The Number One Reliability Mod for the Rotary Engine.

Slow burn-rate or retarded ignition makes the shallow peaks to the right of the actual trace in this depiction.

The closer the peak is to 45 degrees the better.

The area under the curve can also be increase by adding boost

The Rotary is notoriously for its slow burn-rate.
We must find methods to maximize it.

Well, isn't the obvious answer to that question the same thing Mazda did on the r26? Add a third spark source spaced properly....coupled with the added homogeny of the water injection, this would result in a more stable, faster burn rate.

Forgive the question if its a stupid one, but is raising AFR's a bit to increase burn rate out of the question? Again, with the water injection stabilizing the burn rate, do we have enough control to lean out the AFR's enough to speed up the burn rate safely? Wouldn't bringing up the flame speed this way help combat knock?
