The invention relates to novel acid-free quaternised nitrogen compounds and to the production and use thereof as fuel and lubricant additives, such as in particular as detergent additives, as wax anti-settling additives (WASA) or as additives for reducing internal diesel injector deposits (IDID). The invention further relates to additive packages containing said compounds and to fuels and lubricants containing said additives. The invention additionally relates to the use of said acid-free quaternised nitrogen compounds as fuel additives for reducing or preventing deposits in the injection systems of direct-injection diesel engines, in particular in common rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, in particular of diesel engines having common rail injection systems, and for minimising the power loss in direct-injection diesel engines, in particular in diesel engines having common rail injection systems. |
