Abstract
The utility model belongs to the field of an internal-combustion engine, and relates to an oil-gas separation mechanism for a diesel engine. The internal-combustion engine comprises a ventilator shell, a ventilator cover plate and a ventilator filtering plate, wherein the ventilator cover plate is covered at an opening of the ventilator shell; the ventilator shell is internally provided with an oil-gas separation hole which is covered by the ventilator filtering plate; the inner wall at the lower end of the oil-gas separation hole is provided with an oil separation funnel; and the oil separation funnel is internally provided with an oil separation groove extending along the inner wall of the oil separation funnel in a ring shape. The oil separation funnel is used for separating oil so as to separate the oil from the gas; and the oil separation groove is gradually enlarged from top to bottom, so that the oil separation effect can be enhanced, and the oil-gas separation performance of the diesel engine can be improved.
Description
Technical field
The utility model belongs to field of internal combustion engine, relates to a kind of Oil-gas Separation mechanism of diesel engine.
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 increasingly high; 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.
Summary of the invention
The problem that the utility model will solve provides that a kind of oil return is effective, the Oil-gas Separation Oil-gas Separation mechanism of diesel engine completely.
The technological scheme that realizes the utility model purpose is following:
The Oil-gas Separation mechanism of diesel engine; It comprises ventilator housing, resuscitation apparatus cover plate and resuscitation apparatus filter plate; The resuscitation apparatus cover plate covers at the ventilator housing opening, is provided with the Oil-gas Separation mouth in the ventilator housing, is covered by the resuscitation apparatus filter plate on the Oil-gas Separation mouth; Oil-gas Separation mouth lower end inwall is provided with from oil funnel, should be provided with that wall circular extends in the funnel in the oil funnel from oil groove.
Described from oil groove from top to down width increase gradually.
Passing through of the utility model from the oil funnel separating oil, thus with Oil-gas Separation,, strengthen the effect of separating oil through the setting that increases gradually from top to down from oil groove, improved the performance that diesel engine oil gas separates.
Description of drawings
Fig. 1 is the structural representation of model utility;
Fig. 2 be among Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1; The Oil-gas Separation mechanism of diesel engine, it comprises ventilator housing 1, resuscitation apparatus cover plate 2 and resuscitation apparatus filter plate 3, resuscitation apparatus cover plate lid 2 is at ventilator housing 1 opening; Be provided with Oil-gas Separation mouth 4 in the ventilator housing 1; Covered by resuscitation apparatus filter plate 3 on the Oil-gas Separation mouth 4, Oil-gas Separation mouth 4 lower end inwalls are provided with from oil funnel 5, should be provided with that wall circular extends in the funnel in the oil funnel 5 from oil groove 6.Described from oil groove 6 from top to down width increase gradually since from oil groove 6 have go up under opening increase, fine from oily effect.
Claims (2)
1. the Oil-gas Separation mechanism of diesel engine; It is characterized in that: it comprises ventilator housing, resuscitation apparatus cover plate and resuscitation apparatus filter plate; The resuscitation apparatus cover plate covers at the ventilator housing opening, is provided with the Oil-gas Separation mouth in the ventilator housing, is covered by the resuscitation apparatus filter plate on the Oil-gas Separation mouth; Oil-gas Separation mouth lower end inwall is provided with from oil funnel, should be provided with that wall circular extends in the funnel in the oil funnel from oil groove.
2. the Oil-gas Separation mechanism of diesel engine according to claim 1 is characterized in that: described from oil groove from top to down width increase gradually.
