    Abstract: The present invention is directed to fuel additive compositions of detergents combined with fluidizers and to hydrocarbon fuel compositions containing these fuel additive compositions. The fuel additive compositions of the present invention combine a Mannich detergent, formed from reaction of an alkylphenol with an aldehyde and an amine, with a fluidizer that can be a polyetheramine or a polyether or a mixture thereof and, optionally, with a succinimide detergent. Fuel compositions containing these fuel additive compositions are very effective in reducing intake valve deposits in gasoline fueled engines, especially when the weight ratio of detergent(s) to fluidizer(s) is about 1:1 on an actives basis.

    Abstract: The operation of marine diesel engines is improved through use of a defined fuel composition, containing one or more additives comprising a methal detergent, a non-metal detergent or both. The fuel is supplied to Diesel engines which operate in a maximum speed range of 1000 rpm (4-stroke engine) respectively 2500 rpm (2-stroke engine). The power output is greater than 200 bph. The cylinder bore is greater than 100 mm (2-stroke engine) while the piston stroke shall be greater than 150 mm (4-stroke engine) respectively greater than 120 mm (2-stroke engine). The metal containing detergent is a neutral calcium sulfonate, salicylate or calcium phenate. The non-metal containing detergent is a hydrocarbyl succinimide.
