How to Determine if an Engine Has Cylinder Scoring?

[Enid]

Here are the methods to determine if a car has cylinder scoring: 1. When cylinder scoring occurs, the car will experience jerking and the engine will produce significant abnormal noises, with reduced RPM and noticeably decreased power. 2. Cylinder scoring is caused by severe surface damage due to the mutual movement of the piston and cylinder, mostly resulting from localized destruction of the lubricating oil film on the moving parts. Here are some relevant details: 1. The cooling efficiency of the engine's cooling system, the quantity and quality of engine oil, and the working performance of the supply system are all critical factors that can cause fatal damage to the engine. 2. The causes of cylinder scoring include: (1) The clearance between the piston and cylinder is too small; (2) Insufficient lubrication between the piston and cylinder or incorrect oil selection; (3) Failure of the engine cooling system; (4) Low hardness or poor quality of the cylinder itself.
