Combustion engine having exhaust gas recirculation

Abstract: A combustion engine having an exhaust-gas-driven turbo compressor (6) is provided with a device (20) for recirculating exhaust gases to the engine, this device being connected to the exhaust system of the engine upstream of the turbo compressor (6) and being provided with a cooling device (17) for the recirculated exhaust gases The engine is provided with at least two exhaust valves (2, 3) per cylinder and has divided exhaust-gas flow, each cylinder being connected by a first exhaust valve (2) to a first exhaust collector (4), which leads to the turbine (7) in the turbo compressor, and each cylinder being connected by a second exhaust valve (3) to a second exhaust collector (5), which is connected to the exhaust system of the engine downstream of the turbine (7) The second exhaust collector (5) forms part of the device (20) for recirculating exhaust gases to the engine and is also connected to the inlet (12) of the engine

Turbine engine with intercooler in bypass air passage

Abstract: A turbine engine (20) having bypass and core passages (30 and 40), a high pressure compressor (80) for compressing air in the core passage and an intercooler (120, 220) for cooling core air (42) in the core passage prior to discharge by the high pressure compressor. The intercooler includes a plurality of heat exchange elements (140) positioned in the bypass passage through which all or a portion of the core air is transported. Heat in the core air is transferred via the heat exchange elements to the relatively cool bypass air, thereby cooling the core air and heating the bypass air. The turbine engine may have a counterflow intercooler (120), a radial flow intercooler 220 or an intercooler of other configuration. The turbine engine may have a high pressure compressor with two sections (82 and 86), with core air transported to and from the intercooler between sections, or a single section high pressure compressor, with core air transported to and from the intercooler upstream of the high pressure compressor. The turbine engine may be of turbofan, turboshaft, turboprop or other design.

Energy conversion method and system with enhanced heat engine

Abstract: An energy conversion device for converting heat to mechanical energy. The apparatus includes a heat exchanger vessel absorbing heat from an ambient or energy-rich fluid and transferring heat to a working fluid within an interior chamber of the vessel containing pressurized working gas. An isolation vessel is positioned within the interior chamber, with a gas flow loop defined between the two vessels through which the working gas flows. The isolation vessel is insulated to create a temperature differential and is pressure resistant to allow low pressures in the interior chamber to be maintained. A compressor is positioned within the isolation vessel to compress and discharge the gas into the gas flow loop. An expander is placed in the isolation vessel for converting energy of the expanding gas into a mechanical energy and for rarefying the expanded gas prior to discharge to create a lower bottom temperature or cold reservoir.
