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.
