The described perpendicular structure of back oil road for boring moulding on cylinder head of putting; Described crooked back oil road is the structure of boring moulding on cylinder block.
The utility model also provides a kind of motor, and it has above-mentioned motor multichannel oil-returning structure.
The utility model provides a kind of automobile simultaneously, and it comprises above-mentioned motor.
Owing to having adopted technique scheme, compared with prior art, obtained technological progress is the utility model:
1. motor multichannel oil-returning structure of the present utility model, the second back oil road of setting up is communicated with oil sump minimum point position of living in and oil sump, lubricant oil in oil sump is back in oil sump in time, has avoided causing mist of oil to enter firing chamber participation burning because lubricant oil accumulates; Simultaneously, the oil return gross area of drainback passage increases, and the oil return ability of motor strengthens;
2. perpendicularly put the structure setting that back oil road, crooked back oil road depend on respectively cylinder head, cylinder block, to guarantee that lubricant oil refluxes fast, can not accumulate around the corner;
3. perpendicular back oil road, the crooked back oil road put, by casting, both met application requirements, reduced again peripheral pipeline and the leakage of oil hidden danger of motor, reduced the cost of motor.
In sum, motor multichannel oil-returning structure of the present utility model has characteristics simple in structure, low cost of manufacture.
Motor multichannel oil-returning structure of the present utility model is applicable to comprehensively being located on the cylinder block and cylinder head of various motors, further is applied on various vehicle motors and automobile.
