Abstract

L'invention concerne un système de moteur à émulsion qui simplifie la structure entourant le moteur et dans lequel un combustible à émulsion peut conserver l'état émulsifié d'un carburant et d'un autre fluide sur une longue durée, ce qui permet d'éliminer les troubles provoqués par une séparation du carburant et de l'autre fluide. Le système de moteur à émulsion (100) est équipé d'un moteur (101), d'un dispositif à émulsion (102) qui mélange un carburant avec de l'eau pour produire un combustible à émulsion, d'un réservoir de carburant (104), d'un réservoir d'eau (105) et d'une pompe (106) pour aspirer le combustible à émulsion produit par le dispositif à émulsion (102) et envoyer le combustible à émulsion dans le moteur (101), le dispositif à émulsion (102) ayant été conçu de sorte que l'eau est aspirée à une pression négative depuis l'extérieur du passage du carburant et qu'une force de cisaillement est appliquée sur l'eau aspirée dans le passage du carburant pour cisailler ainsi l'eau en fines gouttelettes afin d'émulsifier l'huile et l'eau.
