To achieve these goals, the technical solution used in the present invention is:
A kind of electric-controlled type vent systems of turbosupercharged engine, comprise pressurized machine, catalyst converter, gas exhaust manifold and exhaust gas by-pass valve, exhaust gas by-pass valve comprises interconnective waste gas valve, operating handle and bypass valve controller, the turbine end of pressurized machine comprises turbine chamber, exhaust gas entrance and waste gas outlet, exhaust gas entrance, turbine chamber are communicated with successively with waste gas outlet, form Pressure channel; And exhaust gas entrance is directly communicated with waste gas outlet, form pressure release passage, waste gas valve, between exhaust gas entrance and waste gas outlet, opens or closes described pressure release passage; Gas exhaust manifold comprises the first arm, the second arm, the 3rd arm and the 4th arm; Described bypass valve controller adopts electric actuator, and electric actuator is connected with ECU (Electrical Control Unit); The first described arm is connected with the 4th arm, and the second arm is connected with the 3rd arm, form the independent exhaust passage of two-way, and the outlet end of gas exhaust manifold is connected at the outlet end of gas exhaust manifold with the exhaust gas entrance of pressurized machine; Catalyst converter is connected with the waste gas outlet close coupling of pressurized machine.
Preferably, the close coupling position of the waste gas outlet of catalyst converter and pressurized machine is provided with fixture larynx hoop.
Owing to have employed technique scheme, the invention has the beneficial effects as follows:
The electric-controlled type vent systems of a kind of turbosupercharged engine of the present invention, gas exhaust manifold adopts air flue isolation technique, and waste gas can be discharged in time, can not interact between air flue, thus can not affect the power of motor; The waste gas valve of pressurized machine adopts electric actuator to control, also waste gas valve can be opened in time when engine cold-start, waste gas is directly discharged from the exhaust gas entrance of pressurized machine through waste gas outlet, can not through turbine chamber, path is shortened, exhaust energy loss is little, can catalytic reaction in time in catalyst converter; Meanwhile, adopt close coupling to be connected between catalyst converter with pressurized machine, eliminate transition tube, path is shortened further, and exhaust energy loss reduces further, and in catalyst converter, in time, the exhaust emission of discharge is less in reaction; Vent systems of the present invention, by the gas exhaust manifold that air flue is separated, the exhaust gas by-pass valve that electric actuator is formed and the catalyst converter that close coupling is connected combine, and can realize the timely discharge of waste gas and the shortening of exhaust path, the minimizing of exhaust energy loss, thus reduce environmental pollution.
