Since the displacement of piston engines is based on the volume  a piston
displaces in one stroke times the number of cylinders, I would say
the 13B rotary displacement is the volume of one rotor face on the
intake phase times six. Karibian


You are too late for the contest Hurant.

I am still waiting for all the votes to come in.

Paul Lamar ...No rotor no motor.

Actually "rotary-engine displacement" is when the wife throws  pillow and
blanket at you, saying "If you're going to spend all your time in  the
garage working on that damn motor, you can sleep out here too!"

Keith Wood

I vote for Keith Wood's answer.

George Lazik

I think Keith Wood wins the prize. We were all barking up the  wrong tree.

A cycle is when the piston goes through intake, compression,  ignition and
exhaust. Each rotor has three faces to go through the same  process. Karibian


OK if you guys are not going to vote I am going to decide who
did the best job of describing the displacement :)

At least vote for yourself :)

Paul Lamar ...No rotor no motor.

Karibian, Yes a cycle designation is going through intake,  compression,
power stroke, and exhaust.
A Wankel engine needs three shaft rotations to complete the four-cycle
operation for all three chamber.
A four-stroke RPE needs two crank shaft rotations to go through all  four
cycles of each of its cylinders. That is true for one, four, or for 24
cylinders.
A two stroke RPE always combines two strokes (power and exhaust, and
intake and compression) and needs only one crankshaft revolution to
complete its two strokes that include intake, compression, power, and
exhaust.

Now, how do we compare the four-stroke Wankel engine with the
Reciprocating Piston engine?

vote snips....

A two stroke RPE needs one rotation, a four stroke RPE needs two
rotations, and a Wankel engine also needs two rotations for two
chambers, just like the four-stroke RPE. Counting two chambers in the
Wankel allows a direct comparison with the four-stroke RPE, and  that was
the aim.

Paul,
Even though I am not from Chicago (does visiting count?) I have voted
for myself three times.  Has anyone taken notice?  Does that make me
a no account?

I've had four offers to join the Free Masons since my comments about
Kiwanis.  They want to cement our relationship by providing a
subsidized lifetime membership.  They say this is a concrete offer
and that they are good at building relation-ships.  But I'm not sure
I'm interested in reruns of the Love Boat.
John Dinkel

No and Yes :)
