Abstract

Ce moteur à combustion interne comporte au moins un piston 13 présentant en section transversale une forme oblongue, qui est monté de façon à effectuer un mouvement de va-et-vient en contact de glissement dans un cylindre 12 de forme correspondante, un vilebrequin 14, et plusieurs bielles 17 qui relient le piston et le vilebrequin, les bielles 17 étant espacées dans une direction parallèle à l'axe de rotation du vilebrequin.This internal combustion engine comprises at least one piston 13 having in cross section an oblong shape, which is mounted so as to effect a reciprocating movement in sliding contact in a cylinder 12 of corresponding shape, a crankshaft 14, and a plurality of connecting rods 17 which connect the piston and the crankshaft, the connecting rods 17 being spaced in a direction parallel to the axis of rotation of the crankshaft.
