The invention discloses a waste gas circulating valve cavity structure. The structure comprises a chassis; an air inlet passage is arranged inside the chassis; two connecting passages are arranged onone side of the air inlet passage; a cavity is arranged on one side of the connecting passages; one side of the cavity communicates with a placing tank via a fixed passage; a fixed block is fixed on the cavity; two discharge needles are arranged on the fixed block; two fixed tanks matched with the discharge needles are arranged on the inner wall of the cavity; a metal sheet is arranged on the inner wall of each fixed tank; a connecting groove is formed in the cavity; and a conductive rod is arranged in the connecting groove. The waste gas circulating valve cavity structure solves the problemsthat particle carbon deposits cannot be effectively removed by an existing waste gas circulating valve, particle carbon deposits which enter a motor cause plugging of the motor, and the practical service life of the motor is affected.
Description
technical field [0001] The invention relates to the technical field of exhaust gas circulation valves, in particular to an exhaust gas circulation valve chamber structure. Background technique [0002] The exhaust gas recirculation valve can increase the intake air volume accordingly. The increase of the EGR rate can reduce the throttling loss of the gasoline engine under low and medium load conditions, and reduce the fuel consumption rate of the gasoline engine. The exhaust gas contains a large amount of carbon particles, and the existing exhaust gas The circulation valve cannot effectively remove the carbon deposit particles, and the carbon deposit particles enter the engine and cause engine blockage, which affects the practical life of the engine. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an exhaust gas recirculation valve chamber structure, which solves the prob...
