ABSTRACT:
Coking in and around the injector nozzles of indirect injection compression ignition engines is reduced by means of distillate fuel with which has been blended suitable concentrations of (i) organic nitrate ignition accelerator, and (ii) an additive selected from the group consisting of fuel-soluble aliphatic hydrocarbon-substituted succinimide, succinamide and mixtures thereof. The aliphatic hydrocarbon group contains about 12-36 carbon atoms and is derived from an isomerized straight chain .alpha.-olefin.
Also described are additive mixtures of (i) and (ii) for use in distillate fuels in amounts sufficient to reduce the coking tendencies of such fuels when used in the operation of indirect injection compression ignition engines.
