What Causes Excessive Smoke in a Four-Cylinder Diesel Engine?

[GabrielRose]

When a four-cylinder diesel engine operates under heavy load, the forces acting on all moving components increase, leading to greater deformation of the cylinder bore. If the piston rings cannot accommodate this deformation, engine oil may leak into the combustion chamber, resulting in excessive smoke. Solution: Use high-quality engine oil. Engine oil is highly susceptible to corrosion and aging under prolonged high-temperature conditions, causing the oil film to thin and making it easier for oil to enter the combustion chamber and participate in combustion. Therefore, using high-quality engine oil can significantly delay this phenomenon. Common Diesel Engine Faults: In daily use of diesel engines, some common faults directly affect the engine's service life and production efficiency. These include reduced engine power or black smoke emissions, oil leakage from the compressor end seal ring, and abnormal noises in the diesel engine.
