DIESEL FUEL COMPOSITIONS

摘要

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 concentration of: (a) organic nitrate ignition accelerator, and (b) the condensation product of a phenol, preferably a high molecular weight alkylphenol, and aldehyde and an amine having a H-N< group. Also described are additive mixtures of (a) and (b) 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.
