| titleOfInvention | A kind of passenger car lightweight air cylinder sleeve of engine and preparation method thereof |
| abstract | The invention belongs to a kind of passenger car lightweight air cylinder sleeve of engine and preparation method thereof, cylinder jacket outer round surface is distributed with pit, the shape of pit includes dumbbell shaped, is just putting frustum, vermiform, four kinds of shapes of olecranon shape, in cylinder jacket outer round surface random distribution, the height of pit is 0.25 mm~1.1mm to four kinds of pits of shape.Cylinder jacket pit of the present invention highly only has 0.25~1.1mm, hence it is evident that reduces the blank cooling velocity during Cylinder Sleeve by Centrifugal Casting, so as to significantly improve metallographic structure, improves the antifriction performance of cylinder jacket, extends the service life of cylinder jacket；Simultaneously because the height fluctuation of pit is smaller, circularity fluctuation is substantially reduced during aluminum cylinder casting, reduces the possibility that machine oil scurries into combustion chamber, reduces combustion chamber exhaust emissions；Low clearance pit and excellent metallographic structure, can make cylinder jacket wall thickness reduce 1mm, cylinder sleeve of engine cylinder pintch is reduced by 2 more than mm. |
