内燃机用润滑油组合物
摘要：
本发明提供一种高温沉积性能良好并且低磨耗特性优异的长寿命节油型发动机油。本发明的内燃机用润滑油组合物的特征在于，其是在矿物油以及/或者合成系基础油中，调配以金属成分计为0.12质量％～0.24质量％的碱土金属系清洁剂、以磷(P)成分计为0.005质量％～0.070质量％的至少含有二烷基二硫代磷酸锌(ZnDTP)的P系添加剂、以及以钼(Mo)成分计为0.030质量％～0.075质量％的二硫代氨基甲酸钼(MoDTC)而制成的，且所述P系添加剂的P成分和所述MoDTC的Mo成分满足下式(1)所表示的条件：0.5×P+Mo≤0.075(1)；[式中，P表示润滑油组合物中P系添加剂的P成分的比例(质量％)，Mo表示润滑油组合物中的MoDTC的Mo成分的比例(质量％)]。
摘要（英）：

The present invention provides a kind of fuel-efficient engine oil with good high-temperature deposition performance, low wear characteristic and long service life. The lubricating oil composition for internal combustion engines of the invention is characterized in that the lubricating oil composition is produced by adding certain amount of alkaline earth detergent containing 0.12 to 0.24 percent metal ingredient by weight ratio, adding certain amount of P-type additive at least including zinc dialkyl dithio (ZnDTP) containing 0.005 to 0.070 percent P by weight ratio and adding certain amount of molybdenum dithiocarbamate (MoDTC) containing 0.030 to 0.075 percent Mo by weight ratio to mineral oil and/or synthesized base oil. The P content in the P-type additive and the Mo content in MoDTC satisfy the following formula (1): 0.5*P + Mo¿Q0.075 (1 ); [wherein, P represents the P content in the P-type additive of the lubricating composition (wt%); Mo represents the Mo content in MoDTC of the lubricating composition (wt%)].
