Piston Ring Dynamic Loading And Wear (Service Life)
Piston ring dynamic loading occurs in addition an axial motion of the piston ring caused by the interactions of gas, mass, and friction forces.

Piston Liner Scratches
Piston / liner scratches caused by foreign particles, like dirt, debris or metal shavings, occur when abrasive foreign bodies in the engine oil.

Piston Ring Scratches And Breaks
Piston ring scratches and edge breaks is rare to see especially after very short run, some of the scratch or breaks can feel with a fingernail, or only can be seen from magnifier

Early Stage Liner Scratch
Scratches on liner is a very common failure type, which can lead to severe issues, such as increased oil consumption, loss of compression, and accelerated wear on the piston rings.

Measurement And Assessment Of Ring Grooves
Axial clearance is typically checked by inserting a feeler gauge between the ring and the top of the ring groove.
