Abstract (en)
An engine (3) has a cylinder block (32) mounted on a crankcase (31) and a cylinder head (33) mounted on the cylinder block (32). The cylinder head (33) has one side forming an intake port (331) and an intake valve (332) and another side forming an exhaust port (333) and an exhaust valve (334). A camshaft (336) includes an intake cam assembly (3361) and an the exhaust cam assembly (3362), which respectively drive an intake valve driving member (337) and an exhaust valve driving member (337'). The intake cam assembly (3361) includes a first intake cam (3361a) and a second intake cam (3361b). The intake valve driving member (337) includes a low lift driving member (3371) corresponding to the first intake cam (3361a) and a high lift driving member (3372) corresponding to the second intake cam (3361b). The low lift driving member (3371) and the high lift driving member (3372) form a hydraulic cylinder (338), which receives therein hydraulically operable pistons (3381, 3382).
