KNOCK - LIMITED PERFORMANCE of Several Automobile Engines 480207
REPORTED here is a program designed to give the knock-limited performance at full-throttle operation of 24 automobiles. Various models were used in the test work, including four 1942 models that were converted to higher than normal compression ratios to simulate a possible future trend.
Curves have been developed to show how octane number correlates with the performance of these standard and special engines as they are installed in automobiles.
