    Abstract: A compressor(s), mounted to any combustion engine, removes exhaust. The compressor is constructed of high temperature tolerant materials. The compressor is root, vain, pinwheel or screw design driven by belt, gear, hydraulic motor, crankshaft, camshaft, or pump. This compressor removes exhaust and gases by creation of vacuum on exhaust ports or manifolds. Vacuum is stored and maintained by the motion of the driven compressor. The process starts at the crankshaft, camshaft, or pump, spinning the compressor to create vacuum on one side and boost on the other. As exhaust valves open on any combustion engine of any fuel, exhaust must leave the engine. This compressor removes that exhaust through vacuum, cooling the exhaust, expediting the revolution of the engine and improving the combustion capabilities, increasing horsepower, torque, fuel consumption, cleanliness of exhaust. Using this compressor with any conventional turbo charger will eliminate turbo lag and improve intake levels.

  • Patent number: 8448440
    Abstract: A high order of thermal efficiency is achieved in a steam engine or steam expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure, i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero and constitutes a new engine apparatus and Rankine operating cycle that can be referred to as “zero clearance with zero compression”. The steam admission valve assembly can be operated either automatically responsive to piston contact or by means of a cam shaft or electrically by means of a solenoid. A normally open exhaust valve permits residual steam to be exhausted through the piston return stroke, closed by the piston or cam then held closed by a fresh charge of steam.

  • Publication number: 20130014504
    Abstract: The invention relates to a device (1) for converting waste heat of an internal combustion machine (2) into mechanical energy. The device comprises a piston machine (3) that converts the waste heat of the internal combustion machine (2) during an OCR process into mechanical energy which can be transmitted onto a shaft (7) driven by the internal combustion machine (2). Furthermore, a variable gear (6) is provided via which the piston machine (3) transmits the mechanical energy onto the shaft (7) of the internal combustion machine (2). The variable gear (6) translates an initial rotational speed of the piston machine (3) into a rotational speed of the shaft (7) driven by the internal combustion machine (2). In this way, the ORC process can be carried out in an optimal manner.

  • Patent number: 8353159
    Abstract: An internal combustion engine has at least two double action internal combustion cylinders and a separate double action compressor cylinder. Each double action internal combustion cylinder has a multi-point ignition system for each combustion chamber for causing multiple flame fronts to cause the fuel/air mixture to burn more quickly. Furthermore, the engine has a closed heat recovery system that takes heat from the exhaust of the internal combustion cylinder system and delivers power to a crankshaft. Accordingly, the internal combustion engine has increased efficiency by minimizing friction and extracting energy from multiple sources.

    Abstract: A thermoelectric hydrogen hybrid vehicle for use with fossil fuel, the thermoelectric hydrogen hybrid vehicle has a closed loop steam engine. The steam engine's boiler is a high temperature electrolysis unit. Inside the internal combustion engines exhaust heat is directly funneled into heating the high temperature electrolysis boiler. The steam engines electrical current generated through an alternator is then stored in a battery bank and then used for sustained current for electrolysis in the high temperature electrolysis boiler. Furthermore a braking mechanism is hooked up to the alternator for electrical generation when braking to be stored in a battery bank which is then used for electrolysis.

  • Patent number: 8327654
    Abstract: An apparatus to rotate a cooling fan may employ an engine coolant radiator having a radiator inlet tank attached at an end of the radiator. The radiator inlet tank may be filled with engine coolant and transfer heat into a fan system evaporator contained inside the radiator inlet tank. The tank may contain a liquid working fluid capable of absorbing heat from the engine coolant and becoming a gaseous working fluid. A gas expander with an impeller may be employed to receive the gaseous working fluid from the fan system evaporator and impart rotation in a shaft to which the impeller of the gas expander and cooling fan is attached. A fan system condenser may receive the gaseous working fluid from the gas expander and condense the gaseous working fluid to form a liquid working fluid. A pump pumps the liquid working fluid back to the fan system evaporator.

  • Patent number: 8261715
    Abstract: Internal combustion engine has intake with compression in piston/cylinders and combustion and exhaust in a turbine. Turbine assembly includes a rotor connected to an output shaft and has variable blades pivotally mounted to rotor. The output shaft is connected to a crankshaft that is connects to the pistons to synchronizes intake and compression with combustion and exhaust. While the rotor spins centrifugal force causes the blades to swivel outwardly. The blades swivel inboard of the rotor as the space between them and the turbine housing cam contour gradually decreases. After partial compression, air enters the turbine assembly's combustion and exhaust chamber. Once full compression is attained, combustion takes place initiating a power cycle causing the turbine to rotate. When the power cycle is completed, the inner cam contour forces the blades inboard and exhaust is cleared by the subsequent variable blade, facilitating the next combustion and exhaust cycle.

  • Patent number: 8172157
    Abstract: A thermal demand priority type cogeneration system, is made operative for obtaining power output without thermal demand. When the temperature in a hot water tank 17 is low, a heat request is output from a heat request generator 42 and thereby an engine 11 is driven. When the temperature T higher than a predetermined temperature T1, a first water supply instructing unit 44 opens a valve 39 and supplies water to the tank 17 to decrease the water temperature T. When the water temperature goes down, thermal demand is generated, the engine 11 is driven according to the heat request. So as to generate thermal demand, a discharge valve 41 may be opened when the water temperature T is at the predetermined temperature or higher. A second water supply instructing unit 46 opens the valve 39 when reserved water level in the tank 17 goes down. When the valve 39 is opened, water is supplied and the water temperature goes down and thermal demand is generated.
