My car is uphill and boring, 4102 with a supercharged engine, the car is five years old

According to your description, I personally think you should check from these aspects: 1 whether your engine has been hot, and the engine will definitely have a lack of power when going uphill; 2. Consider whether the supercharger is damaged? The supercharger was damaged, and the engine air intake was not smooth, but instead of supercharging, it blocked the air intake.

3. Considering whether the fuel is qualified, inferior fuel will also cause the engine power performance to decline; 4. Consider whether the fuel injector is blocked, the inspection method is very simple, the engine is running normally, loosen the high-pressure oil pipe in front of the fuel injector on the engine, and the engine runs and shakes after loosening 1, which proves that the oil supply of this cylinder is normal, and then tighten the high-pressure oil pipe, and then check the next cylinder. 5. The oil circuit is blocked, there is rust or other impurities in the fuel tank to block the oil pipe, or the diesel filter element has not been replaced for a long time, resulting in the filter element being blocked. 6. Fuel has water, and it will also be weak to climb.

7. Consider whether the air cleaner is too dirty, clean or replace it with compressed air at 4 pressures. 8. The clearance between the engine valve and the valve seat insert is too large, the engine piston ring or cylinder liner is worn too much, and the compression ratio is reduced. Check whether the engine oil has decreased or if the engine is emitting blue smoke.

9. The engine smoke exhaust is abnormal, and the blue smoke needs to be overhauled; Black smoke needs to be checked by 2--7; White smoke should be checked by 6. 10 you are severely overloaded!!

The engine oil system is where the car often has problems, and the fuel injector is blocked, the oil pipe is leaking, the gasoline pump power is reduced, and the gasoline filter is blocked.

The main reason why the car has a sense of powerlessness is that the engine does not have enough oil when going uphill, the combustion efficiency decreases, and the horsepower does not meet our requirements. In addition, the same is true for the air intake system, the engine needs air in addition to oil, if the air filter, throttle and other components are clogged or there is a problem, resulting in insufficient air intake, it will also cause the car to climb the hill weakly. Spark plugs are also a common source of failure, and if the spark plug is poorly ignited, it can lead to problems with weak acceleration.

If the car is not climbing and the steering wheel or body shakes significantly when it stops, then it is a sign that at least one cylinder of the car's engine is not running properly or stalling.

The 6-meter Eryangchai 4105 engine is uphill and weak, it is recommended to check whether the car has the problem of excessive engine carbon deposit, which may lead to excessive engine carbon deposit.

If you are not born, it may be that you need to do maintenance on the machine.

If the engine power is normal, it is a lot of goods. Its horsepower is limited, and you have to make sure that the traction is sufficient.

The main causes of black smoke are:

1.Insufficient cylinder pressure, i.e. low temperature at the end of compression due to cylinder leakage. (valves, piston rings, etc.) 2Poor atomization of oil injection. (caused by injectors, outlet valves, etc.) 3The air filter is clogged.

4.The booster boost pressure is insufficient.

5.The injection advance angle error is too large. (Adjustable).

According to your description, you should first check if the cylinder pressure is within the normal range. Then check the injection advance angle, and then check the injector, which can be done for spray testing or try with the replacement method. The oil outlet valve is not easy to change, you ask the oil pump repairer.

Or if you can borrow an oil pump, try it by the replacement method.
