Abstract

Il existe de nombreuses propositions pour économiser de l'essence, par une façon appropriée de conduire le véhicule. Selon l'invention, on coupe l'arrivée de carburant dans l'alimentation du ralenti quand la voiture fonctionne en frein moteur, ou quand la consommation principale est décroissante. L'invention prévoit aussi un dispositif pour la mise en oeuvre de ce procédé. On réalise une économie de carburant, tout en améliorant le freinage (ralentisseur) et on diminue la pollution.
