Concerning to antiknock properties, we measured bunning velocity of 1. n-heptane, 2. i-octane, 3. benzene, 4. toluene, 5. methyl-alcohol, 6. ethyl-alcohol, 7. diethyl-ether, 8. di-i-propyl-ether, 9. acetone and 10. carbon bisulphide by the burner method. The maximum burning velocity are as the following order : 10>5>3>6>7>1>8>4,9>2 Ethyl fluid or methyl nitrate are mixed in compounds 1, 2, 3, 5 and 8, their ammounts are 0.4% or 1.0% (vol.) respectively and they are enough to change knocking tendency, but they do not change the burning velocity. The flame speed at high pressure and temperature are also checked by CFR-Engine combustion chamber, and the same order as atmospheric burning velocity are found. From the fact that the burning or flame velocity are not ranged in the order of their knocking properties, and are not effected by knock supprcssor or inducer, the knocking has no direct connection to the flame speed.
