Default Re: Dolphin powered bike... a different kind of 2 stroke

It's still a 2 stroke, the 2nd cylinder is a charge chamber. It just doesn't utilize crankcase compression. If it were a 4 stroke it would have valves. The only valve this engine has is a check valve above the power cylinder.

And I did a little research on that design. There is apparently only one left in existence, and it's not on his bicycle.
