Good question Tim, I'm certainly no fuel expert, maybe Dave can expand
on that part of his paper.
My understanding is "slow-burn" is just an inherent characteristic of
high-octane gas, ERC's or anybody's, the slow burn is put there to keep
it from detonating in high-compression, high-stress engines. Detonation
of course is the exploding rather than controlled burning of the charge
during the actual power stroke which is from about 15 degrees after top
dead center to about 90-100 degrees after top dead center. Not to be
confused with pre-ignition which is a whole other subject. Cheers Bill
