Abstract

Ce procédé se caractérise notamment en ce que l'on émet un faisceau lumineux à travers le mélange alimentant le moteur, on détermine le degré d'absorption de ce faisceau par le mélange dans une bande de longueur d'onde choisie dans l'intervalle de longeur d'onde correspondant au proche infra-rouge et on commande le réglage des paramétres de fonctionnement du moteur en fonction du degré d'absorption ainsi mesuré. Application au réglage automatique des paramètres de fonctionnement d'un moteur à combustion alimenté en mélange alcool-essence.
