Scientists Claim Major Leap in Engine Design

Finally someone is investing into new technology, the current combustion engine has been around for more than 90 years without any significant changes.
 
That stuff is nothing that new.
Variable valve timing is a neat idea that was invented a while ago.
This is just another cycle in the evolution of the idea.
 
That AGAIN, I thinks its been some time now they are working on that

It will be SOME time before we actually get that in our everyday car methink
 
It would be such a drastical change that, of corse, it will take years to drive these everyday. Hybrids have been around for quite some time now, and I still don't see that much on the road. Not enough for me to quit thumb-up'ing the ones I see.

But then, at last, we will have a new type of engine. No more snapping timing chain. Hello computerized engines, your time has come, finally. Mechanic is a beautiful thing, but electrical and electronic is the way to control the physical movement, just like our old good body of ours!
 
anything is possible but nothing will change as long as there's profit to be made off combustion engines as we know them
 
The problem with some technologies like electric valve actuation is that it takes some serious electrical plumbing and if you loose the juice, the engine will just ceize and you will get epic engine braking.
 
^This concept is perfect for motorsport, but for a reliable daily, I think there are other way to enhance eco crafted cars
 
^ That would be great since about 75% of the total energy of the fuel burned goes into heat (heat into exhaust gases, heating the block, heat into the cooling fluid...) If we could get 1/3 of that heat you would double your fuel economy, and probably have lot more power.

this is not just toyota's vvti.. it's more than that...
problem is, until you tune it right, you're going to scrap quite a few engine heads..

there's gotta be SOME way to harness the heat created by the engine to access more power.. there just HAS to be.

I give you the BMW turbosteamer

http://www.autoblog.com/2005/12/09/bmw-turbosteamer-gets-hot-and-goes/

BMW’s announcement of the new technology is somewhat of a technological bombshell as it adds yet another form of hybrid automobile – a turbosteamer. The concept uses energy from the exhaust gasses of the traditional Internal Combustion Engine (ICE) to power a steam engine which also contributes power to the automobile – an overall 15 per cent improvement for the combined drive system.

you cant "create" energy
It goes against physics you cant output more energy than you input.

u can't put more energy than u input, oh yes, it just makes as much sense as 1-1=0
i think everyone knows that.
and i think he never meant that heat was created out of nothing.
engine takes the input energy which is gas/air mixture in this case and "creates" work and heat as output energy by detonating the compressed gas mixture.
so in a way, it does create.
so what the other dude meant was to somehow recirculate that heat energy "created" and make good use out of it.

it's just funny how some ppl assume that everyone is dumb as rock.
or was it a vocabulary lesson u wanted to give

im still not entirely sold on it yet. companies are going more and more with electrical motors,devices for some major components(prius having sensors at the steering wheel and an electrical motor at the rack and pinion with no steering column,some companies using drive by wire for the throttle). don't get me wrong its great when it works but imagine your on the 40 taking a slight turn at 100 and as you go to turn the computer says no and you plow into a wall, or driving through a school zone and just as a small child jumps out in the distance you go to slow down but the computer keeps up your speed or increases it.

it just seems like there isn't enough of a fail safe for safety. and seeing as a climate like what we have here doesn't do to well with some electrical systems there going to have to really make sure their wiring systems stay mint condition for a long time,and repairs are done properly.

Thats pretty much what i meant.. and it seems that BMW, as mentioned above, has started an idea on that concept, which is phenominal to the output of a vehicle.

for being that hot, you cant really assume you CAN'T use the heat to an advantage.. I never took physics or chemistry or any of that crap but it just seems common sense that you can use more of what you have.

the engine already is made to run.. its more of people needing to find a way to harness more of the power.
