Abstract

Une composition de lubrification pour réduire le préallumage basse vitesse (LSPI) dans les moteurs à combustion interne allumés par étincelle et lutilisation dune composition lubrifiante pour réduire les LSPI dans de tels moteurs. Idéalement, la composition comprend un groupe détergent à calcium boré qui fournit le calcium de la composition à raison de 0,12 % en poids en fonction du poids de la composition, où le détergent à calcium boré de la composition représente au moins 100 ppmw, en fonction du poids de la composition. La composition peut également comprendre un premier détergent comprend un détergent à calcium et un deuxième détergent comprenant un détergent à calcium boré.
