  • Patent number: 8793993
    Abstract: An energy harvesting system includes a heat engine and a component configured to be driven by operation of the heat engine. The heat engine includes a first member, a second member, a shape memory alloy material, and a tensioner. The second member is spaced from the first member. The shape memory alloy material operatively interconnects the first member and the second member. The shape memory alloy material is configured to selectively change crystallographic phase from martensite to austenite and thereby contract in response to exposure to a first temperature. The shape memory alloy material is also configured to selectively change crystallographic phase from austenite to martensite and thereby expand in response to exposure to a second temperature. The tensioner is configured to apply tension to the shape memory alloy material as the shape memory alloy material selectively expands and contracts such that the shape memory alloy material is taut.

    Abstract: Downstream expansion cylinders are associated with a combustion cylinder such that an overall surface area and displacement volume of the expansion cylinder is sufficient to lower the temperature of fluids associated with the combined engine to such an extent that a radiator can be eliminated in an associated vehicle, or other system. In a separate feature, a catalytic material is placed on surfaces which will “see” the hot exhaust gases such that catalytic conversion of impurities in the gases can be achieved within the engine itself. In yet another feature, water is recovered from a system having both a water injection expansion cylinder, and a combustion cylinder, and the recovered water is re-used for the expansion. In yet another feature, gearing is provided between the expansion cylinder and a combustion cylinder such that the output of the combined engine is optimized, and the two cylinders do not drive the crankshafts in a one-to-one fashion.

  • Patent number: 7051720
    Abstract: An engine charge air-cooling system with water fumigation for an internal combustion engine includes a charge air cooler having a housing, a heat exchanger core, an air inlet and an air outlet. The charge air cooler inlet is connected to an outlet of a compressed air source, such as a turbocharger, through a cooler intake header. The charge air cooler outlet is connected through a cooler outlet header to cylinder intake ports of the engine. The cooler intake header is adapted to receive water in a passage below the cooler inlet. Hot, compressed charge air entering the charge air cooler through the intake header mixes with water vapor formed in the header, thereby humidifying the charge air that enters the cylinders from the charge air cooler. The high, energy absorbing capability of the water molecule reduces the peak combustion temperature, thereby reducing NOx production in the combustion reaction.

    Abstract: An inert gas production system which primarily employs the exhaust gas of an engine as an inert gas source and uses a catalytic purifier to remove oxygen from the engine exhaust to produce the inert gas. The engine is preferably an internal combustion engine which operates on methane. The catalytic purification of the exhaust gas to remove oxygen is preferably performed by a packed bed catalytic purifying system including two catalyst vessels operated in series. The inert gas production system using engine exhaust can operate at a lower cost than the known membrane purification systems which produce an inert gas from air. In addition, the engine can be connected to a generator to provide an electrical energy advantage and the entire system can produce an inert gas stream containing less than 1,000 ppm of oxygen.

  • Patent number: 5944483
    Abstract: A method for wet cleaning of the nozzle rings of exhaust-gas turbocharger turbines is based on thermal shock of the contaminants, and includes the steps of injecting water in repeated, relatively small amounts, into the exhaust duct immediately upstream of the nozzle ring. A delay between injections allows the nozzle ring to reheat to operating temperature so that each water injection causes a thermal shock. An apparatus to perform the method includes water injection nozzles installed in the exhaust gas casing and a control system. The method and apparatus provide improved cleaning using less water than in known methods.

    Abstract: The invention relates to a multiple-cycle internal combustion engine having as a unit of two four-cycle cylinders operating 180.degree. apart and one two-cycle cylinder firing 90.degree. after the four-cycle cylinders fire. The four-cycle exhaust is admitted to the intake port of the two-cycle cylinder and the two-cycle cylinder ports are opened and closed in correlation with the exhaust cycle of the four-cycle cylinders so that four-cycle exhaust is admitted to the two-cycle cylinder and passes out through the outlet port thereof sweeping two-cycle exhaust out along with it. Thus, advantages are taken of the uncombusted products in the four-cycle exhaust to drive the two-cycle cylinders. At the same time, advantage is taken of the higher efficiency of four-cycle cylinders at low speeds and the higher efficiency of two-cycle cyclinders at high speeds to obtain an over all improvement in the efficiency of the engine.
