Abstract
A valve-controlled internal combustion engine has a first valve group consisting of three inlet valves and a second valve group consisting of at least one exhaust valve for each cylinder of the internal combustion engine. The valve axis of one valve of a valve group, relative to valve axis of the other valves of the group, is arranged at a different angle from a center longitudinal plane running through a row of cylindrical bores of the internal combustion engine and is at a different distance from the center longitudinal plane. A camshaft controlling the inlet valves and a second camshaft controlling the exhaust valves or valves are arranged in the cylinder head. Rocker arms for actuating the corresponding cams of the camshafts are rotatably mounted on spindles. The valve axes are at approximately same distance from the longitudinal axis of the camshaft, and the rocker arms for the valves of a valve group are mounted alternately on either side of the camshaft at approximately the same distance from the camshaft.
