Camless engine

http://youtu.be/Bch5B23_pu0

An interesting overview of camless cylinder heads. I enjoyed, maybe old news to some.

Also, check out the stability on their new car, that's some good traction control.

I think the first one is the new "Have you seen the new Ken Block video?"

The second one's new to me though...holding straight under braking is just good brakes, suspension and alignment, but the way the traction control lets it do seemingly infinite full-throttle oversteer transitions is nuts

An engine with no cams you say? Like a 2-stroke?

And here I thought we were talking about twisted doritos....

Konigsegg is allegedly working on applying a solenoid system instead of cams, valves, valve springs, etc.....claimed it can yield more power and efficiency in a smaller lighter package.

WOW........... me likely!!!

I'm convinced that camless technology will usher in a new 'golden era' of the internal combustion engine. It will provide unlimited tuning potential for efficiency AND performance, torque AND horsepower, emissions AND speed.

isn't BMW already producing a camless engine that also does away with the throttlebody. It actually opens the valves in response to engine load, RPM, and throttle input

If it is not camless, it is at least extremely variable

I really hope this turns in to something, I really wanted to see that SAAB run on the dyno though

Right not camless but constantly variable lift, which acts as a throttle.

Amazing possibility that should have been backed up / integrated sooner if not for the hybrid distraction automakers have been all willy nilly with.

Hi Folks, A google alert on camless engines introduced me to u. Here (http://www.youtube.com/watch?v=Bch5B23_pu0) is the link to koenigsee's camless engine development. It is a pneumatic valve actuator engine and not solenoid controlled. Keeping the magnets in a solenoid alive at that hi temp will be undependable. To begin with getting rid of the cams would be too ambitious. Pneumatic valve actuators that replace the springs at the valve poppets like on F1 cars would itself be quite a stride in efficiency increase. Besides, the flexibility such a valve gear arrangement would provide to hybrid engines will be huge. Valve idling in gasoline hybrid engine, crucial in eliminating engine's drag during engine braking and offer the entire returning torque from the wheels at the crank-pulley for the alternator to harvest far greater electricity (or) Opening exhaust valves of air diesel hybrid engines during engine braking in-order to collect the compressed air expelled in the process. Whatall you do with this recouped compressed air is quite endless. To begin with it could supply the air for the pneumatic valve actuators, provide the compressed air requirement of the car's air conditioner and best of all return this air back to the cylinders during the torque challenged regions of the IC engine to provide thrust and do away with the gearbox.
Happy motoring!!

Consider the square cam opening though, the fact that it's not riding on a lobe, but pushed and held open is really important for efficiency/power of this over other designs. They've also apparently put quite a few miles on their test mule, so it's more than just a fancy 3d rendering and a few test samples.

On the Stability control: you could tell the driver on the second video was a bit more than decent, but still an impressive display none-the-less.

Are you guys not seeing the same video as me for the first link? It's a /drive video overview of the camless design they're working on.

Camless, not valve-less and 4 stroke. Should've been more specific.

2-strokes are hardly models of cleanliness, though they are really powerful.

Fiat Multi-Air is close.

Not, it's not. Multi-Air is just another evolution of VTEC, VANOS, etc. You are still constrained by a camshaft. The things you can do with all of the valves completely independent of one another is truly staggering.

More than anything, I'm just completely blown away by what these nuts are doing with (as of 2012) about 50 employees. I realize they're outsourcing some stuff, but holy E36 M3, that level of engineering and manufacturing quality is on a completely different plane from what the boutique manufacturers were doing even 5-10 years ago. Bonkers.

Trust me, work on camless engines has been going full speed before, during, and after Hybrids. They came, the promise was not fulfilled, and they left. Waiting for a different version, I suppose.

It's one thing to get a car to work on this kind of valvetrain.

It's more when you need it to start after sitting a week at -20, or customers get rather upset. Not that the problems can't be solved, but there are a lot of them that need to be solved.

In reply to accordionfolder:

Yes, traditional 2 stroke engine are not clean. That could however change with direct injection technology for both the fuel and the lubricant (http://www.youtube.com/watch?v=eu3NEPSBfUs) . These light and simple engines fire twice as fast as 4 stroke mills and could render 4 stroke camless engine development futile.

Say hello to yet another stunning engine development! A 2 stroke twin cylinder engine in opposed cylinder, opposed piston configuration with 2 connecting rods / bank!!

Ring-ta-ting-ting. 2-strokes to rule the world.

They should make a 2-stroke 911, 3.0 flat six, bunch of tuned pipes. Sort out who can drive, and who cant.

The Kohler 2T 6 cylinder CSR is the most badass car. Full stop.

me still likely....

Got it in 1----

I wondered why they didn't use solenoids too, controlled by transistors. That junk is crazy fast.
