Abstract
The utility model relates to a waste gas exhaust device for an engine crank case, and belongs to an engine accessory. The utility model is characterized in that a pipe opening of a gas outlet pipe of a respirator communicated with the crank case is provided with a wheel disc with blades; a rotation shaft of the wheel disc is connected with a rotation component of an engine or a matched machine; the wheel disc forms a cone shape; the conic surface is provided with the blades; the wheel disc is arranged in a horn mouth of the pipe opening of a gas outlet pipe; or a crank pulley which is connected with the crank case is directly used as the wheel disc, and a web of a belt pulley is provided with axial flow blades. The utility model uses the rotation member of the engine to drive the blades to rotate, pumps the waste gas of the crank case out, reduces the internal pressure of the crank case, prevents waste gas containing engine oil from entering a gas inlet system and enhances the operational reliability of a gas cylinder and the performance of the engine.
Description
Technical field
The utility model relates to the unit of exhausting waste gas that reduces engine crankcase pressure, belongs to a kind of engine accessory power rating.
Background technique
At present motor leaks into exhaust gas pressure in the crankcase in order to reduce by piston and piston ring place, reduce the seepage that the motor that brings owing to the crankcase pressure rising respectively seals the position, generally adopt for naturally aspirated engine suction tude directly is connected with the resuscitation apparatus that is connected with crankcase, the negative pressure that is produced in the suction tude when the aspirating stroke by motor with the Abgasabsaugung in the crankcase in suction tude; For the motor of part, generally be before the total mouth of exhaust-gas turbocharger air inlet, directly to be connected with the resuscitation apparatus that is connected with crankcase by pipeline with exhaust-gas turbocharger.Adopt above measure, though can reduce the engine crankcase internal pressure, but after motor turns round through certain hour, because the waste gas in the crankcase contains certain machine oil, and the machine oil combustion performance is relatively poor, cause valve, air valve seat ring, interior surface of cylinder liner, piston crown ring bank and the serious carbon distribution of piston ring easily, thereby cause with the upper part inordinate wear.In addition, motor for the band exhaust-gas turbocharger, also can be because of having sucked the crankcase waste gas that contains machine oil at total mouthful of place of air inlet, make easily and paste a large amount of greasy filth on the compressor impeller of exhaust-gas turbocharger, increase the resistance to motion of impeller, cause the gas compressor blade wheel speed to descend, thereby the boost pressure at the blower outlet place of exhaust-gas turbocharger is reduced, increased the fuel consumption rate and the smoke intensity of motor.
The model utility content
The technical problems to be solved in the utility model provides a kind of engine crankcase waste gas venting gas appliance, use this device and can reduce engine crankcase pressure, make crankcase include machine oil waste gas and do not enter engine aspirating system, thus the reliability and the engine performance of raising cylinder operation.
The technical solution of the utility model is: the engine crankcase waste gas venting gas appliance, comprise the resuscitation apparatus and the resuscitation apparatus steam outlet pipe that are connected with crankcase, improvements are the wheel discs that are provided with the band blade at resuscitation apparatus steam outlet pipe mouth of pipe place, the rotating shaft of this wheel disc and motor or link to each other with rotary component on the motor supporting machinery.
Further scheme is: described wheel disc becomes cone-shaped, and the conical surface of cone is provided with blade, and this wheel disc is located in the horn mouth at resuscitation apparatus steam outlet pipe mouth of pipe place; Perhaps wheel disc is the crank pulley that is connected on the crankcase, and the web position of this belt pulley is provided with axial blade; The crank pulley end face is provided with the draught hood that communicates with the resuscitation apparatus steam outlet pipe.
Adopt above technological scheme, motor or with the rotary component of its supporting machinery on the wheel disc of mounting strap blade, rotation along with blade, by steam outlet pipe the waste gas in the crankcase is extracted out, thereby reduction crankcase pressure, prevent that the waste gas that contains machine oil from entering gas handling system, avoid cylinder part carbon distribution and inordinate wear or avoid on the pressure booster blower impeller pasting greasy filth and the increase that causes engine fuel consumption rate and smoke intensity, can effectively improve the reliability and the engine performance of cylinder operation in a word.
During the utility model fabrication and installation, the mouth of pipe proper extension of giving vent to anger of the resuscitation apparatus that is connected with crankcase, there is horn mouth at mouth of pipe place, and wheel disc is located in the horn mouth, strengthens the effect of bleeding; Perhaps directly utilize the crank pulley that is connected on the crankcase as wheel disc, the web position of belt pulley is provided with axial blade, and is provided with the draught hood that communicates with the resuscitation apparatus steam outlet pipe at the belt pulley end face, and structure is compact more, simplification, and effect is also better.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the another kind of structural representation of the utility model.
Embodiment
Example 1: see Fig. 1, the cone-shaped wheel disc 4 that has blade 3 is arranged in the horn mouth 2 at resuscitation apparatus steam outlet pipe 1 mouth of pipe place, and resuscitation apparatus is communicated with engine crankcase, and the rotating shaft of wheel disc links to each other with engine crankshaft.
Example 2: see Fig. 2, the web position that is connected the crank pulley 6 on the engine crankshaft is provided with axial blade 7, the belt pulley end face is provided with the draught hood 5 that communicates with resuscitation apparatus steam outlet pipe 1, the draught hood intracavity diameter rotates external diameter greater than axial blade, and draught hood and belt pulley end face leave gap delta=1.5mm.
Claims (4)
1, a kind of engine crankcase waste gas venting gas appliance, comprise the resuscitation apparatus and the resuscitation apparatus steam outlet pipe that are connected with crankcase, it is characterized in that being provided with the wheel disc of band blade, the rotating shaft of this wheel disc and motor or link to each other with rotary component on the motor supporting machinery at resuscitation apparatus steam outlet pipe mouth of pipe place.
2, by the described engine crankcase waste gas venting gas appliance of claim 1, it is characterized in that wheel disc becomes cone-shaped, the conical surface of cone is provided with blade, and this wheel disc is located in the horn mouth at resuscitation apparatus steam outlet pipe mouth of pipe place.
