Fuel injection pump working principle-1

1.Fuel injection pump working principle-introduction The fuel injection pump is an important part of the diesel engine. The crankshaft gear of the engine drives the camshaft to rotate to complete the fuel injection function. The fuel pump is usually equipped with a governor to ensure the low speed operation of the diesel engine and the […]

How The Common Rail Works In The Engine?

Electronically controlled fuel injection technology directly or indirectly forms a constant high-pressure fuel through a common rail, distributed to each injector, and opened and closed by means of a high-speed electromagnetic on-off valve integrated on each injector, timing, The amount of fuel injected into the combustion chamber of the diesel engine is controlled in a […]
