What is the working principle of the fuel supply system?

Working principle of the diesel fuel supply system: The fuel transfer pump draws diesel from the fuel tank, filters out impurities through the filter, and then enters the low-pressure oil chamber of the fuel injection pump. After increasing the fuel pressure, it is delivered to the fuel injector through the high-pressure fuel pipe. When the fuel pressure reaches a certain value, the fuel injector sprays the fuel into the combustion chamber in a mist form, forming a combustible mixture that burns and performs work. The exhaust gases are then discharged into the atmosphere through the exhaust system. More details are as follows: 1. The task of the gasoline engine fuel supply system is to prepare a certain quantity and concentration of combustible mixture according to the requirements of various engine operating conditions, supply it into the cylinder, and ignite it near the end of compression for combustion and expansion to perform work. Finally, the supply system should also discharge the combustion exhaust gases into the atmosphere. 2. Components of the fuel supply system: fuel tank, fuel pipes, fuel pump, fuel filter, air filter, fuel pressure regulator, fuel injector, cold start injector, fuel pressure pulse damper, intake manifold, exhaust manifold, etc.
