| Number | Title | Issue Date |
| 6477940 | High-pressure piston cylinder unit The invention relates to a high-pressure piston cylinder unit, especially an injection pump or an injection valve for an internal combustion engine, and to a method for producing one such high-pressure piston cylinder unit. The high-pressure piston cylind... | 11/12/2002 |
| 5758718 | Plate heat exchanger A heat exchanger of a plate construction, as used, for example, in a water-cooled charge air cooler with air-side lamella plates avoids undesirable thermal expansion effects which occur in the transient operation of a charge air cooler and result in damag... | 06/02/1998 |
| 5651346 | Accumulator-type injection system An accumulator-type injection system having an injector and a control valve connected with the injector for controlling injection. In a first switching position of the control valve, an injector body fuel duct, which leads in front of the orifices, is con... | 07/29/1997 |
| 5551403 | Fuel supply quantity limiting arrangement An arrangement limits a fuel supply from a fuel pressure reservoir by way of a controllable injection valve into the combustion space of an internal-combustion engine. The fuel flow is interrupted as a function of the forces applied to a spring-prestresse... | 09/03/1996 |
| 5526792 | Intermittent fuel supply injection system and method An injection system provides an intermittent supply of fuel mixture into combustion spaces of an internal-combustion engine. The system includes a valve and a pipe by way of which a control space in the injection valves may alternatively be acted upon by ... | 06/18/1996 |
| 5463867 | Supercharged internal combustion engine exhaust system An exhaust system for a supercharged internal-combustion engine in which of the exhaust-gas-carrying components, the exhaust gas pipes leading from the cylinder outlets to the turbines, or the turbines, or the turbines and the exhaust gas pipes are arrang... | 11/07/1995 |
| 5253985 | Exhaust gas turbocharger having rotor runners disposed in roller bearings An exhaust gas turbocharger having rotor runners disposed in roller bearings protects the roller bearings from shocks and vibrations by a pressure-oil-filled oil film damper. By a shut-off device arranged in the main lubricating oil duct, the lubricating ... | 10/19/1993 |
| 5179916 | Piston with a rotatable piston top This invention relates to a two piece piston with a variable compression height, wherein a piston top part can be adjusted with respect to a piston bottom part along the longitudinal axis of the piston preferably by hydraulic devices and can be caused to ... | 01/19/1993 |
| 5056310 | Exhaust pipe for a multi-cylinder piston internal-combustion engine An interior pipe carrying exhaust gases is arranged in a cooled housing 13. The interior pipe fastened to the housing 13 comprises individual sections 18 arranged in series while leaving expansion joints. The length of one section 18 corresponds approxima... | 10/15/1991 |
| 5053120 | Arrangement for draining water collecting in the container of a water separator of an internal-combustion engine The invention relates to an arrangement for the automatic removal of water collecting in a fuel filter having a water separator. The evacuation takes place by means of a piston acted upon by a pressure medium, preferably a fuel pressurized by the pressure... | 10/01/1991 |
| 4903489 | Supercharged multi-cylinder reciprocating piston-internal combustion engine with several exhaust gas turbochargers operating in parallel During idling or partial load of the reciprocating piston-internal combustion engine, the exhaust gas turbocharger (18) is shut-down and the fuel supply is interrupted with some cylinders (12). An optimum charging air supply matched to the operating condi... | 02/27/1990 |
