Default Auto-ignition temps (of hydrocarbons) vs. pressure

So octane ratings for petrol must be targeted at a specific compression
ratio.

Bruce, if you're interested, why don't diesel engines have indefinitely high
compression ratios? Higher compression would result in a deeper
(volume-wise) thermodynamic cycle, hence more efficient. After all, the fuel
is injected only after the compression cycle.
