(EN) CATALYTIC REACTION SYSTEM FOR ENGINE
(FR) SYSTÈME DE RÉACTION CATALYTIQUE POUR MOTEUR
(JA) エンジンの触媒反応システム
Abstract
(EN)
A catalytic reaction system (10) for an engine (90) is equipped with: a catalyst (11) provided in an exhaust passage (91) of the engine (90); a mixer (12) provided upstream from the catalyst (11); a sprayer device (13) for spraying a liquid reduction agent, which is a prescribed liquid, in the form of a spray toward the mixer (12); and a spray control unit (24) for controlling the spray particle size and/or the spray velocity of the sprayer device (13) in accordance with the state of exhaust air in the exhaust passage (91), which is a catalyst installation passage in which the catalyst is provided, such that atomization or gasification of the spray particles proceeds downstream from the mixer (12).
(FR)
Un système de réaction catalytique (10) pour un moteur (90) est équipé : d'un catalyseur (11) disposé dans un passage d'échappement (91) du moteur (90) ; d'un mélangeur (12) disposé en amont du catalyseur (11) ; d'un dispositif de pulvérisation (13) pour pulvériser un agent de réduction liquide, qui est un liquide prescrit, sous la forme d'une pulvérisation vers le mélangeur (12) ; et d'une unité de commande de pulvérisation (24) pour commander la taille des particules de pulvérisation et/ou la vitesse de pulvérisation du dispositif de pulvérisation (13) en fonction de l'état d'air d'échappement dans le passage d'échappement (91), qui est un passage d'installation de catalyseur dans lequel le catalyseur est disposé, de telle sorte que l'atomisation ou la gazéification des particules de pulvérisation se déroule en aval du mélangeur (12).
(JA)
エンジン(90)触媒反応システム(10)は、エンジン(90)の排気通路(91)に設けられる触媒(11)と、触媒(11)の上流側に設けられるミキサ(12)と、所定の液体である還元剤の液体を噴霧としてミキサ(12)に向けて噴射する噴射装置(13)と、ミキサ(12)の下流側における噴霧の微粒化または気化が進むように、触媒が設けられる触媒設置通路部である排気通路(91)の排気の状態に応じて噴射装置(13)の噴射粒径および噴射速度の一方または両方を制御する噴霧制御部(24)とを備える。
