I just wanted to pass on some pictures of a Glow engine I picked up some time ago that I bet No one has seen before. Actually, I hope some one has seen one since I would like to know more about how it works. What I can tell you about it is the fact that the 2 pistons look like a Bow Tie. As one rotates up, the other rotates down on the other side. As they Wobble up and down they turn the crank shaft.
