Amazing piston less engine. Omega.

This is pretty out there, 300hp too. Looks like nothing you've ever seen.

New engines appear all the time, but then you never hear about them again. They aren't fuel efficient, economic, practical, or reliable. I'm not holding my breath.
Seems this has the same problems that I have seen others suffer. Combustion sealing inefficiency? Combustion sealing wear? Combustion sealing cooling and lubrication? Combustion sealing tolerance and manufacturing cost? Lubrication in combustion or air/oil labyrinth seal cost and reliability? High RPM noise? High RPM reliability? High temperature reliability? High temperature material cost?
I am skeptical.

Rotary engine. Just a different design. New article, I'm sure I've read about this one a few years ago already.

"The Omega 1 has been described as highly efficient, although its efficiency level is not clearly defined."

"On the other hand, Astron Aerospace claims that Omega 1 has a high efficiency of 60% at that."

This looks like a twist on turbine engines, which are almost exclusively powerhouses for aircraft for a reason. Very high power-to-weight, but high maintenance and horrid on fuel at anything but sweet spot revs—something especially detrimental to consumer automotive. There's a reason they make it really easy to swap engines and find fuel for the Abrams—rebuilds take a while, and it's a thirsty girl.

My money is still on ICE hybrids and the eventual transition to hydrogen fuel cell—which is by all means full EV but with more dense power storage (for now) and a safer 'catastrophic failure' scenario. Looks like H-tanks and hydrolytic energy storage is promising enough at the grid level too, so I have a feeling it'll get a decent amount of adoption eventually.

Also, 25k revs? This thing is going to have the most obnoxious exhaust tone known to man. Christ.

300HP for what is it 150kg engine is damn good, and 60% efficiany if true is not bad for a smoker either. It's certainly a new design, and has no labrynth seals to worry about like the Wankel either. I'd love to see one for real or even a good look in a video.

Hydrogen is all but abandoned for cars, meaning less money for development. "Eventually" can mean a great many things.

Wake me when its actually in production.

 

[ShrimpBrime]

250 foot pounds of torque with a max of 25k rpm.

250 foot pounds? Did I convert that right? 340Nm?

That's why it's a concept motor. 60% effecient with 0 load. Lol

Is it? Ain't Japan still pouring a few billion yen each year?

Haha, the dumpster fire that is Toyota?

Yeah... so long as there isn't an Oil Crisis 2: Electric Boogaloo no one's interested in a car that has less trunk space and next to zero supporting infrastructure even in metropolitan areas. Automotive hydrogen's going to take upwards of a decade by my estimation and will probably be used mostly by cities replacing CNG fleets, but renewable (solar and wind mostly) energy storage? Not so far away.

I just wish that more people would keep in mind that big battery EVs with aluminum frames/shells are about as safe as a Ford Pinto in a collision. I see so many of those things get crunched and ignite themselves.

No I'm talking the entire country, aren't they supporting/subsidising research or something at some national level?

 

[thesmokingman]

No Im talking the entire country, aren't they support/subsidising research or something as some national level?

It's cuz Toyota runs the Kieretsu, they follow Toyota blindly.

One isolated nation with a very high population density (125 million people on an area smaller than California, and about 110 of those million live on one single island smaller than Oregon) pouring a few million euros into it every year (one billion yen is about 6.1 million €) don't mean much on a global scale. There hydrogen cars might make sense, just as hydrogen trucks makes sense for trucks in very specilized areas.

No I'm talking the entire country, aren't they supporting/subsidising research or something at some national level?

To add to the point above: Japan is incredibly isolated, and highly populous. They can develop entire industries that will never exist in other nations and it might work there but it might not work elsewhere. And to add to the population density thing: It's also incredibly mountainous, which means any flat surface will basically either have a high density of population or farms on it. Add to this a policy and culture of isolationism* and it all adds up to an ability to make very specilized stuff that might not make sense elsewhere.

*By this I mean they are very much part of the modern world but they are also very much not.

They would need a labyrinth seal of some sort somewhere. The way turbine engines work is air pressure is higher than oil pressure, and air creates a seal in a labyrinth to keep the oil in. Then the air is removed from the oil in the scavenging process.
Somewhere they are going to need bearings, oil, and a way to keep the oil separate from combustion. Otherwise, this thing will smoke like a 2-stroke and all environmental claims go out the window.
You can't use a traditional seal on a part that spins at 25k RPM.

That website is basically green energy clickbait and should be ignored.

 

[lilhasselhoffer]

So....about 20 seconds to look up the company itself...which was too much for the link:
H2 Engine

It's a hydrogen detonation engine...not something new. I sometimes forget how little people remember the past....or how many times we'll be sold on something too exotic to work in practice and too depressing to be anything but green guilt.

Here's a video, it doesn't work.
