Abstract: Steel pistons used in many internal combustion engines are generally composed of a skirt and a crown. The skirt's function is to reduce the lateral and rotational movement of the piston in the cylinder while the engine is in operation. Lateral and rotational frictional forces imparted to a piston during engine operation cause the piston to scrape off the lubricating oil film present on the cylinder wall. The reduced oil film thickness increases piston and cylinder wall wear due to metal to metal contact. The subsequent metal to metal contact produces a phenomenon called scuffing. This disclosure incorporates several design modifications to the piston and results in a significant reduction of the lateral and rotational motion of the piston during engine operation. The reduction of piston motion reduces the amount of oil film removed from the cylinder wall and increases lubrication efficiency. The increased lubrication efficiency realized reduces frictional wear power loss and scuffing.

The cylinder liner may generally include a cylindrical body configured to receive a piston assembly. The cylindrical body may further include a main body portion configured for selective engagement with an engine bore, and an upper flange configured to support the cylindrical body within the engine bore.

Abstract: A piston (20) for an internal combustion engine is provided. The piston crown (22) includes an interior surface that defines at least in part a cooling gallery (56) and a cooling gallery surface within the piston. An annular surface (80,82) may defines at least in part an annular passageway (74) that allows fluid communication between an outer surface of the piston and the cooling gallery. Opposing annular surfaces may be abutted with a predetermined force, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston. Further, an annular surface may extend into the cooling gallery to form a deflector (84) along the cooling gallery surface, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston.
