20110232280TURBOCHARGER DIVERTER VALVE - A piston actuated diverter valve is employed to recirculate air through a turbocharger compressor when the device is not activated in an engine. An example diverter valve includes a housing forming a cylinder. A piston is arranged within the cylinder and an aperture passes from an exterior of the housing into the cylinder. A conduit is connected to the cylinder such that a pressurized fluid in the conduit acts to move the piston within the cylinder to cover and/or uncover the aperture.09-29-2011
20130125543HEATING APPARATUS FOR INTERNAL COMBUSTION ENGINE EXHAUST AFTERTREATMENT - A heating apparatus for engine exhaust includes a housing having an inlet for connection in an exhaust gas conduit to receive exhaust gas and an outlet for connection in an exhaust gas conduit to discharge exhaust gas, the housing defining an interior space, a burner unit mounted in the housing for combustion of a fuel in the interior space, and, a turbocompressor, including a turbine having an inlet to receive exhaust gas to drive the turbine and an outlet connected to the housing to discharge exhaust gas and a compressor driven by the turbine and having an inlet to receive ambient air and an outlet connect to deliver compressed air to the burner. The turbocompressor may be mounted on the housing upstream of the burner unit.05-23-2013
20130139505DEVICE FOR EXHAUST-GAS TREATMENT NEAR AN ENGINE AND MOTOR VEHICLE HAVING THE DEVICE - A device for exhaust-gas treatment near an engine includes an annular structure and a guide structure disposed in an exhaust line. An inner wall forms an inner flow passage and an outer flow passage in the annular structure. The inner wall and the guide structure form a gap in such a way that only a limited secondary flow of the exhaust gas is conducted through the inner flow passage. A motor vehicle having the device is also provided.06-06-2013
20080202117Element of an Exhaust Line Provided With a Turbocompressor - This exhaust line element for a supercharged heat engine comprises an exhaust manifold (08-28-2008
20080196407Method and an Arrangement in Connection with a Turbocharged Piston Engine - The invention relates to a method and an arrangement in connection with a piston engine provided with a turbocompressor. In the method, combustion air from the engine is pressurized by the compressor of the turbocompressor, pressurized combustion air is humidified, fuel is combusted in the cylinder of the engine by means of combustion air and the exhaust gases generated during the combustion are conveyed by means of combustion air to the turbine of the turbocompressor. A partial flow is separated from the pressurized combustion air flow, conveyed past the engine and combined with the exhaust gas flow going to the turbine.08-21-2008
20100307151COMPRESSOR AND METHOD FOR SERVICING - A compressor has a diffuser section with one or more detachable wall portions that define a diffuser surface. The wall portions may be detachably connected to an intermediate portion of the compressor housing between the inlet and outlet and/or to the bearing housing of a turbocharger to which the compressor housing is connected. The diffuser wall portions can be easily detached once the compressor housing is removed so as to allow cleaning of deposits or simple replacement. This provides for easy servicing to avoid the compressor performance being compromised by a built up of deposits and particulates on the diffuser surfaces that is a particular problem in turbochargers that receive recirculated crank case ventilation gases from the engine.12-09-2010
20120272645Reciprocating combustion engine - Methods and apparatus are described for a reciprocating combustion engine. A method includes operating a dual-piston engine including introducing a gas into a pair of combustion chambers; introducing a fuel into the pair of combustion chambers; compressing the gas; combusting the gas and the fuel; and exhausting combusted gases. Each of the pistons drives a reciprocating crankshaft that protrudes through a cylinder wall and cooperatively rotate a pair of rotors by engaging substantially sinusoidal cam tracks on the rotors. An apparatus includes a cam driven, concentric drive rotary-valve dual-piston engine.11-01-2012
