Abstract
An engine includes a crankshaft, a camshaft being driven by the crankshaft for opening and closing intake valves, a variable valve timing mechanism (VVT) attached to one end of the camshaft, which applies torque to the camshaft so as to change the valve timing. The camshaft has an increased outside diameter at a portion adjacent to the VVT as compared to other portions that are more distant from the VVT.
