Abstract
A crankcase (1) of a two-stroke engine comprising at least one inlet port (10,11) opening into a crankcase chamber (3) and at least one crankshaft member (4,5) rotatable within the crankshaft chamber (3). The opening and closing of the at least one inlet port (10,11) for allowing or blocking the admission of an air-fuel mixture to the crankcase chamber is controller by the shape of the peripheral surface of the or each crankshaft member (4,5) which rotates in front of the or each inlet port. The invention also relates to a two-stroke engine provided with such a crankcase.
