End of the CamShaft ?

That was extremely interesting, i've thought about that for a while as it does seem very restrictive that you generally have the 1 or at most 2 or 3 camshaft profiles which have to 'make do' over all rpm ranges.

I'd read a few years ago that someone had been experimenting with it but were having issues making it reliable over the hundreds of thousands of miles and many years you need it to work for but i'm sure that's something which can be resolved nowadays
 
Fascinating stuff. The reliability & cost of the system will inevitably be improved dramatically with development and funding.

The possibilities to reduce weight & size, and increase power & efficiency are immense!
 
This is why it is a shame Koenigsegg never bought Saab. They could have done some fantastic things to bring them back to the forefront.

Yea including overhauling the aesthetics too!

Concerning the camshaft I hope it lives better in reality and mass production than the Wankel Rotary engine did in it's various iterations. Least efficient engine ever ;) ?
 
Wow, very interesting.
30% Reduction in Fuel for a 30% increase in power. How about we keep the same fuel and make it 60% more power ;)
 
It is good to see some further thinking on the internal combustion engine.

Most modern cars are OHC which has been around donkeys years, in fact Fiat were starting to produce the Twin cam in the 50's. Since then the basics haven't changed very much.

My worry was all this pressure to produce electric cars would stump development on engines.

Glad to see my fears were wrong.

Electric won't suitable for years, on it's own at least. Hybrids with a conventional (highly efficient) engine and electric will probably be used to bridge the gap. I recall seeing a Top Gear with a supercar (I forget which) that used electric and a big ass petrol to augment performance (rather than efficinecy/greeness) electric = loads of torque, no lag + petrol = loads of power :D
 
I hope I dont sound too daft asking but with this technology am I correct in thinking no more cambelts? and also would you still need a head gasket?
