dont believe everything you read on the internet. There nothing to stroke. A stroke = up and down motion. The rotor spins on an ofset gear. If anything it is a wobble, not a stroke. That article was comparing the action to strokes, not saying that it was actually a 4 stroke engine. A rotary engine has 3 CYCLES, not strokes....
lololol you have proven nothing but the fact that you don't know what you are talking about and you have to use google to supply your facts. That article is either extremely dumbed down so that the average person could vaguely grasp the concept of a rotary engine, or it was written by someone who has never even seen a rotary engine
