Hi!: I guess that with Mazda US20160084158A1 patent application arrangement, an added heat pipe system in the housing, to make temperatures lower and more uniform, the hotter housing part being in the bottom, heat pipe transporting heat to the upper zone, may help in having a more efficient engine.

Thanks, regards, + Salut

The rotary does not need heat pipes to cool it. It runs too cool as it
is. 100 F cooler than a piston engine. A warmer engine will reduce
the fuel burn.
