Definitions

  • the invention relates to compression ignition fuel compositions and additive mixtures of organic nitrate ignition accelerator, hydrocarbyl amine and N,N'-disalicylidene-1,2-diaminopropane, ir. amojnts sufficient to resist the coking tendencies of compression ignition fuel compositions when used in the operation of Indirect injection diesel engines.
  • Throttling diesel nozzles have recently come into widespread use in indirect injection automotive and light-duty diesel truck engines, i.e., compression ignition engines in which the fuel is injected into and ignited in a prechamber or swirl chamber. In this way, the flame front proceeds from the prechamber into the larger compression chamber where the combustion is completed. Engines designed in this manner allow for quieter and smoother operation.
  • the Figure of the Drawing illustrates the geometry of the typical throttling diesel nozzle (often refered to as the "pintle nozzle").
  • This invention provides distillate fuel for indirect injection compression ignition engines containing a combination of (a) organic nitrate ignition accelerator, (b) hydrocarbyl amine having from 3 to 60 carbons and from 1 to 10 nitrogens and (c; N,N-disalicylidene-1,2-diaminopropane, the combination being present in an amount sufficient to suppress and preferably to minimize coking, especially throttling nozzle coking, in the prechambers or swirl chambers of indirect injection compression ignition engines operated on such fuel.
  • additive fluid concentrate for use in distillate fuels and which contains a combination as defined above.
  • a still further embodiment of the present invention is a method of inhibiting coking. especially throttling nozzle coking, in the prechambers or swirl chambers of an indirect injection compression ignition engine, which comprises supplying said engine with a distillate fuel containing a combination as defined above, said combination being present in an amount sufficient to suppress and preferably to minimize such coking in an engine operated on such fuel.
  • a feature of this invention is that the combination of additives utilized in its practice is capable of suppressing coking tendencies of fuels used to operate indirect injection compression ignition engines. Such behavior was exhibited in a series of standard engine dynamometer tests conducted as described in the Example hereinafter.

  • Primene 81 R A particulariy preferred hydrocarbyl amine is available commercially from the Rohm and Haas Company under the designation Primene 81 R.
  • the Primene 81 R is believed to be a mixture of primary aliphatic amines in which the aliphatic groups are predominantly C 12 and C 14 tertiary alkyl groups.
  • the fuels of this invention should contain at least 1.5 to 40 PTB (0.00429 to 0.1143 grams/liter) of component (b), the hydrocarbyl amine.
