Rotary Cylinder Engine
with One Cylinder and Two Pistons
NOTE: One Rotary Cycle -360°.  The smallest commercial version
will be two Rotary Chambers.  You should read the Detailed
Description in Section III of the Prospectus for Hydrogen-
Powered True-Rotary Engine by Douglas R. Bastian to better
understand this dynamic graphic.
NOTE: This Graphic does not show any detail of how the rotating
pistons change velocity in their rotary cycle. The Otto Cycle
Engine (the one in your car, lawnmower, etc.) uses a principle by
which the pistons continuously reverse their direction for a 720°
cycle.  The animation of this rotary motion & actuation of the two
revolving plates and using only one chamber is a simplified
version and there are other  scenarios being developed.  
Generally, for transportation use, a minimum of two cylinders will
be used.
