how many rotations of crankshaft does it take to fire all cylinders of v8 engine

I apologize, but I fail to see the relevance of sparkplugs to the matter under discussion...

A four stroke cycle Diesel still requires 720 degrees of crank rotati> Diesel engines don't need spark plugs.

I think the diesel is included in the "fire allcylin..." part of the subject. And there are four stroke cycle diesels as well as two stroke cycle diesels.

The Wankel does have cycles of induction, compression, power, and exhaust when doing it's thing - my guess is that's the reason a lot of folks are fooled into believing it's a 4 stroke engine. Consider me guilty!

Geez...get technical will you. Look at stroke definition 6a below (6 a : one of a series of propelling beats or movements against a resisting medium) or even definition 2 (2 : a single unbroken movement;). Why can't I properly say a Wankel is a 4 stroke engine using one of these definitions of stroke? For a piston engine stoke definition 9 seems best (9 : the movement in either direction of a mechanical part (as a piston) having a reciprocating motion; also : the distance of such movement)
