    摘要: A variable valve timing mechanism for an internal combustion engine wherein the camshaft is supported at one end by a combined bearing and valve body member that is detachably connected to the supporting engine body. The connection is such that fluid from the engine lubricating system can be delivered to this body and distributed by a control valve mounted in it. This simplifies machining of the engine body and permits a more compact, lower cost construction without sacrificing any function. The control valve is mounted in a bore that is accessible through the side of the cylinder head and is actuated by a servo motor mounted on the exterior of the cylinder head to provide a compact, rigid and easily serviced assembly.

    摘要: A number of embodiments of induction systems for internal combustion engines having fuel injector which spray fuel into the intake passages serving the individual combustion chambers. An arrangement is provided for injecting auxiliary air into the intake passages at atmospheric pressure. The timing and duration of air injection is varied so as to reduce pumping losses, control internal EGR, induce turbulence in the combustion chamber, control idle speed and to atomize the fuel injected by the fuel injectors, and, if desired, redirect it. Various valving and timing arrangements are disclosed whereby the duration and timing of the air injection can be controlled. In addition, embodiments are disclosed having insert pieces through which the fuel is injected and redirected by the air injected.

    摘要: A valve train for internal combustion engines utilizing an inverted bucket tappet with a pivot structure operatively disposed between the tappet and the end of the valve stem allowing the valves to be angulated with respect to each other and to the axis of the cylinder in both the transversal and the horizontal planes of the engine. Accordingly on a multi-valve engine, the valves extend radially from the associated combustion chamber to open and increase space in the center of the cylinder head for spark plugs, injectors, or pre-combustion chambers and so that the combustion chamber can be designed with a hemispherical surface, with tangentially disposed valve heads. The construction allows the use of large valves in conjunction with stronger, better-cooled valve seats and bridges. The tappets can be actuated conventionally by direct-acting overhead camshafts, by rocker arms and "T" bridges.

    摘要: A cylinder head and induction passage arrangement for a three intake valve internal combustion engine wherein the center intake passage and its porting arrangement is directed so as to augment the tumble action caused by the side valve seats and their intake passages. The construction also provides that the center intake valve will be disposed so that there will be no shrouded area in the path of flame from the spark plug so as to ensure complete combustion. The cylinder head is made in such a way that the same cylinder head may be used for either bank of an engine having angularly inclined cylinder banks through the machining of only one face thereof.
