New High Quality Diesel Nozzle F00VX20054 for Injection Nozzle Diesel Engine Parts

Whether the car's fuel injector needs to be cleaned can be judged from the working state of the engine, exhaust emissions, and the vehicle's power and fuel consumption performance, as follows:

Engine working state
Unstable idling: When the engine is idling, observe whether the tachometer pointer is stable. If the pointer shows obvious jitter, up and down fluctuations, or the engine is accompanied by intermittent jitter and panting, it is likely caused by the blockage of the fuel injector or uneven injection. Because the fuel injector failure will cause the fuel injection amount of each cylinder to be inconsistent, thus affecting the smooth operation of the engine.

Starting difficulties: Under normal circumstances, the car should start quickly and smoothly. If it is found that the engine is turning but not easy to start at the start, it takes multiple ignitions to succeed, or the engine speed is unstable after starting, and there is a tendency to stall, this may be due to the blockage of the fuel injector, resulting in insufficient fuel injection or untimely injection, so that the mixture cannot burn normally, affecting the starting performance of the engine.

Abnormal noise: The sound is stable and uniform when the engine is running normally. When there is a problem with the fuel injector, it may cause abnormal noise in the engine, such as knocking and knocking. This is because abnormal fuel injection will cause abnormal combustion process, resulting in abnormal combustion pressure fluctuations and noise.

Exhaust emission
Abnormal color: Normal automobile exhaust should be colorless or slightly gray. When the fuel injector fails, resulting in incomplete fuel combustion, the exhaust may appear black, because the unburned fuel forms carbon particles at high temperature and is discharged; if the exhaust is blue, it may be due to the combined effect of the fuel injector failure and the failure of components such as the piston ring and valve oil seal, causing the oil to enter the combustion chamber and participate in the combustion, resulting in the phenomenon of burning oil.

Strong odor: If the exhaust emits a strong gasoline smell, it means that the fuel is discharged without being fully burned. It is likely that the fuel injector sprays too much fuel or the fuel injection atomization is poor, so that the fuel cannot be completely burned in the cylinder, and the unburned fuel produces a strong gasoline smell after being discharged.

Vehicle power and fuel consumption performance
Power reduction: During driving, the vehicle feels weak and slow to accelerate, the engine is slow to respond during rapid acceleration, the speed does not rise smoothly, and it is difficult to reach the expected speed even if the accelerator is pressed deeply. This may be due to the fuel injector being blocked or the fuel injection being poor, resulting in the fuel not being supplied in a timely and sufficient manner, affecting the engine's power output.

Fuel consumption increases: When there is a problem with the fuel injector, such as excessive or uneven fuel injection, the fuel cannot be effectively involved in combustion, resulting in fuel waste, which leads to a significant increase in fuel consumption. If you find that the vehicle's fuel consumption is significantly higher than usual, but the road conditions and driving habits have not changed, you need to consider whether the fuel injector needs to be cleaned.
