Abstract

L'invention concerne une composition d'huile lubrifiante et un procédé de fonctionnement d'un moteur à combustion interne suralimenté. La composition d'huile lubrifiante comprend plus de 50 % en poids d'une huile de base, un détergent surbasique ayant un TBN supérieur à 225 mg KOH/g et un détergent neutre/à faible indice de basicité dont l'indice TBN peut atteindre 175 mg KOH/g. Une quantité totale de calcium présent dans le détergent neutre surbasique et à faible indice de basicité est située dans une plage comprise entre une valeur supérieure à 1100 ppm et inférieure à 2400 ppm en poids sur la base du poids total de la composition d'huile lubrifiante. La composition d'huile lubrifiante et le procédé peuvent être efficaces pour réduire des événements de pré-allumage à basse vitesse dans un moteur à combustion interne suralimenté qui est lubrifié au moyen de la composition d'huile lubrifiante par rapport à des compositions d'huile lubrifiante disponibles dans le commerce.
