1. Material of the injector nozzle

The material selection of the injector nozzle is crucial to its performance and durability. Common materials of injector nozzles include stainless steel, brass, aluminum alloy and ceramic.

Stainless steel injector nozzle: It has excellent corrosion resistance and high temperature strength, is not easily affected by the external environment, has low cost, and is widely used in vehicles such as automobiles and airplanes.

Brass injector nozzle: It is a copper alloy injector nozzle material with good wear resistance, thermal conductivity and machinability, and can effectively resist acid, alkali and corrosion. But its price is relatively high.

Aluminum alloy injector nozzle: It has the characteristics of low density, high thermal conductivity, electrical conductivity and low cost. Aluminum alloy injectors are suitable for high-speed diesel engines, which improves the combustion efficiency of the engine, reduces the weight of the engine, and reduces the fuel consumption rate.

Ceramic injector nozzle: It is a new type of injector nozzle material in the injector nozzle factory, with good wear resistance and high temperature stability, high hole opening accuracy, high injection accuracy, high efficiency and long service life. However, due to the high cost, the application is subject to certain restrictions.

2. Operation of the injector nozzle

The operation of the injector nozzle mainly involves the steps of cleaning, replacing and debugging the injector nozzle.

Cleaning the injector nozzle: The injector nozzle will accumulate a certain amount of carbon deposits and impurities during use, which will affect the injection effect. Therefore, the injector nozzle needs to be cleaned regularly. When cleaning, the injector nozzle needs to be removed from the engine first, and then the injector nozzle needs to be cleaned with a special cleaning agent or gasoline. When cleaning, be careful not to damage the nozzle hole and the pintle of the injector nozzle.

Replace the injector nozzle: When the injector nozzle is damaged or blocked, it needs to be replaced in time. When replacing the injector nozzle, it is necessary to select the injector nozzle that matches the engine model and the injection system, and ensure its quality and reliable performance. When replacing, it is necessary to follow the correct steps to avoid damaging other parts.

Debug the injector nozzle: After replacing or cleaning the injector nozzle, it needs to be debugged to ensure that the injection volume and injection atomization effect of the injector nozzle meet the requirements of the engine. During debugging, special debugging equipment can be used to detect and adjust the injector.
