The invention provides a lubricating oil additive for internal combustion engines which additive enables to prepare a lubricating oil composition for internal combustion engines having an enhanced base number without impairing the performance of an exhaust gas treatment apparatus such as a PM trap or an oxidation catalyst member; a lubricating oil additive composition for internal combustion engines; and a lubricating oil composition for internal combustion engines containing the lubricating oil additive composition.
The invention is directed to a lubricating oil additive composition for internal combustion engines including a succinimide compound represented by formula (1) :
(wherein R1 represents a C6-C30 alkenyl group or alkyl group; each of R1, R8, R9, and R10 represents hydrogen or a C1-C3 alkyl group; q is an integer from 2 to 4; n is an integer from 0 to 3; r is an integer from 2 to 4; and A represents an amino group or an N-piperazyl group), or a boron-introduced product thereof; and to use thereof.
本发明提供了一种内燃机润滑油添加剂,该添加剂能够制备具有增强基数的内燃机润滑油组合物,而不会损害废气处理装置(例如 PM 捕集器或氧化催化剂部件)的性能;一种内燃机润滑油添加剂组合物;以及一种含有该润滑油添加剂组合物的内燃机润滑油组合物。
