STRATEGY FOR PRACTICE OF A FAST HEATING PROCESS OF A CATALYST.

摘要

A strategy for implementing a rapid heating process of an oxidation catalyst (8) integrated in the exhaust line of an engine whose operation is commanded by a control calculator (4) that includes a combustion mode manager (19) and a coordinator (23) for managing the passage from one combustion mode to another, the duration of activation of the rapid heating mode being determined based on a deterioration model of the catalyst (8) characterized in that the engine is a diesel engine and why the timing of the implementation of the rapid heating means is a function of the time elapsed since the engine was started and why said determination is made by means of a monitoring and control unit (18 ) of the rapid heating process connected to the combustion modes manager input (19).
