Internal combustion engine having integral anti-polishing ring

摘要

An anti-polishing ring (143) formed to be integral with the cylinder head (132) of a diesel locomotive engine (120). A top portion (140) of a piston (128) of the engine is received by a skirt portion (142) of the cylinder head. The skirt portion has a diameter D4 that is greater than the piston diameter D3 but more than the diameter D1 of a cylinder liner (126). A coolant passage (148) may be formed in the cylinder head proximate the integral anti-polishing ring.
