Patent number: 4522358Abstract: A system for the displacement of two thrust reversers for two jet engines of an airplane. Each thrust reverser has a drive motor operated by compressed air, a valve controlling the flow of compressed air to the motor, a set-point indicator including an input piston controllable by the action of compressed air, a differential transmission, and a feedback system from the motor to the differential transmission. The valve is actuated by the input piston and the motor via the differential transmission. The displacement of the two thrust reversers is halted by a system of stops acting on the input pistons at identical intermediate points in the paths of travel thereof and the displacement is thereafter continued after the thrust reversers have both reached their intermediate points in their paths of travel by deactivation of the stops.Type: GrantFiled: June 13, 1983Date of Patent: June 11, 1985Assignee: MTUInventors: Hans Dinger, Hilbert Holzhauer, Erberhard Lang

Patent number: 4453381Abstract: In the operation of supercharged internal combustion engines, certain operating conditions exist during which the exhaust gas turbochargers cannot supply adequate supercharging air for the internal combustion engine due to a low production of exhaust gas by the engine. To eliminate this problem, an auxiliary compressor with a flywheel is proposed, which is constantly driven by an auxiliary drive mechanism and whose power input can be considerably reduced by closing its air conduit. In case of lacking charging air, the auxiliary compressor is used in a simple way, by opening the closure devices on its air side, in order to enable a supply of supercharging air to the internal combustion engine. The power required for driving the auxiliary compressor is derived primarily from energy stored in the revolving flywheel mass as well as from the power of the auxiliary drive mechanism.Type: GrantFiled: January 6, 1982Date of Patent: June 12, 1984Assignee: MTU Motoren- und Turbinen-Union Friedrichshafen GmbHInventor: Hans Dinger

Patent number: 4429533Abstract: An internal combustion engine supercharged by exhaust turbochargers, with the engine being provided with an auxiliary combustion chamber, the exhaust gas of which is temporarily fed to a turbine of an exhaust gas turbocharger for improving acceleration characteristics of the internal combustion engine. The combustion air for the auxiliary combustion chamber is derived from a stream of supercharging air produced by the exhaust turbocharger. At least two exhaust turbochargers are provided with compressors thereof both conveying or feeding into a supercharging air conduit, to all cylnders of the internal combustion engine. Each of the compressors are equipped on an intake side with one check valve. During an idling or partial load, the exhaust gas of the internal combustion engine is fed to only one of the two exhaust turbochargers, wherein a conveying air stream produced by this exhaust turbocharger effects an automatic closing of the check valve of the other exhaust turbocharger.Type: GrantFiled: July 6, 1981Date of Patent: February 7, 1984Assignee: MTU-Motoren- und Turbinen-Union Friedrichshafen GmbHInventor: Hans Dinger

Patent number: 4422296Abstract: An internal combustion engine which is supercharged by exhaust gas turbochargers and which includes an auxiliary combustion chamber. Exhaust gases from the auxiliary combustion chamber are temporarily fed to turbines of the exhaust gas turbocharger for improving acceleration characteristics of the internal combustion engine. The combustion air for the auxiliary combustion chamber is derived from the stream of supercharging air produced by the turbochargers. At least two exhaust turbochargers are provided which operate in parallel. In case of acceleration of the engine, the exhaust gases from the internal combustion engine circumvent the turbines of the exhaust gas turbochargers, and then the exhaust gases of the auxiliary combustion chamber alone effect the drive for all exhaust gas turbochargers.Type: GrantFiled: August 4, 1981Date of Patent: December 27, 1983Assignee: MTU-Motoren-und Turbinen-Union Friedrichshafen GmbHInventors: Hans Dinger, Helmut Klotz

Patent number: 4388802Abstract: An internal combustion engine which is adapted to be supercharged by at least two exhaust gas turbochargers operating in parallel. The engine includes an auxiliary combustion chamber, the exhaust gas of which is temporarily fed to a turbine of an exhaust gas turbocharger for improving an acceleration characteristic of the internal combustion engine. Combustion air for an idling operation of the auxiliary combustion chamber is derived from a stream of supercharging air produced by the exhaust gas turbocharger. During a partial load operation of the engine, only one of the exhaust gas turbochargers is supplied with an entire volume of the exhaust gas of the internal combustion engine to provide the supply of supercharging air. The exhaust gas from the auxiliary combustion chamber, operated with a full load for the case of accelerating in a lower load range of operation of the internal combustion engine, is fed to the turbine of the other exhaust gas turbocharger.Type: GrantFiled: August 4, 1981Date of Patent: June 21, 1983Assignee: MTU Motoren-und Turbinen-Union Friedrichshafen GmbHInventors: Hans Dinger, Helmut Klotz
