In one embodiment, the booster mechanism comprises an air flask which contains pressurized air or another pressurized air source that can be utilized to provide a pressure source for additional power to the exhaust turbine.Type: GrantFiled: May 26, 2010Date of Patent: March 5, 2013Assignee: The United States of America as represented by the Secretary of the NavyInventor: Paul M. Dunn

Patent number: 8381524Abstract: A piston and a reciprocating expansion engine with a piston having a piston head, a piston neck, and a piston shaft are described. The piston head has at least one groove which runs in a circumferential direction suitable for receiving a piston ring, and the piston shaft has a pin boss and, at its outer circumference, a guide surface which is suitable for guiding the piston along a cylinder inner wall. An outer diameter of the piston neck is smaller than an outer diameter of the piston head and/or of the piston shaft, and the length of the piston neck approximately corresponds to the travel of the piston in the installed state.Type: GrantFiled: August 4, 2009Date of Patent: February 26, 2013Assignee: MAN Nutzfahrzeuge Oesterreich AGInventors: Gottfried Raab, Markus Raup, Josef Klammer, Roland Kirchberger, Michael Lang

Patent number: 8261550Abstract: A power unit for an automotive vehicle includes an internal combustion engine, an electric machine electrically connected to electrical power storage arrangement, and a turbocharger comprising a first turbine located in an exhaust line of the engine. This power unit further includes a second turbine, located in an exhaust line of the engine and drivingly connected to the electric machine, and a transmission set. A first input/output of the transmission set is connected to the second turbine and a second input/output of the transmission set is connected to a crankshaft of the internal combustion engine. The transmission set has an adjustable speed reduction ratio between its first and second inputs/outputs.Type: GrantFiled: December 19, 2006Date of Patent: September 11, 2012Assignee: Renault TrucksInventor: Vincent Sartre

Patent number: 8250869Abstract: 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.Type: GrantFiled: February 28, 2007Date of Patent: August 28, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Daisaku Sawada, Shinichi Mitani, Hiroshi Yaguchi
