What is the function of a diesel fuel injection pump?
1 Answers
Diesel fuel injection pump functions: increasing fuel pressure, controlling injection timing, and regulating fuel injection quantity. The fuel injection pump is the 'heart' of a diesel engine, and it must be properly maintained. The fuel injection pump is a crucial component of automotive diesel engines, consisting of an integrated assembly that includes the fuel injection pump and governor. The governor ensures low-speed operation of the diesel engine and imposes a maximum speed limit, maintaining a specific relationship between injection quantity and engine speed. Fuel injection pumps are mainly categorized into three types: plunger-type fuel injection pumps, injector-type fuel pumps, and rotary distributor-type fuel injection pumps.
