摘要： An engine has a crankshaft. A compression piston within a compression cylinder is connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke. An expansion piston within an expansion cylinder is connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression valve and a crossover expansion valve. A runner section is in a downstream portion of the crossover passage, and a helical end section is integrally connected to the runner section. The helical end section has a funnel spiraling about a valve stem of the crossover expansion valve. The funnel forces incoming air to rotate about the valve stem prior to entering the expansion cylinder to promote turbulent kinetic energy in the cylinder air/fuel charge.

摘要： Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an internal combustion 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, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.

摘要： A high efficiency harmonic engine based on a resonantly reciprocating piston expander that extracts work from heat and pressurizes working fluid in a reciprocating piston compressor. The engine preferably includes harmonic oscillator valves capable of oscillating at a resonant frequency for controlling the flow of working fluid into and out of the expander, and also preferably includes a shunt line connecting an expansion chamber of the expander to a buffer chamber of the expander for minimizing pressure variations in the fluidic circuit of the engine. The engine is especially designed to operate with very high temperature input to the expander and very low temperature input to the compressor, to produce very high thermal conversion efficiency.

摘要： A split-cycle engine includes a crankshaft. A compression piston is received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke during a single rotation of the crankshaft. An expansion piston is received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke during a single rotation of 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. The crossover compression valve is timed to open when the pressure in the compression cylinder is less than the upstream pressure in the crossover passage at the crossover compression valve.

摘要： A piston pump comprising at least one working space, which is surrounded by a cylinder and which is adapted to be varied by a piston arranged in said cylinder, and at least one inlet valve as well as at least one outlet valve, said valves being lifting valves and being adapted to be controlled and driven by a control and drive means. In order to provide a piston pump which can be cleaned more easily and which includes the smallest possible number of dead spots, a first teaching according to the present invention suggests that, when closed, the inlet valve should be located nearer to the working space than when it is open. Alternatively, the underlying technical problem is solved according to a second solution of the present invention by the feature that the valve surface of the inlet and/or outlet valve(s) facing the working space merges without any steps with the inner surface of said working space at the closed position of the valve or of each valve.

摘要： It is disclosed a method for operating an improved internal combustion engine. An intake valve and an exhaust valve control closing and opening of respective intake and exhaust apertures. The engine includes a separating aperture between the cylinder and a separation chamber, and a controlling separating valve. The separation chamber is connected to the intake and exhaust manifolds respectively by the intake and exhaust apertures. The method includes opening the separating valve. While it is open, the exhaust valve opens and then closes, and then the intake valve opens enabling gas flow from the intake manifold to the cylinder volume through the open intake aperture, the separation chamber and the open separating aperture. The method includes closing the intake valve and closing the separating valve. Thereby, gas flow from the intake manifold stops, isolating the separation chamber from the cylinder volume and providing double isolation during compression and combustion strokes.
