Abstract: Multiple intake valves operatively associated in a common combustion chamber are advantageous in that the design achieves high output for an internal combustion engine. The subject modified cylinder head utilizes the advantages available in a multiple intake valve system, but further enhances the design by reducing heat rejection. In the subject modified cylinder head, three intake valves (38,40,42) having corresponding intake valve ports (26,28,30) and one exhaust valve (68) having an exhaust valve port (66) are operatively associated in a common combustion chamber. A reduction in heat rejection is achieved through a relationship between the cross-sectional areas of the intake and exhaust valve ports (26,28,30,66). The intake valve ports (26,28,30) are constructed so that their cross-sectional area is larger than about 69% of the combined cross-sectional area of the intake and the exhaust ports (26,28,30,66).

Abstract: A lubrication arrangement for an engine and more particularly to an arrangement for lubricating the valve train of an engine. The valve train includes a cylinder head that journals an intake and an exhaust camshaft through bearings formed in the cylinder head and the cam cover. Hydraulic lash adjusters are associated with each of the camshafts and there are more intake adjusters than exhaust adjusters. An arrangement is provided for delivering lubricant to the lash adjusters and the camshaft journals which includes a passageway formed in the cam cover. Lubricant is delivered to the cylinder head in proximity to the intake adjusters so that the intake adjusters and the exhaust adjusters will receive lubricant at substantially the same pressure.

Abstract: A timing system for controlling, by means of a single overhead camshaft, three adjacent, homologous valves of an internal combustion engine cylinder; each valve having a tappet located between the valve stem and a respective control cam on the camshaft. The valve stems are arranged with their axes shifted laterally, and alternately on opposite sides, in relation to a plane including the axes of the tappets, so as to define a first eccentricity between each valve stem and respective tappet in a plane perpendicular to the camshaft axis. The intermediate valve item is aligned with the axis of the respective tappet in the first plane. In a plane perpendicular to the above plane the other two valve stems are both shifted laterally towards the intermediate valve stem, so as to define, with the respective tappets, a second eccentricity perpendicular to the first. The tappets may thus be arranged side by side and aligned centrally along the camshaft axis.

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.

Abstract: A multiple valve engine and more particularly an improved combustion chamber and valve arrangement for such an engine that permits high compression ratios, good breathing and a smooth combustion chamber. There are provided three intake valves and two exhaust valves. The center intake valve is supported so that it reciprocates about an axis that lies in a plane containing the cylinder bore axis. The other valves are all inclined to each other so that adjacent edges between the valves will all lie in a common plane that extends perpendicularly to the cylinder bore axis to provide a smooth combustion chamber configuration. In addition, tapered cam lobes on the camshafts operate the angularly disposed valves. These tapered cam lobes have heel diameters that are larger than the adjacent bearing surfaces of the cams so that the cam lobes may be conveniently formed by grinding without damaging the bearing surfaces.

Abstract: The axes of the three inlet valves associated with each cylinder of an internal combustion engine are parallel to each other. The valves are all operated by the same camshaft which acts on the three valves from above through three interposed rocker arms. The rocker arm of the valve which is in the intermediate position is in a reverse orientation relative to the other two rocker arms.
