    Abstract: Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber or heat exchanger.

    Abstract: In a control apparatus for an internal combustion engine having a valve timing control means controlling the timing opening and closing of an intake valve disposed in an intake port communicating with a cylinder of the internal combustion engine, when the internal combustion engine is being started from a cold condition, multi-stroke operation is set, in which one combustion cycle of the internal combustion engine includes two or more intake and compression strokes, formed by a first intake stroke and the first compression stroke and a second intake stroke and compression stroke, followed by a combustion stroke and an exhaust stroke. The valve timing control means controls a lift of the intake valve during the first intake stroke and the first compression stroke to a low lift amount, which is smaller than the normal lift amount required for intake of a requested intake air amount, and controls the lift of the intake valve in a second intake and a second compression stroke to the normal lift amount.

    Abstract: A hybrid internal combustion engine having a cylinder, a piston disposed within the cylinder, the piston constructed and arranged to reciprocate within the cylinder, and a combustion chamber defined by the cylinder and the top of the piston. The hybrid internal combustion engine also includes an exhaust manifold and a heat exchanger disposed within the exhaust manifold. A pump disposed between the heat exchanger and a fluid reservoir is provided to deliver fluid from the reservoir to the heat exchanger, whereby the fluid in the heat exchanger is heated and turned into high pressure gas (HPG) when the combustion gases are exhausted from the combustion chamber via the exhaust manifold. The resulting HPG may then be introduced into the combustion chamber to provide a HPG power stroke.

    Abstract: An eight-stroke engine cycle may include a first stroke forming an intake stroke and including opening an intake valve and providing a first fuel mass to the combustion chamber. The second stroke may form a first compression stroke and the third stroke may form a first expansion stroke including a first power stroke. The fourth and sixth strokes may form a second and third compression strokes and the fifth and seventh strokes may form a second and third expansion strokes. A second fuel mass may be provided to the combustion chamber during the fourth or sixth stroke. The intake valve may be in a closed position during the second and third expansion strokes and an exhaust valve in communication with the combustion chamber may be in a closed position during the second and third compression strokes. The eighth stroke may form an exhaust stroke including opening the exhaust valve.
