Title
(EN) ONBOARD FUEL REFORMING USING SOLAR OR ELECTRICAL ENERGY
(FR) REFORMAGE DE CARBURANT À BORD À L'AIDE D'ÉNERGIE SOLAIRE OU ÉLECTRIQUE
Abstract
(EN)
An operational control system (1) for an internal combustion engine, an internal combustion engine (40), a vehicle (10) and a method of onboard generation of hydrogen in a vehicle (10) being powered by an internal combustion engine (40). The operational control system (1) includes a source of electric current (2), a gas generator (3) with a supply of hydrogen precursor material, an SCR (5) device and a fuel octane boosting device. The gas generator (3) is configured to convert the contained precursor material into an H2 gas by operation of solar energy, electrical energy or both being delivered by the source. The SCR (5) device is fluidly cooperative with the gas generator (3) such that a catalyst-activated fluid-permeable medium disposed in an exhaust gas flowpath defined by the SCR (5) device accepts the passage of the exhaust gas through it and at least intermittently receives the H2 gas from the gas generator (3) to perform catalytic reduction of NOx. Likewise, the fuel octane boosting device defines an H2 gas conduit that is structured to deliver H2 from the gas generator (3) can be at least intermittently introduced to the internal combustion engine as a way to provide an enhanced energy content to diesel, gasoline or related fuel being combusted therein.

La présente invention concerne un système de commande de fonctionnement (1) pour un moteur à combustion interne, un moteur à combustion interne (40), un véhicule (10) et un procédé de génération à bord d'hydrogène dans un véhicule (10) alimenté par un moteur à combustion interne (40). Le système de commande de fonctionnement (1) comprend une source de courant électrique (2), un générateur de gaz (3) avec une alimentation en matériau précurseur d'hydrogène, un dispositif de réduction catalytique sélective (5) et un dispositif d'amplification d'octane de carburant. Le générateur de gaz (3) est conçu pour convertir le matériau précurseur contenu en H2 gazeux par énergie solaire, énergie électrique ou par les deux énergies fournies par la source. Le dispositif de réduction catalytique sélective (5) est en communication fluidique avec le générateur de gaz (3) de telle sorte qu'un milieu perméable au fluide activé par un catalyseur est disposé dans un trajet d'écoulement de gaz d'échappement défini par le dispositif de réduction catalytique sélective (5) accepte le passage des gaz d'échappement à travers celui-ci et reçoit au moins par intermittence le H2 gazeux provenant du générateur de gaz (3) pour effectuer une réduction catalytique de NOx. De même, le dispositif d'amplification d'octane de carburant définit un conduit de H2 gazeux qui est structuré pour délivrer du H2 à partir du générateur de gaz (3) peut être introduit au moins par intermittence dans le moteur à combustion interne de façon à fournir une teneur en énergie améliorée au diesel, à l'essence ou au carburant associé qui est brûlé à l'intérieur de celui-ci.
