Abstract
A two-stroke engine is provided for a manually-guided implement. Formed in a cylinder is a combustion chamber that is delimited by a reciprocating piston that drives a crankshaft via a connecting rod. An outlet is provided for withdrawing exhaust gases out of the combustion chamber, and an inlet is provided for supplying fresh mixture to the combustion chamber. The inlet forms one end of a storage channel, the other end of which opens out via a window controlled by the piston into the crankcase. Via a fuel-supplying mixture channel, the storage channel is connected with a fuel supply. Combustion air is supplied to the crankcase via a crankcase inlet, with the combustion air being conveyed into the combustion chamber via a transfer channel and a transfer window. The storage channel is connected to the mixture channel via a connecting channel that is controlled by the piston.
