I watch the "nerdy" periodic videos on you tube. I have confused some with the term "super stoich". It is simply a mixture of fuel and air returning maximum explosion in an internal chamber..but it can be external, like the gas plant explosion in middletown ct recently. For a car, realtime draft hjard set for the engine is the only real super stoichs, and they are getting more an more rare..
anyway, check this simple experiment out. The methane fuel, the air, awaiting its natural super stoich from a can.
a carb can do this with low compression. Can anyone guess why fuel injection will never be an ecomodded winner?
