The following describes the functions of the fuel supply system: The fuel supply system can 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 products, i.e., exhaust gases, into the atmosphere.
