Title
(EN) MARINE LUBRICANT FOR FUEL OIL HAVING HIGH AND LOW SULPHUR CONTENTS
(FR) LUBRIFIANT MARIN POUR FIOUL A BASSE OU HAUTE TENEUR EN SOUFRE
Abstract
(EN)
The present invention relates to a cylinder lubricant for a two-stroke marine engine that uses bolt high sulphur content fuel oil and low sulphur content fuel oil. The invention relates to a cylinder lubricant having a BN, determined according to the ASTM D-2896 standard, that is higher than or equal to 40 mg of potash per gram of lubricant, and containing a lubricant base oil for marine engine and at least one overbased detergent containing alkaline or alkaline-earth metals, characterised in that it further contains an amount of 0.01 to 10 wt % and preferably 0.1 to 2 wt %, relative to the total weight of the lubricant, of one or more compounds (A) selected from primary, secondary or tertiary monoalcohols having a saturated or unsaturated linear or branched alkyl chain containing at least 12 carbon atoms. The lubricant has a sufficient neutralising effect on the sulphuric acid generated during the combustion of fuel oils with a high sulphur content, while limiting the formation of deposits when using fuel oils having a low sulphur content.
(FR)
La présente invention concerne un lubrifiant cylindre pour moteur marin deux temps utilisable à la fois avec des fiouls à haute teneur en soufre et des fiouls à basse teneur en soufre. Elle se rapporte à un lubrifiant cylindre ayant un BN déterminé selon la norme ASTM D-2896 supérieur ou égal à 40 milligrammes de potasse par gramme de lubrifiant, comprenant une huile de base lubrifiante pour moteur marin et au moins un détergent surbasé à base de métaux alcalins ou alcalino terreux, caractérisé en ce qu'il contient en outre une quantité de 0,01 % à 10 % en poids, préférentiellement de 0,1 % à 2 % en poids par rapport au poids total du lubrifiant, d'un ou plusieurs composés (A) choisis parmi les mono-alcools primaires, secondaires ou tertiaires dont la chaîne alkyl est saturée ou insaturée, linéaire ou ramifiée et comprend au moins 12 atomes de carbone. Ce lubrifiant présente un pouvoir de neutralisation suffisant vis-à-vis de l'acide sulfurique formé lors de la combustion de fiouls à haute teneur en soufre, tout en limitant la formation de dépôts lors de l'utilisation de fiouls à basse teneur en soufre.
