This is another very interesting graphic with no explanation given.
Apparently this blows the rich mixture out of the trailing
portion of the combustion chamber. In that case it is similar
to my stratified charge idea.

Either that or it improves the volumetric efficiency.

Either that or it improves the atomization and mixing of the 
fuel injected directly into the rotor housing.

?????

There is an electric air pump in the system. I assume it is
computer controlled and only comes on when needed.
