Abstract:
(EN) The present invention relates to a harmful emissions reduction apparatus for an engine using a reformer, a reformer for the same, and a harmful emissions reduction method for an engine using the same. The harmful emissions reduction apparatus for an engine comprises: a reformer (20) which reforms oxygen (O) and hydrocarbons (HC) included in the exhaust gas from an engine into hydrogen (H2) and carbon monoxide (CO), and increases the temperature of the exhaust gas by exothermic reaction; an exhaust gas recirculation unit (EGR) (30) which supplies the engine (10) with the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and stabilizes the homogeneous charge compression ignition (HCCI) combustion of the engine (10); a hydrocarbon-added selective catalytic reduction unit (HC-SCR) (40) which receives the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and transforms the nitrogen oxide (NOx) into nitrogen (N2) and water vapor (H2O) using hydrocarbons as a reducing agent in a state that enhances the reduction reaction of the nitrogen oxide (NOx); and a diesel particulate filter (DPF) (50) which receives the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and removes particulate matter (PM) deposited thereinside through oxidation. The harmful emissions reduction apparatus for an engine of the present invention treats the exhaust gas more efficiently as post-processing apparatuses such as the selective catalytic reduction (HC-SCR) and the diesel particulate filter (DPF) are interacting in addition to the application of the HCCI combustion and the reformer.
(FR) La présente invention concerne, d'une part un appareil qui sert à réduire les émissions nocives d'un moteur au moyen d'un reformeur, d'autre part un tel reformeur, et enfin un procédé de réduction des émissions nocives d'un moteur au moyen d'un tel appareil. L'appareil utilisé pour réduire les émissions nocives d'un moteur comprend un reformeur (20), un recycleur de gaz d'échappement (30), un réducteur catalytique sélectif à injection d'hydrocarbures (40), et un filtre à particules (50). Le reformeur (20) reforme en hydrogène (H2) et en monoxyde de carbone (CO) l'oxygène (O) et les hydrocarbures (HC) présents dans les gaz d'échappement provenant du moteur, et augmente par réaction exothermique la température des gaz d'échappement. Le recycleur de gaz d'échappements (30) ou "EGR" (Exhaust Gas Recirculation unit) fournit au moteur le gaz d'échappement reformé par le reformeur (20) de façon à augmenter la teneur en hydrogène, et stabilise la combustion par allumage par compression de charge homogène ou "HCCI" (Homogeneous Charge Compression Ignition) du moteur (10). Le réducteur catalytique sélectif à injection d'hydrocarbures (40) ou "HC-SCR" (Hydrocarbon-Added Selective Catalytic Reduction unit) reçoit les gaz d'échappement qui ont été reformés par le reformeur (20) de façon à augmenter le teneur en hydrogène (H2), et transforme l'oxyde d'azote (NOx) en azote (N2) et en vapeur d'eau (H2O) en utilisant comme réducteurs les hydrocarbures dans un état qui renforce la réaction de réduction de l'oxyde d'azote (NOx). Le filtre à particules diesel (50), généralement appelé "FAP", reçoit les gaz d'échappement qui ont été reformés par le reformeur (20) de façon à augmenter la teneur en hydrogène (H2), et élimine la matière particulaire déposée à l'intérieur par l'oxydation. L'appareil à réduire les émissions nocives d'un moteur selon la présente invention traite les gaz d'échappement plus efficacement car les appareils de traitement postérieur tels que le réducteur catalytique sélectif (HC-SCR) et le filtre à particules diesel (FAP) opèrent une interaction qui vient compléter la combustion HCCI et le reformage par le reformeur.
