Wankel engines provide a lot of power per pound of engine but at the price of not being that efficient. Nothing wrong with the technology (other than getting seals to work) it is just a technology without many applications. We live in a world where MPG is more important than HP per pound of engine.

“If it were strictly up to industry, there might be some hesitation – but in this case, it is not up to industry, but to government, which has mandated a sharp drop in emissions for vehicles by 2020.”

I read the article enthusiastically until the very last sentence. Then I got a bad feeling for some reason.

Looks like they improved the Wankel engine.

These miracle technology stories come out of Israel every once in a while. A few months ago it was a cure for cancer.

They DID save Intel's bacon a few years ago with a MUCH better processor design, so they're doing something right.

The problem with the Wankel was a lack of complete burn of the fuel and consequently, exhaust temperatures. An engineer did patent a fix for this by adopting an oval ejection port. This helped increase the burn time and reduced the exhaust temp.

My contacts tell me that Mazda has currently tabled the Wankel, but is investigating the patent. No word as to when or if they will adopt, bring back, etc.

Average power use of a car is not that great. A generator that can create a little more than average power use with a supercap or battery for acceleration could make for a very fun car to drive.

Found some sketchy info on the internet (thanks for giving the name, Aquarius).

It looks like it might be a free-piston internal combustion engine directly driving a voice-coil type electric generator. Output goes to power electric motor drive for shaft power to vehicle wheels.

This is not a new idea. At least 40 years old.

Head of Business Development looks kind of cute.

“If it were strictly up to industry, there might be some hesitation – but in this case, it is not up to industry, but to government,"

He's got that bass ackwards. If there is profit to be made, private industry would be the best vehicle to advance this technology.

Remember when the Wankel rotary engine was going to be the wave of the future? Is this another untried engine that will be a disappointment?

...

Orbital Engine, too.

Toyota is now getting 40% thermal efficiency from their gas engines in their hybrid systems.

Surely another technological breakthrough that can save the world and Israel will be condemned for harming Palestinian women and children.

Wrong. The Saudis want low oil. When oil is low then the capital investment in energy-saving projects (like the one in the article) is low. The Saudis only stop profiting off oil if there is a game-changing invention which reduces demand.

The inefficiency of power conversion is not in cams and valves, it is in heat. Most, like 80% of the wasted energy is heat, this engine has that loss.

It’s a hybrid that burns the liquid petroleum fuel in the engine to create electricity for a motor, instead of back at the coal-fired power plant.

That’s what I read. I could be wrong.

Yep and still subject to the laws of thermodynamics.

Carnot efficiency rules still apply, unless it operates at very high temps and pressures, it will be less than 50% efficient like all the other IC engines.

Exactly what I was thinking. The article says very little about the design, but in the picture from the article, the man appears to be holding an aluminum part.

Sorry fellas, you ain't gonna get there if you are using that as your engine constructing material.
