Prechamber Mod "Flame" Front
Prechamber Mod "Flame" Front
I don't have to much time to think about this tonight. But a few comments. IDI engines always have higher compression. Cummins is about 17:1, Mercedes about 21:1. Perhaps to get the pressure higher in the pre chamber? It would seem to me that, when the piston is in the compression stroke the pre chamber may well be at a lower compression, at running speed. What would happen to the Cummins if the compression where raised to the same as the Mercedes?
It would seem that the pre chamber controls the burn rate in a way that would allow higher compression, without damaging pressure spikes.
Do we know if an IDI engine is capable of higher speed because of the pre chamber or the higher compression?
