New High Quality Diesel Nozzle DLLA152P2137 for Injection Nozzle Diesel Engine Parts

The cleaning cycle of the fuel injector of a car engine is not fixed. It will be affected by factors such as fuel quality, road conditions, and vehicle age. Generally speaking, it is recommended to clean it every 20,000 to 40,000 kilometers or 1 to 2 years. The following is a specific analysis:

Fuel quality
If the vehicle uses high-quality and clean fuel for a long time, the possibility of fuel injector clogging is relatively small, and the cleaning cycle can be appropriately extended, and it can be cleaned every 30,000 to 40,000 kilometers.
If poor quality fuel with more impurities is often used, the fuel injector is more likely to be contaminated and clogged, and it may need to be cleaned every 20,000 to 30,000 kilometers.

Driving road conditions
If the vehicle is mainly driven in an environment with good road conditions and smooth highways, the engine working state is relatively stable, and the fuel injector is not easy to produce too much carbon deposits and impurity precipitation. The cleaning cycle can be extended to 30,000 to 40,000 kilometers.

If the vehicle often drives on congested roads, the engine is frequently started and stopped, and runs at low speed, the fuel injector is more likely to form carbon deposits, and generally needs to be cleaned every 20,000 to 30,000 kilometers.

Vehicle age
Under normal use, the fuel injectors of new vehicles do not need to be cleaned too frequently in the first few years. You can consider cleaning them after driving 30,000 to 40,000 kilometers.

For older vehicles, the fuel injectors are aged and worn after long-term use, and are more likely to have carbon deposits and blockages. They may need to be cleaned every 20,000 to 30,000 kilometers or even shorter.

Engine condition
When the engine has unstable idle speed, poor acceleration, reduced power, significantly increased fuel consumption, and excessive exhaust emissions, it is likely that there is a problem with the fuel injectors. The fuel injectors need to be checked and cleaned in time. This situation may not be limited by mileage or time.
