20100037873 | INTERNAL COMBUSTION ENGINE AND ASSOCIATED OPERATING METHOD - In a method of operating an internal combustion engine having at least two combustion chambers, each combustion chamber contributes torque to the total torque of the internal combustion engine, and the internal combustion engine is designed in such a way that a quantity of exhaust gas can be recycled into combustion chambers. The method has the steps: (a) detecting the torque contributions of at least two combustion chambers, then (b) changing the quantity of exhaust gas recycled into the combustion chambers, the torque contribution of which has been detected in step (a), then (c) detecting the torque contributions of at least two combustion chambers, the torque contribution of which has been detected in step (a), then (d) determining the change in the torque contributions as a result of the change in the quantity of recycled exhaust gas, and then (e) outputting a signal as a function of the change in the torque contributions. | 02-18-2010 |
20100049426 | METHOD FOR DETERMINING AN UNCONTROLLED ACCELERATION OF AN INTERNAL COMBUSTION ENGINE - In a method for determining an uncontrolled acceleration of an internal combustion engine, a valve opening cross section is allocated to each load state of the internal combustion engine. In the event that a controller value is outside a limit range, an uncontrolled acceleration of the internal combustion engine is thereby detected. | 02-25-2010 |
20100192911 | Injection System, and Method for the Production of an Injection System - An injection system for injecting fuel has an actuator, a pilot valve with a valve mushroom, and a supply throttle. The control chamber encompasses a control piston, a first discharge throttle, a first sealing edge for forming a first sealing seat along with the valve mushroom, a second sealing edge of a piston chamber with a valve piston, the second sealing edge forming a second sealing seat along with the valve piston during a maximum actuator working lift for sealing the piston chamber and the valve chamber from each other; and a second discharge throttle connecting the piston chamber to the low-pressure zone between the first and the second sealing edge, wherein d | 08-05-2010 |
20110116938 | METHOD FOR CONTROLLING A HIGH-PRESSURE FUEL PUMP - In a method for controlling a high-pressure fuel pump, which comprises an electrically controllable electromechanical inlet valve ( | 05-19-2011 |
20110118958 | METHOD FOR ADAPTING THE PERFORMANCE OF A FUEL PREFEED PUMP OF A MOTOR VEHICLE - In a method for adapting the performance of a fuel prefeed pump of a motor vehicle which has a common rail injection system and an internal combustion engine, after the ignition is switched on and before the internal combustion engine is started, adaptation values are determined and stored which are assigned to the fuel prefeed pump and describe its individual performance. After the internal combustion engine is started, the stored adaptation values are taken into consideration during the determining of an actuating signal for the prefeed pump. | 05-19-2011 |
20110120417 | METHOD AND DEVICE FOR CONTROLLING THE FUEL PRESSURE IN THE PRESSURE ACCUMULATOR OF A COMMON-RAIL INJECTION - In a method and a device for controlling the fuel pressure in the pressure accumulator of a common-rail injection system, the difference between the actual engine speed and a target engine speed is established, and an injection time is determined based on the determined difference. The fuel pressure is controlled according to the determined injection time. | 05-26-2011 |
20130019670 | METHOD FOR DETECTING A MALFUNCTION IN AN ELECTRONICALLY REGULATED FUEL INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE - A method is provided for detecting a malfunction in an electronically regulated fuel injection system of an internal combustion engine, by which effective limitation of the cause of the fault in a fuel injection system can take place. For example, it can be determined whether the cause of the fault lies in the low pressure system or in the high pressure system of the fuel injection system. | 01-24-2013 |
