| 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 concentrations of: (a) organic nitrate ignition accelerator, and (b) an N-(2-hydroxyalkyl)monoalkanolamine or an N-(2-hydroxyalkyl)dialkanolamine. 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.
