Title
(EN) REGENERATION SYSTEM AND REGENERATION METHOD FOR DIESEL PARTICULATE COLLECTING FILTER
(FR) SYSTÈME DE RÉGÉNÉRATION ET PROCÉDÉ DE RÉGÉNÉRATION POUR FILTRE DE COLLECTE DE MATIÈRE PARTICULAIRE DIESEL
(JA) ディーゼル微粒子捕集フィルターの再生システムと再生方法
Abstract
(EN) In this regeneration system for a diesel particulate collecting filter, in order to prevent a decrease in the temperature of exhaust gas flowing through a PM reduction device (1) and a pipe (3) linking the PM reduction device (1) with an engine (2): a substance which has a tubular cross-sectional shape and the inside of which is filled with air is wrapped in a helical shape around the periphery of the pipe (3) and/or the PM reduction device (1); the outer periphery thereof is covered by a flat plate and both ends of the flat plate are closed; and a hermetically sealed space formed between the pipe (3) and/or the PM reduction device (1) and the flat plate of which both ends are closed is evacuated.
(FR) Dans ce système de régénération pour un filtre de collecte de matière particulaire diesel, afin d'empêcher une diminution de la température des gaz d'échappement s'écoulant à travers un dispositif de réduction PM (1) et un tuyau (3) raccordant le dispositif de réduction PM (1) à un moteur (2) : une substance qui a une forme de section transversale tubulaire et dont l'intérieur est rempli d'air est enveloppée sous une forme hélicoïdale autour de la périphérie du tuyau (3) et/ou du dispositif de réduction PM (1) ; sa périphérie externe est recouverte par une plaque plate et les deux extrémités de la plaque plate sont fermées ; et un espace hermétiquement scellé formé entre le tuyau (3) et/ou le dispositif de réduction PM (1) et la plaque plate dont les deux extrémités sont fermées est évacué.
(JA) ディーゼル微粒子捕集フィルターの再生システムにおいて、PM低減装置(1)及びPM低減装置(1)とエンジン(2)を連結する配管(3)を流動する排ガスの温度低下を防止するため、配管(3)及び/又はPM低減装置(1)の周囲に、筒状の断面形状を有し、内部が空気で満たされた物質をらせん状に巻き付け、その外周を平板で覆って平板の両端を閉じ、配管(3)及び/又はPM低減装置(1)と、両端が閉じられた平板との間に形成された密閉空間を真空にする。
