| 20090056331 | HIGH EFFICIENCY INTEGRATED HEAT ENGINE (HEIHE) - The present invention is a High Efficient Integrated Heat Engine, or HEIHE for short. HEIHE is a reciprocal combustion engine integrated with both compound cycle and combined cycle. HEIHE comprises twin compound cylinder structure, with the first cylinder being the primary combustion and/or expansion cylinder; the second cylinder being the secondary combustion and/or expansion cylinder. Power strokes driven by expansions of different working fluids such as air-fuel combustion products, steam and compressed air, are integrated into one engine block. Twin cylinder structure provides compound expansions of three (3) different fluids as to recover the energies that would be lost with the exhaust fluids or during braking. All of these make HEIHE work around six (6) periods with twelve (12) operation strokes. Among six (6) working periods involved, four (4) periods contain four (4) different power strokes but only one of the power strokes consumes the fuel. Thus the fuel conversion efficiency could be greatly increased, or even be doubled comparing with the conventional internal combustion engine (ICE). | 03-05-2009 |
| 20090113889 | Catalytic burner for stirling engine - The invention provides a method for transferring heat by conduction to the internal heat acceptor of an external combustion engine. Fuel and air are introduced and mixed to form an air/fuel mixture. The air/fuel mixture is directed into a catalytic reactor that is positioned substantially adjacent to the heater head. Heat is transferred via conduction from the catalytic reactor to the heater head and the catalytic reaction products are exhausted. | 05-07-2009 |

| 20100205956 | SEALED ENGINE/COMPRESSOR HOUSING COMPRISING AN ADSORPTION ELEMENT - An electrical power and heat co-generation unit typically comprising a Stirling engine includes an adsorption element within a sealed interior of the unit which is effective to remove from gas circulating within the interior of the machine hydrocarbons or other chemical species originating from within the interior of the machine from a grease, a lubricant, a retaining compound, or a sealant to reduce carburisation and/or oxidisation of internal components. The unit may also comprise within the sealed interior of the machine an atmosphere dosing fluid which is effective to react with hydrocarbons or other chemical species circulating in the interior of machine in addition to a working fluid of the machine, to produce reaction products which can be removed by the sorption element. | 08-19-2010 |
| 20100287929 | HEAT ENGINE - Heat engine with at least two cylinder-piston units, each containing an expansion fluid, which stands under a prestressing pressure and which changes its volume in the case of a change of temperature and thus moves the piston, elements for the individually controllable supply of heat to the expansion fluid of each cylinder-piston unit, and a control means controlling the heat supply elements to allow each expansion fluid to alternately heat up and cool down and thus move the pistons, wherein a common prestressing fluid acts on the pistons of all cylinder-piston units in order to exert a common prestressing pressure on the expansion fluids, the control means is fitted with a pressure gauge for the prestressing pressure, and the control means controls the heating and cooling phases of the heat supply elements in dependence on the measured prestressing pressure in order to hold the prestressing pressure within a predetermined range. | 11-18-2010 |

| 20120073284 | HOT ZONE HEAT TRANSFER STRUCTURE OF A STIRLING ENGINE - A hot zone heat transfer structure of a Stirling engine is provided. One end of a cylinder includes a heated head, with its end wall connected with a hot air pipe. The cylinder accommodates a piston. The piston has an end surface corresponding to the end wall, between which a hot zone is defined. The end wall is fitted with a protruding heat conductor towards the piston, and the end surface is fitted with a concave heat-conducting portion, enabling normal overlapping of the ends of both the heat conductor and the heat-conducting portion. The overlapping may vary with the changing locations of the piston. A flanged section is set externally onto said heat conductor towards the exterior of the end wall. The heat from the head can be transferred to the central area of the hot zone via the help of the heat conductor and heat-conducting portion. | 03-29-2012 |
| 20140020376 | OUTPUT CONTROLLER FOR STIRLING ENGINE - An output controller for a stirling engine is provided in a cooling system that causes common cooling water to flow through both the stirling engine and an internal combustion engine serving as a motive power source other than the stirling engine. The output controller for the stirling engine includes a temperature adjustment portion that adjusts a temperature of the cooling water supplied to the stirling engine. Specifically, the temperature adjustment portion includes a temperature adjustment valve capable of adjusting the temperature of the cooling water supplied to the stirling engine by switchably setting at least one of partial cooling paths and into a communication state. | 01-23-2014 |
| 20160025036 | Coolant Penetrating Cold-End Pressure Vessel - An improvement is provided to a pressurized close-cycle machine that has a cold-end pressure vessel and is of the type having a piston undergoing reciprocating linear motion within a cylinder containing a working fluid heated by conduction through a heater head by heat from an external thermal source. The improvement includes a heat exchanger for cooling the working fluid, where the heat exchanger is disposed within the cold-end pressure vessel. The heater head may be directly coupled to the cold-end pressure vessel by welding or other methods. A coolant tube is used to convey coolant through the heat exchanger. | 01-28-2016 |
