所谓发动机连续烧瓦,是指发动机因某种原因造成烧瓦,经维修后工作时间很短,甚至在维修后起动试车时间内又发生烧瓦故障。造成连续烧瓦的主要原因如下:1.烧瓦后曲轴产生了变形和损伤多缸发动机烧瓦后会导致曲轴弯曲变形,使几道主轴颈不在一条直线上,曲轴运转起来几道轴瓦受力不均匀,使轴瓦与轴颈摩擦加剧, The so-called continuous burning of the engine, which means that the engine for some reason caused by burning tiles, the maintenance of the working time is very short, even after the start-up test repair time occurred in the bush failure. The main causes of continuous burning of the tile are as follows: 1. After the burning of the crankshaft deformation and damage caused by multi-cylinder engine will cause crankshaft bending deformation, so that a few main journals are not in a straight line, the crankshaft up and running several bearings Uneven, so that bushings and journal friction increased,
