    i don't think this is whats in the fit
    i don't think its in production yet

    i thought there were other constant variable systems that just BMW
    didn't lambo or ferrari have a continually variable valve system?

    Ferrari's variable valve system is a result of the valves being bent, loose and out of lash every 10 miles.

    Wowzor.
    With all that added complexity to the head, I would think it'd be a lot simpler to make the valves actuated by electronic solenoids controlled by the ECU. :shrug:
    WTF do I know.

    i dunno if an electronic solonoid can put out 8K actuations per minute

    Aura (Makers of the speakers and AuraGen alternators) makes a solid state valve head. (Well.. solid to the solenoids)

    But when you think of it, it's a speaker. 8,000 hz ? Why not ?

    Injectors can pulse at those RPM's. Just scale it up a bit.

    but how heavy is that setup going to be compared to a camshaft and rockers

    The A-VTEC probly won't add much over regular VTEC, but a solenoid activated system would be WAY lighter- no cams, rockers, cam pulleys, timing belt, plus all the material in the head used to support the cams. Come on Honda, DOOOO IT!

    I meant that it wouldn't add much WEIGHT. The performance/economy gains would obviously be drastically improved.

    They can make an acutator to do that, but to get them that fast with that much force against a spring would require alot of power. More electrical power would require a larger alternator. Then there is the reliability part, probably need bigger coils, the solenoids will get very large. Honda probably wants a simple, lightweight and reliable design.
