**** what's with these ppl when you measure displacement in a piston engine you don't mesure the combined displacement of all the cylinders combined you measure the displacement of 1 single ******* cylinder.. holy **** lay off the rotary it's better just admit it..
you nave never, ever built a motor in you entire ******* life you stupid little ****, so shut the **** up
**** you again

If you follow his logic, then a CR250 (250cc two stroke dirt bike) should be re named
CR500/2*1.3L^5 or something like that.
The measurement of the volume of a cube is the same no matter the shape. Simple
geometry. H*W*L You make the appropriate adjustments for the shape (cylinder,triangle,
square) but in the end, you still end up with the total compressable volume.

For everyone who voted 1.3 liters, what is your reasoning? Mazda said so?
Does anyone here even know the formula for single chambver capacity on a rotary? For anyone who cares, here it is:
V = 3 x 1.73205 x REB
R = generating radius, the distance between the rotor centerline and the rotor apex
E = eccentricity, the offset between the eccentric shaft centerline and the rotor centerline
B = width of the trochoid chamber
For a 13B the measurements are R=105mm, E=15mm and B=80mm. This gives the familiar single chamber capacity of 654cc. Multiply by two rotors and you have 1308cc.
The argument really stems from the difference between capacity and displacement, or working displacement and how it should be measured.
Does anyone wish to discuss the subject intelligently?

Here's my email address Lannyrx7@excite.com Paypal me a dollar and I'll talk intelligent with ya. J/K I suck at math, besides that's just too much trouble.

Thank you for that. I didn't know how they measured it. I thought they used a
(Base*heigth/2)*Depth(rotor width) type math.
