Patent Number Title Of Patent Date Issued
8015805 Method for regenerating an exhaust aftertreatment system September 13, 2011
A method for regenerating an exhaust aftertreatment system, in particular a particulate filter of an internal combustion engine, situated in a vehicle, having regeneration cycles controlled by a control device. An optimized regeneration of the exhaust aftertreatment system is achieved
7937931 Procedure and control unit to operate a diesel engine May 10, 2011
A procedure is introduced to operate a diesel engine, which has a catalytic converter with three-way conversion characteristics. The procedure is characterized thereby, in that if the engine rotational speed increases without in the process exceeding an engine rotational speed thresh
7665295 Method for operating an internal combustion engine and device for implementing the method February 23, 2010
A method is provided for operating an internal combustion engine in whose exhaust-gas region an exhaust-gas treatment device is situated, and in which a reagent is introduced into the exhaust-gas region of the internal combustion engine. in addition, a device is provided for implementing
7500465 Method for operating an internal combustion engine March 10, 2009
A method for operating an internal combustion engine, in which fuel is injected into a combustion chamber of a cylinder of the internal combustion engine in at least two partial injections, and in which an actual torque supplied by the internal combustion engine is ascertained from o
7337658 Method for operating an internal combustion engine March 4, 2008
A method is described for operating an internal combustion engine, in particular of a motor vehicle. In the method, a lean air/fuel mixture is burned in a combustion chamber; nitrogen oxides contained in the exhaust gas are stored in an accumulator-type catalytic converter; a storage
7337059 Method and device for operating an internal combustion engine February 26, 2008
A method and a device for controlling an internal combustion engine. In a first operating mode, a fuel quantity is predefined according to a first rule for calculating the quantity based on at least the torque variable. In a second operating mode, the fuel quantity is predefined accordin
7150261 Method and device for controlling an internal combustion engine December 19, 2006
A device and a method for controlling an internal combustion engine in which a fuel-quantity variable is ascertained on the basis of at least one torque variable. For at least two operating modes the fuel-quantity variable is ascertained according to two different procedures.
7127882 Method and controller for exhaust gas temperature control October 31, 2006
Described is a method for controlling a temperature downstream of a catalyst in the exhaust tract of an internal combustion engine including a first control loop in which a first control variable is calculated from a first deviation that is calculated from a first actual value and a
6968682 Method and device for controlling an internal combustion engine with an exhaust treatment system November 29, 2005
In a method and device for controlling an internal combustion engine having an exhaust treatment system, a quantity characterizing the status of the exhaust treatment system is determined on the basis of at least one operating parameter of the internal combustion engine.
6752126 Method and device for controlling an internal combustion engine June 22, 2004
A method and a device is described for controlling an internal combustion engine using fuel metering. The fuel metering is divisible into at least a first partial injection and a second partial injection. In the second partial injection, a fuel quantity variable, characterizing the fuel
6698396 Method and device for injecting fuel in an internal combustion engine March 2, 2004
The present invention relates to a device and a method for dividing up a total fuel amount, which is to be injected into the combustion chamber of a cylinder during a combustion cycle, into a plurality of injections. To this end, a first fuel amount, which is to be injected during a firs
6519516 Method and device for safeguarding against manipulation of an odometer or a trip recorder February 11, 2003
A method of safeguarding against manipulation of an odometer or trip recorder in a motor vehicle, in which the instantaneous odometer reading is determined when the engine of the motor vehicle is stopped and that odometer reading is stored in an on-board control unit, in particular an
