《汽车维护与修理》编辑部: 自《汽车维护与修理》杂志出版以来,我基本上每期都看,从中学到了不少知识,在此,向你们说声:“谢谢”。最近有一辆普通型桑塔纳轿车由于烧润滑油,由我厂进行发动机总成大修,更换了曲轴轴承、连杆轴承、活塞、活塞环、液压挺柱、气门等。大修完毕后试车,就像没有压缩。检查电路、配气机构及气缸压力都正常,就是不能发车。起初认为是缸盖不平,更换了缸盖,故障依旧。 “Car Maintenance and Repair” Editorial: Since the publication of Car Maintenance and Repair magazine, I have basically read every episode and learned a great deal about it. Here I say “Thank you.” Recently, a common type of Santana sedan due to burning oil, engine assembly overhaul by our plant, replacing the crankshaft bearings, connecting rod bearings, pistons, piston rings, hydraulic tappet, valves and so on. After the overhaul test, like no compression. Check the circuit, with gas institutions and cylinder pressure are normal, that is, can not start. At first thought is uneven cylinder head, replace the cylinder head, the fault still.
