Rotary Rotational Demonstration

A little video for all those folks that refuse to accept the "3:1" principal of planetary motion inside the Mazda Rotary Engine.
EDIT: For you people that are hung up on my comment at the end of the video, I suspect you are probably one of those at which the comment directed.
It never ceases to amaze me how many people will see this video and continue to argue that there is some other relationship other than 3:1 between the inside and outside worlds of this motor.

Who is that idiot calling an idiot?

Must be the Birkenstock company.

( Thought I smelled patchouli )

@jungledave7080 - Those are Keens. They are for desert hiking.

WTF is patchouli?

@doktorbimmer Ahhh, I can see the logic in that!. Thanks!

[doktorbimmer]

@buddyl962 No, actually its not 4-cycle at all, if it has a power cycle once per revolution that makes it a 2-cycle motor, don't forget there are intake and exhaust cycles that are happening at the same time.. just like any other 2-cycle, it just takes place outside of the combustion segment of the housing.

@jesuitraiders Yes, and the idiots should stop calling it a rotary too, doesn't matter who makes it.. its still a Wankel motor. Cheap ass Mazda can't affort to use the trademark name? oh, well.. who cares really.. there won't be any more "Mazda rotaries" after this year.

People don't seem to understand the simplicity of the design. The combonation of the operation of THREE cylinders into ONE chamber. It's brillant, really. But it does have it's downfalls, mainly sealing and efficiency. I thank the person who posted the vid and ask why people have to write such negativity to a simple video such as this.

@maddogmatt44 Generally that's just a matter of displacement with wankel rotaries. That's the case too with piston engines. When you see figures like "1.8L V6" it's an engine with 6 pistons each with 300mL of displacement. Rotaries generally have a very high output for their displacement compared to piston engines because of the way they're rated and the way wankels are designed to complete a full combustion during a single rotation, versus pistons which require two rotations for 1 combustion

you need to rev the piss out of them to get you,re power out of them.

@Fubikon can you invent an engine like this ? :P

@yellowmonkeyisme 4 stroke, one crank shaft turn produces 12 cycles or strokes, everytime the rotor turns once around, 4 strokes have occured. he dosent explain this here.
