Description
Technical field
The present invention relates to the hose assembly technical field, particularly a kind of pipeline assembly technology with turbosupercharging automobile crane box ventilation system.
Background technique
The waste gas that produces in the cylinder in the engine operation process gets into crankcase through piston ring; Be mixed into gas blowby (containing a large amount of atomizing machine oil, water vapour, carbon dioxide, hydrocarbon, sulphide or the like) with the machine oil that splashes in the crankcase; Gas blowby can cause that machine oil is rotten, oil sealing corrosion etc.; The effect of the crankcase ventilation system of motor is the gas handling system that gas blowby is exported to motor, is burnt once more.
Normal suction automobile crane case air pipeline mainly is made up of a pipeline that has one-way valve; Gas blowby imports intake manifold by crankcase bleed pipe and gets into next burn cycle; This loop direction is controlled by one-way valve, and the fuel-air mixture that does not allow to have neither part nor lot in burning in the intake manifold gets into crankcase.Because the force value in the intake manifold is normal pressure or negative pressure; Pressure in the crankcase is because the entering of waste gas is always small malleation; So the weighing apparatus of the pressure in the crankcase is greater than the pressure in the intake manifold, this also guaranteed one-way valve by high pressure to the air-transmitting function of low pressure.
With turbo charged automobile because the introducing of turbosupercharger has changed the pressure condition in the intake manifold, first: when engine low rotation speed turbosupercharger did not start, the motor natural aspiration still was negative pressure in the intake manifold; Second: after high rotating speed turbosupercharger started in the motor, motor was forced air inlet, was malleation in the intake manifold, and the gas handling system before the turbosupercharger is a negative pressure; The crankcase bleed pipe of so simple band one-way valve can not be realized the ventilation of above two kinds of pressure conditions.
Summary of the invention
The present invention designs a kind of pipeline assembly, can the gas blowby under the turbosupercharged engine slow-speed of revolution situation be imported intake manifold, and the gas blowby under the high speed conditions in the turbosupercharged engine is imported the turbosupercharger front end.Realize the crankcase ventilation of turbosupercharged engine.
The present invention proposes a kind of pipeline assembly 1, by crankcase give vent to anger sebific duct 2, repeatedly kick into gas manifold sebific duct 3, connect 4 three sebific ducts of turbosupercharging sebific duct, valve unit 5 and 6 clips and form; Give vent to anger sebific duct 2 of crankcase connects crankcase and valve units 5, and intake manifold sebific duct 3 connects valve unit 5 and intake manifold, turbosupercharging sebific duct 4 connection valve unit 5 and turbosupercharger; Valve unit 5 of the present invention comprises two valve diaphragms; Be intake manifold diaphragm 6 and company's turbosupercharging diaphragm 7; Repeatedly kick into gas manifold diaphragm 6 at give vent to anger sebific duct 2 and repeatedly kicking between the gas manifold sebific duct 3 of crankcase; Connect crankcase and intake manifold, diaphragm 7 is given vent to anger between sebific duct 2 and the company's turbosupercharging sebific duct 4 at crankcase, connects crankcase and turbosupercharger;
Valve unit 5 connecting end external diameters of the present invention than in the sebific duct through big 1～2mm,
The clip that the present invention uses is the spring clip;
Pipeline assembly of the present invention can be realized under engine low rotation speed situation; Connecting turbosupercharging diaphragm 7 closes; Repeatedly kick into gas manifold diaphragm 6 and open, gas blowby is introduced the crankcase sebific duct 2 of giving vent to anger and is got into and repeatedly kick into gas manifold sebific duct 3 backs and get into intake manifold through repeatedly kicking into gas manifold diaphragm 6;
Pipeline assembly of the present invention can be realized in the motor under the high speed conditions; Repeatedly kicking into gas manifold diaphragm 6 closes; Connect turbosupercharging diaphragm 7 and open, gas blowby introducing crankcase is given vent to anger sebific duct 2 through even getting into turbosupercharger behind turbosupercharging diaphragm 7 company's of entering turbosupercharging sebific ducts 4.
The present invention realizes through following principle:
Under turbosupercharged engine slow-speed of revolution situation, the motor natural aspiration, as shown in Figure 3; In the intake manifold is negative pressure P2, and the turbosupercharger front end is negative pressure P3, is malleation P1 in the crankcase; Because intake manifold is near from cylinder, cylinder do work intake manifold and crankcase when air-breathing the pressure gradient more suddenly: P1＞P3＞P2, repeatedly kick into gas manifold diaphragm 6 and open; Connect turbosupercharging diaphragm 7 and closed even turbosupercharging sebific duct 4; Gas blowby is drawn by negative pressure by crankcase, gets into the crankcase sebific duct 2 of giving vent to anger, and gets into and repeatedly kicks into gas manifold sebific duct 3 backs and introduce intake manifold through repeatedly kicking into gas manifold diaphragm 6.
Under high speed conditions in the turbosupercharged engine, turbosupercharger is started working, and air is pressed into motor; As shown in Figure 4, be malleation P1 in the crankcase, be malleation P4 in the intake manifold; The turbosupercharger front end is negative pressure P5, the malleation P4 in the intake manifold be higher than in the crankcase malleation P1 promptly: P4＞P1＞P5, repeatedly kick into gas manifold diaphragm 6 and closed and repeatedly kick into gas manifold sebific duct 3; Connecting turbosupercharging diaphragm 7 opens; Gas blowby is drawn by negative pressure by crankcase, gets into the crankcase sebific duct 2 of giving vent to anger, and introduces the turbosupercharger front ends through connecting turbosupercharging diaphragm 7 company's of entering turbosupercharging sebific ducts 4 backs.
Through repeatedly kicking into gas manifold diaphragm 6, the even opening and closing of turbosupercharging diaphragm 7, the crankcase ventilation hose assembly is introduced engine aspirating system with the gas blowby that produces under the turbosupercharged engine all working situation, participates in next air feed circulation, realizes crankcase ventilation.
