Abstract
In the case of a high-speed, port-controlled two-stroke internal combustion engine with crankcase scavenging with at least one cylinder having in each case at least one suction duct with an inlet port, with in each case at least one outlet duct with an outlet port and with at least one scavenging duct with a transfer port, the inlet, outlet and transfer ports being arranged on the cylinder inside, the geometrical construction of the suction duct (4) and/or outlet duct (6) is such that the engine noise is reduced throughout the speed range, while increasing the engine efficiency and while simultaneously improving the specific fuel consumption.
