Abstract

L'invention concerne un dispositif d'injection d'additif destiné à des moteurs à combustion interne comportant un réservoir d'additif et capable d'injecter ledit additif dans une phase gazeuse, ledit additif permettant de modifier les propriétés chimicophysiques de la combustion et de ses produits dérivés. Selon l'invention, ledit dispositif d'injection comporte des éléments de pulvérisation de microjets liquides (14, 45) contenant au moins une microchambre de pression (21) destinée à recevoir l'additif, une microbuse (23) et des éléments destinés à appliquer une pression (24) à l'additif contenu dans la microchambre de pression.
