  • Lubricating oil compositions containing dispersant additives
    Patent number: 4329240
    Abstract: Fuel compositions for internal combustion engines are provided containing deposit control additives which maintain cleanliness of intake systems without contributing to combustion chamber deposits. The additives are hydrocarbylpoly(oxyalkylene) aminocarbamates comprising a hydrocarbyl-terminated poly(oxyalkylene) moiety composed of 2-5 carbon oxyalkylene units and one or more 9-30 carbon oxyalkylene groups. Certain additives also find use as dispersants in lubricating oils.
