    摘要: A multi-valve engine of the type having a line of cylinders, intake and exhaust camshafts, and rocker arms for operatively connecting valves to the camshafts includes a first valve group of three valves consisting of either intake valves or exhaust valves and a second valve group consisting of the other of either intake valves or exhaust valves. Each of the valves of the first valve group is oriented such that a valve stem thereof is inclined outwardly to one side of the line of cylinders, while each of the valve of the second valve group is oriented such that a valve stem thereof inclines outwardly to an opposite side of the line of cylinders. First hydraulic lash adjuster means for a centrally-located valve out of three valves of the first valve group is positioned closer to a bore center of the cylinder than the centrally-located valve, or on a delay side in the rotational direction of the camshaft. Second and third hydraulic lash adjuster means for side-located valves of the three valves of the first valve group are positioned farther from the bore center than the side-located valves, or on a leading side in the rotational direction of the camshaft.
