Abstract: A METHOD OF REDUCING INTAKE VALUE DEPOSITS FORMED IN A SPARK IGNITION GASOLINE-FUELED INTERNAL COMBUSTION ENGINE IS DISCLOSED. THE METHOD FEATURES THE USE OF GASOLINE CONTAINING A DEPOSIT REDUCING AMOUNT OF A HIGH MOLECULAR WEIGHT ALKYL AROMATIC HYDROCARBON OR MIXTURE OF ALKYL AROMATIC HYDROCARBONS. THE GASOLINE COMPOISTIONS AND GASOLINE ADDITIVE CONCENTRATES ARE ALSO DISCLOSED.

Abstract: THE DISPERSANT AND DETERGENT PROPERTIES OF LUBRICATING OILS AND LIQUID HYDROCARBON FUELS SUCH AS GASOLINE ARE IMPROVED BY ADDITION OF A SMALL BUT EFFECTIVE AMOUNT OF AN N-HYDROCARBYL-SUBSTITUTED NITRILOTRIS ETHYLAMINE. THE HYDROCARBYL GROUP IS PREFERABLY A POLYOLEFIN GROUP, SUCH AS A POLYBUTENE GROUP, HAVING A MOLECULAR WEIGHT OF FROM ABOUT 300 TO 20,000 MORE PREFERABLY FROM 500 TO 2,000.

Abstract: A method of reducing intake valve deposits formed in a spark ignition gasoline-fueled internal combustion engine is disclosed. The method features the use of gasoline containing a deposit reducing amount of a high molecular weight alkyl aromatic hydrocarbon or mixture of alkyl aromatic hydrocarbons. The gasoline compositions and gasoline additive concentrates are also disclosed.

Abstract: GASOLINE COMPOSITIONS CONTAINING NORMALLY LIQUID NONAROMATIC OLEFIN HYDROCARBONS HAVING AN AVERAGE MOLECULAR WEIGHT OF FROM 350 TO ABOUT 1500; THE COMPPOSITION ARE CHARACTERIZED BY SUBSTANTIALLY REDUCING THE UNDERHEAD INTAKE VALVE DEPOSIT FORMATION WHEN USED AS FUELS IN A SPARK IGNITION, INTERNAL COMBUSTION ENGINE. PREFERRED OLEFIN HYDROCARBONS ARE THOSE PREPARED BY FRIEDEL-CRAFTS POLYMERIZATION OF A MIXTURE OF MONOOLEFINS WITH CARBON NUMBERS RANGING FROM ABOUT C12 AND HIGHER.
