Abstract (en)

Coking in and around the injector nozzles of indirect injection compression ignition engines is reduced by means of distillate fuel into which has been blended suitable concentrations of: (a) organic nitrate ignition accelerator, and (b) hydrocarbyl-substituted succinimide or succinamide, or (a) organic nitrate ignition accelerator, (c) hydrocarbyl amine having from 3 to 60 carbons and from 1 to 10 nitrogens, and (d) N,N min -disalicylidene-1,2-diaminopropane, or (b) hydrocarbyl-substituted succinimide or succinamide, (c) hydrocarbyl amine having from 3 to 60 carbons and from 1 to 10 nitrogens, and (d) N,N min -disalicylidene-1,2-diaminopropane. Additive concetrates can be formulated using such additive combinations.
