ABSTRACT:
A two-stroke-cycle internal combustion engine designed for crankcase scavenging has an exhaust passage, which extends from an exhaust window in the cylinder wall and which contains a control member, which is adjustable in the direction of travel of the piston to adjust the flow area of the exhaust window in dependence on one or more operational parameters of the internal combustion engine, in particular, in dependence on its speed. In order to minimize the scavenging losses and to permit the engine to combust even very lean mixtures while having a good drivability, the control member conforms to the flow lines in the exhaust passage and constitutes that edge of the exhaust window which is nearer to the crankshaft and said control member is movable to adjust said edge.
