Well why not... it’s a matter of computerized solenoid control of the valves. Once that is done, no mechanical linkage to open the valves is needed, and no throttle or throttle body is needed. Why wasn’t this seen decades ago — was there a problem with engineering actuators that were robust enough or economical enough? With what-ifs, one could even envision vacuum tube technology driving the valves with an analog control system, meaning this could have been done in the early 20th century. So why not then, why now?

[Herosmith]

Very cool. I wonder how long the actuators can endure that hostile environment?

[Jeff Chandler]

I suppose it could have short push rods to isolate the actuators from the intense heat.

[sten]

Nah. I prefer the scalable design by LiquidPiston

[factoryrat]

This was tried in the past. The issue was mainly CPU horsepower, and external hydraulic pumps for the valve actuators.

With the advent of direct gas injection, high pressure rail diesel injector design, and stupid fast microcontrollers, this would be very feasible technology.

[Rockingham]

The automotive business is famously cautious, even stodgy, when it comes to engine innovations. The immense cost and risk involved require years of testing and prototyping and tight control over budgets and pricing.

[LibWhacker]

All that sounds awesome, but how does that actually work?

Sounds awesome??? Without cams it's going to sound like a squeaky rat with his nads caught in a vice, right? No thanks, give me my big cams (which have the side benefit of driving libs mad).

I though GP cars have had pneumatic valves for some time now, just control the timing by computer.

As long as the electrical power is good and you do not get hit by EMP, all is well!

And let's not forget the Massive Yet Tiny ('MYT' (mighty)) engine. The link leads to a picture which leads to the animation.

Gimme a chopped ‘34 Ford coupe, full-fendered, with a nice Flathead with Edlebrock heads and Tri-cards.

Mmmm, last 1,500 horsepower land vehicle engine I worked on was the dual-spool gas turbine for the M1A1 Abrahms tank.

Didn't quite have the same roar, though, as the nearly 5,000 shaft horsepower engines for the Chinooks.

I would prefer their car, the Koenigsegg One:1

Incredible thing. 273 mph top end.

You need to see the “Hitler discovers they’ve put a Wankel engine in his car” video.

[mewzilla]

Is this the one...

I'd never be on board...give me a max-lift cam and a set of big tube headers....music to my ears ;-P

Ah, LTGM, thank you for taking the effort to make live links. It's not that difficult, is it? It only takes a few extra seconds and dozens of Freepers will thank you. (If you have a simple post with now HTML, it will automatically make your link live.)

Those who don't know how, please go here: http://www.freerepublic.com/focus/f-chat/2827523/posts?page=4

Then scroll down to

How to create a link:

Print it out and keep it handy. I know it's not the most intuitive process, but that's how it is.

The 'sandbox' has all the secrets of making a helpful post.

The other basic skill everyone should know is how to post an image.

It's in the sandbox.

There is a lot more there than you probably need.

Thanks!

Rotary engine video. Mazda used this tech in their RX vehicles.
