Wow, sweet sound on straight exhaust pipes!
-
How about that flywheel action as well. I wonder why it's so quiet?
Great video. Thanks

Maybe it's a combination of things - probably only doing about 400 RPM, with a big rotating mass and the natural 6-cyl balance? And those big pipes. Wouldn't surprise me if the compression is pretty low - a "gentle" combustion process?
There was a chap running an old engine at a show I went to a while back - a horizontal single of some kind circa 1915-ish - one of those things with a skinny flywheel but about a metre in diameter. It was very close to silent. Most impressive. I think maybe there's a hell of a spark from some of those old magnetos, too?
I guess it's a bit heretical to post about a petrol-engined machine here
And here is its father . . .

When it comes to diesel sounds, IMHO you just can't beat a Ruston 9H: https://www.youtube.com/watch?v=rPfoHbgcK2g
Pure industrial music.

Marvelous. The monster flywheels and low rpm of the Ruston singles is awesome.

Yes, those big Ruston horizontal singles are the princes of the diesel world. I guess with the long stroke and all that metal there is such a gentle combustion and flame front . . . . the cam-follower makes more noise than the cylinder. She's a beauty
