What is the normal service life of fuel injectors in electronically controlled diesel vehicles?

[Margot]

Fuel injectors are precision instruments with electromagnetic mechanisms and have a relatively long service life, typically around 200,000 kilometers. Below is relevant information: 1. Introduction: A fuel injector is essentially a simple solenoid valve. When the electromagnetic coil is energized, it generates suction, lifting the needle valve to open the injection hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist that facilitates complete combustion. 2. Fuel injector clogging: As one of the key components of an electronically controlled engine, the performance of the fuel injector significantly affects the engine's overall performance. Clogged fuel injectors can severely impair vehicle performance. The causes of clogging include carbon deposits from the engine accumulating on the injector or impurities in the fuel blocking the injector's pathways.
