Its been awhile since I've checked the inlines for cylinder numbering, the radials I do know.
This is about how it looks like all those engines are installed backwards in the aircraft. Most all automotive engines and even industrial engines are numbered from front to rear. All the aircraft engines the number 1 cylinder is in the rear. Why? Because the power take off end is the front. The power take off end is always at the rear of any recip engine. So aircraft engines except for pusher installations are installed in reverse.

Just an example that there isn't a standard way of numbering cylinders, as others have also pointed out.I'm talking Radial's and Inlines, not opposed small plane stuff. The correct numbering is what the "Old guys" did in the day. Front is not the power take off end.

The convention of numbering cylinders on an engine (and thus, "front to back") is typically determined by where the crankshaft connects to the camshaft (via gears or chain drive) regardless of how it's mounted.
If its not for ease of the mechanics, then why number them at all? No-one but the mechanics really care where cylinder #1 is.Sorry to disapoint, but there is a logical way to number the cylinders, not that all manufactures follow the simple logic.
Some one mentioned corvair engines, they number it logically as are all the chevrolet engines I know of at least up to the end of the true SBC I have not done anything with LS engines so I can't comment.
Cam drive has nothing to do with it, there are cam drives at the flywheel end on some engines. And multi row radials have various positions for cam drive depending on the engine.
The mention of ford v engine numbering system, no logic involved with that, just what I would expect with them. Oh and I do have a ford product so !!!
I think some of the more non logical numbering systems were for ease of mechanics to learn, and nothing else, and would be why no convention with some. So now a simple question what is the logical way to number the average rear wheel drive V8 engines cylinders?
The first aircraft engine was the electric motor in the dirigible "La France" - built in France, funnily enough - of 1884.The first aircraft engine was built in the USA.
How were the cylinders numbered on the electric motor? Wiki isn't a help.The first aircraft engine was the electric motor in the dirigible "La France" - built in France, funnily enough - of 1884.
