First pressure-increasing machine level 16 comprises low-pressure air entrance 22, described low-pressure air entrance be suitable for purifying air filter 24 fluid entering air and be communicated with.Pressure-increasing machine level 16 also comprises pressure-increasing machine housing 26 and supply high-pressure air outlet 28.Then the pressurized air exported from pressure-increasing machine housing 26 flows to air/air heat exchanger 29, so that cooled before entering motor 12.
Turbine level 18 comprises turbine housing 30, described turbine housing motor 12 produce and by exhaust collector 36 collect exhausting air entrance 32 and outlet 34 between.In the outlet port of turbine housing 30, exhausting air is guided through catalyst converter and particulate filter 38 so that decontamination.
Temperature near the turbine housing 30 of turbine booster 14 is very high.Knownly by heat screen 40, the wall of turbine housing and surrounding environment to be separated.Heat screen 40 is substantially fixed on turbine housing 30 or is fixed on abutment.
But, in the region near turbine housing 30, there is pressurized air acoustical attenuators 42 usually.The function of this pressurized air acoustical attenuators 42 reduces " exhaust port noise " (bruits de bouche) (i.e. suction noise) of turbine booster 14.Known pressurized air acoustical attenuators 42 is made of plastic.In this case, pressurized air acoustical attenuators 42 needs to keep at a distance with the thermal region of turbine booster, to avoid being damaged by turbine booster 14 liberated heat.Then be the compactedness to cluster engine, the disadvantageous larger local volume of the compactedness especially on height, this plays restriction to the shape of front engine cover of the motor vehicle it being equipped with cluster engine.Two lines 44,46 of Fig. 2 illustrate the expectation restriction on cluster engine height, and this is especially in order to provide the innovation profile of front engine cover.
Should be appreciated that turbine booster 14 can be assembled place lower on the engine.But this solution cost is very high, because this needs again to limit cluster engine 10, the particularly total of motor 12.
Summary of the invention
Therefore the invention provides a kind of acoustic attenuation device for making the pressurized air of turbine boosting internal combustion engine circulate, it is characterized in that, described acoustic attenuation device comprises part, and described part is applicable to form the heat screen around one of them part of the turbine booster of turbine supercharged engine.
According to a modification, acoustic attenuation device comprises the acoustical attenuators be connected with the part forming heat screen, and described acoustical attenuators preferably forms single-piece with the part of described formation heat screen.
According to a modification, acoustical attenuators is selected from resonator, airborne noise reflector, airborne noise adsorber and adsorber with holes.
According to a modification, acoustical attenuators is helmholtz resonator.
According to a modification, the part forming heat screen is that metal is made, and especially corrosion resistant plate is made.
The invention still further relates to a kind of cluster engine, it comprises turbine boosting internal combustion engine and the pressurized air acoustic attenuation device according to above combination in any.
According to a modification, acoustic attenuation device is suitable for the noise of the exhausting air in the turbine downstream reducing turbine booster.
According to a modification, acoustic attenuation device is fixed on the housing of the turbine of turbine booster.
According to a modification, the part forming heat screen surrounds the housing of the turbine of turbine booster at least partially.
The invention still further relates to a kind of motor vehicle comprising cluster engine according to above combination in any.
Accompanying drawing explanation
By reading below with reference to accompanying drawing and the only detailed description to the embodiment of the present invention exemplarily, other features and advantages of the present invention will clearly, appended accompanying drawing wherein:
-Fig. 1 and 2 is the schematic diagram of known engine group;
-Fig. 3 and 4 is schematic diagram of cluster engine; And
-Fig. 5 is the detailed view of Fig. 4.
Embodiment
In figures 3 and 4, identical with the element in Fig. 1 and 2 element adopts identical reference character.Needs for the sake of simplicity, these elements are not described again.
With the difference of the cluster engine 10 of Fig. 1 and 2, the cluster engine 100 of Fig. 3 and 4 is that cluster engine 100 comprises acoustic attenuation device 102, circulate for making the pressurized air of turbine boosting internal combustion engine, described turbine boosting internal combustion engine comprises part 104, and described part is suitable for forming the heat screen at least partially around the turbine booster 14 of turbine supercharged engine 12.In this case, by surrounding a part for turbine housing 30, part 104 forms the heat screen of this part of the turbine housing 30 around turbine booster 14.
It can also reduce different part close degree each other in known manner and follow below the front engine cover of motor vehicle can the design restriction 46 limited to of line height.
Acoustic attenuation device 102 is fixed on the turbine housing 30 of cluster engine 100 in this case, and this can by any suitable fixed equipment, such as screw.Should be appreciated that acoustic attenuation device 102 can also be fixed on other parts of described cluster engine according to the structure of cluster engine 100.
In this case, acoustic attenuation device 102 comprises the acoustical attenuators 106 be connected with the part 104 forming heat screen, and described acoustical attenuators preferably forms single-piece with part 104.
