摘要： Method for lambda control in an internal combustion engine with a catalytic converter in an exhaust tract and at least one lambda probe mounted inside the catalytic converter. With this arrangement of the upstream probe there are signal delays which slow down the lambda control. To compensate, the measurement signals from the first lambda probe are applied to a lambda analysis unit which corrects measurement signal delays, and the corrected lambda probe signal is applied to a unit for lambda control. Both lambda probes are connected to a unit for lambda control.

摘要： A device is designed for determining a pre-set air/fuel ratio in the combustion chamber of a cylinder of an internal combustion engine. The device is further designed for determining a filtered, pre-set air/fuel ratio in the combustion chamber of the cylinder by filtering the pre-set air/fuel ratio in the combustion chamber of the cylinder by means of a filter which models the dynamic behavior of the upstream region of the exhaust gas catalyst relative to the arrangement of the exhaust gas probe in the exhaust gas catalyst, in particular its storage, reduction and/or oxidation properties. The device is further designed for determining an adjustable variable by means of a regulator as a function of the filtered and pre-set air/fuel ratio, and of a sensed air/fuel ratio in the combustion chamber of the cylinder.

摘要： The invention relates to a device for controlling an internal combustion engine, comprising a first regulator, whose regulating difference is the difference of an actual value and an estimated value of individual cylinder deviation of the air/fuel ratio from a preset air/fuel ratio. The first regulator also has an integral regulating parameter, its manipulated variable being a first estimated value. A second regulator is also provided, the regulating difference of which is the first estimated value. Said regulator has a proportional regulating parameter whose manipulated variable is an individual cylinder lambda regulating factor. A PT1 filter is additionally provided, by means of which a second estimated value is determined through PT1 filtering of the individual cylinder lambda regulating factor. A unit is also provided, said unit determining the estimated value of the individual cylinder deviation of the air/fuel ratio from the preset air/fuel ratio based on the difference between the first and the second estimated values. Depending on the individual cylinder lambda regulating factor, a fuel mass that is to be proportioned is corrected and the thus corrected fuel mass to be proportioned is considered in order to determine a regulating signal for the corresponding injection valve.

摘要： The invention relates to a method for regulating the lambda value of an internal combustion engine with a catalytic converter for subsequently treating the exhaust gases of the internal combustion engine, with a binary lambda probe, which is mounted upstream from the catalytic converter and which senses the composition of the exhaust gases. According to the invention, the lambda set value is superimposed with a lean/rich amplitude. This lean/rich amplitude has an integral component and a discontinuous component leading back to the lambda set value. When a change that differs from the change in the exhaust gas composition caused by the lean/rich amplitude is detected, the coefficient of the integral component is modified and/or a discontinuous component is added to the integral component or subtracted therefrom.

摘要： A method for purifying the exhaust gas from an internal combustion engine, which is operated under lambda-based closed loop control and which has an exhaust gas tract in which is located a catalytic converter, is provided. According to this method, a pre-converter lambda value for the exhaust gas is continuously sensed upstream of the catalytic converter, from which a pre-converter lambda signal is generated, and this pre-converter lambda signal is used as the reference variable for the lambda control loop. A post-converter lambda value for the exhaust gas is continuously sensed downstream from the converter, from which a post-converter lambda signal is generated, this being a monotonically decreasing function of the lambda value for the exhaust gas downstream from the catalytic converter. The post-converter lambda signal is used in a trimming control loop to apply a correction to the lambda control loop, whereby a measurement signal is generated which, at least below a certain value of lambda close to lambda=1, is a strictly monotonically increasing or monotonically decreasing function of the lambda value for the exhaust gas downstream from the catalytic converter. For levels of the post-converter lambda signal which are above a threshold value, this supplementary measurement signal is used for trimming control. For levels of the post-converter lambda signal which are below the threshold value, the post-converter lambda signal itself is used for trimming control.

摘要： A method of monitoring the dynamic operability of a lambda sensor (monitor sensor), disposed in the exhaust gas stream of an internal combustion engine downstream of a catalytic converter. Once the engine operating state of overrun fuel cutoff is detected, the rich/lean switching time of the monitor sensor disposed downstream of the catalytic converter is ascertained and weighted as a function of the air flow rate (LMM) in the intake conduit. By comparing the mean value of the thus-obtained switching time with a limit value and ensuing evaluation, the operability of the monitor sensor is diagnosed. Operability is assured if the switching time is below the limit value. Other diagnostic criteria are formed by evaluating the signal level of the monitor sensor.

摘要： Periodic forced stimulations are asserted on setpoint values for a lambda control and a system response of a lambda control loop is simulated by a model that includes a sensor delay time as the model parameter. Amplitude gains of the model and the system are compared with each other and adapted according to the result of the comparison of the model parameters. If the adaptation value lies above a threshold, a lambda probe is classified as defective.

摘要： Each cylinder bank of the internal combustion engine is assigned in each case one injection event memory (EES), an injection determining process (EEP) and an injection execution process (EAP). In the respective injection determining process (EEP), desired injection events (EE) are determined for the associated cylinder bank. These injection events are stored in succession in the respectively associated injection event memory (EES). In the respective injection execution process (EAP), injection events (EE) are retrieved in succession from the associated injection event memory (EES) and executed in a sequence in which they were stored in the associated injection event memory (EES) by the associated injection determining process (EEP) (FIFO: first in first out). The in each case next injection event (EE) is executed only after the end of an execution of the in each case previously executed injection event (EE).
