This is mostly correct, except the heat that causes the detonation comes from the retained heat in the combustion chamber area.Assumption: Temperature is the cause of pre-ignition / detonation of a given fuel; CR, DCR, all the other indicators have rough coorelation to pre-ignition /detonation
Or to say it another way: the temperature of the fuel being raised beyond the point at which the fuel spontaneously combusts is the CAUSATION of pre-ignition; the other factors are merely COORELATION to what we should actually care about.
Then it sets off the mixture prematurely before the spark plug fires.
With a correctly working coating, the surrounding combustion chamber would be cooler than with a non-coated one.
All the extra heat from the correct actual combustion process would push harder on the piston for more power, and the rest would go out the exhaust like now.
The gains would be more than 10 HP probably?
2/3rds of the actual combustion process of gasoline is wasted heat. Gaining even 10% of that would be huge?
