Title: FOUR-STROKE INTERNAL COMBUSTION ENGINE THERETO RELATED VEHICLE AND METHOD
Abstract:
Herein a four-stroke internal combustion engine (2) is disclosed. A camshaft (25) and a crankshaft (20) if the engine (2) are synchronised to rotate at a same rotational speed. A first linkage arrangement (40) is configured to change the motion of an exhaust valve head (30). A second linkage arrangement (41) is configured to change the motion of the intake valve head (31). A control unit (54) is configured for controlling the first linkage arrangement (40) to selectively prevent the motion of the exhaust valve head (30) and for controlling the second linkage arrangement (41) to selectively prevent the motion of the intake valve head (29).
