Abstract

The two-stroke IC engine has an inlet valve formed by a rotary disc (11) whose axis (12) is not parallel to the axis (9) of the crankshaft (4), which drives the disc via a belt (6). A pulley (7) has its axis (8) parallel to the crankshaft and is belt (6)-driven via a pulley (5). The belt is a gear tooth belt with teeth laterally projecting from an edge of the belt, which teeth mesh with a gear wheel (14) arranged on the shaft (13) carrying the rotary valve disc. A roller may be in contact with the belt to ensure engagement with the gear wheel (14).
