Patent ID: 7546824

Claim:
A variable valve timing mechanism-equipped engine having a crankshaft rotatably supported in a cylinder block of the engine, a pair of intake and exhaust camshafts rotatably supported on a cylinder head mounted on the upperside of the cylinder block, a timing chain entrained around a crankshaft sprocket and intake and exhaust camshaft sprockets, the crankshaft sprocket being attached to the crankshaft, the intake and the exhaust camshaft sprockets being attached to the intake and the exhaust camshafts, intake-side and exhaust-side actuators attached to the intake and the exhaust camshafts for changing the rotational phase of the intake and the exhaust camshafts with respect to the crankshaft, the intake-side and the exhaust-side actuators being operated by the operating oil supplied from intake-side and exhaust-side hydraulic control valves respectively, a chain case, when viewing the engine from an axial direction of the crankshaft, having transverse opposite ends joined to the cylinder block and the cylinder head and having an upper end joined to the cylinder head cover for covering the timing chain, an actuator cover section formed in the chain case to be expanded in the axial direction of the crankshaft along a mating surface with the cylinder head cover for covering the intake-side and the exhaust-side actuators, a mount installing section expanded in the axial direction of the crankshaft to be disposed below the actuator cover section for connecting an engine mount, and accessories arranged on transverse opposite sides of the chain case to overlap along a cylinder axis direction, the accessories being driven through a belt on a crankshaft pulley attached to the crankshaft, characterized in that the mount installing section is positioned below the actuator cover section and is offset toward one side with respect to the cylinder axis, and the intake-side and the exhaust-side hydraulic control valves are disposed sideward of the mount installing section with axes inclined toward a direction perpendicular to the crankshaft axis, the intake-side and the exhaust-side hydraulic control valves overlapping one another.
