VARIABLE VALVE TIMING MECHANISM AND ENGINE WITH VARIABLE VALVE TIMING MECHANISM

摘要

An engine (100) is provided with variable valve timing mechanisms (5) each comprising: an exhaust swing arm (53) swinging in response to the rotation of a camshaft (15); an intake swing arm (53) swinging in response to the rotation of the camshaft (15); and a swing shaft (51) for supporting in a swingable manner the exhaust swing arm (52) and the intake swing arm (53). In the engine (100), adjacent swing shafts (51) are connected to each other and the engine is provided with: a link mechanism (6) connected to one of the swing shafts (51); and an actuator (7) for moving the link mechanism (6). As a result of this configuration, the actuator (7) can control the pivot angle of all of the swing shafts (51) through the link mechanism (6).
