About the product

The working principle of the injector rocker arm for diesel engine parts mainly includes the following key parts:

The structural components: The fuel injector rocker arm mainly consists of the rocker arm, rocker shaft, push rod and fuel injector, etc. The rocker arm is connected to the fuel injector through the rocker shaft, while the push rod connects the rocker arm and the fuel injection pump, achieving the control of fuel injection.

Working principle: When the diesel engine is in operation, the rotation of the camshaft drives the rocker shaft to rotate, which in turn causes the rocker to move up and down. The rocker transmits the motion to the injector through the push rod, opening and closing the needle valve inside the injector. Specifically, when the cam on the camshaft pushes the rocker upward, the push rod also rises accordingly, causing the needle valve inside the injector to open, and high-pressure diesel is injected into the combustion chamber through the nozzle; when the cam on the camshaft descends, the rocker and the push rod also descend, and the needle valve inside the injector closes, stopping the fuel injection.

The functions of key components:

Camshaft: Drives the rocker shaft and rocker arms through the up-and-down movement of its cams.
Pushrod: Connects the rocker arm and the fuel injector, transmitting motion.
Fuel injector: Contains components such as a needle valve and nozzle, achieving precise fuel injection.

Technical parameters and maintenance: The technical parameters of fuel injectors include injection pressure, injection volume, and injection angle, etc. These parameters directly affect the performance and fuel economy of the engine. In terms of maintenance, it is necessary to regularly check the sealing and injection pressure of the fuel injectors to ensure their normal operation.
