The Fuel Injection Pump Is An Important Component Of Automotive Diesel Engines
The fuel injection pump is an important component of the automotive diesel engine. The fuel injection pump assembly is usually composed of components such as the fuel injection pump and speed controller installed together as a whole. Among them, the governor is a component that can guarantee the low-speed operation of the diesel engine and limit the maximum speed, and ensure that there is a certain relationship between the injection amount and the speed. The fuel injection pump is the most important component of a diesel engine, regarded as the "heart" component of a diesel engine. Once it malfunctions, it can cause the entire diesel engine to malfunction.
The fuel injection pump can be mainly divided into three types: plunger type fuel injection pump, fuel injection pump injector, and rotor distribution type fuel injection pump. Among them, the plunger type fuel injection pump is the oldest and most widely used, with high reliability; Fuel injection pump - The fuel injector integrates the two and is directly installed on the engine cylinder head, which can eliminate the adverse effects caused by high-pressure fuel pipes (requiring an additional driving mechanism on the engine); The rotary distribution fuel injection pump only has one pair of pistons, mainly relying on the rotation of the rotor to achieve fuel pressurization and distribution. It has the characteristics of small volume, light weight, convenient use, and low cost.
In China, fuel injection pumps are based on plunger stroke, pump cylinder center distance, and structural type, and are equipped with different sizes of plungers to form several types of fuel injection pumps with varying fuel supply in one working cycle, forming series I, II, III, A, B, P, and Z to meet the needs of various diesel engines.
