Pressure wave damping type fuel system

The invention aims at providing a pressure wave damping type fuel system. The pressure wave damping type fuel system comprises a fuel tank, a voltage stabilizer and a fuel injector, wherein the fuel tank is connected with a filter, a fuel delivery pump and a high-pressure fuel pump sequentially and then connected with the voltage stabilizer, the voltage stabilizer is connected with the fuel injector and also directly communicated with the fuel tank through a fuel return pipe, a safety valve is installed on the fuel return pipe, the voltage stabilizer comprises a voltage stabilizer casing, a hole pipe is installed inside the voltage stabilizer casing, a damping outer cavity is formed between the voltage stabilizer casing and the hole pipe, a damping inner cavity is formed inside the hole pipe, damping holes of different sizes are formed in the hole pipe, and the damping outer cavity is connected with a load. By the aid of the pressure wave damping type fuel system, high-frequency pressure fluctuations and hydraulic shocks can be effectively weakened and absorbed, the fluctuation of the fuel injection quantity per cycle is reduced, the stability of the circulating fuel injection quantity of an engine is improved, the mutual influence of all cylinders of the engine is weakened, and the consistency of operation of all cylinders of the engine is improved.
