The FSAE racing car air inflow system comprises a throttling valve assembly, an air inflow header pipe, a pressure stabilizing cavity, a plurality of air inflow manifolds, a high-pressure oil rail, an oil spraying base and an oil spraying nozzle. The two ends of the air inflow header pipe are connected with the throttling valve assembly and the pressure stabilizing cavity respectively. The air inflow manifolds are connected with the pressure stabilizing cavity at equal intervals. The oil spraying base is connected with the air inflow manifolds, and the oil spraying nozzle is connected with the oil spraying base and the high-pressure oil rail. The pressure stabilizing cavity is of a rotating body structure composed of a conical cylinder and a hemisphere. The large end of the conical cylinder is an open end, and the small end of the conical cylinder is a closed end provided with a sealing plate. The open end of the conical cylinder is in smooth transition connection with the open end of the hemisphere. A connector is formed in the sealing plate. The air inflow header pipe is inserted in an inner cavity of the pressure stabilizing cavity. The connector and the outer wall attaching portion of the air inflow header pipe are connected in a sealed mode. By means of the system, the air inflow performance of an engine can be remarkably improved, and full play is given to the capacity of the engine.
