摘要： A two-cycle engine is provided and includes a cylinder in which is formed a combustion chamber delimited by a reciprocating piston that via a connecting rod drives a crankshaft rotatably mounted in a crankcase that, in predetermined positions of the piston, communicates with the combustion chamber via transfer channels. The cylinder has an outlet from the combustion chamber. An intake duct leads into the crankcase for a supply of fuel, and an air duct supplies substantially fuel-free air. In the vicinity of the piston the air duct is divided into two branches that open out at air openings of a connecting flange formed on the cylinder. A cover is disposed on the connecting flange and extends over the air openings. A flow divider on the connecting flange projects beyond a plane thereof and into the cover. The flow divider divides an air flow in the air duct to the two branches.

摘要： A two-cycle engine is provided, especially in a manually-guided implement such as a power chain saw, a brush cutter, a trimmer or the like, and has a cylinder in which is formed a combustion chamber that is delimited by a reciprocating piston that, via a connecting rod, drives a crankshaft that is rotatably mounted in a crankcase. In prescribed positions of the piston, the combustion chamber is connected with the crankcase via at least two transfer channels. At least one air channel is provided that opens out at an air channel window at the cylinder in the region of the piston, and that, in prescribed positions of the piston, is connected with at least two transfer channels via a piston window formed in the piston. To achieve a good scavenging of the combustion chamber, and hence low exhaust gas values of the engine, structural features are provided on the piston window for the defined distribution of air to the transfer channels.
