What advantages and disadvantages will you notice when installing HBO on UAZ Patriot? This question worries many, since 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 are so tiny that they are not even considered an alternative to gasoline. Yes, and the cost of servicing an electric car is several times higher - batteries alone can have a cost of 75% of the total.
Advantages and disadvantages of HBO
It should immediately be noted that the installation of 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 advantages - fuel consumption for fuel is reduced (and the Patriot is not a car from small cars), the engine's operation becomes quieter, any, even the smallest, knock knocks disappear.
Some skeptics argue that running a gas engine means that "piston rings are not lubricated with gasoline." This is the opinion of amateurs, since the rings are lubricated with engine oil. And all gasoline burns out, leaving only soot behind (it depends on the quality of the fuel). And so this soot will not lubricate the surface of the cylinder, it will quickly destroy it. Engine power when powered by gas fuels can drop, but not more than 3-4%. A gas bottle in the trunk is a minus, but there is enough space in the Patriot to install it and not feel discomfort.
The first generation of HBO
For the UAZ "Patriot" car, the HBO of the 4th generation is ideal. We need to consider the reasons why the choice falls on him. 2nd generation is designed for carburetor engines. It has a minimal number of components, all controls are exclusively 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 supplied. But the parameters are far from an ideal system.
4th and 5th generations: which is better?
The fourth generation is the maximum implementation 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 a reducer-evaporator, a special design of the pump is used. Its cost is very high - over $ 1,000. Repairing such a device will be quite expensive. The most effective is the use of the fourth generation of HBO.
HBO work
The functioning of HBO 4 at the UAZ "Patriot" is as follows:
- With the ignition switched off, the gas cylinder is closed, fuel is not supplied through the line to the gearbox.
- After turning on the ignition, all sensors of the system are interrogated. If the temperature of the gearbox is lower than 35 degrees, the gas cylinder remains open, the gas-gasoline switch is switched to the second position (gasoline supply).
- Upon reaching 35 degrees, the gearbox housing smoothly switches the types of fuel. The valve on the gas cylinder opens, the switch on the gearbox switches to the "Gas" position.
- The HBO begins, according to the fuel card embedded in the control unit.
Control block
HBO on UAZ "Patriot" (feedback on the installation only positive) has a separate control unit. It controls the operation of the nozzles, by which the fuel is supplied to the combustion chambers. Moreover, one peculiarity should be noted - gas has an octane number higher, therefore, it is necessary to correct the UOZ. This is done quite simply - the nozzle opening time is increased. In order to calculate the coefficient by which this indicator needs to be increased, an initial calibration is performed (immediately after the installation of the gas cylinder).
Sensors and actuators are connected to the HBO 4 control unit at the UAZ Patriot:
- Throttle position.
- Idle move.
- The position of the crankshaft.
- Vehicle speeds.
- Positions of the gas-gasoline switch and cylinder valve.
- Electromagnetic gas injectors.
- Gas nozzles.
- Pressure in the cylinder, line, fuel rail.
- Reducer and coolant temperatures in the system.
Please note that a nozzle from the cooling system is connected to the HBO reducer-evaporator at 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 types of fuel - for this there are buttons that are in the cabin (usually they are combined with a gas level indicator in the cylinder).
Conclusion
You learned about the pros and cons of HBO 4 at UAZ Patriot. One thing is clear - there are many more advantages than disadvantages. Significant fuel savings, no power losses, engine life is not reduced. The main thing when installing equipment is to correctly install and configure everything. It depends on the calibration, what kind of consumption will the car have, what will be its power and throttle response. 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. Or vice versa - power and dynamics are maximum, and consumption is greater than when working on gasoline (for money, and not just for displacement).
