Re: Carnot cycle and gasoline octane



I think it should also be pointed out that compression ratios can be
inceased by means other than octane rating. The diesel engine
compresses pure air and then injects fuel. Gasoline engines can do
similar thinds in modified form. A compression ration depends
critically on airflow as well as pure octane.
