A thermal energy power device is disclosed. A gasification reactor is arranged on a TDC of a cylinder bulk of an internal combustion engine, wherein the gasification reactor includes gasifying plates (19) and gas holes (23). The gasifying plates are arranged with gaps on the TDC of the cylinder. The gas holes (23) are distributed evenly, in an array, or in a staggered manner on the gasifying plate (19). A cylinder head above the gasification reactor is provided with an atomizer (12). Heat absorption plates (26) are arranged inside the exhaust passage in parallel with an air flow direction. The heat absorption plates (26) absorb thermal energy of exhaust gas and transfer the thermal energy to the gasification reactor. The internal combustion engine is wrapped with an insulation layer. An added working stroke enables the temperature of the cylinder bulk to be lowered. The compression ratio is high. After being filtered by a cooler and a liquid storage tank, the discharged exhaust gas is more environmentally friendly than existing engines. After the temperature of the cylinder bulk is lowered, the discharged exhaust gas is filtered by the cooler and the liquid storage tank without noise. A working stroke is added, and the thermal energy utilization rate increases by 20%-95%. Thermal energy utilization is performed directly on the exhaust passage, and a heat dissipation water tank is not required.

The internal combustion engine can reduce pumping loss in a six-cycle internal combustion engine and increase the output.

A six-stroke rotary-vane internal combustion engine includes a stator having working chambers for intake and compression of air-fuel mixture alternating with working chambers for expansion and removing of combustion products, and a cylindrical rotor including longitudinal grooves housing blades. Side walls of all the working chambers are formed by rotating parts of the rotor, the combustion chambers are formed as hemispherical recesses on a cylindrical surface of the rotor, the working chambers of the stator are formed as cylindrical borings with axes parallel to the stator axis and evenly spaced along an inner surface of the stator, each blade consists of separate plates freely displaceable relative to each other, each plate of the blade being made of two parts movable apart in axial direction by a spring, the number of blades is a multiple of the number of the chambers for intake of air-fuel mixture.

An internal combustion engine utilizes the four-cycle process. Gas working chambers are formed using portions of a toroid, two opposing pistons, and seals at the inner gap. A cycle occur over 360 degrees of the toroid with gas ports appropriately placed. One Power Vane (PV) and one Reaction Vane (RV) connect to a central shaft with one piston assembly attached to each end of each vane. The PV produces driving torque on a central shaft through an Overrunning Clutch System (OCS). At specific angles and for controlled durations the PV and RV are slowed, stopped, held to the housing, and then accelerated and coupled to the shaft. Vane movement is controlled by gears, cam ramps, and pin mechanisms operated via multiple, independent but time-coordinated systems. The power vane has no controlled acceleration as combustion forces couple this vane to the shaft via the OCS.

A tangential force internal combustion engine invention utilizes the four cycle internal combustion engine process. Working gas chambers are formed via a torroid in the housing and two adjacent piston assemblies. Pistons, ring seals, and inner seal plate elements seal this chamber. The four gas cycles are spaced over the 360 degree torroid chamber with gas ports appropriately placed. One power vane (PV) and one reaction vane (RV) connect to a central shaft with pistons attached to each vane end. The PV produces driving torque on a central shaft through an Overrunning Clutch System (OCS). At specific angles and for controlled durations the PV and VN are slowed, stopped, held to the housing, and then accelerated and coupled to the shaft. Vane movement is controlled by gears, cam ramps, and pin mechanisms operating via three independent but time-coordinated systems. The power vane has no controlled acceleration; combustion pressure serves to immediately couple this vane to the shaft via the OCS. This immediateness and direct-coupling are thought to provide efficiency.

This invention refers to the engine-building area; in particular, to internal combustion engines with rotating parts, more specifically to a rotary-vane internal combustion engine (ICE), which can be used on water, air and land transport vehicles.

The rotary-vane ICE featuring the inlet and outlet ports and ignition plug holes with air-fuel intake and compression chambers alternating with the combustion product expansion and removal chambers, the cylindrical rotor attached to the shaft with longitudinal grooves with blades and combustion chambers arranged on the cylindrical surface of the rotor, the side walls, the front and rear end shields, in this case the side walls are arranged in the form of cylindrical borings with the axes being parallel to the stator axis and spaced evenly all over its internal surface, each blade consists of separate plates with possible mutual displacement, in this case each blade plate is made of two parts being pulled apart by a spring in axial direction and the number of blades is equal to the number of air-fuel mixture intake chambers The result to be achieved in this invention consists in simplifying the ICE design with rotary parts and in increasing its reliability and adaptability to streamlined manufacture, preventing the unburned fractions of air-fuel mixture from being emitted into atmosphere as well as ensuring that the engine can be switched over to economic run.
