  The lubricating oil composition for internal combustion engines of the present invention contains a base oil, a thioheterocyclic compound represented by the following formula (I) (wherein As represents a thioheterocycle; each of R1 and R2 represents a hydrogen atom, an amino group, a C1 to C50 hydrocarbyl group selected from among an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, and an aryl group, or, in the case of a hydrocarbyl group, a C1 to C50 heteroatom-containing group having an atom selected from among an oxygen atom, a nitrogen atom, and a sulfur atom, in the hydrocarbyl group; and each of k, l, m, and n is an integer of 0 to 5), and an aminoalcohol compound having, in the molecule thereof, one or more amino groups and one or more hydroxyl groups, wherein the composition has a phosphorus content (P mass%) and a sulfated ash content (M mass%), based on the total amount of the composition, satisfying any of the following conditions A to C: condition A: P < 0.03, and M < 0.3; condition B: P < 0.03, and 0.3 ≤ M ≤ 0.6; and condition C: 0.03 ≤ P ≤ 0.06, and M < 0.3. The lubricating oil composition of the present invention can considerably reduce the amounts of phosphorus-containing additives and a metallic detergent, while high-temperature detergency and wear resistance are maintained.

  本发明的内燃机润滑油组合物含有基础油、由下式 (I) 代表的硫杂环化合物 (其中 As 代表硫代杂环；R1 和 R2 各代表氢原子、氨基、从烷基、环烷基、烯基、环烯基和芳基中选出的 C1 至 C50 烃基，或者，在烃基的情况下，代表在烃基中具有从氧原子、氮原子和硫原子中选出的原子的含 C1 至 C50 杂原子的基团；且 k、l、m 和 n 中的每一个均为 0 至 5 的整数），以及在其分子中具有一个或多个氨基和一个或多个羟基的氨基醇化合物，其中，基于组合物的总量，该组合物的磷含量（P 质量％）和硫酸盐灰分含量（M 质量％）满足以下条件 A 至 C 中的任一条件：条件 A：P < 0.03，且M＜0.3；条件B：P＜0.03，且0.3≤M≤0.6；条件C：0.03≤P≤0.06，且M＜0.3。本发明的润滑油组合物可以大大减少含磷添加剂和金属清净剂的用量，同时保持高温清净性和耐磨性。

  The invention provides a lubricating oil composition for an engine made of aluminum alloy containing a base oil, a succinimide compound, and a thioheterocyclic compound represented by the following formula (I) and has a sulfur content of 0.10 mass% to 1.00 mass% based on the total amount of the composition, and a phosphorus content and a sulfated ash content, based on the total amount of the composition, falling within specific ranges, and a lubrication method employing the composition. The composition exhibits excellent wear resistance to aluminum alloy sliding parts of engines and can considerably reduce the high-phosphorus ZnDTP content and the metallic detergent content, while excellent wear resistance to aluminum alloy is maintained. The thioheterocyclic compound is represented by the formula: (wherein As represents a thioheterocycle; each of R1 and R2 independently represents a hydrogen atom, an amino group, a C1 to C50 hydrocarbyl group selected from among an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, and an aryl group, or, in the case of a hydrocarbyl group, a C1 to C50 heteroatom-containing group having an atom selected from among an oxygen atom, a nitrogen atom, and a sulfur atom, in the hydrocarbyl group; and each of k, l, m, and n is an integer of 0 to 5).

  本发明提供了一种用于由铝合金制成的发动机的润滑油组合物，该组合物含有一种基础油、一种琥珀酰亚胺化合物和一种由下式（I）表示的硫杂环化合物，并且基于组合物的总量，硫含量为 0.10 质量％至 1.00 质量％，基于组合物的总量，磷含量和硫酸盐灰分含量在特定范围内，以及一种使用该组合物的润滑方法。该组合物对发动机的铝合金滑动部件具有优异的耐磨性，可大大降低高磷 ZnDTP 含量和金属清净剂含量，同时保持对铝合金的优异耐磨性。硫杂环化合物由式表示： (其中 As 代表硫代杂环；R1 和 R2 各自独立地代表氢原子、氨基、选自烷基、环烷基、烯基、环烯基和芳基的 C1 至 C50 烃基，或者，在烃基的情况下，代表在烃基中具有选自氧原子、氮原子和硫原子的原子的含 C1 至 C50 杂原子的基团；且 k、l、m 和 n 中的每一个均为 0 至 5 的整数）。
