Auxiliary system for regenerating pollution control means incorporated into the exhaust line of a diesel engine for a motor vehicle

摘要

The invention relates to a system for carrying out a regeneration strategy by means of at least one fuel post-injection into cylinders and is characterised in that the inventive system comprises means (11) for measuring a temperature downstream of catalyst forming means, means (8) for determining a maximum time for applying the post-injections during return to idling phases produced by lifting off and idling according to said temperature and means (7, 8) for immediately stopping the post-injection when the maximum time is attained during the idling phase and/or a progressively reducing the post-injection when the application time attains the maximum value during said idling phase.
