318 MAX fuel economy builds?

He's right, liquids don't burn in the cylinder. The finer the droplets are the better the homogenization is and as a result the burn is better. SO if your engine requires a lot of timing what does that tell you?
David Vizard covers fuel atomization where large droplets DO work with specific (some would label insufficient) combustion chambers. His experience with this subject came from Mini (Cooper?) racing in the 60's or 70's. One combustion chamber needed large droplets of fuel for the most power output of that particular engine.
