The invention concerns a method for correcting ignition advance of an internal combustion engine based on the variation of the natural gas composition contained in a tank and feeding said engine. It consists in determining a methane index with respect to the natural gas filling said tank and deducting therefrom a value for correcting ignition advance. The invention is characterised in that a correlation has been established between said methane index, a ratio air flow/fuel flow rate R for a stoichiometric combustion and the variation in the gas flow rate required to obtain a reference operational point of the engine following the variation in the composition of said gas.

La présente invention a pour objet une méthode de correction de l'avance à l'allumage d'un moteur à combustion interne en fonction de la variation de la composition du gaz naturel contenu dans un réservoir et alimentant ledit moteur. On détermine un indice de méthane relatif au gaz naturel remplissant ledit réservoir et on déduit dudit indice une valeur de correction de l'avance à l'allumage. Il a été établi selon l'invention, une corrélation entre l'indice de méthane précédemment décrit, un rapport R débit air/débit carburant pour une combustion stoechiométrique et la variation de débit du gaz nécessaire pour atteindre un point de fonctionnement de référence du moteur à la suite de la variation de composition de ce même gaz.
