What have y'all heard about the FreeValve system? I know there's only one production car using the tech, but it's China-exclusive. Is there a possibility we'll see this in other vehicles in the near future?

But will it blow apex seals?
It's relatively new but within 10 years it will be in almost all cars. Just like electric steering appeared out of nowhere and are everywhere now.
In 20 years engines are going to be insane. Pneumatic valves, variable compression, jet ignition, variable geometry turbos, fuck me :)

>variable geometry turbos
I think assisted turbos will be the future. Volvo has their compressed air system going on production diesels and a bunch of companies are exploring electric assists. Shits going to be seriously cash. Mazda is also working on laser ignition although I haven't heard anything out of them on it in awhile so who knows how well it's going.
I thought Koenigsegg was toying with this?

Emissions will clamp even harder.
>>16873312
We will be mostly electric by then

Electric cars are a meme. We'll see more serial hybrids with more and more efficient engines.
>>16873341
Yeah, assisted turbos will definitely come along as well. I expect Mercedes and Renault to be the first to use them in road cars. I expect TJI will be the last real significant ignition system before someone finally wrangles HCCI.
>>16873346
They developed the tech and own the company. They showed it off years ago when it was still just a project within Koenigsegg.

Electric cars will never take over, not in the Americas or anywhere else with regular cold weather and long distances between everything.

I'm not sure HCCI will ever totally replace spark based ignition. I know Mazda is going to have a limited HCCI capacity in their Skyactiv 2 cars but it only kicks in during constant speed cruising at lower RPMs. Assisted turbos are actually one way you could have a pure HCCI engine but that's way down the line.

With everything that's on the horizon for ICEs that isn't a problem. F1 engines have already reached 50% thermal efficiency so it's only a matter of time before road cars get to and surpass that mark.

Free valves techonology isnt anything new, it's just a bunch of the older feautures implented by FIAT and BMW decades ago. Christian Von Koenigsegg was just smart to make use of them.
>>16873312
we already have all that.
all that is just useless shit to pad Emissions bullshit.
I'm personally very excited for it, based on the torque/power & efficiency improvements it's promising. Hopefully once the technology started to appear in more new cars there'd potentially be tuning companies that'd make kits to fit older engines, in cars popular in the tuning/modidifying scene, given the power/low rpm driveability gains it could yield. There'd be some sufficient expenses in the conversion to a camless head though (all the mechanical parts, wiring, connecting it to a compatible ECU/control system and getting the car retuned to suit) so in reality I don't know if there'd be a big enough market for it.
On that note, it's been developed/prototyped/retrofitted by FreeValve in a SAAB over the last few years. An interesting article http://jalopnik.com/what-its-like-to-ride-in-a-car-with-the-camless-engine-1529865968
