060390600 | External-combustion engine type | 9 |
20130174532 | EXTERNAL-COMBUSTION, CLOSED-CYCLE THERMAL ENGINE - An external-combustion, closed-cycle thermal engine is provided with: a gas chamber, a heater, and a cooler which are closed; flow paths for connecting the gas chamber and the inlet and outlet sides of the heater; flow paths for connecting the gas chamber and the inlet and outlet sides of the cooler; on-off valves respectively provided to the flow paths on the inlet and outlet sides of the heater and of the cooler; and a means for moving a working gas. The switching of the destination of the working gas between the heater and the cooler is performed by the on-off valves, and an operation body is driven. As a result of the configuration, the volume of the heater or the cooler does not affect the efficiency of the engine, and the engine operates under various conditions. | 07-11-2013 |
20130205744 | EXTERNAL COMBUSTION ENGINE - An external combustion engine fuel that converts the expansion force of a fluid vapor to mechanical force. In some embodiments, the external combustion engine utilizes the coolant passages of an internal combustion engine block to shroud the engine block with the heat of fuel combustion when the expanding fluid vapor is directed into the engine block. | 08-15-2013 |

20140290207 | EXTERNAL COMBUSTION ENGINE - External combustion engine which comprises a first cylinder and a second cylinder, in which a first piston and a second piston are able to slide respectively. The first and second cylinder are fluidically connected with respect to each other for the passage of a heat-carrying fluid suitable to determine the cyclical movement of the first piston and the second piston. The external combustion engine also comprises a drive shaft rotating around an axis of rotation, and with which crank means are solidly associated, provided with at least a first pin and a second pin having pivoting axes parallel to each other, and also disposed distanced radially from the axis of rotation. The external combustion engine also comprises first and second kinematic connection means suitable to connect respectively the first pin and the second pin to the first piston and respectively to the second piston. The first pin and the second pin are disposed with the respective pivoting axes angularly offset so as to be angled by a desired angular amplitude equal to a first acute angle with respect to the axis of rotation. | 10-02-2014 |

20120186220 | SYSTEM FOR CONVERTING SLOW BURNING FUEL THAT CONTAIN ASH INTO ENERGY - 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. | 07-26-2012 |

20090277152 | Quasi-isobaric heat engine - One embodiment of a heat engine machine enabling a user to convert heat sources into mechanical work or compressed air. The heat engine requires solar radiation and air. The thermodynamic cycle is quasi-isobaric, and comprise positive displacement compressors | 11-12-2009 |
20110011053 | Adiabatic external combustion with low pressure positive displacement motor - The present invention relates to a method and device using an external combustion apparatus to supply large amounts of heated and pressurized combustion gases used to produce mechanical movement of a device, such as, but not limited to, a piston or a low pressure positive displacement motor. The combustion takes place in a separate pressurized combustion vessel that is supplied with organic fuel and two separate streams of compressed air, one from a lower pressure air receiver and one from a higher pressure air receiver. The combustion gases from igniting the fuel with the higher pressure air stream are accelerated and blended with the lower pressure air stream in a manner to produce a mixture of higher temperature pressurized working gas. The design includes features of regenerative cooling of the combustion vessel, improved combustion characteristics, regenerative breaking, and higher efficiency. | 01-20-2011 |
20120174558 | TOP CYCLE POWER GENERATION WITH HIGH RADIANT AND EMISSIVITY EXHAUST - The present invention generally relates to power generation methods and secondary processes requiring high radiant and emissivity homogeneous combustion to maximize production output. In one embodiment, the present invention relates to a top cycle power generator with combustion exhaust modified to have radiant flux in excess of 500 kW per square meter and emissivity greater than 0.90, and supercritical CO2 power generating cycle to maximize energy efficiency. | 07-12-2012 |
