ABSTRACT:
The invention relates to a gas-exchanging process for two-stroke internal combustion engines, and a two-stroke internal combustion engine for executing the process, in which two scavenging paths of the gas are provided, namely the known reverse scavenging as the first scavenging path, and a second supply of combustion air effected by precompression serving as the second scavenging path, wherein during the second scavenging an ignitable fuel-air mixture forms in the area of the point of ignition and, by means of the differential pressure established at the intake valve, controls the mixture as well as the quantity itself.
