Abstract
A two-cycle engine is provided and has a cylinder with a combustion chamber delimited by a reciprocating piston. The engine has an inlet for fuel/air mixture, an outlet out of the combustion chamber for exhaust gas, and four transfer channels that open into the cylinder via inlet windows, and fluidically connect the crankcase with the combustion chamber as a function of the piston position. The transfer channels have a connecting portion to the crankcase, an ascending portion substantially parallel to the longitudinal axis of the cylinder, and an opening-out portion into the combustion chamber. The planes defined by that side wall of the transfer channel close to the outlet that is remote from the outlet, and by the side wall of the transfer channel remote from the outlet that is close to the outlet, intersect in a line extending on the side of the mirror plane facing the transfer channels.
