing equipment is to install and configure everything correctly. It depends on the calibration what consumption the car will have, what its power and throttle response will be. The HBO control unit can also be configured so that the car will consume very little fuel, but its characteristics (power and dynamic) will drop many times over. Or vice versa - the power and dynamics are maximum, and the consumption is greater than when running on gasoline (for money, and not justby displacement).
