The present invention relates to novel quaternized polyetheramines and to the preparation thereof. The present invention further relates to the use of these compounds as a fuel and lubricant additive. More particularly, the invention relates to the use of these 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. The invention also provides additive packages comprising these polyetheramines; and fuels and lubricants additized therewith. The invention further relates to the use of these quaternized nitrogen compounds as an additive for gasoline fuels, especially for improving the intake system cleanliness of gasoline engines.
