High Quality Diesel Injector 0 445 110 254 0445110254 Diesel Fuel Injector Spare Part

Working principle:
1.Pressure transmission: The diesel fuel injector obtains fuel through a high-pressure fuel supply system (such as a high-pressure common rail system) and transmits its pressure to the injector.

2.Injection timing control: The injector injects fuel into the combustion chamber of each cylinder at an accurate time according to the control signal of the engine.

3.Spray formation: Through the nozzle of the injector, the high-pressure fuel is atomized into tiny particles so that it can be better mixed with air and promote combustion.

4.Fuel quantity control: The injector controls the injection quantity by controlling the injection pressure and the size of the nozzle to adapt to the engine's workload and speed.

Construction:
1.Nozzle body: Usually made of metal alloy, it has the characteristics of corrosion resistance and high temperature to withstand the action of high-pressure fuel.

2.Nozzle hole: Located at the end of the nozzle body, it is responsible for injecting high-pressure fuel into the combustion chamber. The diameter and number of the nozzle holes affect the characteristics of the fuel spray.

3.Nozzle tip: Usually made of metal alloy, it is used to support and position the nozzle hole and ensure the accuracy and stability of fuel injection.

4.Control valve: controls the entry and injection of fuel, usually controlled by a solenoid valve or a pressure control valve to ensure the accuracy and timing of injection.

5.Sealing device: provides a seal between the injector and engine components to prevent fuel leakage and ensure normal injection operation.

The working principle and structure of the diesel engine injector is a complex and sophisticated system, which directly affects the engine's fuel injection control and combustion efficiency.
