Is it possible to have an engine with enough pistons to not need a flywheel? I know it's not really a feasible proposition, but I just want to know if it is theoretically possible? If so, how many would it need? If the crank turns 360°, how many times do you need a piston to "power" the crank to eliminate the flywheel? Would you need 360 (one every degree) or could you get away with less?
These are the random thoughts I come up with...
