A detailed analysis has been made on the Cetane Scale presently used to rate the auto-ignition quality of fuels. The effect of the increase in temperature and pressure, as a result of increasing the compression ratio, on the ignition delay has been theoretically and experimentally analyzed. It has been found that the ignition delay is more sensitive to air temperature than air pressure. The sensitivity increases with the drop in the cetane number of the fuel. Many techniques have been examined to modify the present cetane scale. A modified scale has been developed by raising the inlet temperature from 150 F to 350 F without changing the rest of the rating technique. The modified scale is very effective in extending the scale to zero cetane number and is able to rate the low ignition quality fuels. (DePo)
