Re: Ocatane Rating
By the IUPAC definition, Octane is an alkane with 8 carbon atoms.
Oh, you mean the other octane. Basically it's a measure of how well a fuel resists compression ignition. It is not a measure of how volatile a fuel is nor is it a measure how much energy is "in" the fuel (its delta-Hc or heat of combustion). For more info on octane and the chemistry of gasoline, I'm sure Wikipedia has a great writeup on it. Last edited by trz1000; 08-13-2010 at 06:39 PM. Reason: grammar |
