Octane number requirement (ONR) studies were made with eight cars to evaluate effects of temperature, humidity, and altitude; primary reference and 1965 CRC-full-boiling reference fuels were used; temperature and humidity tests were made on chassis dynamometer at sea level, while effect of barometric pressure was studied on road at altitudes up to 6000 ft; regression analysis was used to study correlation between changes in ONR and changes in temperature and humidity; correlations were linear and varied among cars; average changes in ONR were smaller, but in fair agreement with those reported in literature; other findings.
