First of all (and I know this is not the place I'm supposed to introduce myself,) I'd like to say hi to the forums. Now onto my question. For the past few weeks, I've been thinking about an idea I had. That idea was to use pure oxygen to oxidize a combustion reaction in an engine. I'm sure most, if not all, people on this form understand Guy-Lussac's law. I know that as the oxygen content of a fuel/ oxygen mixture is increased, the auto ignition temperature decreases (please correct me if I'm wrong.). Guy-Lussac's law states that p1/t1=p2/t2, meaning that temperature will increase with pressure. In order to actually design the engine, I need to know the auto ignition temperature of gasoline in a pure (or nearly pure) oxygen atmosphere, otherwise I would end up with knocking. Thanks.
