The engine is my patented design, and this is to get busy engineers to read and understand it on one page. A mechanical drawing for you to copy is attached. It must rotate every ten seconds. In the bottom of the inlet port is a By-Pass valve (BP). This is shown with its lever in position 1, and is fully open. In position 2, it is half open. In position 3, it is closed. These positions must be shown for 5 engine rotations each, and are idle, cruise and full power. In position 1, both the black triangles in the exhausts are shown in their down position. In position 2, they must flip up half way, and in position 3, they must flip right up to clear the exhaust gases. Above the BP valve is a pivoting inlet valve. It is a rigid petal and must flip open by the suction of the RH rising piston, and then open by the LH rising piston. See this video [login to view URL] . to understand.
When these mechanicals are done, we must do the induction (fresh air) down the inlet port past the open petal, filling under the rising piston. When the piston gets to the top, a spark ignites the air and the hot gas drives the piston down, while compressing the fresh charge beneath it, trapped by the closed inlet valve and is released through the transfer ports you see outlined, from under to above the piston for the next compression and combustion at the top. This gas movement is shown by little moving arrows. These will be light blue under induction, darkening to darker blue under compression, and turning red during combustion and exhausting out of the exhausts. Maybe red for full power, orange for cruise, and yellow for idle.
