ABSTRACT:
The invention relates to a two-stroke internal combustion engine with longitudinal scavenging, with at least one piston reciprocating in a cylinder, with at least one exhaust valve disposed in the cylinder head floor and with at least one intake slot per cylinder which can be passed by a control edge of the piston, with at least one exhaust gas recirculation conduit for the recirculation of exhaust gas into the combustion chamber and at least one exhaust gas recirculation valve for controlling the recirculated exhaust gas quantity. In order to enable exhaust gas recirculation in the simplest possible way, it is provided that the exhaust gas recirculation conduit starts out directly from the combustion chamber and the exhaust gas recirculation valve is arranged as a stroke valve which is disposed in the region of the entrance of the exhaust gas recirculation conduit into the cylinder head floor.
