Komatsu Excavator Parts PC400-8 Common Rail

About the product:

Komatsu PC400-8 is a common excavator model that uses a common rail fuel system to achieve fuel injection control. The following are some common components of the common rail accessories of the PC400-8 excavator:

1. High-pressure common rail: The high-pressure common rail of the PC400-8 excavator is a high-pressure metal pipe system that is responsible for supplying fuel to the fuel injectors. The high-pressure common rail can provide stable high-pressure fuel and ensure accurate fuel injection control during the injection process.
2. Pressure sensor: The fuel system of the PC400-8 excavator is equipped with a pressure sensor to monitor the fuel pressure in the high-pressure common rail. The sensor feeds back the fuel pressure information to the engine control unit (ECU) for accurate fuel injection adjustment and control.
3. Fuel injector: The fuel injector of the PC400-8 excavator is responsible for injecting high-pressure fuel into the combustion chamber of the engine. The design of the fuel injector and the control of the injection amount are crucial to the combustion efficiency and power output of the engine. High-quality fuel injectors can ensure the accuracy and stability of fuel injection.
4. Fuel filter: The fuel filter is used to filter impurities and pollutants in the fuel to ensure the cleanliness of the fuel. In the common rail system of the PC400-8 excavator, the fuel filter can prevent impurities from entering the high-pressure common rail and the fuel injector, improving the reliability and life of the system.
5. Fuel pump: The fuel pump of the PC400-8 excavator is responsible for extracting fuel from the fuel tank and providing sufficient pressure to send it to the high-pressure common rail. The performance of the fuel pump directly affects the working stability and fuel supply capacity of the fuel injection system.
