Blue smoke from diesel engine
發(fā)布時(shí)間:2022-06-03
1. Cylinder compression pressure: if there is a special tool to detect the cylinder compression pressure, the wear of the piston ring and cylinder liner of the cylinder can be confirmed by measuring the cylinder compression pressure. If the measured pressure is lower than the standard value, it indicates that the piston ring and cylinder liner of the cylinder are seriously worn. If there is no special tool for measuring cylinder pressure, remove the cylinder head and observe the wear of piston ring and cylinder liner.

2. Respirator: if there is a problem with the respirator, the pressure of crankcase exhaust gas may be high, which may cause blue smoke from the diesel engine.

3. Lubricating oil volume: if too much lubricating oil is added, the exhaust gas pressure of crankcase will be too high, and the diesel engine may also emit blue smoke.
