So who's going to be first .....

i like that, however considering you would need to completely redesign the mini head and over the last 2 years we've just got billet ali i think its gonna be a while

At last, mappable valves!

In the 13's at last!.. Just

Interesting watch

That is fantastic. You could get some amazing camshaft profiles that aren't currently possible due to the amount of jerk created. I especially like the concept of storing air during engine braking and using it to drive the engine at a later time.

Nice idea, I like the storing air idea too.

What a great idea..

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

We discussed this at college years ago, some f1 team made an engine work but who it was for love I can not remember its a cracking idea but problem.

word HYBIRD & ELECTRIC come into play...

also interesting is this.... as it will go on the mini block.

Nice

That's awesome.

BHP sells engines, but Torque wins races!

Clever shit!

Even with a hybrid cars this tech can be used on the engines used to charge the batteries.

Come on Matty I'm sure you can cobble summat together

the valve concept is great and will become common place in a few years if it passes
( extensive! trials ) for the everday car

but if you want an economy engine get an 850 mini.......lol

Wowzers !!

That's quite interesting. F1 cars still use cams as it's in the regs.

I alwaus liked the rotary valve idea. But they've never really been developed. I think they reached a dead end with sealing them.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

We were working with hydraulically actuated valves 20 years ago at Lotus! Apart from a single cylinder test engine, they had an Excel running around with them fitted.

You can, quite literally, get the valve to follow the piston down the bore and visa versa, maximising volumetric efficiency.

Also you can, in theory, do away with any butterflies in the throttle bodies and 'throttle' the engine by varying the valve lift.

The biggest issue was the hydraulic valving. Moving fluid around that fast generated a lot of heat. And, of course, you need to run a hydraulic pump from the engine to run the valves. Despite this, the net gain was quite impressive.

Given air is more compressible than hydraulic oil, I'd suggest this pneumatic system will be less accurate than the hydraulic one. However, it looks far more likely to become suitable for production.

im sure nickG has aready done this!!

I had a copy of an ancient car mechanics magazine from the '70s that had an article on a cam-less engine. I will also say the Koenigsegg series on the Drive channel is brilliant, Christian seems a really smart but down to earth guy.
