Free valve, camshaftless engine technology!

Extremely interesting vid! Imagine one coupled with VGT

Yes I saw that ... very interesting technology ... and it's working ...

Most likely be seen on commercial diesels long before domestic!

Superb! Briliant!

like the fiat engines that have solenoids operating the valves?!

Have you got a link to them or anything I can read?

[campbellWS]

great video, very interesting ! i wonder if we will ever see an I5 with this installed?

[Billman]

yes the fiat multiair engines. But I think they run only intake and dont use throttle body because the valves do that job.

That link didn't work for me as it's got the m. for mobile in the link use http://www.youtube.com/watch?v=Bch5B23_pu0

Was unaware of the fiat !! But is it a fair comparison it still has a camshaft!

[Sleeper_Avant]

didnt watch video, didnt work

there has been camless technology for 5+ years now, hence why its dripping down to mainstream useage and universities are having students do projects on it!

search on Passionford, its been widely discussed there several times and lads have submitted their thesis files i belive

hope this helps?

also, did you know the "perfect engine" that was proved to a billion miles and patented, was bought by the 3 major manufaturers?
GM, Ford and ......someone else, weird thing, no cams, odd "piston" design and sperical bearings that used next to no fuel....E85 i belive or hydrogen, i forget or both?!

we only find out what they want you to find out lol

Thank you, I read about electrically operated valve trains a few years back but had no info to back it up! IIRC it was a British car manufacturer, think it was lotus! But for commercial/logistics I think this is a great idea.

[Sleeper_Avant]

its a cracking idea, but........... think how long the solenoids will last with the available technology, they just cannot warranty 100,000mile+ items, hence why motorsport has been developing and using them for some years now, little use etc

not forgetting the whole point of the twin air was to reduce friction/drag and it only weighs 85kg!

i found this, may be of some interest

if anyone wants further indepth conversations with propper engine developers of the camless technology using hydraulic operated valves (i mean serious discussions, not idiotic questions) i can pass on a couple of telephone numbers

Haven't they been using that tech in F1 for years? Sure the old F1 Renault turbo motors had hydro pneumatic valve actuation.
