Technical field
The utility model belongs to technical field of automobile engine, relates to a kind of air inlet reflux of turbocharger of motor.
Background technique
Turbosupercharger is actually a kind of air compressor, increases air inflow by pressurized air, is the constituent element of engine controlling unit.
Existing engine controlling unit, such as Chinese patent literature data discloses engine controlling unit [application number: 201310300811.9, application publication number: CN103541822A], it comprises pressure-increasing machine, air inflow modulating valve and exhaust gas recirculation device, between the inlet air pathway of pressure-increasing machine setting and motor and exhaust passageway, raise for making the pressure of the air inlet in inlet air pathway, pressure-increasing machine comprises the compressor be configured with inlet air pathway, be configured in turbo machine and the running shaft of exhaust passageway, exhaust gas recirculation device comprises exhaust gas recirculation path and exhaust gas reflux valve, exhaust gas recirculation path makes the part the exhaust of discharging from the firing chamber of motor to exhaust passageway flow to inlet air pathway, the backflow of the most backward firing chamber, exhaust gas reflux valve is for regulating the exhaust gas recirculation in exhaust gas recirculation path, the entrance of exhaust gas recirculation path is connected with the exhaust passageway more further downstream than turbo machine, the outlet of exhaust gas recirculation path is connected with the inlet air pathway than compressor more upstream.
The engine controlling unit of this kind of structure, air inlet reflux is not set between the entrance pipe of swimming on the compressor and the export pipeline in downstream, when vehicle is shut down, air throttle is closed, compressor also can work on some time, cause partial air to be compressed in export pipeline cannot discharge, very large to the impact force of air throttle, very large noise can be sent when vehicle is shut down; Due to the central axis of exhaust passageway and the central axis of exhaust gas recirculation path perpendicular, exhaust gas recirculation path is arranged in the horizontal direction, and the ponding produced in exhaust gas recirculation path can not be discharged, and reduces working life of exhaust gas reflux valve.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and provide a kind of air inlet reflux of turbocharger of motor, this device is arranged in inlet air pathway, solves the noise how reduced when vehicle is shut down.
The purpose of this utility model realizes by following technical proposal: a kind of air inlet reflux of turbocharger of motor, described turbosupercharger is located between the inlet air pathway of motor and exhaust passageway, it is characterized in that, described air inlet reflux comprises air inlet current return circuit and reflux valve, described reflux valve is positioned at air inlet current return circuit place, the export pipeline that import and the inlet air pathway of described air inlet current return circuit are positioned at turbosupercharger downstream is connected, the entrance pipe that outlet and the inlet air pathway of described air inlet current return circuit are positioned at turbosupercharger upstream is connected, along air inlet flow direction described in angle between the longitudinal center line of air inlet current return circuit import and the longitudinal center line of export pipeline be acute angle.
During automobile normal running, reflux valve blocks air inlet current return circuit, air is along entrance pipe, turbosupercharger, export pipeline and air throttle move, when automobile is shut down, reflux valve is opened, make air inlet current return circuit and entrance pipe, export pipeline is all connected, the import of air inlet meeting along air inlet current return circuit of export pipeline is now entered into by turbosupercharger, the passage of air inlet current return circuit and the outlet return of air inlet current return circuit are to entrance pipe place, when vehicle is shut down, the impact force of air to air throttle is little, reduce noise, and the angle between the longitudinal center line and the longitudinal center line of export pipeline of the flow direction air inlet current return circuit import of air inlet is acute angle, namely the import of air inlet current return circuit is obliquely installed relative to export pipeline, make air inlet can enter into air inlet current return circuit smoothly gently, fluency when air inlet is refluxed is good, uniformity is good, simultaneously because air inlet current return circuit is obliquely installed relative to substantially horizontal, even if there is part water to enter into air inlet current return circuit along with air inlet, also can flow away from air inlet current return circuit toward dirty due to water, reflux valve place is made to produce ponding, reflux valve long service life.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, described acute angle is between 70-85 degree.This kind of angle is set, make air inlet can enter into air inlet current return circuit more smoothly, make air inlet can not excessively turn in air inlet current return circuit simultaneously, make air inlet in air inlet current return circuit can smooth, flow along air inlet current return circuit uniformly, reduce the impact force of air inlet, reduce noise.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, the circular in cross-section of described air inlet current return circuit import.This kind of structure, makes air inlet flow to air inlet current return circuit from export pipeline more smoothly.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, the cross section of described air inlet current return circuit outlet is flat.This kind of structure, the wind-force that air inlet current return circuit is exported is stronger, and blocks air enters into turbosupercharger.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, the inlet of described air inlet current return circuit has ring-shaped valve seats, and the spool of described ring-shaped valve seats and reflux valve matches.When spool is resisted against on ring-shaped valve seats, i.e. the import of the airtight air inlet current return circuit of spool, reflux valve makes air inlet current return circuit cut out, and air inlet can not enter into air inlet current return circuit, and this kind of state of reflux valve is the state of automobile normal running.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, described reflux valve is connected in the sidepiece of air inlet current return circuit by bolt.Fixing mechanism is simple, and is positioned at sidepiece, conveniently keeps in repair reflux valve, changes.
In the air inlet reflux of above-mentioned a kind of turbocharger of motor, described reflux valve is electronic reflux valve.Automaticity is high, and the transfer speed controlling air inlet current return circuit break-make is fast.
Compared with prior art, the air inlet reflux of the turbocharger of motor that the utility model provides, along the flow direction of air inlet, angle between the longitudinal center line of the longitudinal center line of air inlet current return circuit import and the export pipeline of inlet air pathway is acute angle, between 70-85 degree, when automobile is shut down, reflux valve is opened, when making air inlet enter into air inlet current return circuit from the export pipeline of inlet air pathway, flowing is smooth and easy gently, the fluency that air inlet is flowed in air inlet current return circuit is good, uniformity is good, reduce the impact force of air inlet, reduce stopping noises, simultaneously because air inlet current return circuit is obliquely installed, make can not produce ponding in air inlet current return circuit, electronic reflux valve long service life.
