Rotary Engine

This animation provides a basic understanding of how the Rotary Engine is put together and how it works. It was created with 3ds max, Cinema 4D and After Effects.

Music from this animation is from the Ford piston engine animation found here:

Damn those apex seals

This is wankel engine not rotary....

[doktorbimmer]

@gorrammit I just confused myself trying to explain it 3 power strokes per rotor rotation not the eccentric shaft there is 1 power stroke per eccentric shaft rotation.

[gorrammit]

@doktorbimmer well since it takes 3 cranks to complete a full rotor rotation (which means 3 combustions) that makes 1 combustion per crank revolution...like a 2 stroke engine. I'm thinking in terms of power "stroke" per crank rotation. so the power to weight's almost the same, but the wankel's cleaner since it includes all 4 cycles.

Anywho, thank's for your help, maybe I'll upload a vid of my model when I'm done

@rittboy8u a wankel engine is a type of rotary, the term rotary is a broad definition of engines

@maguna75 to bad its originated form Germany :P

[gorrammit]

@doktorbimmer it's actually more like a 2-stroke piston engine (every full turn of the crankshaft equals 1 combustion)

[maguna75]

It is a smart animation! I am proud as a Japanese.

Thank you.

[doktorbimmer]

@gorrammit no problem, its a little hard to figure it out if your used to a 4 stroke piston engine where one turn of the crankshaft equals one up-down cycle of the pistons and two rotations equal one combustion cycle, but if you watch this vid carefully you can see the relationship between one turn of the eccentric shaft, one rotation of the rotor and the number of combustion cycles are not even like the piston engine.

@doktorbimmer Thanks for the reply.

It's weird, though, as each distributor has spark plugs that look to fire 90 degrees apart (with 270 degrees doing nothing) and those plugs are wired to different chambers (which are 180 degree apart).

I won't be building the distributors exactly like the real one, but i just found it odd.

Thanks
