Abstract
The present invention concerns a method in a two-stroke engine comprising at least one cylinder () with a reciprocating piston (), a delimited combustion space (), at least one outlet port () and an inlet port () which are both uncovered at the bottom dead center position of the piston, an actuator () which activates a valve () to open and introduce combustion air via an inlet pipe (), a control system () which controls the actuator to open the valve in order to introduce combustion air via the inlet port. The invention is characterized in that the inlet port is closed by the piston after the outlet port has been closed, thus the opposite compared to the two-stroke engines of today.
