Fuel supply system of multi-fuel injection pump diesel engine, diesel engine and vehicle

The utility model belongs to the technical field of internal combustion engine control, and particularly relates to a fuel supply system of a multi-fuel-injection-pump diesel engine, the diesel engine and a vehicle. The fuel supply system of the multi-fuel-injection-pump diesel engine comprises a fuel tank, a fuel injection pump set and a fuel injector set. The fuel injection pump set comprises at least two fuel injection pumps which are arranged at the output end of the fuel tank in parallel. The fuel injector set is arranged at the output end of the fuel injection pump set. According to the fuel supply system of the diesel engine with the multiple fuel injection pumps, the fuel injection pumps are arranged at the output end of the fuel tank, the maximum fuel supply capacity required by the engine can be met, the performance of the engine can be fully played, and the requirement for follow-up engine development is met. Meanwhile, the multiple fuel injection pumps are arranged in parallel, so that the fuel su
