摘要： The invention relates to a method for operating an internal combustion engine that is equipped with a three-way catalytic converter. According to the inventive method, a lambda value of the air/fuel mixture, with which the internal combustion engine is supplied, is set below and above a set value in a cyclically alternating manner during a forced activation whereby the lambda value in rich phases is less than the set value and in lean phases, is greater than the set value. During the forced activation, the rich phases and the lean phases are matched to one another according to a specified criterion. The invention provides that the amount, by which the lambda value in rich phases is set below the set value, is selected so that it is equal to the amount, by which the lambda value in lean phases is set above the set value. When determining the criterion, an air mass is used that is supplied to the internal combustion engine during the rich and lean phases.

摘要： In order to average the continuously sampled individual values of the measuring signal through totaling over a summation period (TP1, TP2), said period corresponding to the period, dependent on engine speed, of pressure pulsations of the exhaust, while at the same time sparing the memory resources, it is proposed for totaling to be carried out across the N1 individual values block-by-block and already to start before signal updating so that the block values already formed continuously block-by-block up to the update time (tn) and buffered instead of the respective individual values are used for calculating an average.

摘要： A method for determining an opening behavior of a combustion engine fuel injector having a coil drive includes: applying to a coil of the coil drive an electrical test excitation that is weaker than an electrical standard excitation applied to the coil during normal operation of the engine, such that an opening position of the fuel injector is achieved at a point at which the coil drive is not in magnetic saturation; measuring the chronological progression of an electrical variable of the coil; determining a first point in time at which the fuel injector reaches its opening position under the influence of the electrical test excitation, based on the measured chronological progression of the electrical variable, and determining a second point in time at which the fuel injector would reach its opening position under the influence of the electrical standard excitation, based on the determined first point in time.

摘要： During a first driving cycle, a combustion process is controlled in at least one combustion chamber for the purpose of performing a check on an emission reduction system of an internal combustion engine. During a second driving cycle following the first cycle, a check is performed to establish whether an error in the emission reduction system was detected during the first cycle. An idle time between the first and the second cycles is determined, in the event of an error of the emission reduction system detected during the first cycle. During the second cycle, the combustion process in the at least one combustion chamber is only controlled for the purpose of the check on the emission reduction system, in the event of an error detected in the emission reduction system during the first cycle and in the event of the idle time being longer than a pre-determined repair time.

摘要： An internal combustion engine has an exhaust gas catalyst, a first exhaust gas sensor that is arranged for use in lambda control, and a second sensor that is arranged for trim control. The measuring signal of the second sensor is used to determine a NOx quality value depending on the HC quality value and the NOx correction factor. A lambda quality value is determined depending on an actual value and a basic set value of the air/fuel ratio. An error indicator is determined depending on the lambda quality value and the NOx quality value, the error indicator being representative of a mixture component error in a first range and being representative of an exhaust gas catalyst error in a second range. At least one control parameter of a trim control and/or the trim set value of the trim control is adapted depending on the NOx correction factor.

摘要： A method is disclosed for operating an actuator having a coil and a displaceably mounted armature driven by a magnetic field generated by the coil, in a measurement operating mode for ascertaining a time at which the armature reaches its stop position after activation of the actuator. The method includes applying to the coil an actuation voltage signal dimensioned such that the expected armature stop time falls in a time window in which a temporally constant voltage is applied to the coil, detecting an intensity profile of the current flowing through the coil within the time window, and determining the armature stop time, based on an evaluation of the detected current intensity profile. A method for operating such an actuator is also disclosed, wherein information about the stop time is obtained in a measurement operating mode and used in a series operating mode for optimized actuation of the actuator.

摘要： A method for determining a closing time of a valve having a coil drive may include switching off a current flow through a coil of the coil drive so that the coil is depowered, measuring a time curve of a voltage induced in the non-powered coil, wherein the induced voltage is generated at least partially by a motion of the armature relative to the coil, evaluating the measured time curve of the voltage induced in the coil, wherein the evaluation comprises comparing the measured time curve of the voltage induced in the depowered coil to a reference voltage curve stored in an engine controller, and determining the closing time based on the evaluated time curve. The reference voltage curve is thereby adapted to current operating conditions of the valve. A corresponding device and computer program for determining the closing time of a valve comprising a coil drive are also disclosed.
