Abstract: An internal combustion engine includes a valve operating device operatively connected to a pair of intake valves and capable of opening and closing one of the intake valves in accordance with the operating condition of the engine and opening and closing the other intake valve in a small lift amount, thereby producing a deflection of the intake air drawn into the combustion chamber, and a fuel injection valve for injecting a fuel toward the pair of intake valve bores that are independently opened and closed by the intake valves, respectively. The timing of the opening and closing of the intake valve that is opened and closed only in the small lift amount is set at a time point such that the lift amount is maximized in the first half of the intake stroke of the piston. This promotes the atomization of the fuel which is being drawn in with the intake air by the opening of the intake valve opened and closed in the small lift amount, and to enhance the combustibility in the combustion chamber.

Abstract: A general electro-rheological valve is disclosed used in controlling the flow of fluids in a variety of applications. The valve comprises an inlet in communication with a fluid source, an outlet for transporting the fluid out of said valve, and an oscillating valve member for opening and closing off said inlet. The valve member has a cavity containing an electro-rheological fluid, a perforated electrode member emersed in the electro-rheological fluid within the cavity, and means for electrifying the perforated electrode member such that the electro-rheological fluid within the electrode solidifies, thereby locking the position of the valve member relative to the electrode. In this manner, the valve member, which oscillates with respect to the perforated electrode member, can be frozen in an open, closed, or intermediate position with respect to the inlet. The valve member thereby controls the level of fluid flow through the valve.

Abstract: An actuating apparatus, which can be used to perform variable valve timing of the intake or exhaust valves of an internal combustion engine, includes a hollow shaft with at least one slot defined through a cylindrical wall. A movable cam member is disposed to project through the slot and is rotatable relative to the hollow shaft in a channel defined in the interior surface of the hollow shaft. A base circle band extends circumferentially around the outer surface of the hollow shaft between the endwalls of the slot. The exterior surface of the hollow shaft can define grooves which receive front or back ear members of the cam member. The exterior surface of the hollow shaft also can define recesses, which in some embodiments have bottom surfaces and in other embodiments have partial bottom surfaces or no bottom surface. The recesses can receive tongue members formed on the cam member. The cam member can be engaged by a cam follower that has a roller to engage the cam surface. When the length of the roller exceeds the width of the cam surface, base circle arcuate sections can be provided on the exterior surface of the hollow shaft to carry the roller across the exposed portion of the slot that exists between the endwall of the slot and the free end of the cam member. An inner shaft extends through an opening defined transversely through the cam member and nonrotatably engages same. The nose portion of the cam member can be defined by a rotatable roller. Twin cam members having identical cam surface profiles can be disposed side-by-side, with one cam member projecting through the slot and the other cam member secured to the outer surface of the hollow shaft. A single follower such as a tappet defining a circular cylindrical surface can be provided to engage both cam members and can be held nonrotatably.

Abstract: An engine valve driving device includes a rocker arm attached at one end to a valve stem and carrying at its opposite end a roller which engages the surfaces of a stepped cam plate. The cam plate has a horizontal surface which includes upper and lower portions joined by an inclined portion so that horizontal reciprocating motion operates the rocker arm and the connected valve. The cam plate is connected to a rotary cam crank shaft so that rotation of the crank shaft produces linear reciprocating motion in the cam plate. The connection between the cam shaft and the cam plate is adjustable, as by a hydraulic cylinder, to vary the gap between the cam plate and the cam shaft and to thereby vary the timing of the motion of the valve with respect to the rotation of the cam shaft. In an alternative form, the connection between the cam and the cam shaft may be a pivotal lever, with the pivot point of the lever being movable to provide timing adjustment.

Abstract: A self-adjusting variable duration hydraulic lifter utilizes two plungers within the cylindrical lifter body which move together to shorten the overall top-to-bottom length of the internal plunger pair during the valve opening cycle of the engine at low RPM's to improve engine performance. A pre-established gap between the two plungers establishes the bleed down amount for the lifter at low RPM, and the gap is self-adjusting in that it will remain the same over the lifetime of the engine despite changes in the overall length of the valve train and heat compensation effected by the hydraulic mechanism effected by the lifter.

Abstract: A method is provided for improving the performance of an internal combustion engine, comprising the steps of inducting a charge of fluid into the combustion chamber of the engine, holding the intake valve of the combustion chamber open during a portion of the compression stroke of the piston in the combustion chamber, expelling a portion of the inducted charge from the combustion chamber by movement of the piston in its compression stroke while the intake valve is held open, preventing the expelled portion of the inducted charge from communicating with the atmosphere by providing a check valve between the induction manifold and the atmosphere, the check valve only permitting flow in the direction from the atmosphere into the induction manifold; and closing the intake valve during the remainder of the compression stroke and after the portion of the induction charge is expelled.
