Abstract

A reciprocating engine (1) includes a piston (2) having a piston upper body (8) that has an upper surface (3) for receiving combustion/expansion gas pressure and also has a land section (7) provided with piston ring grooves (4, 5, 6); a skirt section (9) formed below the piston upper body (8); and a piston boss section (11) for supporting a piston pin (10). The piston upper body (8) is formed eccentric to the anti-thrust side (13) relative to the center line (14) of the piston (2).
