Really cool valve technology!

[downforce22]

Cool for sure mostly because of the simlpicity. Wonder why people have been researching variable valve timing when something like this would make that a snap.

Definately will be revolutionary when it is implemented. What compresses the air, assuming you are cruising the air supply tank would run out if you didn't have engine braking to compress the air. A pump run off the engine? simple enough and it would definately have less losses than a chain or belt drive cam and valvetrain.

Many guys in the offroad world convert there A/C pumps to air pumps to fill up on board air tanks. So I think your on point there.

A version of this has been used on F1 engines for years now. It is an awesome technology though.

exactly what i was thinking when i first saw this

[King Mufasa]

The future is electricity and hydrogen, accompanied with technology like this.

Theory is wonderful.

I shaved my head once, and talked with a Sveedish akksent.

Practice makes motors.

'Memeber a buncha years back when F1 cars sometimes needed an air recharge
for their valves, sitting on the grid?

As with everything, the devil is in the details. The details, so far,
have stuck us with camshafts, and things like pneumatix and electomagnets
are having troubles with things like heat, pressure and time.

Maybe someday, maybe soon, but not wetting self yet.

i could imagine while in steady state cruise you could do a version of displacement on demand and turn one cylinder into an air pump (turn off fuel injector)to resupply the compressed air tank.

on the lines of valvetrain systems anybody seen the Fiat Multi-air system ,pretty darn clever and more adjustable and reliable than BMW's Valvetronic i would think. soon to be implemented on Chrysler engines . throttleless engines are coming and the only way to meet the new EPA mileage standards i think,reducing throttling losses are the next big step.

still the koenigsegg system would be the ultimate if proven reliable ,any cam profiles you want and adjust on the fly,crazy cool

that system is incredible. i think i saw someone above say F1 has used a version, which makes me wonder how/why this hasnt been mass produced yet...

anyway this kind of control is ridiculous and could/should be used in future motors. i got real excited when he started alluding to a turboless... turbo application.
great post

Very interesting indeed, but i couldn't help but get distracted by your signature lol
