Some of you may remember the discussions of the motor built into the wheel whereas the motor turns with the wheel. Can you imagine how that would work ?
We often make reference to the WW1 biplanes which had the propellor bolted to the motor and the motor bolted to the airplane. Thus the prop and engine housing served like a flywheel to keep the inertia going. So could this work in a motorized bicycle wheel ?
Well, if you want a brain teaser..........just click that link to the animated motor in the first post and go to the bottom green box and click on the word "engines". You'll see a window come up with a list of different types of engines.(all of which are animations by the way)
In the first group "Internal Combustion".....there is a "GNOME" cycle engine. It has a poppet valve in the piston for intake and one in the head for the exhaust. Watch it turn and try to understand it.
And remember....these things burnt a mix of Castor Oil mixed with Gasoline.
