Abstract: front page image
(EN)The present invention relates to a method for controlling a combustion engine provided with an exhaust gas temperature sensor (20) and using at least compressed natural gas contained in a tank (12) equipped with a pressure sensor (21) as one of its fuels. As soon as a filling of the tank (12) is detected, the method includes the following steps: - comparing the temperature sensed by the exhaust gas temperature sensor (20) with the theoretical temperature expected for this sensor; determining a natural gas quality class according to the result of the comparison; - revising the engine control according to the determined natural gas quality class. The invention also relates to an engine control unit.
(FR)La présente invention concerne un procédé de commande d'un moteur à combustion doté d'un capteur de température de gaz d'échappement (20), et dont au moins un carburant est le gaz naturel comprimé contenu dans un réservoir (12) pourvu d'un capteur de pression (21). Lors de la détection d'un événement de remplissage dudit réservoir (12), le procédé comprend les étapes suivantes : - comparaison de la température captée par le capteur de température de gaz d'échappement (20) avec une température théorique prévue pour ce capteur ; - détermination d'une classe de qualité pour le gaz naturel en fonction du résultat de la comparaison ; - application d'une révision à la commande du moteur en fonction de ladite classe de qualité déterminée pour le gaz naturel. La présente invention concerne également une unité de commande de moteur.
(PT)A presente invenção refere-se a um processo de controle de um motor de combustão munido de um sensor de temperatura de gases de escape (20) e cujo ao menos um combustível é gás natural comprimido contido em um tanque (12) munido de um sensor de pressão (21). Logo depois de detectar um evento de abastecimento do dito tanque (12), o processo inclui as seguintes etapas: - comparar a temperatura captada pelo sensor de temperatura de gases de escape (20) com a temperatura teórica esperada para esse sensor; - determinar uma classe de qualidade para o gás natural em função do resultado da comparação; - aplicar uma revisão ao controle do motor em função da dita classe de qualidade determinada para o gás natural. A presente invenção também se refere a uma unidade de controle de motor.
