Topic: Koenigsegg developing "valve actuators" to replace cam shaft

Results in 30% more power/torque/fuel economy and 50% less emissions. Sounds almost too good to be true.

I could see those gains IF they can get it to work reliably. That's basically removing half the parasitic drag from the engine. Surprised no one has tried this before, especially Porsche or Honda.

[LesterPiglet]

Very interesting. I wonder how motorcyles will develop if this proves viable.

[bwaller]

Interesting stuff.

Old Hat......MotoGP and F1 have used it for years...!! Nicky Haydens Honda 2007

Yeah, I saw guys trying this out on a 350 Chevy a few years back on youtube. Great idea but the technology wasn't there yet.

The tech is there alright but it's no where near cost effective for production use. It's the reason F1 engines can buzz to 18k+ rpm but it has a big price tag. Doesn't surprise me that Koenegsegg would take a swing at it because most/all their clients are billionaires who've got nothing better to spend their $ on.

With the last cars from Koenigsegg they've proven that they if any car company could have the technology to make this. Would be cool

BTW. Im from Sweden so I might be a little partic and right now im about 20 km from the factory

no one has yet made this idea work , all the major manufacturers have tried and so far all have failed .  f1 engines do not use this technology [ in fact the rules prohibit it ] they rev to 18 thousand by using pneumatic valve springs the same as the motogp bikes

You mean they havent succeded to produce a serial manifactured car ? Cause in the movie they state that they driven it during 2,5 years, 60 000 Km..

The Nissan 370z doesn't use an intake cam.  I'm not sure of the exact mechanism but it sounds similar to what is described here.  It's their VVEL system.

no i mean no one has made it work , they didnt tell you how many times it had failed in 2.5 years and 60,000 km . i believe the actuators have a very short life , it is definitely the future though all the major manufacturers are working on it . as well as the benefits stated in the video once perfected it will make engine manufacture alot cheaper as well .

the nissan 370 does use an inlet cam the vvel system uses a servo motor to alter the cam timing
