伊发发动机(代号4VD14.5/12-1-1SRW)为原东德进口产品,用在E512/514型联合收割机及ZT-323-2型拖拉机上。这种发动机功率大,耗油省,深受用户好评。然而它最大的缺点是易烧瓦,给用户造成了很大的经济损失。笔者曾遇到过多起伊发发动机烧瓦故障,现举几个比较典型的实例如下。 1.机油粗滤芯损坏机油粗滤芯损坏后,机油中的胶状物质大量进入主油道,致使瓦片处供油中断,引起烧瓦。这时,油压表并没有油压低的显示(有时因油道堵塞,油压表有稍高的显示),驾驶员不易发现问题,直至发动机通 Yifa engine (Code 4VD14.5 / 12-1-1SRW) is the original East German imported products, used in E512 / 514 combine harvester and ZT-323-2 tractor. This engine power, fuel-efficient, praised by users. However, its biggest drawback is easy to burn tile, to the user caused a great economic loss. I have encountered too many engines from the fat tile failure, we will now give you a few more typical examples are as follows. 1. Oil rough filter damage Oil coarse filter damage, a large number of jelly oil in the main oil into the main oil, resulting in the tile at the interruption of oil supply, causing the burning tile. At this moment, the hydraulic gauge does not have the low oil pressure display (sometimes because of the oil channel blockage, the hydraulic gauge has a slightly higher display), the driver is not easy to find the problem until the engine pass
