1活塞环的作用活塞环结构简单、圆环形态、中间开口,留给人的第一印象并不起眼,而且在发动机的制造总成本中,它所占比例小,但是它却是发动机所有配附件中惟一做三个方向(轴向、径向、回转)运动的部件,能起到保持气密性、控制机油、冷却活塞、防止活塞与缸壁猛烈碰撞等重要作用。它的性能优异将直接影响发动机的工作表现和使用寿命。活塞环是一种
The role of a piston ring Piston ring structure is simple, circular ring shape, the middle of the opening, leaving the first impression is inconspicuous, and the total cost of the engine manufacturing, it is a small proportion, but it is all the engine Accessories in the only three directions (axial, radial, rotary) movement of the components, can play to maintain air tightness, control oil, cooling piston, piston and cylinder wall to prevent violent collision and other important role. Its excellent performance will directly affect the engine performance and service life. Piston ring is a kind
