Fluid Motor Means Is A Turbine With Output Means Mechanically Interconnected With Internal Combustion Engine Output Patents (Class 60/624)
  • Patent number: 9644545
    Abstract: A method of controlling exhaust braking in an internal combustion engine is disclosed. The engine includes an exhaust system, an exhaust pressure modulation valve, and a variable geometry turbocharger having adjustable vanes. The method includes restricting a flow of the exhaust gas through the exhaust system via a first partially-closed position of the valve. The valve's first partially-closed position increases the exhaust backpressure in the engine up to a first pressure value and generates a first stage of exhaust braking by the engine. The method also includes, following the increase of exhaust backpressure in the engine up to the first pressure value, restricting a flow of the exhaust gas through the turbocharger via closing the turbocharger's adjustable vanes. The closing of the turbocharger's adjustable vanes increases the exhaust backpressure up to a second pressure value in the exhaust system and generates a second stage of exhaust braking by the engine.

  • Patent number: 9249723
    Abstract: A power generation plant has two internal combustion engines (ICE) coupled in a compound configuration to operate electrical generators. A first ICE is a piston/cylinder engine producing high temperature and high pressure exhaust. The exhaust is coupled to the combustion air inlet of the second ICE, which is a gas turbine engine. A heat exchanger transfers heat from the exhaust of the first ICE to a bottoming cycle for additional power generation, also reducing the temperature at the turbine engine combustor. The second ICE (the gas turbine) is operated without an intake compressor, relying instead on the high pressure of the first ICE exhaust. The drive shaft of the gas turbine (or an associated generator/motor or a common shaft) operates a multi-stage turbo-compressor at the combustion air intake of the first ICE for improving engine power output without sapping exhaust energy as with a turbocharger.

    Abstract: A system for converting thermal energy from combusting fuel and air into work under an isochoric process. A reciprocating heat engine creates a cycle delay after combustion to enable sufficient time for thermal compression to occur within the working gas and within a constant volume to maximize thermal compression. A secondary engine also includes a cycle delay to maximize thermal compression of a working gas by recovering waste heat from the exhaust of the primary heat engine and converting a percentage of that heat energy into work. System cooling is accomplished under a thermodynamic cycle with heat from a liquid medium, such as water, passing through the internal combustion engine block or heat exchanger being conserved and applied to useful auxiliaries, such as residential hot water heating, baseboard heating, radiant floor heating.

  • Patent number: 8250869
    Abstract: An exhaust heat recovery apparatus includes a Stirling engine and a clutch. The Stirling engine produces motive power by recovering thermal energy from exhaust gas discharged from an internal combustion engine from which exhaust heat is recovered. The motive power produced by the Stirling engine is transmitted to an internal combustion engine transmission through the clutch and an exhaust heat recovery device transmission, and combined with the motive power produced by the internal combustion engine through the internal combustion engine transmission, and is output from an output shaft. If rapid acceleration is required, and the increase in the rotation speed of the Stirling engine therefore lags behind the increase in the rotation speed of the internal combustion engine, the clutch is released. With this configuration, reduction in the power output from the heat engine, from which exhaust heat is recovered, is restricted, and the degradation of the acceleration performance is minimized.

    Abstract: A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and a mounting point associated with the cylinder block. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to an engine, as well as oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure. The utility pedestal's fastening system is configured so as to cover a minimum amount of space of the engine surface to which the pedestal is mounted, so as to reduce the footprint of the turbocharger system.

  • Patent number: 8136740
    Abstract: A thermodynamic system that produces mechanical, electrical power, and/or fluid streams for heating or cooling. The cycle contains a combustion system that produces an energetic fluid by combustion of a fuel with an oxidant. A thermal diluent may be used in the cycle to improve performance, including but not limited to power, efficiency, economics, emissions, dynamic and off-peak load performance, and/or turbine inlet temperature (TIT) regulation and cooling heated components. The cycle preferably includes a heat recovery system and a condenser or other means to recover and recycle heat and the thermal diluent from the energetic fluid to improve the cycle thermodynamic efficiency and reduce energy conversion costs. The cycle may also include controls for temperatures, pressures, and flow rates throughout the cycle, and controls power output, efficiency, and energetic fluid composition.

  • Patent number: 8127544
    Abstract: This invention provides a compact, fuel-efficient internal combustion engine that can be used to provide rotating shaft output power to a wide variety of mobile and stationary applications. It is based on a two-stroke free-piston gas generator that implements the homogeneous charge compression ignition (HCCI) combustion principle for essentially constant-volume combustion, and it employs a variable piston stroke to maintain a high level of efficiency across a wide range of loads and speeds. A rotary device, which may be of either an aerodynamic or positive displacement type, converts the energetic gas stream to power at a rotating shaft.

  • Publication number: 20110192163
    Abstract: A waste heat recovery system of an internal combustion engine, in which the amount of regenerative energy transmitted to the internal combustion engine is increased with a simple mechanism. A controller of the waste heat recovery system of an internal combustion engine has at least determination means that makes a determination as to whether it is necessary to increase the pressure of heat-transfer media in a heat exchanger, on the basis of the pressure detected by the high-pressure sensor. When the determination means determines that it is necessary to increase the pressure in the heat exchanger, the controller causes a flow-rate regulating valve (506) to start regulating the flow rate of the heat-transfer media while leaving the pump working. The controller causes the flow-rate regulating valve to continue the regulation at least until the determination means determines that it is not necessary to increase the pressure in the heat exchanger, and then terminates the regulation.

    Abstract: An internal combustion engine comprises includes a turbo-compound and the known Föttinger-coupling is replaced by a torsion vibration damper. The Föttinger-coupling, which is used to transmit power, has high losses in power when it is necessary to have a differential rotational speed between the input side and the output side, that is, the appearance of a slip. The losses are not used in a torsion vibration damper which has at least the same quality as a Föttinger-coupling.

  • Patent number: 7950231
    Abstract: A diesel or HHCI engine has an air intake and an exhaust for products of combustion. A pair of turbochargers receive the products of combustion in a series relationship and an exhaust aftertreatment device receive the products of combustion from the downstream turbine. A power turbine receives the output from the exhaust aftertreatment device and an EGR system of the power turbine passes a selected portion of the output to a point upstream of the upstream turbocharger compressor. A device adds fuel to the aftertreatment device to regenerate the particulate filter and the power turbine recoups the additional energy. The power turbine may be used to drive accessories or the prime output of the engine.
