A power system including a variable volume combustion chamber for a two-stroke engine having a controlled exhaust port, a fuel injector to the combustion chamber and an oxygen injector to the combustion chamber. The oxygen injector provides repeated oxygen injection pulses to complete a charge. The controlled exhaust port includes an oscillating rotatably mounted valve. A source of pressurized concentrated oxygen to the oxygen injector is in a closed case having a ceramic fiber membrane. An air inlet and a waste outlet are in communication with a first side of the ceramic fiber membrane. An oxygen outlet is in communication with a second side of the ceramic fiber Ionic transport membrane. The case has a heat transfer surface in communication with the controlled exhaust port from the combustion chamber.

A plug valve with adjustable actuation phases for controlling a flow rate by means of plug axial movement includes a power disk, a bearing, an inner spline, an outer spline, a valve stem, a pushing ring, a pushing fork, a plug body and a valve body. The plug body, the valve stem, the pushing ring and the outer spline are integrally formed, and are in spline connection with the power disk and the inner spline. The plug body has a special-shaped through hole in which a left portion thereof is narrow and a right portion thereof is wide. The valve body has a radial valve through hole, and the valve through hole corresponds to the plug special-shaped through hole provided at the same axial position segment, so that an actuating member for controlling actuation of a passageway is formed.

A mixing valve of an exhaust-gas recirculation device of an internal combustion engine of a motor vehicle includes an intake flap and an exhaust-gas flap coupled rigidly to one another via a coupling rod. During driving of the exhaust-gas flap, the intake flap is first pivoted in the opposite direction via the coupling rod. The exhaust-gas flap and intake flap are pivoted in the same direction only above a provided pivoting angle.

An invention is provided for a new and novel intake/exhaust device for an internal combustion engine. A rotating cylinder having an intake/exhaust port penetrating the outer surface of the rotating cylinder and meet at an axis of rotation and have a connective relationship which allows fluid to flow easily. The rotating cylinder when used in a 4-stroke engine aligns the intake port with the combustion chamber, and when rotated will align the exhaust port with the combustion chamber each at the correct time. This novel invention overcomes the limitations of current valve trains by only using rotation, and not by using rotation and linear motion to activate valves thereby allowing the engine to attain much greater RPMs.

Apparatus for controlling valve timing in an internal combustion engine locates a first valve port in a first side of the engine cylinder and a second valve port in a second side of the engine cylinder. A first rotating valve disc and a second rotating valve disc are respectively disposed next to the first and second valve port. Each rotating valve disc includes a valve port. Each disc rotates in synchronism with the crankshaft to align its' port with the respective first and second valve ports. A variety of intake devices coupled to the first rotating valve disc control intake air flow into the engine cylinder, and a variety of exhaust devices coupled to the second rotating valve disc control exhaust gas flow from the engine cylinder.

An internal combustion engine inducts no air from outside atmosphere and it discharges no gas into outside environment. The engine receives hydrocarbon fuel and oxygen, and its combustion gas consists mostly of carbon dioxide and water vapor. Carbon dioxide is captured, stored and subsequently sequestered by using it with water to create a hydrocarbon fuel that can be supplied back to the engine. In that way, the engine fuel is repeatedly regenerated and reused, and the engine operates in a carbon neutral mode of operation. Some of the combustion gas is used as a diluent gas in the engine. High specific heat and high density of that gas permit operation in high-efficiency overexpanded cycle without an increase in the engine size. Various methods of the engine control and operation are described, including methods to reduce pumping loss. Various modes of in-cylinder diluent gas formation are considered.
