Description
Technical field
The utility model relates to the parts of vehicle, is specifically related to a kind of air filter air inlet pipe assembly and air filter assembly.
Background technique
Along with the development of automotive industry, people require more and more higher to the power character, Economy, NVH etc. of automobile.Supercharging technology is one of major measure improving engine power performance and economic performance, and most widely used be turbocharging technology.Turbosupercharged engine is when the unexpected accelerator releasing of anxious acceleration, supercharger air compressor exports to the cavity being formed suddenly between closure and close, and pressurized air is still input in closed cavity due to inertia by gas compressor, after making supercharger air compressor, gas pressure is excessive, pressurized machine generation surge, produce surge noise, cause pressurized machine job insecurity, shake, even damage pressurized machine.
In order to avoid pressurized machine generation surge even damages pressurized machine; supercharged engine devises decompression protection system, and when the unexpected accelerator releasing of anxious acceleration, electronic control pressure release valve is opened by ECU; before gas after gas compressor is discharged into gas compressor by system of losing heart, after avoiding supercharger air compressor, pressure is excessive.But during pressure release, a kind of significantly pneumatic noise i.e. disappointing noise can be produced, the noise that loses heart propagates in air filter steam outlet pipe by gas compressor, propagate in air filter assembly through air filter steam outlet pipe, air filter assembly propagates into again in air filter air inlet pipe afterwards, in propagation process, partial noise is lowered or eliminates (mainly low frequency noise), but the noise that loses heart is the Kuanping Terrane of intermediate frequency and high frequency, be not easy to be lowered or to eliminate, and the suction port of air filter air inlet pipe is close to operator cabin distance, large to noise effect in car, the obvious identification of energy out, affect car load sound quality, do not accepted by client.
To lose heart noise problem to solve pressurized machine, in existing design, conventional measure has three kinds:
Scheme one, the system that to be lost heart by the pressurized machine of integrated form are that split external loses heart system.Split external loses heart, and system needs are independent designs Decompression valves fitting seat, support, Decompression valves suction tude, Decompression valves steam outlet pipe, pressurized gas after gas compressor are through Decompression valves suction tude, enter Decompression valves, then enter Decompression valves steam outlet pipe, before finally entering gas compressor.Split type disappointing system is by increasing the length of the pipeline that loses heart, and increase disappointing time and disappointing volume reduce the noise that loses heart, the system but split external loses heart, and occupy space large, difficult arrangement, cost is high.
Scheme two, air filter air inlet pipe adopt establishment pipe, and establishment pipe can reduce intermediate frequency noise and high frequency noise, but establishment pipe requires the straightway with certain length, and occupy space large, cost is high.
Scheme three, adjustment engine electric spray strategy, change turbocharger surge line, thus reduce supercharger ratio, reduce the flow that loses heart, reduce the noise that loses heart.But reduce pressure ratio and can reduce charging efficiency, reduce engine power and moment of torsion, have a strong impact on engine performance performance.
To sum up, in existing design, it is large that scheme one and scheme two occupy space, difficult arrangement, and cost is high, and the component affecting whole engine compartment are arranged, scheme implementation difficulty; Scheme three reduces charging efficiency, reduce engine power and moment of torsion, have lost engine power performance, and the frequency noise that scheme one, scheme two, scheme three can reduce or eliminate is limited in scope, the noise of some particular frequency range is reduced or eradicating efficacy not obvious.
