摘要： A split cycle internal combustion engine includes a combustion cylinder accommodating a combustion piston and a compression cylinder accommodating a compression piston. The engine also includes a controller arranged to receive an indication of a parameter associated with the combustion cylinder and/or a fluid associated therewith and to control an exhaust valve of the combustion cylinder in dependence on the indicated parameter to cause the exhaust valve to close during the return stroke of the combustion piston, before the combustion piston has reached its top dead centre position (TDC), when the indicated parameter is less than a target value for the parameter; and close on completion of the return stroke of the combustion piston, as the combustion piston reaches its top dead centre position (TDC), when the indicated parameter is equal to or greater than the target value for the parameter.

摘要： A compressor like unit which can be attached to an internal combustion engine controls the amount of the air mass that passes through its cylinder to the internal combustion engine based on the engine load condition requirement at a given time replacing this way the throttle device function and creating thus a throttle-less internal combustion engine. The compressor can be built in different ways and can function as one or multiple units attached directly to the engine through its crankshaft or a gear box or by other means.

摘要： A two-stroke reciprocating piston engine. The engine principally consists of an expansion cylinder and a compression cylinder, and an expansion chamber and a combustion chamber. When pistons of the expansion cylinder and compression cylinder move from a bottom dead center to a top dead center, gas in the expansion cylinder is compressed in the expansion chamber, gas in the compression cylinder is compressed in the combustion chamber, a water spray nozzle sprays water towards the high temperature and high pressure gas in the expansion chamber, and when the water encounters the high temperature and high pressure gas, the water is rapidly vaporized. At the same time, an oil spray nozzle sprays a fuel into the combustion chamber, a spark from a spark plug ignites the combustible gas of the combustion chamber, the high temperature and high pressure gas produced by the combustion pushes open a valve of the combustion chamber.

摘要： A split-cycle engine includes a compression cylinder having a first volume for a first working fluid and a second volume for a second working fluid, the first volume and second volume being separated by the compression piston, an expansion cylinder having a first volume for the first working fluid and a second volume for the second working fluid, the first volume and second volume being separated by the expansion piston, and a fluid coupling between the second volume of the compression cylinder and the second volume of the expansion cylinder, wherein the two second volumes and the fluid coupling provide a closed volume for the second working fluid, wherein the fluid coupling includes a regenerator arranged such that the two second volumes are thermally decoupled.

摘要： A split-cycle engine includes: a first cylinder housing a first piston, wherein the first piston performs an intake stroke and a compression stroke, but does not perform an exhaust stroke; a second cylinder housing a second piston, wherein the second piston performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke; and a valve chamber housing a valve, the valve comprising an internal chamber that selectively fluidly couples to the first and second cylinders, wherein the valve and internal chamber move within the valve chamber and relative to the first and second cylinders.

摘要： An opposed-piston engine that forms an inviscid layer between pistons and the respective cylinder walls. In an aspect, the opposed-piston engine utilizes a Scotch yoke assembly that includes rigidly connected opposed combustion pistons. In an aspect, the Scotch yoke assembly is configured to transfer power from the combustion pistons to a crankshaft assembly. In an aspect, the crankshaft assembly can be configured to have dual flywheels that are internal to the engine, and can be configured to assist with an exhaust system, a detonation system, and/or a lubrication system.

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.
