Cylinder Liner - Wear Rate Limit
Cylinder liner wear rate benchmark - 0.03–0.08 mm / 1000 h typical for 2-stroke; rising trend indicates oil or fuel issue.
Wear rate
0.060mm/1000 h
Remaining hours
46,667h
Formula, assumptions, and limits
$$r_{wear} = w / h, \quad t_{rem} = (L - w) / r$$
MAN ES: 0.03 mm/1000 h normal. > 0.1 mm → investigate ash ingress, overfeeding, improper BN, cooling issue. Scrap at 4 mm above original.
