摘要

The knock-limited performance of 2,2,3,3-tetramethylpentane, 2,4-dimethyl-3-ethylpentane, 2,3-dimethylpentane, and 2,3-dimethyl-2-pentene, individually blended in several base fuels was determined in F-3, F-4, and supercharged 17.6 engines. Temperature sensitivity of the fuels is shown by compression temperature-density curves computed from knock data at five compression ratios on a modified F-4 engine;these curves are also presented for blends of 2,3,4-trimethy1-2-pentene and 3,4,4-trimethyl-2-pentene, whose knock-limited performance was previously reported.
