A combustion engine having a pair of two-chamber cylinders, in which double ended pistons are located and directed toward themselves oppositely by the angle 180 and compressed together via crankshafts consisting of two crank elements, which are linked rotationally backward by a spacer bearing. The compression is realized with the use of two connecting rod pairs, from which each connecting rod is linked on the one side to with one crank element, whereas the second connecting rod ends are linked to one of shafts, out of which each shaft is connected with one of pistons via a valve rod. In the middle of each cylinder's wall the outlet channel of compressed air is located as well as the outlet channel of products of combustion together with air. In the head of each cylinder and in the compartment the fuel injector, the water vapor injector and the ignition element are located.

A sparked reciprocating internal combustion two-stroke steam engine including an engine casing, a crankshaft rotatable about a crankshaft axis, a cylinder arranged inside the engine casing, a piston 1 arranged inside the cylinder to movably reciprocate along a reciprocating axis between a top dead center position distal from the crankshaft and a bottom dead center position proximal to the crankshaft and operatively connected to the crankshaft such that the reciprocating piston imparts a rotational movement to the crankshaft, a combustion chamber defined within the cylinder between the engine casing and a head of the piston opposite the crankshaft, an intake valve, an exhaust valve, a fuel injector to directly inject fuel into the combustion chamber, a water injector to directly inject water into the combustion chamber at a location below the top dead center position of the piston, and a spark plug, where the intake valve is in fluid connection with a compressed gaseous oxidizer supply configured to feed compressed gaseous oxidizer through the intake valve to the combustion chamber.

The present invention is a system to utilize slow burning fuels that contain ash with a piston that is utilized as a compressor and an expander, a pair of combustion chambers, an ash bin with a pathway on each side of the ash bin and a cylinder that houses the piston that is integral to the y-shaped pathway and produces gases that are produced by the piston emitted from the cylinder as well as a connecting rod and a crank shaft. The combustion chambers can be cone-shaped and have one or more fan blades that are made of a nonconductive material and have a positive charge. The present invention also creates a rotating body in a single combustion chamber that provides heat energy for evaporation of water and initiation of ignition of fuels that contain more than 5% water that can be connected to an ash bin to expel ash.

An internal combustion engine includes a combustion chamber. The chamber includes a body that is movable in the chamber to vary the chamber volume and contains a catalyst. First valving is operable to admit an intake gas into the chamber and second valving connected with an aqueous fluid supply system is operable to admit an aqueous fluid and a steam reforming fuel into the chamber. A controller is configured to cause the second valving to admit a aqueous fluid and an amount of the steam reforming fuel into the chamber and when a predetermined condition exists in the chamber during compression of the intake gas to absorb heat generated by the compression of the intake gas in the presence of the catalyst to promote a steam reformation process to separate hydrogen from the steam reforming fuel or the aqueous fluid.

Disclosed are two system devices for stratified injecting the recirculated exhaust gas and high-specific-heat-capacity or inert gas for clean combustion of an internal combustion engine. The former is composed of an exhaust gas recirculation system, an injection system, and a power system. The latter is composed of four parts, and a high-specific-heat-capacity gas or inert gas channel is added. Injectors can be arranged at any position in the cylinder between a top dead center and a bottom dead center of a piston in a cylinder; 1-3 layers of injectors can be arranged; and 2-6 injectors can be arranged on each layer. Gas participating in combustion enters the cylinder from two intake channels, namely, a scavenging port of the internal combustion engine and the injectors; an in-cylinder swirl ratio can be remarkably increased through kinetic energy carried by the gas; and fuel-gas mixing is promoted, and the combustion rate is increased.
