Summary[edit]
| Description |
English: Hino Standardized SCR Unit which combines Diesel Particulate Reduction System (DPR) and Selective Catalytic Reduction (SCR) to reduce pollution from the exhaust. DPR is a diesel particulate filter with additional temperature control to efficiently burn off the soot captured in the filter. The temperature is controlled by triggering small fuel injection bursts to add heat and with the oxygen, the soot in the filter is burned off. The SCR uses the Diesel Exhaust Fluid to react with NOx to convert into nitrogen, water and small amounts of carbon dioxide.
Français : Unité SCR standardisée Hino, combinant un système de réduction des particules diesel (Diesel Particulate Active Reduction ou DPR) et un système catalytique sélective dit SCR (pour Selective Catalytic Reduction) afin de diminuer la pollution induite par les gaz d'échappement de moteurs diesel. Le DPR est un filtre à particules (noir de carbone principalement) couplé à un système de contrôle de température visant à brûler efficacement la suie capturée par le filtre. La température est contrôlée par le déclenchement de petites salves d'injection de carburant en présence d'oxygène. Le SCR utilise l'échappement en y faisant réagir les NOx pour les convertir en azote, en eau et en petites quantités de dioxyde de carbone. |
