Abstract[English]
conjugated dienes, and combinations thereof; iii) at least one overbased metal containing detergent with a Total Base Number (KOH/g) greater than or equal to 9 and less than or equal to 500 and included at a treat level to deliver between 100 to 5000 ppm by weight of total metal and between 0.15 wt. % to 8.0 wt. % of total soap to the composition; and iv) the lubricating oil composition having a total sulfated ash of less than or equal to 2.5 wt.%, a total phosphorous level of less than or equal to 0.120 wt.%, and a SAE viscosity grade of 25W-X, 20W-X, 15W-X, 10W-X, 5W-X or 0W-X, where X represents any one of 8, 12, 16, 20, 30, 40, 50 or 60; b) providing a fuel comprising hydrogen to the HICE; and c) combusting the fuel in the HICE. Also provided are lubricating oil compositions and concentrates for use in a HICE to reduce the propensity for abnormal combustion events.[French]
, et des combinaisons de ceux-ci, iii) au moins un détergent contenant un métal surbasique ayant un indice de base total (KOH/g) supérieur ou égal à 9 et inférieur ou égal à 500 et inclus à un niveau de traitement pour administrer entre 100 et 5000 ppm en poids de métal total et entre 0,15 % en poids et 8,0 % en poids de savon total dans la composition, et iv) la composition d'huile lubrifiante ayant une cendre sulfatée totale inférieure ou égale à 2,5 % en poids, un taux de phosphore total inférieur ou égal à 0,12 % en poids, et un grade de viscosité SAE de 25W-X, 20W-X, 15W-X, 10W-X, 5W-X ou 0W-X, où X représente une chiffre quelconque entre 8, 12, 16, 20, 30, 40, 50 ou 60 ; b) fournir un combustible comprenant de l'hydrogène au MCIH ; et c) brûler le combustible dans ledit MCIH. L'invention concerne également des compositions d'huile lubrifiante et des concentrés destinés à être utilisés dans un MCIH pour réduire la propension à des événements de combustion anormaux.
