Abstract

A two-stroke engine is provided that has a cylinder, in which a combustion chamber is formed, and a piston, which delimits the combustion chamber and which drives a crankshaft rotatably mounted in a crankcase. The piston controls an inlet window for fuel/air mixture into the crankcase interior. A flow guide element is arranged in the crankcase interior which extends adjacent to the inlet window. The flow guide element has at least one first inflow surface by which at least a first partial quantity of the fuel/air mixture flowing in through the inlet window is diverted in the direction of the crankshaft.
