550k is a low combustion temperature. “Modern military jet engines, like the Snecma M88, can see turbine temperatures of 2,900 °F (1,590°C).” https://en.m.wikipedia.org/wiki/Turbine_blade

That’s like ~1850k assuming 2900F was rounded.

Absolutely. But I read the comment as complaining about efficiencies of automobile engines, not modern military jet engines. The combustion temperature of gasoline is 553K.

Ignition temperature is just the point when something starts to burn, it has nothing to do with the temperature inside an engine after ignition.
