The main types of diesel fuel injectors

Diesel engines have the characteristics of high thermal efficiency, good economy, less failure and less exhaust pollution. Therefore, diesel engines are mostly installed in large agricultural machinery equipment (such as tractors, combine harvesters, etc.). In recent years, as the shortcomings of low speed, high quality, and high manufacturing and maintenance costs of diesel engines have been overcome, the scope of application has continued to expand.
The diesel injector is directly installed on the cylinder head of the diesel engine, and the head of the injector is in contact with the high-temperature combustion chamber. Its working conditions are very harsh, so it is one of the key components that affects the design index and performance of the diesel engine. Injectors are generally divided into two types and closed type. The vast majority of automotive diesel engines use closed injectors, and there are three common forms: hole injectors, pin injectors and low inertia injectors.
