Title:
PISTON ASSEMBLY FOR RECIPROCATING ENGINE
Document Type and Number:
Japanese Patent JP2020106031
Kind Code:
A
Abstract:
To provide a piston and a piston ring that are capable of reducing the lubricant consumption and the wear.SOLUTION: The distribution of combustion gases within an engine is controlled using, e.g., a radial channel 100 and/or an axial channel. For example, the combustion gases may exert pressure on an outer face 90 of a top ring 44 of a piston assembly 25. The radial channel 100 or the axial channel may transfer the combustion gases to a space 130 adjacent to an inner face 124 of the top ring 44, thus controlling the pressure gradient between the outer face 90 and the inner face 124.SELECTED DRAWING: Figure 4
