just a quick look at combustion. gasoline is flammable in air from 1.4% to 7.4%, about 55:1 to 13.3:1. 4 ways to put out a fire are stop the fuel, stop the air, stop the heat and add a chemical that suppresses the combustion process. combustion in the piston chamber of an engine uses the fuel and air. the piston going down will take heat away. octane boost will be the chemical suppressant. for the most efficient combustion the pressure has to build to max atdc before very much piston movement takes place. the faster the better. the faster the burn, the better. higher compression is also better.
