Strategy for implementing a quick-heating process of a catalyst

摘要

The method involves determining an activation period of a rapid heating mode based on a damage model of an oxidation catalyst integrated to an exhaust line of a four cylinder oil engine of a vehicle, and a heating time of the catalyst based on operating conditions such as time elapsed from the starting of the engine. The determination of the period and the time is carried by a controlling and monitoring device (18) i.e. supervisor, that is connected to an input of a combustion mode manager (19) for controlling and monitoring a rapid heating process of the catalyst.
