- The use of a valve train consisting of camshaft, lifters, pushrods, rockers and heavy springs is really a fairly primitive way to open and close valves, and is certainly a performance limiter. It see

- The Knight sleeve valve engine certinly ran in lots of cars in it's day. And the engine in the Supermarine Sea Fury I believe was a radial sleeve valve engine. Plenty of rower there. -- Original Mess

- I saw a comment on the SAE site several years ago about a single cylinder lab motor used in a feasibility study that had solenoid controlled valves. Also a comment about one using hydraulic cylinders

- I think these guys have what you want. I emailed them a couple years ago, got very little answers (wasn't a viable customer at the time) I would like to get this kind of system into my eclipse. <http

- I looked over Sturman's website. If I take what they say there at face value it looks like they've pretty much solved the first order control and valve actuation problems even for pretty high rpm's.

- Working vehicles with solenoid valve actuation don't show me a lot. I can think of several dozen current and past land speed racers who would be perfectly capable of taking a modern car with a 4 cyl

- That's an interesting idea, sounds like the first steps in a mechanically controlled system... I think these guys at Sturman are using a computer and some hydraulics to perform this operation. Yeap,
