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 calculating an actual fresh-air mass flowing into a cylinder with the aid of an inlet pipe flow model. The description of the flow model is based on a nonlinear differential equation. The chosen model approach contains modeling of an external exhaust-gas recycling system, variable inlet systems and systems with variable control valves. The model-assisted load detection method can be used in engine control systems based on air mass flow and on inlet pipe pressure. A correction algorithm, in the form of a model control loop allows permanent improvement of accuracy when the model parameters are inexact. That is to say model balancing is provided in steady and unsteady operational states.

摘要： In a method for correcting the output signal of a broadband lambda probe of an internal combustion engine, the influence of the air humidity on the lambda value determined by the broadband lambda probe is detected and is deducted by means of a compensation model. For this purpose, a measured air humidity is incorporated in the calibration of the broadband lambda probe during an overrun shut-off phase of the internal combustion engine.

摘要： According to one embodiment of the inventive method, half the cylinders of an in-line cylinder arrangement or the entire internal combustion engine are forcibly excited cylinder-specifically in opposite direction to the other half of the cylinders in order to balance the cylinder-specific total torque. According to another embodiment of the invention, trim regulation which compensates differences between the air quantities and/or fuel quantities introduced into the individual cylinders with the aid of the signal of a joint lambda probe is done cylinder-specifically for the individual catalytic converters. The invention also relates to lambda regulation for the joint main catalytic converter mounted downstream of the cylinder-specific individual catalytic converters.

摘要： In a method and a control apparatus for monitoring an exhaust gas probe, the exhaust gas probe is arranged in an exhaust gas channel. The exhaust gas channel is connected to an internal combustion engine, with the internal combustion engine being supplied with a rich or lean air/fuel ratio in an oscillating fashion.

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： Disclosed is an internal combustion engine comprising at least one cylinder and an exhaust manifold in which a catalytic converter, a first exhaust gas probe, and a second exhaust gas probe are disposed. The first exhaust probe is located upstream from the catalytic converter while the second exhaust gas probe is arranged downstream therefrom. A lambda Controller is provided which is configured so as to determine a lambda correction factor in accordance with a first test signal that is assigned to the first exhaust gas probe. A trim controller is provided to which a setpoint value and an actual value of a second test signal allocated to the second exhaust gas probe are fed as a control difference. The trim controller is configured so as to determine a proportionate corrective factor. A control signal unit is embodied so as to determine a control signal for apportioning fuel into the cylinder in accordance with the lambda correction factor and additionally determine the control signal for apportioning fuel into the cylinder according to the proportionate corrective factor in a diagnostic mode of a component associated with the exhaust manifold.

摘要： In order to control an internal combustion engine, a fuel mass that is to be supplied to the respective cylinder is determined according to a load variable. An additional fuel mass to be measured once is determined, when the measuring signal of an oxygen probe arranged downstream from a three-way catalytic converter is characteristic of at least one pre-determined residual oxygen part, according to the course of the measuring signal. A once reduced fuel mass is determined, when the measuring signal is characteristic of at least one pre-determined residual fuel part, according to the course of the measuring signal. A corrected fuel mass to be measured is determined according to the fuel mass to be supplied and optionally less the once reduced fuel mass or the fuel mass to be measured once. An actuating signal for controlling the injection valve is generated according to the corrected fuel mass to be supplied.
