High Quality Diesel injector 4062569 Diesel Fuel Injector for QSX15 ISX15 Spare Part

The fuel injector is a key component in the fuel injection system of a diesel engine. It can be divided into several main types according to its structure and working principle:

1.Unidirectional fuel injector (single-hole fuel injector): Unidirectional fuel injector is one of the most basic types of fuel injectors, usually containing one or more fixed-diameter spray holes, through which high-pressure fuel is sprayed into the engine combustion chamber. This type of fuel injector has a simple structure and is widely used, but usually has limited control over the timing and amount of fuel injection.

2.Multi-directional fuel injector (multi-hole fuel injector): Multi-directional fuel injector has multiple spray holes, usually arranged in a ring or linear pattern around the fuel injector. This type of fuel injector can achieve a more uniform fuel injection distribution and improve engine combustion efficiency and performance.

3.Spray cone angle adjustment fuel injector: This type of fuel injector can adjust the spray angle and shape of the spray to meet the combustion requirements under different workloads and operating conditions. By adjusting the structure or control system of the fuel injector, the spray cone angle can be changed to optimize the combustion process.

4.High-pressure common rail injectors: High-pressure common rail injectors are an advanced type of injectors in modern diesel engine fuel injection systems. They are characterized by providing a continuous and stable high-pressure fuel supply through the high-pressure common rail system to achieve more precise and flexible fuel injection control. This type of injector usually has a higher injection pressure and more precise injection control capabilities, which can achieve more efficient combustion and emission control.
