柴油发机电活塞环部位的异响是什么原因

作者:澳门金莎娱乐网站厂家 发布日期:2016-08-30 来源:www.0755fdjz.com 点击:

 柴油发动机汽缸内的异响可归纳为活塞敲缸声、活塞销敲击声、活塞顶撞击缸盖声、活塞顶撞击声、活塞环敲击声、气门敲击声及汽缸爆震声等几种。Now介绍活塞内的异响--
活塞环部位的异响主要有活塞环的金属敲击声、活塞环的漏气响声及积碳过多引起的异常响声。 
(1)活塞环的金属敲击声响。发动机长期work下,汽缸壁遭到磨损,但汽缸壁上部与活塞环接触不到的区域却险些保持着原几何形状与尺寸,这就使汽缸壁生成了一个台阶。如果用的是旧缸垫或是更换的新缸垫偏薄,work中的活塞环就会与缸壁台阶相碰撞,发出一种钝哑的“噗噗”的金属碰击声。若发动机转速升高,该异响也会随之增大。其余,若活塞环折断或活塞环与环槽间隙过大,也会引起较大的敲击声。 
(2)活塞环的漏气响声。活塞环弹力减弱,开口间隙过大或开口重叠,汽缸壁拉有沟槽等均会遭成活塞环漏气。其声响为一种“喝喝”或“嘶嘶”声,严重漏气时则发出“噗噗”的声音。其诊断方法是,在发动机水温达到80℃如该时熄火,这时可向缸内注入少许新鲜干净的机油,摇转曲轴数圈下,重新启动发动机,此时若异响消失,但不久下又出现,则可断定为活塞环漏气。 
(3)积碳过多的异常响声。积碳过多时,缸内传出的异响是一种尖锐的声音,由于积碳被烧红,发动机有点火过早的症状,而且不易熄火。活塞环部位积碳的形成,主要是由于活塞环与汽缸壁密封不严,开口间隙过大,活塞环装反,环口重合等原因,遭成润滑油上窜, 摄氏高压气体下窜,在活塞环部位燃烧,致使形成积碳甚至粘住活塞环,使活塞环失去弹性与密封感化。一般更换规格合适的活塞环下,此易于 障即可排除。
