Definitions
- the exhaust emission values are dependent on the control speed of the control circuit, in particular in the warm-up phase of the internal combustion engine.
- the stepwise increase or decrease of the lambda value is referred to as the integral component and the sudden return of the lambda value as the jump component.
- This cycle is referred to as a so-called lean / fat amplitude, starting from a lambda setpoint of 1.0, a rich amplitude, for example, at lambda 0.97 and a lean state, for example, at a lambda value of 1.03 Is accepted.
- a disadvantage of this control method is that when unforeseen changes occur, the enrichment or emaciation of the mixture continues after the intended stepwise increase or decrease in the lambda value, until the exhaust gas probe again changes its state from lean to rich or has detected from rich to lean. This causes the control loop to react to changes with a delay.
- the coefficient of the integral component is changed in the case of recognition of a change deviating from the fluctuation of the exhaust gas composition caused by the lean / fat amplitude, in a method according to the preamble of claim 1 / or a jump component is added to or subtracted from the integral component.
- the coefficient or the jump component can be selected individually according to the size of the change so that it is possible to react individually to the respective change.
- the same result can be achieved by increasing the coefficient of the integral component I after the change D has occurred and recognizing it, that is, the curve slopes more steeply, corresponding to I s (see FIG. 2 b).
