Abstract
L'invenzione concerne un dispositivo presentante un servomotore per la rigenerazione di un filtro per la combustione di fuliggine nel canale di scarico di un motore a combustione interna a iniezione a compressione d'aria con un regolatore meccanico di numero di giri e con un dispositivo di compensazione di altezza dipendente dalla pressione atmosferica in cui il dispositivo di rigenerazione è incorporato in modo tale che, in presenza di contropressione di scarico crescente, attraverso il dispositivo di compensazione di altezza si agisce sul regolatore del numero di giri nel senso di una riduzione della portata di iniezione da dosare per il motore a combustione interna.
