Abstract: A piston ring assembly includes a piston, and at least one piston ring positioned within a piston groove. Stabilization and support of the piston is provided by a support arrangement, including at least one support member positioned radially between a back wall of the ring groove and the piston ring. The support arrangement desirably acts to accommodate transverse loads exerted upon the piston during normal operation, and can optionally be configured for enhanced sealing of gasses. Improved engine output and efficiency are achieved

Abstract: A side rail is formed into a ring shape having its generally rectangular section that has an outer surface 3 formed with a pair of edge surfaces 5 of small radius, and an intermediate surface 6 of large radius of curvature formed between the edge surfaces 5. When the side rail is in the inclined condition in operation, each edge surface 5 can easily ride on oil film on cylinder 16 and allow the side rail 1 to perform smooth sliding movement on the inner surface of cylinder. The intermediate surface 6 efficiently scrapes lubricating oil on cylinder to form lubricating oil film of necessary and minimum thickness between an inner surface 17 of cylinder 16 and side rail 1. Also, the larger radius of curvature for forming the intermediate surface 6 provides a larger contact area to the inner surface 17 of cylinder 16 to improve wear resistance.

Abstract: An oil control ring for a piston of an internal combustion engine has an annular body defining a central axis. The ring has a U-shaped cross-section formed of a centrally positioned web extending parallel to the axis and a pair of axially spaced rail portions integrally connected to the web. Each rail portion extends radially outwardly with respect to the web, and an extremity of each rail portion defines a land extending parallel to the axis and adapted to sealingly engage a cylinder wall. Each land defines a pair of spaced chamfered sidewalls. Each sidewall extends contiguously from each land to define a chamfered edge adjacent the land. Finally, each chamfered edge defines a concave annular sidewall. The result is a reduction of land surface area in contact with the cylinder walls of an engine to provide improved performance, particularly during the engine break-in period.

Abstract: An oil ring for an internal combustion engine, comprising a metallic annular body (10) to be mounted around a piston (P) reciprocating inside a cylinder (C) of the engine, said annular body (10) having opposite lateral faces (11), an internal face (12) onto which will be seated a resilient expander (M), and an external contact face (13) to be seated against the internal face of the cylinder (C) and having a height (h) that is substantially smaller than the height (H) of the internal face (12). Each lateral face (11) is defined by one or more lateral face portions (11a, 11b), which are designed to reduce the moment of inertia of the annular body (10), giving higher conformability to the latter. Preferentially, but not exclusively, the annular body (10) can be further provided with channels (15, 16), extended along at least part of the ring hight and which are radially spaced back in relation to the external contact face (13).
