Quench?

Thanks, Pat, that is a great concise treatise on combustion chamber design. From a purely theoretical power production standpoint, is it better to have instantaneous combustion throughout the entire combustion chamber or to have a moving flame front type of combustion event? (Of course, this is purely theoretical because there is no pracitcal way to get instantaneous complete combustion inside the chamber - does a diesel engine have an instant combustion event or does it ingite in a "hot spot" and propagate from there?)
