A regeneration device of an exhaust gas purification filter that reduces the regeneration time of the filter. The regeneration device includes a plurality of first temperature detectors (26a, 26b) arranged in casings to detect the temperature in each casing and a second temperature detector (26a, 26b) for detecting the temperature of the exhaust gas. A processor (30) is connected to the first temperature detectors and the second temperature detector. The processor compares the temperature of the exhaust gas and the temperature of at least one of the casings, opens the associated switch valve based on the comparison result, and preheats at least one of the filters with the exhaust gas. The heat of the exhaust gas suddenly increases the temperature of the filter from the initial temperature and reduces the filter regeneration time.

Cette invention concerne un dispositif permettant de reformer plus rapidement un filtre à gaz d'échappement, qui comprend des logements abritant chacun une pluralité de premiers détecteurs de température (26a, 26b) faits pour détecter la température dans lesdits logements, et une pluralité de seconds détecteurs de température (26a, 26b) conçus pour détecter la température des gaz d'échappement. Un processeur (30), qui est relié aux premiers et aux seconds détecteurs de température, compare la température dans les logements à celle des gaz d'échappement. Selon les résultats de la comparaison, des soupapes de commutation particulières s'ouvrent et l'un au moins des filtres est préchauffé par les gaz d'échappement. La température initiale du filtre augmente brusquement, ce qui a pour effet de réduire le temps requis pour réformer le filtre.
