Desmodromic Engine

[franzh]

Has there been any more work on the Desmodromic engine? The Ducati and the JAP bike engines proved it would work. I once saw a lab engine with the desmo valve setup and it was eerie how easy the engine turned over when there was no valve friction on the camshaft.

Franzh,

I am not sure that I see a big future for desmo; VVA and camless is where the future lies.

I agree about camless valve actuation, I have seen a few engines operate and are quite production capable. No throttle, docile idle, unreal power response (imagine swapping camshafts while driving!)
I read an article about the Desmo several years ago and was wondering about the state of the art. It was quite unique.
