A correlation of the effects of compression ratio and inlet-air temperature on the knock limits of aviation fuels in a CFR engine 2

Description: Report presenting the knock-limited performance of nine fuels comprising isolated members of four classes of hydrocarbons in the form of three-dimensional plots of fuel-air ratio, compression temperature, and compression-air density.

The knock-limited performance of several miscellaneous fuels blended with a base fuel

Description: Report presenting investigations to determine the knock-limited performance of blends of 90 percent by volume AN-F-28, Amendment-2 fuel, and 10 percent by volume of the following fuels: tert-amyl alcohol, 2,6-dimethyl-1, 4-dioxane, methyl tert-butyl ether, methyl tert-butyl ketone, methyl isobutyl ketone, mesityl oxide, acetone, and diisopropyl ketone.

Knock-limited performance of pure hydrocarbons blended with a base fuel in a full-scale aircraft-engine cylinder 2: twelve aromatics

Description: Report presenting an investigation of the knock-limited performance of leaded blends of 12 pure aromatic hydrocarbons in a full-scale aircraft-engine cylinder at CRC simulated cruise and take-off conditions to determine the antiknock effectiveness of additions of pure compounds to aviation fuels. Results indicated that all of the hydrocarbons increased the knock limit of the base fuel except for 2 of them.

Knock-limited performance of pure hydrocarbons blended with a base fuel in a full-scale aircraft-engine cylinder 3: four aromatics, six ethers

Description: Report presenting knock-limited performance tests of leaded blends of four pure aromatic hydrocarbons and six pure ethers with a base fuel in a full-scale aircraft-engine cylinder at two operating conditions to determine the antiknock effectiveness of additions of pure compounds to aviation fuels.

The effect of ethylene dibromide on the knock-limited performance of leaded and nonleaded S reference fuel

Description: Report discussing testing to determine the effect of ethylene dibromide on the knock-limited performance of S reference fuel. An increase in ethylene-dibromide content did appear to decrease the knock-limited performance of the fuel up to a certain point and at all but the extremes of fuel-air mixtures.

F-3 and F-4 engine tests of several high-antiknock components of aviation fuel

Description: Report discussing testing on triptane, hot-acid octane, diisopropyl, neohexane, mixed xylenes, cumene, benzene, toluene, and methyl tert-butyl ether in several blends to determine their knock-limited performance data in F-3 and F-4 engines at standard operating conditions. All of the blending agents examined were found to be usable, with concentrations varying depending on various thermodynamic properties.

Effect of Water Injection on Knock-Limited Performance of a V-Type 12-Cylinder Liquid-Cooled Engine

Description: Report presenting an investigation conducted to determine the effect of water injection on the knock-limited performance of a V-type 12-cylinder liquid-cooled engine. The knock-limited performance tests were made at an engine speed of 3000 rpm with carburetor-air temperatures of 158, 101, and 50 degrees Fahrenheit at water-fuel ratios of 0, 0.2, 0.4, and 0.6.
