New engine technology - lots of HP out of a small package

[StevieC]

This was quite interesting...

160 HP, 25K RPM Redline. Only 35lbs​

Around 8 minutes in is where they explain it with full working animations...

Durability has always been the tallest hurdle. I remember when euros were making 1,000 hp out of a 4-cylinder race engine back in the late 1970's/early 1980's.

First thought...go kart!

I don't see any kind of cooling system. I wonder how they keep the engine cool enough to prevent seizure from heat expansion.

He stated it’s air cooled, and that nothing internally touches except the bearings and alignment gears.

Formula one make insane horspower, batteries, turbos, etc, but at $400 million per car anything is possible!!

This engine will save us when we run out of lithium.

I think there will be a seal issue like the Mazda rotary. Ed

Initially impressive, I'd rather have the 160 HP at a 5K rpm redline, or even lower.

 

[UncleDave]

Only works well turning a stator to make electricity.

It'd work well in a Volt type configuration as a hybrid.

Otherwise you have to spend ridiculous money and weight on a really strong gearbox to reduce this down to a workable RPM.

Is there a future for this stuff now? I mean, with EVs being mandated in many countries, there seems to be no room for any new engine requiring fossil fuels.

 

[wag123]

The impression I get is that this engine is being developed for the aviation industry.

 

[AZjeff]

That and some sort of CVT on a motorcycle? Would like to hear it running. Maybe.

They have a working prototype and they are starting initially with Aerospace but said it could be adapted for standard gasoline and other applications. The whole video of all them talking about the engine is about 30 minutes of the total video length.

As for sealing like Apex Seals they mention that in the video. It's not using any seals but extremely tight clearances so while there is some blowby it's so minuscule the engine can even operate on extremely combustible hydrogen safely.

It's a great concept that looks like it holds promise and will be interesting to watch.

With such tight tolerances, I would think that heat expansion could be a problem.

Maybe we can get them on here to ask questions similar to Pennzoil.

Good to see you back posting again Stevie.

Ford too (though not QUITE that level) with the RS200 Cosworth.

I wonder if

I wonder if thermal efficiency (correct term?) is so high that air cooling is all that's needed?
