Fuel Injector Plunger And Bushing

Fuel Injector Plunger and Bushing are components of the Engine Fuel System in non-aircraft engines. They are part of the supply class Engine Fuel System Components, Nonaircraft, which falls under the supply group Engine Accessories.

The Fuel Injector Plunger is a cylindrical component that moves up and down within the fuel injector body. It is responsible for controlling the amount of fuel that is injected into the engine cylinders. The plunger is typically made of high-quality materials such as steel or stainless steel to withstand the high pressures and temperatures within the fuel system.

The Bushing, on the other hand, is a cylindrical sleeve that provides support and guidance for the plunger. It is usually made of a durable material such as bronze or brass to reduce friction and wear between the plunger and the injector body. The bushing ensures smooth movement of the plunger and helps maintain the proper fuel injection timing and accuracy.

Both the Fuel Injector Plunger and Bushing are critical components of the engine fuel system, as they play a crucial role in delivering the right amount of fuel to the engine cylinders for efficient combustion.
