摘要：
Lubricating oil composition for use in diesel engines which comprises, in the base oil, not more than 0.3% by mass of sulphated ash, from 0.01 to 0.2% by mass of nitrogen in succinimides, from 0.05 to 0.12% by mass of zinc in zinc dithiophosphates, from 0.02 to 0.3% by mass of nitrogen in amine-based anti-oxidants, and from 0.01 to 0.08% by mass of boron, which further has a total value of [(zinc amount in zinc dithiophosphates) x (nitrogen amount in succinimides)] and [(zinc amount in zinc dithiophosphates) x (nitrogen amount in amine-based anti-oxidants) ] as regards the aforementioned of from 0.015 to 0.06, and which does not contain salicylate, phenate or sulphonate metallic detergents. The intention is to obtain a lubricating oil composition for use in diesel engines which does not contain a metallic detergent yet maintains excellent engine (piston) detergency while preventing DPF clogging, and which reduces valve-train wear.
摘要（中）：
用于柴油机的润滑油组合物，其在基油中不超过0.3质量％的硫酸盐灰，0.01〜0.2质量％的琥珀酰亚胺中的氮，0.05〜0.12质量％的锌 二硫代磷酸盐，胺系抗氧化剂中的氮含量为0.02〜0.3质量％，硼的含量为0.01〜0.08质量％，其总值为[（二硫代磷酸锌的锌量）×（氮含量 琥珀酰亚胺）]和[（二硫代磷酸锌中的锌量）×（胺系抗氧化剂中的氮量）]为0.015〜0.06，不含水杨酸盐，酚盐或磺酸盐金属洗涤剂。 其目的在于获得不含金属洗涤剂的柴油发动机用润滑油组合物，同时保持优异的发动机（活塞）去污力同时防止DPF堵塞，并且减少阀门磨损。
