본 발명은 4차화된 알킬아민 질소 화합물의, 직접 분사 디젤 엔진의 분사 시스템, 특히 커먼 레일 분사 시스템에서 침착의 감소 또는 방지를 위한, 직접 분사 디젤 엔진, 특히 커먼 레일 분사 시스템을 이용하는 디젤 엔진의 연료 소비를 감소시키기 위한, 그리고 직접 분사 디젤 엔진, 특히 커먼 레일 분사 시스템을 이용하는 디젤 엔진에서 출력 손실을 최소화하기 위한, 연료 첨가제 및 윤활제 첨가제, 예컨대 보다 구체적으로, 세제 첨가제로서의 용도; 및 DISI 엔진의 작동을 위한 가솔린 연료용 첨가제로서의 용도에 관한 것이다. Fuel- or lubricant composition comprises at least one reaction product comprising a quaternized nitrogen compound, or its partial fraction, which contains the quaternized nitrogen compound, and is obtained from the reaction product by purification, in a fuel or a lubricant. The reaction product is obtainable by reacting a quaternizable alkylamine containing at least one quaternizable tertiary amino group, with a quaternizing agent comprising e.g. an aliphatic polycarboxylic acid, preferably a dicarboxylic acid, which converts the tertiary amino group into a quaternary ammonium group. Fuel- or lubricant composition comprises at least one reaction product comprising a quaternized nitrogen compound, or its partial fraction, which contains the quaternized nitrogen compound, and is obtained from the reaction product by purification, in a fuel or a lubricant. The reaction product is obtainable by reacting a quaternizable alkylamine containing at least one quaternizable tertiary amino group, with a quaternizing agent comprising (a) an alkyl ester of a cyclo-aromatic or cycloaliphatic mono- or polycarboxylic acid, preferably a mono- or dicarboxylic acid, (b) an aliphatic polycarboxylic acid, preferably a dicarboxylic acid, (c) a hydrocarbyl epoxide optionally in combination with a free acid, or (d) a dialkyl carbonate, which converts the tertiary amino group into a quaternary ammonium group. Independent claims are also included for: (1) the quaternized nitrogen compound; (2) preparing the quaternized nitrogen compound, comprising reacting the quaternizable alkylamine with the quaternizing agent including (a)-(c); and (3) an additive concentrate comprising the quaternized nitrogen compound in combination with further diesel or gasoline fuel additives or lubricant additives.
