Abstract
A variable valve timing mechanism-equipped engine is provided which allows a mount installing section and a hydraulic control valve of a variable valve timing mechanism to be positioned in a chain case without limitation of positioning of accessories such as a water pump, air conditioning compressor, power steering oil pump and alternator, and which simplifies an operating oil passage for the hydraulic control valve. In the variable valve timing mechanism-equipped engine, a mount installing section is positioned below an actuator cover section and is offset toward one side with respect to a cylinder axis, and intake- and 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- and the exhaust-side hydraulic control valves overlapping one another.
