Abstract: FUEL COMPOSITIONS FOR INTERNAL COMBUSTION ENGINES, COMPRISING A PRINCIPLE AMOUNT OF A LIQUID HYDROCARBON FUEL AND AN AMOUNT, WHICH HAS A CLEANING EFFECT, OF AT LEAST ONE PROPOXYLATE ADDITIVE OF THE FORMULA I WHEREN IS AN INTEGER FROM 10 TO 20 AND R¹ IS STRAIGHT-CHAIN OR BRANCHED C8-C18-ALKENYL, IF REQUIRED IN COMBINATION WITH AT LEAST ONE DETERGENT ADDITIVE, E.G. A POLYALKYLAMINE ADDTIVE OF THE FORMULA II R²-NH₂ (II) WHERE R² IS A STRAIGHT-CHAIN OR BRANCHED POLYALKYL RADICAL HAVING A NUMBER AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 500 TO ABOUT 5000,AND FUEL ADDITIVE COMPOSITIONS WHICH CINTAIN PROPOXYLATES OF THE FORMULA I AND, IF REQUIRED, FURTHER ADDITIVES, SUCH AS THE AFOREMENTIONED POLYALKYLAMINES OF THE FORMULA II, AS INTAKE VALVE CLEANERS.

Abstract: Reaction products of polyisobutenes having an average degree of polymerization P of from 10 to 100 and a content E of from 60 to 90% of double bonds which can react with maleic anhydride, E=100% corresponding to the theoretical value for the case where each molecule of the polyisobutene has such a reactive double bond, with oxides of nitrogen or mixtures of oxides of nitrogen and oxygen, are suitable as additives for fuels, in particular for gasoline engines, and for lubricants.
