What sound does engine cylinder scoring make?

[AlexanderAnn]

If there are slight signs of engine cylinder scoring, the engine will exhibit the following conditions during idle operation: 1. There is usually a tapping or knocking sound. 2. As the temperature rises, the sound becomes duller and is accompanied by engine shaking. 3. In severe cases of cylinder scoring, the engine may stall directly. Additional information: 1. Definition of engine cylinder scoring: Engine cylinder scoring refers to obvious longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the movement range of the piston rings. In severe cases, adhesive wear may occur, leading to difficulties in starting the engine or causing it to stall. 2. Causes of cylinder scoring: The root cause of cylinder scoring is the difficulty in forming an oil film between the inner wall of the cylinder and the piston rings or piston, resulting in poor lubrication or even dry friction.
