Default Baffled top piston diesels.

I have always considered that the baffle on any piston top will be the hottest place in the entire combustion chamber and when used in a model diesel will cause localised pre- ignition well before the piston rises to its correct place before TDC .

And its not a matter of simply reducing compression to retard the ignition to remedy this problem because to any attempt to wind back the comp as far as the baffle will advance it results in a very poor state of tune.

Does anyone see this differently?

And is it the reason that baffle top piston engines are not more readily adopted for model diesel use?

Thanks.
