Title (EN) DIESEL EXHAUST FLUID INJECTOR
(FR) INJECTEUR DE FLUIDE D'ÉCHAPPEMENT DIESEL
Abstract:
(EN) A diesel exhaust fluid (DEF) injector for an after-treatment apparatus. In use the DEF injector is attached to an outer wall of an after-treatment apparatus for a diesel engine upstream of a selective catalytic reduction device. The DEF injector includes an electrospraying apparatus. The DEF injector is formed from a DEF injection tube that acts as a first electrode and a second electrode spaced from an outlet of the DEF injection tube. The electrospraying apparatus produces an electric field between the first electrode and the second electrode that atomises DEF injected by the DEF injector. The atomised DEF is injected into an exhaust gas stream and the electrospraying apparatus is provided as part of the DEF injector.
(FR) L'invention concerne un injecteur de fluide d'échappement diesel (DEF) pour un appareil de post-traitement. Lors de l'utilisation, l'injecteur de DEF est fixé à une paroi externe d'un appareil de post-traitement d'un moteur diesel en amont d'un dispositif de réduction catalytique sélective. L'injecteur de DEF comprend un appareil d'électropulvérisation. L'injecteur de DEF est formé à partir d'un tube d'injection de DEF qui fait office de première électrode et d'une seconde électrode espacée d'une sortie du tube d'injection de DEF. L'appareil d'électropulvérisation produit un champ électrique entre la première électrode et la seconde électrode qui atomise le DEF injecté par l'injecteur de DEF. Le DEF atomisé est injecté dans un flux de gaz d'échappement et l'appareil d'électropulvérisation est fourni comme partie de l'injecteur DEF.
