Process for checking a burner system for heating a catalytic converter |
摘要 |
In order to diagnose a burner air ratio, a fuel/air mixture of an internal combustion engine is either enriched or diluted during operation of the burner as a function of an instantaneous state of the mixture. Resulting signal levels of lambda probes disposed upstream and downstream of the catalytic converter are evaluated.
