1941 CFR ROAD DETONATION TESTS - Further Experience with New Methods (Compiled from Report of the Cooperative Fuel Research Committee) 420122

The cooperative road tests carried out during 1941 have added considerable information and experience to that already existing on the subject of road detonation testing.
Extensive data were obtained on the fuel requirements of the 1940 and 1941 models of the three most popular cars. Corresponding data were obtained on the knocking characteristics of current gasolines representing the bulk of the sales volume in various parts of the United States.
On account of large variations in octane-number requirement among different cars of the same make - due to differences in ignition timing, combustion-chamber deposit, and other causes - and on account of variations in commercial gasolines, it has been necessary to use statistical methods of analysis in the appraisal of fuel and engine relationships.
These methods of analysis have been applied in a number of ways, and have proved very useful. For this reason, the continuance of cooperative activity in compiling current statistical information annually on fuels and car requirements is recommended.
