| 20090193790 | Method For The Regeneration Of A Particle Filter Installed In The Exhaust Gas Train Of A Vehicular Diesel Engine - A method for regenerating a soot-laden particle filter in the exhaust gas train of a diesel engine in a vehicle, wherein the engine is equipped with a fuel injection system having an injection valve for each cylinder and an exhaust braking device including a butterfly valve in the exhaust gas train upstream of the particle filter. An exhaust braking phase is initiated by closing the butterfly valve, thereby causing hot exhaust gas to be compressed upstream of the butterfly valve. Regeneration of the particle filter is then initiated by injecting diesel fuel into the cylinders substantially after the respective pistons pass top dead center, and allowing the hot exhaust gas mixture containing unburned fuel and air to flow past the butterfly valve so that the mixture ignites the soot and then supports combustion of the soot, thereby regenerating the particle filter. | 08-06-2009 |

The drive unit has an internal combustion engine in operative connection with a driven shaft and a reciprocating piston expansion engine in an operative connection with a crankshaft. The driven shaft is mechanically connected to the crankshaft by a clutch in such a way that torque is transmitted from the crankshaft to the driveshaft. The reciprocating piston expansion engine has at least one cylinder, and a fluid is guided from a fluid supply into an interior of the at least one cylinder at least occasionally via an inlet valve and a bypass valve which is arranged in parallel with the inlet valve. | 11-05-2009 |
| 20100083659 | Reciprocating Expansion Engine and Piston of a Reciprocating Expansion Engine - 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. | 04-08-2010 |
| 20100139626 | Drive Unit with Cooling Circuit and Separate Heat Recovery Circuit - A cooling circuit and an independent heat recovery circuit are associated with an internal combustion engine. A coolant is circulated a pump in a first and a second cooling sub-circuit. An increase in pressure in a work medium is achieved within the heat recovery circuit by a pump. This work medium is changed from liquid aggregate state to vaporous aggregate state and back to the liquid aggregate state in heat exchangers. This work medium is divided after the pump into two parallel partial flows and is changed into vaporous state in a first parallel branch in an EGR heat exchanger through which recycle exhaust gas flows and in a second parallel branch in an exhaust gas heat exchanger through flow exhaust gas downstream of the low-pressure turbine flows. This vaporous work medium is then fed to an expander and is then conducted through a cooled condenser and, liquefied again. | 06-10-2010 |
| 20120017868 | METHOD AND DEVICE FOR ENGINE BRAKING - A method for engine braking of a multi-cylinder internal combustion engine of a vehicle, which is preferably an engine operating on the diesel principle. The engine has at least one exhaust-gas turbocharger with an exhaust-gas turbine and a charge air compressor, and an exhaust manifold which supplies the exhaust-gas flow from outlet valves of the engine to the exhaust-gas turbocharger. A throttle device is connected between the outlet valves and the turbocharger for throttling the exhaust-gas flow and causing a pressure increase in the exhaust gas for engine braking upstream. An exhaust-gas counter-pressure and a charge air pressure are measured and, based on the measurement, a position of the throttle device can be determined to obtain a predetermined braking action. Then the exhaust-gas counter-pressure and the charge air pressure are closed-loop controlled by adjusting the throttle device corresponding to the previously determined position of the throttle device. A device for engine braking, preferably a diesel engine, has a system for carrying out the novel method. | 01-26-2012 |
| 20120017869 | METHOD AND DEVICE FOR ENGINE BRAKING - A method for engine braking of an engine operating preferably on the diesel principle. Here, the engine has at least one exhaust-gas turbocharger having an exhaust-gas turbine acted on by an exhaust-gas flow and having a charge air compressor, which exhaust-gas turbine and charge air compressor are arranged on a common shaft. The engine also has an exhaust manifold which conducts the exhaust-gas flow from outlet valves of the engine to the exhaust-gas turbocharger, and has a device for throttling the exhaust-gas flow arranged between the outlet valves and the exhaust-gas turbocharger, and also has at least one bypass line for conducting the exhaust-gas flow past the throttling device, the exhaust-gas flow being conducted through the at least one bypass line to a turbine wheel of the exhaust-gas turbine, the exhaust-gas flow being throttled and a pressure increase in the exhaust gas thus being generated upstream of the device for throttling the exhaust-gas flow. According to the method, a measurement of an exhaust-gas counter-pressure and of a charge air pressure preferably take place. On the basis of the measurement of the exhaust-gas counter-pressure and of the charge air pressure, a determination of an optimum position of the device for throttling the exhaust-gas flow to obtain a predetermined braking action can be carried out. The exhaust-gas counter-pressure and of the charge air pressure are subsequently controlled by adjusting the device for throttling the exhaust-gas flow corresponding to the determination of the optimum position of the throttling device. | 01-26-2012 |
