Field survey has been conducted to determine whether full-throttle acceleration from low engine speed is suitable for road knock tests of fuels in manual-transmission Japanese cars; varying knock levels, fuels, cars, and drives were used on route typical of average Japanese driving; knock did occur most frequently during fullthrottle acceleration from low engine speed; part throttle knock was also encountered; maximum octane-number requirements of four Japanese cars were measured and were as high or higher at 2 in. of mercury manifold vacuum as at full throttle; four Japanese fuels were rated in cars at both throttle settings.
