Abstract
A valve drive mechanism for a DOHC engine which leaves sufficient installation space for a functional part (,) to be located at a central portion of each of cylinder bores (,) even if each cylinder bore is relatively small. When viewed from the top, two intake valves (,) are linearly arranged in parallel to the longitudinal center line of the engine and two exhaust valves (,) are linearly arranged on the opposite side. The center line (,) of an intake camshaft (,) is offset from the mutual center line of the linearly arranged intake valves in a transverse direction of the engine to an outside direction of the associated cylinder bore such that the intake camshaft center line (,) is apart from the longitudinal center line of the engine and the exhaust camshaft center line (,) is offset in the opposite transverse direction from the mutual center line (,) of the linearly arranged exhaust valves (,), with the parallel relationship between the intake and exhaust camshafts being maintained. The distance between the intake camshaft and exhaust camshaft is therefore enlarged as compared with a conventional arrangement.
