Sometimes it can be found that there is blue smoke in the exhaust of the automatic feeding mixer, and the exhaust pipe drips oil. Here's why.

若机油大量地窜入燃烧室并被汽化，排气便带蓝烟。蓝烟实际上是机油蒸汽的再凝结。有时，柴油机在冷起动或低负荷时冒蓝烟，但暖车或负荷增大后便消失，这往往是由于机油蒸汽被烧掉，当烧的不完全还会冒黑烟。

If a large amount of oil into the combustion chamber and vaporized, exhaust with blue smoke. Blue smoke is actually recondensation of oil vapor. Sometimes, the diesel engine gives off blue smoke during cold start or low load, but disappears after warm-up or load increase. This is often due to the oil vapor being burned off, and black smoke will be emitted when the combustion is not complete.

窜机油冒蓝烟的后果，是机油消耗量迅速上升，并产生大量的积炭和其它燃烧产物，使喷油器、活塞环的工作性能变坏，加速活塞环、气缸套等零件的磨损，应尽量避免。

The result of blue smoke from oil channeling is that the consumption of engine oil increases rapidly, and a large amount of carbon deposit and other combustion products are produced, which makes the working performance of fuel injector and piston ring worse, and accelerates the wear of piston ring and cylinder liner, which should be avoided as far as possible.

1.带有倒角的活塞环或扭曲环将方向装错，反而将机油泵(混泥土搅拌车)入燃烧室。

1. The piston ring or twisted ring with chamfer will be installed in the wrong direction, instead, the oil pump (concrete mixer) will be put into the combustion chamber.

2.柴油机长期在低负荷下工作(负荷小于30～50%)，气缸内压力低。

Under low load for a long time, the working pressure of diesel engine is less than 2.50% under low load.

3.磨合不良。试验表明，新的或大修后的柴油机一般需磨合30～40小时才能达到良好的技术状况。未经良好磨合而直接带正常负荷工作是冒蓝烟的常见原因。

3. Poor running in. The test shows that the new or overhauled diesel engine generally needs to run in for 30-40 hours to reach a good technical condition. It is a common reason for blue smoke to work directly with normal load without good running in.

4.活塞环、气缸套内表面光洁度、椭圆度、锥度及配合间隙不符合要求，或由于连杆弯曲、主轴孔与气缸套不垂直而使活塞偏磨，也引起窜油冒蓝烟。

4. The internal surface finish, ovality, taper and fit clearance of piston ring and cylinder liner do not meet the requirements, or the piston is eccentric worn due to the bending of connecting rod, and the main shaft hole is not vertical to the cylinder liner, which also causes oil leakage and blue smoke.

5.油底壳内机油过多，机油压力过高，粘度太小，活塞环磨损及失去弹性或活塞与气缸套间隙过大，油浴式空气滤清器的油盘内加油过多等等。

5. There is too much oil in the oil pan, the oil pressure is too high, the viscosity is too small, the piston ring is worn and lost elasticity, or the clearance between the piston and the cylinder liner is too large, the oil pan of the oil bath air filter is overfilled, etc.
