It would be a hell of a sight!
I was looking at radial engines in the london science museam last weekend, there were some inventive minds around in the early days!
Was particuarly taken with the "gnome", a small early radial where the cylinders rotate around a fixed crankshaft.
The cylinders fill through the crankcase via 'flapper' valves in the pistons, exhuast gasses leaving through a single poppet valve on top
of the cyl head - straight to atmosphere.
I suspect it wouldn't be very free revving and would totally suck in a car but it was extremely cool
I suppose a small radial might fit a modified locost engine bay with the crankshaft pointing up vertically. Not sure how you'd transmit the
power to anywhere where it could be of use, but I'm sure if you really wanted to do it...

Not necessarily
Can you imagine trying to balance a whole rotating assembly. Another thing is they don't have much in the way of throttle control, run lowish
compression etc.
I've seen a scratch built rotary and radial (amongst others) - superb to look at, but completely impractical for car use.

have seen a car with a radial engine, but it was a scratch built special from the 20's or 30's with an aircraft engine in it, did go about
70 tho!
not cheap engines i would of thought to get hold of

NOISE how would you pass the noise emmissions .
Scot's do it better in Kilts.

Isn't a rotary engine another name for the wankel engine, as used in mazda's? I was talking about a radial engine, eg cylinders radiating
from centre, where all the cyylinders rotate around a fixed crank.
A rotating radial??

no radial is rotating crank and rotary is rotating cylinders, wankel is just wankel and is commonly known as a rotary engine but if you want to call
it a rotary engine call it a wankel rotary engine then your correct
