How often do diesel fuel injectors need to be replaced?

If there is a problem, change it because of the high cost. Moreover, the original factory or the original factory must be replaced. If you change to a deputy factory, there will be many problems. If the nozzle is replaced or replaced, the decoder must be used for matching, otherwise there will be unstable idle speed or other problems.

In order to reduce the maintenance burden, this kind of nozzle can be repaired, that is, it is more cost-effective to replace the accessories in the chicken shoes and cats, each of which costs only a few hundred yuan, and it is guaranteed.

Effect of carbon deposition

As one of the key components of EFI engine, the performance of injector will be seriously affected. Nozzle blockage will seriously affect the performance of the car. The reason for the blockage is that carbon deposits in the engine are deposited on the fuel nozzle or impurities in the fuel block the fuel nozzle channel. After the car runs for a period of time, the fuel system will form certain deposits.

The formation of deposits is directly related to automobile fuel: firstly, because gasoline itself contains colloid and impurities, or dust and impurities brought in during storage and transportation, deposits similar to sludge are formed in automobile fuel tanks and oil intake pipes over time; Secondly, the unstable components in gasoline react at a certain temperature to form colloid and resin-like viscous bodies.
