Abstract
Lors de l'adaptation d'un moteur à combustion interne pour qu'il soit rempli avec du combustible gazeux, il est préférable que le changement au moteur et l'interférence du combustible gazeux entre les ports d'entrée respectifs soient réduits lors de l'ajout d'un système d'injection à port. Un appareil à port d'injection est fourni pour introduire un combustible gazeux dans un port d'entrée d'un moteur à combustion interne qui comprend un collecteur d'entrée ayant une chambre de distribution qui connecte l'entrée d'air au port d'entrée de manière fluide. L'appareil d'injection à port comprend un trou dans le collecteur d'entrée. Un tube d'injection monté au trou s'étend de la chambre de distribution jusqu'au port d'entrée. Le tube d'injection comprend une entrée placée près du trou et une sortie connexe au port d'entrée. Une valve est connectée de manière fluide pour recevoir une alimentation en combustible gazeux et pour introduire le combustible gazeux dans l'entrée du tube d'injection.
