<p>COMPRESSION IGNITION FUEL COMPOSITIONS 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 (a) organic nitrate ignition accelerator, (b) copolymer of an alpha-olefin having from 8 to 30 carbon and an N-substituted maleimide wherein the N-substituents are organic radicals having from 3 to 60 carbons and from 1 to 5 amine nitrogens, said copolymer having from 4 to 20 repeating olefin-maleimide units, and (c) hydrocarbyl amine having from 3 to 60 carbons and from 1 to 10 nitrogens.</p> |
