<p>In an engine having three or more inlet valves (5), an inlet camshaft (10) is disposed on a valve seat (5c) side from the phantom axis (12) on which the axes of the inlet valves (5) cross. Engagement is achieved with a slight offset (x) between the inlet camshaft (10) and each lifter (9) driven by the inlet camshaft (10). The inlet valves (5) are driven by rotation of the inlet camshaft (10) through the lifters (9). Such a reduction of height and width of a cylinder is provided.</p> |
