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.
Knock-limited engine data are given for 10 alkyl-benzene aromatics, each with base fuels.
Knock-limited tests were conducted with F-4, F-3, and 17.6 small-scale engines and with a full-scale cylinder on blends containing the following purified hydrocarbons: 2,2,3,4-tetramethylpentane, 2,3,3,4-tetramethylpentane, 3,4,4-trimethyl-2-pentene, and 2,3,4-trimethyl-2-pentene.
Reproductions of reports, some declassified, of research done at Aircraft Engine Research Laboratory during World War II. The order of reports does not represent when they were chronologically issued. Reference to the original version of each report is included.
At mild or moderate engine severity, 2,2,3,3-tetramethylpentane blend was highest in knock limit of the paraffins tested, but at severe conditions it was lowest; at severe (F-3) conditions, triptane blend was best.
Knock-limited performance tests of leaded blends of four pure aromatic hydrocarbons and six pure ethers with a base fuel were conducted in a full-scale aircraft-engine cylinder at two operating conditions to determine the antiknock effectiveness of additions of pure compounds to aviation fuels.
