ADDITIVE COMPOSITION FOR GASOLINE

摘要

PURPOSE:To provide the subject composition capable of remarkably reducing deposits at the intake valves of engines for automobiles by compounding a benzylamine derivative having a specific mol.wt. and an ester as main components. CONSTITUTION:The objective composition comprises (A) a benzylamine derivative represented by the formula (R is an alkyl derived from a polyolefin polymer having a mol.wt. of 500-4500; R' is alkylene; n is 1-10) and (B) an ester [e.g. isodecyl butanoate, di(2-ethylhexyl) adipate or neopentyl glycol di(heptanoate)] as main components and preferably further (C) a lubricant fraction having a viscosity of 3-35mm<2>/S (100 deg.C).
