5.7 Fuel system and regulation

The fuel adjustment system and speed is the most important operative part of
the diesel engine, it includes fuel feed pump, diesel filter, fuel injection pump,
regulator, high-low pressure piping, etc., see Figure 10 for details.

2 Fuel injection pipe
3 Injector
4 Injection pump
The fuel feed pump is responsible for transporting the fuel to the fuel filter, go
through it and then drive it to the injection pump. The fuel generates high
pressure in the injection pump, then it is sprayed into the combustion chamber
through the injector, due to high pressure generated in the combustion chamber
an explosion that burns fuel occurs and displaces the piston and the engine
rotates.
The fuel transportation pump is a single fuel pump with a single piston. It is
installed on the outer side of the oil injection pump and is driven by the eccentric
gear of the shaft pump of fuel injection.
