Title
(EN) MULTI-FUEL ENGINE CONVERSION SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE DE CONVERSION D'UN MOTEUR POLYCARBURANT
Abstract
(EN)
Systems, methods and apparatus' of converting an engine into a multi-fuel engine are provided. One embodiment reduces particulate emissions and reduces the amount of combusted gasoline or diesel fuel by replacing some of the fuel with a second fuel, such as natural gas, propane, or hydrogen. One feature of the present invention includes a control unit for metering the second fuel. Another feature of the present invention includes an indicator that indicates how much second fuel is being combusted relative to the diesel or gasoline. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

L'invention concerne des systèmes, des procédés et des appareils destinés à convertir un moteur en un moteur polycarburant. Une forme d'exécution réduit les émissions de particules et réduit la quantité de carburant essence ou diesel brûlé en remplaçant certains des carburants par un second carburant, tel que gaz naturel, propane ou hydrogène. Selon une caractéristique de l'invention, il est prévu une unité de réglage pour le dosage du second carburant. Une autre caractéristique de l'invention prévoit un indicateur donnant la quantité de second carburant brûlé par rapport au diesel ou à l'essence.
