description FUEL COMPOSITIONS CONTAINING DEPOSIT CONTROL ADDITIVES Fuel compositions for internal combustion engines are provided which contain deposit control additives which maintain cleanliness of intake systems without contributing to combustion chamber deposits. The additives are polyoxyalkylene carbamates comprising a hydroxy- or hydrocarbyloxy-terminated polyloxyalkylene chain of 2-5 carbon oxyalkylene units bonded through an oxycarbonyl group to a nitrogen atom of polyamine having from 2 to 10 amine nitrogens and from 2 to 40 carbons with a carbon:nitrogen ration between about 1:1 and 10:1.
