Publication number: 20080053091Abstract: A method for controlling an electrically assisted turbocharger (1,20,30,40,50) is provided. The turbocharger comprises a compressor assembly (3) having a compressor wheel for compressing a fluid to an engine (7), a turbine assembly (2) having a turbine wheel driven by an exhaust gas of the engine (7) and driving the compressor wheel (2), and an electric motor (4) for electrically driving the compressor wheel. Furthermore, at least the turbine assembly (2) comprises a variation means (10,21) for varying an operational condition of the turbine assembly (2). The method comprises the steps of judging that the actual operational condition of the engine (7) requires electrical driving of the compressor wheel, controlling said variation means (10,21) in accordance with a rotational speed of the engine (7) or in accordance with an engine load, and operating the electric motor (4) to drive the compressor wheel in accordance with a target operational condition of the engine 7.Type: ApplicationFiled: February 16, 2005Publication date: March 6, 2008Inventor: Pierre Barthelet

Publication number: 20080053093Abstract: Disclosed herein are a uniform pressure unequal surface engine and an engine for power generators using the same. The uniform pressure unequal surface engine includes a kernel cylinder having a fuel supply unit. A kernel piston is airtightly provided in the kernel cylinder and reciprocated by explosive force when fuel is burnt, thus providing rotating force to a rotating shaft. A pressure reducing cylinder is connected to the kernel cylinder via an openable exhaust gas pipe, has a relatively larger inner diameter than the kernel cylinder, and has no fuel supply unit.Type: ApplicationFiled: June 29, 2007Publication date: March 6, 2008Inventor: Chang Sun Kim

Publication number: 20080053094Abstract: A system (112) for generating electric power from solar energy is provided. The system is comprised of a solar concentrator (302) formed of an optically reflective material having a curved surface. The curved surface defines a focal center or a focal line toward which light incident on the curved surface is reflected. A thermal energy collector (310) is positioned substantially at the focal center or along the focal line. A thermal energy converter (116-1) is operatively coupled to the thermal energy collector. The thermal energy converter is configured for converting thermal energy collected by the thermal energy collector to electric power. A fuel based power generation system (128) is also provided. The fuel based power generation system is operatively connected to the thermal energy converter. The thermal energy converter provides electric power to the fuel based power generation system for generating a fuel and an oxidizer when the thermal energy collector is exposed to solar radiation.Type: ApplicationFiled: September 6, 2006Publication date: March 6, 2008Applicant: HARRIS CORPORATIONInventor: William R.
