Abstract
The utility model relates to an oil-gas separator for a diesel engine, which comprises a breather casing, a breather cover plate and a breather filtering cover plate. The inner wall of an air inlet of the breather casing is uniformly coated with curing sealant in the circumferential direction; and then the breather filtering cover plate is buckled and tightly pressed. The curing sealant is coated on the breather casing integrally along a T-shaped groove on the whole top surface, and the breather cover plate is buckled and tightly pressed. The oil-gas separator for the diesel engine adopts an internal oil return cavity, so that the separated engine oil can flow back into a cylinder cover hood of the engine for recycle use. Simultaneously, the oil return cavity adopts a structure of a funnel-shaped rotary hollow body, so as to prevent mutual interference of refluent engine oil and air inlet airflow. In the oil-gas separator for the diesel engine, a special oil return pipe is not required to be arranged outside the casing of the oil-gas separator, so that the cost is reduced, and the reliability of the oil-gas separator and the neat and artistic appearance of the whole engine is ensured.
Description
Technical field:
The utility model belongs to field of internal combustion engine, relates to a kind of diesel engine oil gas separating device.
Background technique:
The diesel engine oil gas separating device is that the Oil-gas Separation that crankcase is discharged is the gentle device of oil, to reduce the mist of oil pressure in the crankcase.The engine oil recycle system that wherein isolated machine oil answers drainage to postback motivation carries out recirculation.If the design of deaerator can not be satisfied the needs of motor, then can have a strong impact on the normal operation of motor.The existing most complex structure of deaerator, machine oil after the separation can not recycle in the directly drainage air return cylinder housing, special-purpose return tube drainage need be set outside shell separator return diesel engine oil pan, complex forms not only, and the exterior line that increases can influence the Diesel Engine Complete Machine beautiful shape.
Fast development along with China's diesel engine industry technology, the diesel engine strengthening degree is more and more higher, how diesel engine realizes that effective Oil-gas Separation also becomes a problem that can not be ignored, and design has rational Oil-gas Separation and oil return structure, becomes the key of design high performance diesel oil gas separating device.
The model utility content:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, simple and practical diesel engine oil gas separating device, can be installed on engine air cylinder cap top easily, have specially designed inner oil back chamber, can recycle separating back direct the importing in the valve mechanism cover of liquid oil.
The technical solution of the utility model is: a kind of diesel engine oil gas separating device comprises that ventilator housing, resuscitation apparatus cover plate, resuscitation apparatus filter cover plate; Ventilator housing suction port internal face along the circumferential direction evenly is coated with to solidify sealer, again resuscitation apparatus is filtered cover plate and buckle and compress.In the T connected in star of ventilator housing upper edge whole top, be coated with solidifying sealer, and the resuscitation apparatus cover plate buckled compress.
The oil back chamber height H is 17mm～19mm in the ventilator housing, and oil back chamber oral area upper end inside radius RI is R5mm～R7mm, and oil back chamber oral area lower end inside radius RJ is R2mm～R4mm, and oil back chamber wall thickness K is 2mm～3mm.
Ventilator housing inner chamber bottom surface has oil-return groove, and its opening scope angle L is 18 °～22 °, and oil-return groove height M is 1mm～2mm.
The utility model can reach following beneficial effect: this separator has adopted the inside oil back chamber of particular design, can make that isolated machine oil directly is back in the engine air cylinder cap in the deaerator.And, avoided interfering with each other with the suction port air-flow because adopted the structure of funnel shaped rotation hollow body.This separator is simple in structure, and Perfect in shape and function can be effectively with Oil-gas Separation, and the direct drainage of the machine oil after will separating postbacks in the engine cylinder housing and recycles.This separator beautiful shape does not need not only to have reduced cost by special-purpose return tube is set outside the deaerator housing, and has guaranteed the neat and artistic of the reliability of deaerator and motor machine shape.
Description of drawings:
Fig. 1 is the utility model diesel engine oil gas separating device structure sectional view;
Fig. 2 is a ventilator housing plan view in the utility model diesel engine oil gas separating device;
Fig. 3 is a ventilator housing B-B sectional view in the utility model diesel engine oil gas separating device;
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the diesel engine oil gas separating device comprises: ventilator housing 1, resuscitation apparatus cover plate 2, resuscitation apparatus filter cover plate 3; Ventilator housing 1 suction port internal face along the circumferential direction evenly is coated with to solidify sealer, again resuscitation apparatus is filtered cover plate 3 and buckle and compress.In the T connected in star of ventilator housing 1 upper edge whole top, be coated with solidifying sealer, and resuscitation apparatus cover plate 2 buckled compress.
Shown in Fig. 2,3, oil back chamber is on ventilator housing 1, and the oil back chamber height H is 17mm～19mm, and oil back chamber oral area upper end inside radius RI is R5mm～R7mm, and oil back chamber oral area lower end inside radius RJ is R2mm～R4mm, and oil back chamber wall thickness K is 2mm～3mm.
Shown in Fig. 2,3, oil-return groove is in oil back chamber and intersection area, ventilator housing 1 inner chamber bottom surface, and its opening scope angle L is 18 °～22 °, and oil-return groove height M is 1mm～2mm.
The utility model diesel engine oil gas separating device is installed in the engine air cylinder cap top.During engine operation, the oil gas of scurrying in the crankcase enters deaerator by the road, after centrifugation, the specially designed inner oil back chamber that has owing to this deaerator, so liquid oily gravitate enters in the valve mechanism cover along oil back chamber, finally flow back to crankcase and recycle, and the gas of gaseous state enters intake duct through connecting tube.
