One can screw around with injectors and intake heat until one is blue in 
the face but one is wasting ones time. Unburned fuel is a very small part of
the overall efficiency  loss of the engine less than 10%. The rotary combustion 
chamber will never be as good as a cylinder let alone a sphere.

On the other hand if one focuses on the single largest potential part of
the lost heat equation, namely the 36% exhaust heat, the aircraft engine  
world market will beat a path to ones door. The technology is 60 years old for
*&^% sakes. Sheesss! TURBO COMPOUND IS THE ANSWER!

The downfall of the old turbo compound engine was the exhaust valve.
Pray tell me; where is the exhaust valve in a rotary?
This means Lycoming and Continental cannot copy you as their
exhaust valves are now at the absolute limits of their durability.

For an aircraft engine forget the the variable ratio part of this
friction drive gear box. Just optimize it for cruise RPM since you have 
a constant speed prop.

This is the umpteenth zillion time I have mentioned turbo compound on this
newsletter.
