What are the causes of excessive engine exhaust?

[AllieLynn]

Wear of cylinder liners and pistons, leading to a decrease in engine output power, results in excessive exhaust from excavator engines. Below is more information about engine wear: 1. During combustion, the engine needs to draw in air, and the dust in the air will also be sucked in. Even with an air filter, some dust can still enter the engine. Even with lubricants, the wear caused by these dust particles cannot be eliminated, and this phenomenon is more severe in areas with high wind and sand. 2. After the engine stops running, cooling from high temperature to low temperature can cause condensation inside the engine, which can severely corrode metal components. 3. When gasoline burns, it produces many harmful substances. These substances not only corrode the cylinders but also have a corrosive effect on important engine components, such as the camshaft and crankshaft.
