Knock-Limited Performance of Fuel Blends Containing Aromatics V - N- propylbenzene, N-butylbenzene, isobutylbenzene, M-xylene, and 1-isopropyl-4- methylbenzene

摘要

Results are reported of knock-limited tests of five aromatics, each individually blended with selected base fuels and tested with and without TEL, using 17.6, F-4, and F-3 small-scale engines. The five aromatics rated in the following order of decreasing antiknock effectiveness at fuel/air ratio 0.10: m- xylene, 1-isopropyl-4-methylbenzene, n-propylbenzene, isobutylbenzene, and n- butylbenzene.
