Abstract
In a diesel engine equipped with a system for automatic regeneration of a particulate filter, an automatic regeneration mode is inhibited in the case where there is recorded a number higher than a pre-set threshold of unfavorable event. When the automatic regeneration mode is inhibited, an on-demand regeneration mode is simultaneously enabled, which can be activated manually by the driver. If an on-demand regeneration is not performed before the vehicle has covered a certain mileage since the automatic regeneration mode was inhibited, the vehicle is set in a condition of limited performance.
