The real question is: Why on earth would you WANT a conventional valve spring? Valve springs are extraneous mass in the system and subject to resonance and lead to valve float.
The point of the this engine excercise is to get rid of the camshaft and to enable infinately variable valve timing and the HP that can come with it. Ducati Desmodromic valvetrain is a great example of an purley mechanical valve train that eliminated conventional valve springs. Desmo has it's own issues of adjustment and complexity but it was a solution to the limitations of conventional springs and metalurgy of the early 1900's. https://www.youtube.com/watch?v=ocfIYUc5bpU |
