Description
Technical field
The present invention relates to a kind of exhaust gas turbocharge auxiliary device, the automobile (using diesel oil or petrolic automobile) applying this device and the method reducing turbine time lag, it is possible to reduce turbine time-lag effect.
Background technology
At present, along with the environmental consciousness of people strengthens, fuel-economizing and the strong electromotor of power is becoming increasingly popular, small displacement exhaust gas turbocharge electromotor becomes the main equipment on automobile now.nullBut waste gas exhaust-driven turbo-charger exhaust-gas turbo charger has time-lag effect，Owing to the pressurization of exhaust-driven turbo-charger exhaust-gas turbo charger is mainly produced by the air inlet turbine being positioned in air intake duct，And air inlet turbine is driven by the exhaust driven gas turbine being positioned in exhaust duct，The rotating speed of exhaust driven gas turbine is determined by engine back pressure，When driver steps on suddenly throttle acceleration，Owing to now engine back pressure will not increase immediately，Secondary speed in exhaust-driven turbo-charger exhaust-gas turbo charger does not catches up with step and makes the pressure of supercharging not increase immediately，The power of electromotor can not be linearly increasing along with the action of gas pedal，Its real process is for after driver steps on gas pedal suddenly，Higher pressure at expulsion is produced after entering gas in-cylinder combustion along with more air with fuel oil，This pressure at expulsion drives exhaust driven gas turbine to accelerate，Owing to entering、Exhaust driven gas turbine is fixing to be connected，Air inlet turbine sync plus white，So that the boost pressure of air inlet raises，This process produces longer time delay，The generally 5-8 second；On the other hand, when driver loosens suddenly (including being totally released) throttle, owing to the rotating speed of inlet and outlet turbine will not slow down immediately along with loosening of gas pedal, admission pressure and air inflow in the air inlet pipe of rear portion will not decline immediately so that the power of electromotor will not weaken immediately along with the loosening up of gas pedal.
nullBefore existing exhaust-driven turbo-charger exhaust-gas turbo charger is generally positioned at air throttle，When the unexpected close the throttle of driver、The aperture of air throttle can synchronize to diminish，If being totally released gas pedal, the aperture of air throttle can become minimum，Now electromotor can be in idling state，The power of the front engine of throttle opening reduction is stronger，Enter、The rotating speed of exhaust driven gas turbine is higher，Rotator inertia yet with turbine，After the aperture of air throttle diminishes suddenly，The rotating speed of air inlet turbine will not reduce rapidly，The pumping action of air inlet turbine will not weaken rapidly，Owing to the aperture of air throttle diminishes，Gas resistance when by air throttle increases，Thus the air pressure in the rear portion air inlet pipe between exhaust-driven turbo-charger exhaust-gas turbo charger and air throttle can raise rapidly，If the aperture of air throttle diminishes suddenly to idling mode, can be owing to too high air pressure damages air throttle component or causes pipeline to leak gas.In prior art; it is generally fitted with turbocharger relief valve; its function is when the air pressure in the air inlet pipe of above-mentioned rear portion exceedes the setting value of relief valve; air in above-mentioned pipeline is entered the external world; thus protect air throttle or pipeline, but the gas with certain pressure that this part is discharged into the external world is not fully utilized.
