C. F. R. Committee Report on 1934 Detonation Road Tests 350094

EVER since the adoption of the C.F.R. Motor Method by the Cooperative Fuel Research Committee on Sept. 12, 1932, periodic checks have been made of the reproducibility of this method. To secure correlation with ratings obtained by this road-test method modifications were made in the laboratory method, which had been evolved by the committee and has been since known as the “research” method.
The object of the 1934 C.F.R. detonation road tests, was (a) to check the validity of correlation between road knock-ratings and laboratory knock-ratings, and (b) to indicate promising paths of research directed toward better mutual adaptation of fuels and engines.
The paper reports on materials and equipment, road-test procedure, supplementary test methods, special reference fuels and results, engine severity-factor and factors affecting fuel-engine relationships. Detonation research is reported upon, and C.F.R. road-test-method specifications are stated in the Appendix.
