Koenigsegg seems like they're full of gimmicks now. The One:1 wasn't anything new if you really break down all the flashy angles Christian throws at you into less dramatic terms. Honestly I like Koenigsegg but at the same time I see through their bullshit. Nothing in those cars are revolutionary and even this has been done in formula one for decades now. there's literally no other way to get a motor to rev that high than to replace the spring with nitrogen chambers. Look into formula one valvetrains.

>>14202307

This. And the whole "freevalve" thing was done a long time ago, that video is pretty old.

Never heard another word about it. Where is it?

I even have the same engine, so if they would actually produce something I would have a use for it.

I get what you're saying but disagree. A lot of this stuff hasn't been seen in a road car. The One:1 was mainly cool because it was a 1:1 car that wasn't a shit box from the 80s with a turbocharged LS1 shoehorned into it.

>>14202324

Whats the problem?
>>14202337

I wonder if this will trickle down into diesels. Torque is king.

>>14202357
>wanting to make a reliable engine more unreliable
i dont know why people are so obsessed with over complicating engines

Pushrod, OHC and DOHC all have their applications and anything beyond that including VVTI or 2+ stage variable cam timing is not needed

Dont get me wrong, I love mechanical diesels, but I suppose I should've said Im curious how much more torque could be wrung out of diesels with this set up. Calm your tits, you're as bad as the poor kids up there.

>>14202378

>6 year old article
>even gm didnt bother
http://www.hotrod.com/how-to/engine/hrdp-1007-gms-variable-valve-timing-system-performance-test/

besides diesels are almost at the limit of what they can do

>>14202378

Large frame marine diesel engines can be found with hydraulic poppet valves replacing cam driven valves.

>>14202180
Not as good and simple as Multi-air will take another decade or two to implement in all vehicles - at that moment ICE's might not even exist anymore.

As said, Multiair sounds like a better idea, especially with a V engine and a single cam in the block's valley. Using a camshaft to generate a modifiable hydraulic signal that pushes the valve open sounds like a better idea then using electrohydraulics, at least in a passenger car configuration.

>>14202392
is it reliable?

Yeah nah their known for catastrophic failure from 40k km upwards

Absolutely it is reliable. However the systems are large, require PTO for hydraulic pumping and generate heat that must be cooled with auxiliary heat exchangers.

>>14202209
Multi air is hydraulic and uses a camshaft.
Because its hydraulic, valve lift is influenced by oil viscosity.
So if the oil is hot, or you put in a different grade the valve lift will change.

Eh.

I'll stick with my SBC and SBF engines.

That's nice and all, but pneumatic valve retrofit kits for mass market engines when?

>>14202180
what kind of effect would this essentially square cam profile have on the gas flow (incosistency, turbulence) in/out of cylinders as the valves open/close

>>14202984
Dont over think it pal.
You cant actually run square wave because of valve train limitations.

The benefit comes from variable duration and lift and moveable centre angle.
Plus the benefit of throttling the engine with the valves, not the throttle plate reduces pumping losses.

Its all fun until the electrics fuck up. Rather have mechanically driven valves over this..

>>14203017
You're thinking of electronics. Electrics never fuck up unless they burn a fuse in which case replace the fuse. But hey, your choice, enjoy readjusting your carburetor weekly and needing a miracle to start the engine in winter.

>>14203892

Give it 15 years; after they do the low displacement Tri-turbo engines, the Europeans will start using NOHC engines but with a hell of an upcharge (if German), and of course Honda and Toyota will start using the technology in new econoboxes.

But of course rhe technology exists, it's not like the technology is sold ONLY to the 1% of manufacturers to benefit at the expense of everyone else somehow.

>>14203865
The regera is the (non-series) hybrid that ever looked interesting, due to nogears.

Corny eggs will keep using ICE until it isn't the fastest thing they can make anymore, which might be a while but I wouldn't be surprised if the proportions are suddenly flipped next (ICE as more range extender than power).

>>14204779
No Chrysler does not. They could release the 5.0 Pentastar V8 that is listed in the patents. Hell, a smaller (ie shorter) head is already in production for the V6. Wouldn't be a stretch to make that design camless and solves the 2v problem. I don't see it happening any time soon, a Multiair PUG is more likely but you never know.

>tfw already worked in automotive R&D during bachelor studies

>>14204942
one might believe this if they only experienced one working environment.
in truth, delphi, denso, bosch would make the same progress in a year that cargine made in a decade

>>14204932
As some one who's worked in r&d on engines using multiair, 6 iterations a year is a pants on head retarded statement to throw out there.
With a constantly variable valve train can you imagine how long to takes to run sweeps for lift, duration and centre angle, boost and ignition timing?
Plus compression ratio changes and different octane testing?

We were testing 16 hours a day. I ran the engine 8 hours a day for 9 months before we had the combustion system change. And then engine grenaded (piston broke at the boss around the pin) and we had to wait like 6 weeks for the prototype head to be repaired, and rebuild a new bottom end with used parts.
