Un appareil de production d’un combustible émulsionné comprend une pompe d'alimentation en combustible (24) disposée dans un canal d’alimentation en combustible (20) qui communique avec un moyen de combustion (23), et un moyen de mélange de liquide (10) disposé en amont du canal d'alimentation en combustible (20) et doté d'une chambre de mélange (30) comprenant un côté communiquant avec un réservoir de combustible (12) via une ouverture d’injection (32) et un autre côté communiquant avec un réservoir d’eau (16). La pression négative de la pompe d'alimentation en combustible (24) permettant d’alimenter le moyen de combustion (23) en combustible est en outre appliquée à la chambre de mélange (30), de sorte que le combustible fourni au réservoir de combustible (12) soit injecté dans la chambre de mélange (30) par le biais de l'ouverture d'injection (32) et que l’eau fournie au réservoir d’eau (16) soit introduite dans la chambre de mélange (30), permettant ainsi le mélange du combustible et de l'eau dans la chambre de mélange (30). En mélangeant le combustible et l’eau dans la chambre de mélange (30), un combustible émulsionné est produit, dont une partie est émulsifiée et dont l’autre partie reste sous la forme d’un mélange de combustible et d’eau. En introduisant le combustible émulsionné dans la pompe d'alimentation en combustible (24), l'émulsification du combustible est perfectionnée.
