Description
Technical field
The utility model relates to oil and gas separating system field, particularly crankcase oil gas separation system.
Background technique
Present stage, country was more and more stricter to car load engine emission statutory standard, with regard to motor itself, improve emission standard and will guarantee as far as possible that mixed gas fully burns, can guarantee under the clean-burning operating mode at motor, can cause deterioration of emission owing to carried a large amount of machine oil in the inflammable mixture, and the machine oil in the mixed gas partly to originate be exactly that crankcase waste gas carries, for reducing the content of machine oil in the inflammable mixture, crankcase waste gas with regard to carrying out Oil-gas Separation through oil and gas separating system, was separated the machine oil about 90% before entering intake manifold and air induction hose.At present, the oil and gas separating system of crankcase is arranged on outside the crankcase more, and component are more, and structure is comparatively loaded down with trivial details, and increases the weight of motor.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, is arranged in the crankcase oil gas separation system on the cover cap of crankcase valve chamber.
For achieving the above object, the utility model has adopted following technological scheme: a kind of crankcase oil gas separation system, comprise the cover cap that is provided with cavity and the cover plate that is fixed on the cover cap below, described cover cap and cover plate enclose to consist of and are airtight cavity, this cavity is provided with gas inlet hole and air outlet hole, described cover plate is provided with the side that oil outlet and this oil outlet are positioned at air outlet hole, in the cavity of cover cap at least parallel interval two filter plates are set, the two ends of filter plate are affixed with the inwall of cavity respectively, the through hole that offers on the filter plate on a plurality of through holes and adjacent two filter plates staggers mutually, described gas inlet hole and air outlet hole lay respectively at the both sides of filter plate, and oil outlet and air outlet hole are positioned at the same side of filter plate.
Owing to adopt above technological scheme, the waste gas of crankcase enters cavity through the gas inlet hole, because very close to each other between the inwall of filter plate and cavity, waste gas can only pass from the through hole on the filter plate, when waste gas can directly strike on the plate face of second filter plate after the through hole on first filter plate passes, the drop that carries in the waste gas during bump can get off because bump is separated, drop on the cover plate and from oil outlet at action of gravitation afterwards and discharge, the Oil-gas Separation of the realization crankcase waste gas that this structure energy is good, oil and gas separating system is arranged in the cover cap of crankcase, reduce component, simplified structure alleviates the weight of motor.
