Variable valve lift mechanism for engine and arrangement of oil control valve

A variable valve lift mechanism for engine and arrangement of oil control valve, the engine comprising a cylinder block mounted on a crankcase and a cylinder head mounted on the cylinder block, the cylinder head forming, in one side, an intake port and an intake valve and an exhaust port and an exhaust valve on another side, a throttle valve communicating through an intake tube with the intake port, the intake valve and the exhaust valve being provided therebetween with a camshaft base, the camshaft base rotatably supporting a camshaft, the camshaft carrying therein an intake cam assembly and an exhaust cam assembly, the intake cam assembly and the exhaust cam assembly respectively driving an intake valve driving member and an exhaust valve driving member, wherein the intake cam assembly comprises a first intake cam and a second intake cam, the intake valve driving member comprising a low lift driving member corresponding to the first intake cam and a high lift driving member corresponding to the second intake cam, the low lift driving member and the high lift driving member forming therein a hydraulic cylinder, the hydraulic cylinder receiving therein hydraulically operable pistons, the oil control valve comprising a driving oil passage communicating the hydraulic cylinder, characterized in that the high lift driving member of the intake valve driving member is more close to the oil control valve than the low lift driving member and the driving oil passage of the oil control valve and the high lift driving member is shorter than the driving oil passage that the oil control valve drives the low lift driving member.
