What Causes Diesel to Enter the Engine?

[OLukas]

Diesel entering the engine oil in a diesel engine may be caused by damaged sealing rings in the fuel injection pump plunger sleeve, excessive clearance between piston rings and cylinder walls, or low cylinder pressure. Below is relevant information about automotive engines: Overview: An automotive engine is a device that provides power to a vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Based on the power source, automotive engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. Additional Information: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into mechanical energy through piston movement and delivering power output. Gasoline engines feature high rotational speeds, lightweight construction, low noise levels, easy starting, and lower manufacturing costs. Diesel engines, on the other hand, have higher compression ratios, superior thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.
