The two-stroke engine includes an engine head, a cylinder block, and a lower block. The lower block is sealed from the engine head except for a cylinder bore in the cylinder block. A piston in the cylinder block has at least one compression ring groove for a compression ring to seal the lower block from the engine head. The piston also includes an oil control ring groove for an oil control ring to provide appropriate lubrication to the compression ring during each stroke of the piston. The piston further includes at least one drainage opening providing fluid communication between the outer circumference of the piston and an interior surface of the piston.
Moteur à deux temps comprenant une culasse, un bloc-cylindres et un carter moteur. Un piston dans le bloc-cylindre comporte au moins une gorge pour un segment de compression afin de sceller le carter moteur de la culasse. Le piston comporte également une gorge pour un segment racleur pour assurer la lubrification adéquate du segment de compression pendant chaque course du piston. Ce dernier comprend de plus au moins une ouverture d'évacuation assurant une communication fluidique entre la circonférence extérieure du piston et une surface intérieure du même piston.
