低压油路漏油比较容易发现和处理,而漏气就不那么直观,因此只有正确判断漏气部位,才能缩小查找范围。具体做法如下:首先检查输油泵是否完好,其弹簧是否折断、活塞是否严重磨损等。然后再分2种情况检查:若发动机运转情况良好且能正常熄火,而再启动时困难,则 Low-pressure oil leakage easier to find and deal with leakage, and leakage is not so intuitive, so only correctly determine the leak site, to narrow the search range. Specific practices are as follows: First check whether the intact oil pump, the spring is broken, the piston is seriously worn and so on. And then divided into 2 kinds of situations to check: If the engine running in good condition and normal flameout, but difficult to restart, then
