Actual Rotary Displacement Request

Mazda conveniently choose to not rate the whole engine, if you or others can't get that then you need to move onto another area of interest I suggest, one you can understand

The Wankel Rotary is a 1080deg cycle, nothing more nothing less!

You btw f*** your own argument cause a 4 stoke is NOT rated after only 360 degrees! cause it HAS NOT COMPLETED ITS CYCLE OF OPERATION! it is rated ONLY AFTER 720 degree's (suck sqeeze bang blow) it only SUCKS once in 720 degree's! and ALL piston faces are counted to rate the displacement of the whole engine! not 1/3rd of them, or 2/3rd's of them! but ALL OF THEM!......... The irony is only in the rotary world where people want to only count 1/3rd of the combustion faces and rate it as a 2 stroke engine, but its NOT! its a wankel and thus they only want to count one face (which misses out 2/3rds of the rest of the engine). if only you could do this on a BDC built half bridge!!!! then when it drops an apex seal on each rotor he can then tell you its only a 2 stroke engine like people in this thread and the other 2 apex seals and four combustion faces are not required LOL!!!!!!!!!!!

Wow.... you are so off base its amusing.

ALL engines, 2 stroke, 4 stroke, rotary... are using only one rotation of the crank shaft to measure displacement.

If you use your logic, then the 6.0 liter ls2 engine would really be a 3 liter 2 stroke engine if you built a custom head for it and ignited fuel every revolution? ... I am sorry, but you are wrong. The bore and stroke never changed therefore, your logic is home to a MAJOR fallacy.

Wow.. you are arguing that somehow the method of measuring displacement has anything to do with which apex seals are required. To measure the displacement of a rotary engine, you would total the amount of volume displaced by one face of each rotor and add it up.

Just like in a piston engine, you would take the displaced volume of EACH cylinder (notice how 4 stroke or 2 stroke doesn't matter) and add them together.

Displacement calculation DOES NOT take into account how many revolutions it takes to actually fire each piston or rotor face. I have a lot of respect for you rice racing, but you are very far off base here. Displacement caluculations are simple:

How much volume is displaced by the engine (regardless of type) in 1 rpm of the crankshaft/eshaft IS your displacement. Its fact, non-arguable.
You can do displacement calculations without the heads on. it doesn't matter if it is 2 or 4 stroke. Hence why they do all 2 and 4 stroke piston engine calculations like so: stroke x bore x # of pistons = displacement. which would be the EXACT same as: displacement of each piston added together x 1 rpm. The 1 rpm factor must remain the same between all engines to have an effective and consistent method of calculating displacement.
