Method and system for purge cycle management of a lean NOx trap |
摘要 |
Purging of a NOX trap is initiated if the estimated mass of NOX in the trap exceeds a NOX mass threshold value unless the estimated probability that the engine will be subjected to high load and high speed conditions exceed a probability threshold value, in which event the decision whether to initiate the purging of said trap is delayed for a predetermined time interval.
