农机手自行维修柴油机的不少。姑且不论技术水平如何,由于设备条件的限制,柴油机上的一些重要部件,拆动后易引起不必要的麻烦,故建议尽量不要随便拆动。 (1)气门组合。柴油机难启动时,不一定就是“气门撒气”。往往拆散后才发现,气门与气门座接触基本良好。等找到柴油机难启动的真正原因将气门重新装复后再试,气门却真的严重撒气了。这是因为气门与气门座各点材质硬度不会完全一样,一些部位还可能附着尘粒或氧化物。柴油机长时间运行,会形成气门与气门座
Agricultural machine repair their own hands a lot of diesel engine. Regardless of the technical level, due to equipment limitations, some of the important components on the diesel engine can easily cause unnecessary troubles after dismantling. Therefore, it is recommended that you do not disassemble whenever possible. (1) valve combinations. Difficult to start the diesel engine, not necessarily “valve spill.” Often disassembled only to find that the valve and valve seat basically good contact. Die hard to find the real reason for the hard to start the valve re-installed after the test, the valve is really serious gas. This is because the material hardness of the valve and valve seat points will not be exactly the same, some parts may also attach dust particles or oxides. Diesel engine running for a long time, will form a valve and valve seat
