Abstract: In the apparatus for controlling a coasting air recirculation valve of the turbocharger of an internal combustion engine, the coasting air recirculation valve is arranged in the coasting air recirculation line bypassing a compressor in the intake duct, and the coasting air recirculation valve is controllable by way of the intake duct pressure on the downstream side of the throttle valve. In order to ensure defined opening and closing of the coasting air recirculation valve, an additional control pressure, with which the coasting air recirculation valve can be opened independently of the intake duct pressure, can be delivered to the coasting air recirculation valve.

Abstract: An exhaust gas recirculation (EGR) enhancement system for a turbocharged internal combustion engine includes a throttle valve arranged in the exhaust duct of the engine, downstream of the EGR system. The throttle valve is controlled in response to engine load and engine speed to selectively provide back pressure upstream of the throttle valve to selectively drive an EGR exhaust flow through an EGR duct to the intake manifold. An embodiment of the EGR system includes a cooler that lowers the temperature of the EGR exhaust flow to provide better reductions in nitric oxide emissions. The turbine is equipped to allow excess pressure to be released through a wastegate duct arranged in fluid parallel with the exhaust turbine, thereby allowing for higher power and higher speeds.

Abstract: A turbocharger, particularly suitable for use in an internal combustion engine, recirculates exhaust gas from the turbine to an interstage duct area between two compressor wheels of a multi-stage compressor. The turbocharger includes a rotatable shaft; a turbine including a turbine wheel carried by the shaft; and a multi-stage compressor. The multi-stage compressor includes a first compressor wheel carried by the shaft, an axially extending first inlet associated with the first compressor wheel, and a radially extending first outlet associated with the compressor wheel. A second compressor wheel carried by the shaft includes an axially extending second inlet associated with the second compressor wheel, and a radially extending second outlet associated with the second compressor wheel. An interstage duct fluidly interconnects in series the first outlet associated with the first compressor wheel and a second inlet associated with the second compressor wheel. An exhaust gas recirculation duct fluidly interconnects the turbine with the interstage duct. A valve is positioned within the exhaust gas recirculation duct.

Abstract: In order to increase the operating reliability by means of simple measures in a method for operating a supercharged internal combustion engine which has two exhaust-gas turbochargers arranged in parallel, in each case only one exhaust-gas turbocharger is actively put into operation, the actual value of a characteristic quantity is measured and is compared with a predeterminable desired value, and, in the event of an inadmissible deviation of the actual value from the desired value, a change-over is made between the exhaust-gas turbochargers by means of the control signal.

Abstract: This invention relates to configuration of at least two exhaust gas turbochargers on an internal combustion engine with a plurality of cylinders, in particular in a motor vehicle, in which the two turbine housings are connected to the exhaust gas system of the internal combustion engine and are immediately adjacent to each other and one turbine is always connected to one compressor by means of a drive shaft, the drive shafts being rotatably mounted in corresponding bearing housings. In order to prepare a design which is advantageous from the viewpoint of structure and production technology, it is proposed that the turbine housings are oriented such that the drive shafts be positioned at least approximately in alignment with each other and that the bearing housings be connected to the turbine housings on both sides.

Abstract: The present invention relates to an electronically driven pressure boosting system that is used to boost the torque output of an internal combustion engine. The system comprises an electrically driven pressure charging device, an electrical supply system for providing electrical power to drive the pressure charging device including a battery and an engine-driven battery recharger, and an electronic control system for controlling the operation of the pressure charging device and the electrical supply system. The electronic control system determines one or more allowable operating limits to the operation of the pressure charging device based on the state of the electrical supply system, and drives the pressure charging device using the engine-driven battery recharger when the state of the electrical supply system is within an acceptable range. The engine control system then isolates at least partially the battery from the engine-driven battery recharger and drive the pressure charging device using the battery when the state of the electrical supply system is not within an acceptable range.

Abstract: Valve device for evacuation of a gaseous medium under overpressure from a space (3) includes a valve housing (1a) with an opening (2) to the space (3); a valve disc (6) cooperating with a valve spindle (8), sealing the opening in the closed position of the valve and, disposed in a cylinder (12), a control plunger (13) which, via a spring, biases the spindle and thus the valve disc towards the closed position. When pressure medium with a predetermined control pressure is supplied, the plunger is lifted from the valve spindle, whereupon the force from a balancing spring (11) and the medium pressure in the space (3) act in the valve opening direction, while the force of the control pressure acting on the spindle (8) loads the valve disc in the closing direction.

Abstract: The present invention relates to a crank case ventilation system for an internal combustion engine that has a two-stage air charge boosting system. An air inlet system supplies the engine with air that may be pressurised by an upstream supercharger and a downstream turbocharger in series. A crank case evacuation system draws crank case gasses from a crank case and introduces said gasses into the air inlet system, through either a first conduit or a second conduit, depending on the setting of a pressure-regulated control valve. The first conduit is used to introduce said gasses upstream of the first boost stage when this stage is operational, and when the first boost stage is not operational, the second conduit is used to introduce said gasses downstream of the first boost stage and upstream of the second boost stage.

Abstract: An ECU preliminarily obtains a target supercharging pressure determined based on an engine rotational speed and an engine load, and stores the target supercharging pressure value. The ECU commands a flow passage area changing unit to set an exhaust gas flow passage area to the maximum flow passage area or the minimum flow passage area, and judges the abnormality of a supercharger by comparing supercharging pressure detected by a supercharging pressure sensor and the stored target supercharging pressure.
