Abstract

La présente invention concerne un adaptateur d'injection pour distribuer un additif gazeux SMAE à un moteur à combustion. L'adaptateur d'injecteur comprend un évasement d'adaptateur d'injecteur, un tube d'adaptateur d'injecteur et une barre d'adaptateur d'injecteur. L'évasement d'adaptateur d'injecteur peut être fileté pour permettre sa fixation à un collecteur d'admission d'air et peut être configuré pour distribuer un gaz additif SMAE depuis une ouverture à une de ses extrémités. La fixation de l'adaptateur d'injecteur aussi loin que possible en amont de la ou des chambres du moteur à combustion interne et la distribution de SMAE sensiblement au centre du collecteur d'admission d'air améliorent l'homogénéité du mélange de l'additif gazeux SMAE soit avec l'air aspiré soit avec le mélange de combustion air-combustible dans le collecteur d'admission d'air.
