Low cost gas engine doubles fuel economy - U.S. Politics Online: A Political Discussion Forum

This is brilliant, exciting stuff!! I expect more and more innovation over the next few years. Combine this with Solar, Wind, Nuclear, Clean Coal etc..and it won't be long before we are truly energy independent.

Quote:

Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.he current prototype engine, the X4v2, is what Revetec calls a “controlled combustion engine.” The meat of the engine comprises two counter rotating multilobate cams, which are acted upon by two pairs of diametrically opposed pistons which are rigidly interlinked by connecting rods.

If that sounds like complete gibberish to you, you’re not alone. Which is why I included an animation of the process to the left. A more simplified animation of the general motion of an engine of this sort is also included below.

Mr. Howell-Smith said that “if [the engine] uses 50% less fuel given that it has the same top end as a conventional engine, emissions would be reduced by 50% if the bottom end was utilized.”

Very cool

We need more stuff like this.

THis is very cool.
Hmmm - I suspect the SUV ego-maniacs will even further the behemoth size and enlarge the vehicle instead of lower the fuel consumption.

Why did I not think of this?

hummm how much for one engine etc.? well look, remember folks that order for any of the is to be truly worthy regarding dollars and sesne, the price of gas like it or not has to stay north of like $3.50......which I don't think will be a problem for quite a while.

Well, if true, can someone please explain how such a marvel came to be without massive federal spending? Could it be that the private sector, driven by greedy market forces innovates better than bloated federal ATM dependent researchers?

Great!! American auto makers with their huge quarterly losses need to get on board fast.

I think they only have one engine.
And they've been pushing this design for years, the article says they've been pushing the DoD to use it for an airplane since 2001.

And you can have a car with gas over $4/gal, ask any European, they've been doing it for decades.
