What are the signs of engine cylinder scuffing?

[Patel]

The engine will produce abnormal noises, the output power will rapidly decrease, and there will be severe oil burning, blue smoke, or even crankcase explosion. Here is some information about cylinder scuffing: 1. Introduction 1: Cylinder scuffing is one of the common faults in automobile engines. Engine cylinder scuffing refers to deep grooves being formed on the inner wall of the cylinder, causing the piston, piston rings, and cylinder wall to lose their sealing ability during friction, resulting in reduced cylinder compression pressure and loss of power. 2. Introduction 2: The causes of cylinder scuffing are very complex, including design-related factors such as material selection, determination of clearance size, whether the installation of the device is properly aligned, whether the structural layout is reasonable, whether the surface roughness is appropriate, and whether the lubrication and cooling arrangements are adequate.
