[Physorg] MSU researchers create a new engine prototype - Page 4

post #31 of 44
Its a shame the big oil companies are going to kill it off, just like they did every other engine breakthrough in the last century.

That is why 4 cylinder Turbo engines can get reasonable gas mileage and still put out incredible horse power.

Most of the potential energy in GAS is wasted through heat production in your engine. Heat=energy and in automobiles currently that heat is totally wasted except to heat your car in the winter, but still mostly wasted.
Ugh ... not quite. When you're cruising along the high way you aren't boosting and thus using minimal gas. When you are under acceleration, boost kicks in, you dump more fuel in to keep up the AFR, and thus make more power.

Turbo charging isn't exactly more efficient gas mileage wise, its just more compact for making power, and you don't need to be generating power all the time.

Sounds similar to an exhaust mounted turbocharger

Sounds like a laptop...

Just pay $300 and get it replaced...

Do you have any proof to that statement?

While I want to believe you, truly, and I don't really doubt the validity to it at all, because it's very plausible & possible.

Though, if you could outline some proof as to how they have been killing technology which would end the use of Oil/Gas, you may have stumbled upon something very huge here!

Have you seen under the hood of modern cars today? They are specifically designed to be hard to work on for the avg. gear head today so they can get more money from dealership shops.

Ugh ... pretty sure thats actually widely known. Though I'm heading out so I can't link to anything atm.

Why would they support technologies that would lessen the dependence on oil... Oil companies have huge amounts of money and are willing to spend it to ensure they keep making money.

No. They are specifically designed to be as lightweight and as compact as possible in order to conserve as much front hood space as possible for aerodynamics and wheelbase. The old motors were designed to be as open as possible because they blew up too often to not be.

Being a PITA to work on is a side effect, but anyone with a little know how can get around the structural issues easily enough.

Looks like just a modified rotary engine to me.
Much closer to an ugly love child of a diesel and a turbine, actually.

I need to see some more info on this one.
It's Wankel, not wenkel. I had one in my ancient snowmobile. But you're right, they're nothing like this.
