Analysis of marine diesel engine parts abnormal color of marine diesel engine


The color of the marine diesel engine is abnormal. When the marine diesel engine is working normally, the exhaust gas is light gray, but a black smoke will appear when accelerating. Therefore, when the color is abnormal, the following phenomena occur:


⑴ Black smoke is coming out. This is a characteristic of incomplete combustion of marine diesel engines. At this time, there are a large number of solid particles in the exhaust gas, sometimes even with sparks, and accompanied by an increase in exhaust temperature.


⑵ White smoke. This is a characteristic of water or fuel vapor in the exhaust gas of marine diesel engines. At this time, the exhaust gas discharged from the marine diesel engine becomes a white mist, accompanied by a decrease in the power of the marine diesel engine and an unstable speed.


⑶ blue smoke. This is the characteristic of a large amount of lubricating oil vapor in the exhaust gas. At this time, the waste discharged from the marine diesel engine is in the form of blue mist. Accompanied by choking smoke and increased oil consumption of marine diesel engines.
