摘要： A single-shaft dual expansion internal combustion engine includes an engine block, a cylinder head and a crankshaft. First and second power pistons are moveable in first and second power cylinders and are connected to first and second crankpins of the crankshaft. An expander piston is moveable in an expander cylinder and is connected via a multi-link connecting rod assembly to a third crankpin of the crankshaft. A first balance shaft is arranged in a first longitudinal opening in the engine block, and a second balance shaft is arranged in a second longitudinal opening in the engine block. The first and second balance shafts have first and second counterweight portions, respectively, and the crankshaft has a third counterweight portion causing an imbalance in the crankshaft.

摘要： An ejector-type refrigeration cycle includes a radiator radiating heat of refrigerant discharged from a compressor, an ejector depressurizing the refrigerant cooled in the radiator, a gas-liquid separator separating gas and liquid of the refrigerant flowing out of a diffuser portion of the ejector, an evaporator disposed in a refrigerant passage connecting the gas-liquid separator and a refrigerant suction port of the ejector, and an opening-closing valve switching between a first refrigerant flow path, in which an ejection refrigerant ejected from a nozzle portion of the ejector flows out of the diffuser portion, and a second refrigerant flow path, in which the ejection refrigerant flows out of the refrigerant suction port. When a rotation rate of the compressor is lower than or equal to a standard rotation rate, the first refrigerant flow path is switched to the second refrigerant flow path.

摘要： An inlet-valve arrangement is for an external-heat engine, which includes at least one working chamber, each one having a cooperating piston. The working chamber is supplied with a working fluid via at least one controlled poppet valve. The poppet valve is arranged to open in the opposite direction to the flow direction of the working fluid. The center axis of the poppet valve is arranged perpendicularly within a deviation of ±45 degrees relative to the center axis of the piston.

摘要： A single-shaft dual expansion internal combustion engine is described, and includes an engine block including first and second power cylinders and an expander cylinder fluidly coupled through a cylinder head, and first and second power pistons that connect to respective first and second crankpins of the crankshaft. A multi-link connecting rod assembly includes a rigid main arm extending orthogonally to a longitudinal axis of the crankshaft and supporting a first pivot pin, a second pivot pin and a third pivot pin. The first pivot pin connects via a connecting rod to an expander piston reciprocating in the third cylinder. A third crankpin of the crankshaft serves as the second pivot pin and has a throw that is located 180 degrees of rotation of the crankshaft from a throw of the first crankpin. The third pivot pin connects to a swing arm connected to the engine block.

摘要： A non-compression engine having two or three variable volume mechanisms, an induction-displacer (1) and a combustion-expander (2) or an induction-displacer (1) and a combustion-expander (2) and an atmospheric-cooler (3). A working volume of gas is drawn into the induction-displacer, then displaced into the combustion-expander (2) at substantially constant volume passing through the regenerator (5). The gas in the combustor-expander (2) is further heated by combustion of a fuel then expanded to extract work. The gas is then displaced through the regenerator (5) into the atmospheric-cooler (3) at substantially constant volume, or exhaust from the regenerator at constant pressure. The gas is contracted in the atmospheric-cooler doing atmospheric work. Once the gas has equilibrated with the pressure of the atmosphere it is exhaust from the atmospheric-cooler (3).

摘要： A piston compound internal combustion engine is disclosed with an expander piston deactivation feature. A piston internal combustion engine is compounded with a secondary expander piston, where the expander piston extracts energy from the exhaust gases being expelled from the primary power pistons. The secondary expander piston can be deactivated and immobilized, or its stroke can be reduced, under low load conditions in order to reduce parasitic losses and over-expansion. Two mechanizations are disclosed for the secondary expander piston's coupling with the power pistons and crankshaft. Control strategies for activation and deactivation of the secondary expander piston are also disclosed. In addition, six-cylinder engine configurations are defined by replicating groups of two power pistons and one expander piston.

摘要： A split-cycle air hybrid engine includes a rotatable crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression (XovrC) valve and a crossover expansion (XovrE) valve defining a pressure chamber therebetween. An air reservoir is operatively connected to the crossover passage. An air reservoir valve selectively controls air flow into and out of the air reservoir. In an Air Expander and Firing (AEF) mode of the engine, the engine has a residual expansion ratio at XovrE valve closing of 15.7 to 1 or greater, and more preferably in the range of 15.7 to 1 and 40.8 to 1.

摘要： An internal combustion engine includes a cylinder that is connectable to an intake manifold through an intake valve, to an exhaust manifold through an exhaust valve, and to a transfer manifold through transfer and combustion valves. A fuel injector associated with the cylinder is adapted to provide fuel to the cylinder. During operation, the cylinder performs an intake stroke, followed by a compression stroke. A compressed charge from the cylinder passes to and is collected in the transfer manifold through the transfer valve. The cylinder is filled by a compressed charge from the transfer manifold through the combustion valve at the same time as the fuel injector provides fuel. The cylinder then undergoes combustion and exhaust strokes. In this way, cylinder operation alternates between combustor and compressor split combustion modes.
