Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of petrol engine turbosupercharger Decompression valves, the invention still further relates to the system that a kind of this valve is used for the recirculation of petrol engine turbosupercharger.
Background technique
At present, turbosupercharged engine is when being in anxious deceleration regime, closure is near full cut-off or close fully, and supercharger rotor is because inertia continues supercharging, in the air inlet pipeline of pressurized machine, produce and continue elevated pressure, this moment, flow reduced and not decline in time of rotating speed, easily caused the surge of motor, and adopt Decompression valves to open valve this moment.Solenoid valve input end in the control gear of traditional Decompression valves is an intake manifold, and when access failure solenoid valve the other end vacuum source, the faint valve of opening caused induction noise because the closed throttle intake manifold vacuum increases when caused engine retard this moment; When slowing down the back speed-raising, because closure is opened, the intake manifold internal pressure raises, but in time do not reach the requirement of closing Decompression valves, it is slow to close response, also causes that induction noise and time for acceleration are longer, and vehicle comfort and acceleration responsiveness have obvious decline.Chinese patent application 200610100047.0 discloses a kind of system and method that is used to operate turbosupercharged engine.This system comprises motor, turbosupercharger, pressurized air is supplied to intake manifold, is used for burning in cylinder combustion.Turbine is connected to gas exhaust manifold, so that exhausting air expands by turbine, merit is offered the turbo-charger shaft of the turbine additional issue device that is connected to compressor, and then rotates the turbo-charger shaft of this turbine additional issue device.Owing to the compression of compressor causes air temperature to be increased, compressor extracts surrounding atmosphere and passes filter, and pressurized air is offered heat exchanger, so that reduced the temperature of air before pipe is attacked in the air inlet that is conveyed into motor.Recirculation (egr) valve is configured to recirculation and passes the desirable throughput that compressor enters from heat exchanger in the back.In addition, can be from the ideal engine air displacement of gas exhaust manifold via exhaust pressure relief valve bypass turbine.Power unit also comprises controller.Its deficiency is a complex structure, does not also solve to produce in the air inlet pipeline when being in anxious deceleration regime to continue elevated pressure.
Summary of the invention
The object of the invention provides a kind of valve, and this valve not only opens and closes rapidly, and simple in structure.
Another object of the present invention provides the system that a kind of this valve is used for the recirculation of petrol engine turbosupercharger.When motor is in anxious deceleration regime, closure is near full cut-off or close fully, in the air inlet pipeline of pressurized machine, produce and continue elevated pressure, adopt this moment this system control Decompression valves to open and close valve rapidly, reduce because valve opening shifts to an earlier date and closes the slow induction noise that causes; Closure wishes that again pressurized machine can rise to working speed as early as possible after opening, and improves the booster response performance.
Technological scheme of the present invention is: a kind of valve, comprise valve body and electric wiring base, and threeway is arranged on the valve body, be respectively first interface, second interface and the 3rd interface; It is characterized in that: also have slidably slide block of the electromagnetic activation of passing through in the described valve body between first interface and the 3rd interface, slide block one end connects spring, and slide block still is the spool of second interface, controls the aperture of second interface.
A kind of petrol engine turbosupercharger recirculating system that adopts above-mentioned valve, the ECU (Electrical Control Unit) (ECU) that comprises motor and control engine operation, the waste gas that air exports by air-strainer and turbosupercharger recirculation are mixed and are entered engine intake manifold by flexible pipe before the closure and closure; Enmgine exhaust connects turbocharger inlet, and the turbosupercharger exhaust outlet connects three-element catalytic; Turbosupercharger recirculation outlet also connects Decompression valves, the work of valve control Decompression valves, and ECU is electrically connected pressure transducer, throttle valve body position transducer and valve.It is characterized in that: described valve is a three-way magnetic valve, and valve first interface connects vacuum tank, and second interface connects Decompression valves, and the 3rd interface connects the preceding flexible pipe of closure.
The working principle of this system: open condition according to Decompression valves; The pressure reduction before and after the closure and the variance ratio of throttle valve body surpass setting value, in case satisfy setting value condition, valve open; Otherwise Decompression valves is in closed condition.When the motor proper functioning, be in closed condition under the positive pressure of solenoid valve before closure; When engine retard, closure produces lasting elevated pressure near closing in the air inlet pipeline of turbosupercharger, and ECU output signal control electromagnetic valve is connected vacuum tank one end interface, opens Decompression valves under vacuum force rapidly; When motor recovers proper functioning, the positive pressure following moment of Decompression valves valve before initial tension of spring and closure closes, and solved faintly to open with the slow pressurized machine induction noise problem that causes of valve closing and responsiveness when quickening owing to Decompression valves shifts to an earlier date.
Good effect of the present invention: native system is owing to only adopt a threeway vacuum solenoid control opening and closing Decompression valves, and the slide block in the solenoid valve is shifted on one side, connects vacuum tank; When shifting to another side, connect the preceding pressure (or middle cooling pipe road) of closure.Prevent slow down the suddenly induction noise that causes and rise to working speed when quickening as early as possible of motor.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
