Depending on the condition of the vehicle and the quality of the fuel you usually add, generally speaking, it is now recommended to clean it at around 20,000 to 30,000 km. If the vehicle is in good condition and the fuel quality is good, it can be extended to around 40,000 to 60,000 km. When the fuel injector is slightly clogged, it will also have a certain impact on the vehicle condition.
Necessity of cleaning
After the fuel system has been working for a period of time, the carbon deposits and colloids formed by combustion will adhere to the fuel injectors, causing the fuel injectors to become sticky or even clogged. Impurities and dust in the air and gasoline will also cause the oil path to be blocked or clogged, and eventually form carbon deposits and sediments on the fuel injectors. The formation of carbon deposits and sediments is inevitable, but poor fuel quality, long-term idling of the engine, and other reasons will lead to faster clogging of the fuel injectors.
The working quality of the fuel injectors plays a fundamental role in the power of each engine. Poor fuel quality causes the fuel injector to malfunction, resulting in serious carbon deposits in the cylinder; the cylinder barrel and piston ring wear faster, causing unstable idling, increased fuel consumption, weak acceleration, difficulty starting and excessive emissions. In severe cases, the fuel injector will be completely blocked and the engine will be damaged.

Since the diesel engine injector is a high-precision device (the needle valve pair inside the injector, the plunger pair of the injection pump, and the oil delivery valve pair are together the three major high-precision pairs of the diesel engine), if there is not extremely high installation accuracy and installation conditions, it will be impossible to restore it once disassembled. Therefore, when the injector fails, be sure to go to a professional 4S shop for processing.
