The present invention relates to a marine engine lubrication. A trunk piston marine engine lubricant comprises in respective minor amounts (A) an overbased metal hydrocarbyl-substituted hydroxybenzoate detergent system, and (B) a hydrocarbyl-subsituted succinic acid anhydride, preferably made by halogen- or radical-assisted functionalization processes, where the ratio of succinic anhydride to hydrocarbyl chains is in the range of 1.4 to 4. The lubricant, when used to lubricate such an engine fuelled by heavy fuel oil, exhibits improved control of asphaltene precipitation and deposition on engine surfaces.

    트렁크 피스톤 선박 엔진 윤활제는, 각각 소량의 (A) 과염기성 금속 하이드로카빌-치환된 하이드록시벤조에이트 세정제 시스템, 및 (B) 하이드로카빌-치환된 석신산 무수물로서, 바람직하게는 할로겐- 또는 라디칼-보조 작용성화 공정에 의해 제조되고, 하이드로카빌 쇄에 대한 석신산 무수물 기의 비가 1.4 내지 4 범위인, 하이드로카빌-치환된 석신산 무수물을 포함한다. 상기 윤활제는, 중질 연료유가 연료로 보급되는 상기 엔진을 윤활시키기 위해 사용되는 경우, 엔진 표면상에서의 아스팔텐 침전 및 침착의 개선된 제어를 나타낸다.
