The present invention relates to novel acid-free quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive, as a wax antisettling additive (WASA) or as an additive for reducing internal diesel injector deposits (IDID); to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these acid-free quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct-injection diesel engines, especially in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, especially of diesel engines with common-rail injection systems, and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems.
本发明涉及新型无酸季铵化氮化合物,其制备方法以及作为燃料和润滑油添加剂的用途,更具体地作为清洁剂添加剂、蜡抗沉降添加剂(WASA)或用于减少内燃机喷油嘴沉积物的添加剂(IDID);包含这些化合物的添加剂配方;以及添加了这些化合物的燃料和润滑油。本发明还涉及将这些无酸季铵化氮化合物用作燃料添加剂,以减少或预防直喷柴油发动机喷油系统中的沉积物,特别是在共轨喷油系统中,在直喷柴油发动机中降低燃料消耗,特别是在具有共轨喷油系统的柴油发动机中,并最小化直喷柴油发动机中的功率损失,特别是在具有共轨喷油系统的柴油发动机中。
