New engine can double fuel efficiency of cars

Whoa.. I hope this is one design that makes it to production. The only problem is that everytime something sounds too good to be true it usually is.

I'm very leery of any such claims. After all, it seems to be every couple of weeks that we're promised "something big around the corner" they always turn out to be vaporware.

Aren't modern combustion engines incredibly efficient as it is?

Combustion Engines are only about 30% efficient. 70% of all gasoline never gets converted into energy.

Most engines that we have(even the human body) aren't very efficient. But this 30% provides more than an alternate fuel source(electricity) at a higher efficiency rate.

some of the 70% becomes waste heat.

Wrong.

100% (essentially) is converted into energy. Just that only about 30-35% is used for propulsion. The rest is largely lost as heat (either through the cooling system or out the exhaust) with a tiny bit lost to friction.

Just because we aren't using the energy doesn't mean it's not being generated.

Very skeptical, but I welcome all new Internal Combustion Engine technology with open arms.

The very design itself is fundamentally flawed, though. Unless you can figure out a way to turn the waste heat generated into usable energy.

Ceramic engine parts, novel alloys, advances in lubrication technology and perhaps most importantly, infinitely variable valve timing will see the greatest increases in fuel economy in the years to come, IMO.

But like I said.. they've got my attention. Show me a reliable production engine my ears will perk up and my eyes will widen.

Until then, meh.

Thanks for the gut check Zenmervolt. That makes a lot more sense. When I read 30% that just didn't compute.

I don't see how exploding stuff can not lose a ton of energy to heat. Now use that heat to boil water to make water vapor expand via a steam engine and now we're talking.

Well that was my point. That 70% does not make it to the wheels, which makes it inefficient. I should have said 70% never gets converted into horsepower.

The question's been answered, but this misconception comes from people misunderstanding/mishearing the fact that modern IC engines have very good combustion compared with older ones

wheres jpeyton with his tinfoil hat to tell us that the auto companies are in bed with big oil and they dont want this thing brought to market?

As much as I would like to agree, I suggest keeping the amount of flamebait to a minimum.

They need to come up with materials that allow them to lighten vehicles while still meeting safety standards, too. And make exemptions on emissions for very high mpg vehicles... that should allow them to reproduce the results of the carbed Civic from the 80s that got ~50mpg, right?

Way to miss the point Mr. "I just took high school physics"!

 

[Rogeee]

15% to 20% efficiancy not 30%
The rest is either expelled out the exhaust as heat and high speed gasses,through the cooling system and through internal friction.
Remember that internal combustion engines use the expanding gasses from igniting hydrocarbons, they do not use the heat that is generated.

We already have the bolded feature in many engine designs AFAIK.

hahaha, he got you there! I'm pretty sure they realized that the energy is not, not produced.

Ah, but it is the resulting heat that is the cause of the useful pressure.
