METHOD FOR THE CONTINUOUS LAMBDA CONTROL OF AN INTERNAL COMBUSTION ENGINE HAVING A CATALYZER |
摘要 |
The invention relates to a method for the continuous lambda control of an internal combustion engine 13 having a catalyzer. The method is carried out by generating a control oscillation FS of pregiven amplitude at least in pregiven operating conditions. This method is based on the recognition that with an increase in amplitude of the control oscillation, the conversion window becomes wider insofar as a maximum amplitude is not exceeded. The conversion window is that range of lambda values wherein the conversion exhibits at least a pregiven quality.
