Description
Technical field
The utility model relates to technical field of engines, more particularly to a kind of air inlet recycling valve seat, have the air inlet
Recycle the inlet manifold and engine of valve seat.
Background technique
With the progress and the improvement of people's living standards of science and technology, automobile has progressed into vast people's lives
In, give providing a great convenience property of people.And gradually popularizing with automobile, people are not only more next to the requirement of automotive performance
It is higher, vehicle ride comfort is required also higher and higher.
When suddenly slowing down, engine air throttle aperture strongly reduces engine with supercharger, but due to the inertia of supercharger impeller,
Booster can still continue to be pressurized, so that the pressure between booster and air throttle in pipeline sharply increases, at this time to prevent from being pressurized
Device surge needs in time to release the pressure between booster and air throttle in pipeline, and engine with supercharger needs to design air inlet thus
Pressure relief system prevents turbocharger surge.Air inlet pressure relief system, which refers to, manages after pipeline and compressor before connection supercharger air compressor
Loine pressure after compressor is let out the pressure relief system to compressor when needed by road, recycles valve seat (CRV by air inlet
Valve) control pressure release whether.
Currently, generally CRV valve being mounted on booster pressure shell or being mounted on the inter cooling pipeline after compressor.Work as CRV
When valve is mounted on booster pressure shell, current by pass is integrated in inside booster, and when CRV valve opening carries out discouraged, lose heart gas
Before stream is directly back to compressor impeller, it is mixed to form powerful turbulent flow with charge air flow before compressor impeller, is caused biggish
Lose heart noise.Noise is passed to vehicle internal influence to vehicle noise qualities and NVH performance, reduces comfort.When CRV valve is installed
When on inter cooling pipeline, CRV valve installs valve seat and inter cooling pipeline is integrally welded, and is connected to inter cooling pipeline, and current by pass is logical
Welding structure sealing is crossed, but since inter cooling pipeline is suspended from engine, engine easily causes CRV valve to install valve seat when running
Place generates resonance, and the welding position that being used for a long time may cause between CRV valve installation valve seat and inter cooling pipeline generates crack, thus
So that seal failure, engine charge deficit power is reduced, and the more serious engine that may cause is unable to operate normally, and influences vehicle
Traveling in dynamic property and safety.
