The diesel engine bellowed blue smoke.
Blue smoke is generally considered to be the performance of too much oil. The color is grayish blue, commonly known as blue smoke. It's essentially exhaust engine oil vapor.
Oil pan oil is too much, this only need to check the oil gauge can be judged. Excessive oil Excessive lubrication, into the combustion chamber, the formation of oil steam.
If there is not much oil in the oil pan, the first thing to consider is whether the supercharger seal ring is damaged when the new machine appears blue smoke. Also consider whether the piston ring is damaged. Whether there is the possibility of abnormal wear of piston cylinder liner.
The old engine should consider the supercharger, piston ring damage, but also consider the wear of the piston and cylinder liner. And whether there is a crack in the oil passage on the cylinder head and the oil enters the combustion chamber.
In addition to considering the above reasons, the diesel engine that has just been repaired should recall the installation direction of the piston ring. Although the piston ring is installed in the opposite direction, it will not damage any components, but it will cause the problem of blue smoke caused by oil entering the combustion chamber.
The improper use of another machine can also cause this phenomenon. That is, long-term low load operation, low load operation means that the body temperature is too low, the crankshaft connecting rod mechanism clearance is too small resulting in excessive wear, so that the oil into the combustion chamber. In fact, this kind of failure is not very common.
