Abnormal combustion protection in an engine and piston configuration for same
An engine (12) includes a cylinder liner (34) and a piston (40) movable within the cylinder liner (34), a crevice (68) formed between a top land (64) of the piston (40,) and the cylinder liner (34), and an oil entry clearance (70) formed between a top ring of the piston (40) and the cylinder liner (...

| description | An engine (12) includes a cylinder liner (34) and a piston (40) movable within the cylinder liner (34), a crevice (68) formed between a top land (64) of the piston (40,) and the cylinder liner (34), and an oil entry clearance (70) formed between a top ring of the piston (40) and the cylinder liner (34). The engine (12) also includes an abnormal combustion inhibitor (72) having an oil recapture surface (74) exposed to the crevice (68) and oriented to limit migration of oil (75) from the crevice (68) toward a combustion chamber (36) in the engine (12). The abnormal combustion inhibitor (72) includes a groove structure (95) having as a substrate at least one of the cylinder liner (34) or the piston (40). Related methodology is also disclosed. |
