Are these internal combusion (IC) engine claims physically possible?

[member 656954]

TL;DR Summary

A persistent person on another platform keeps claiming what seem to be impossible outcomes for juiced up ICE. I think it's junk and he's a crank, but don't have the knowledge to challenge him.

For the most part, I ignore seeming cranks on other platforms, but the persistence - and insistence - of one who keeps claiming what looks to be physically impossible attributes of his ICE engine finally triggered my "Okay, I'll ask some experts."

His written posts are along the lines of this (crazy font is his):

"Here is a close look at our disruptive 𝔽𝕦𝕖𝕝 𝔸𝕘𝕟𝕠𝕤𝕥𝕚𝕔 ℤ𝕖𝕣𝕠 𝔼𝕞𝕚𝕤𝕤𝕚𝕠𝕟 - Ultra Efficient, Maximal Performance, Low heat/noise signature, Non-Polluting, Torque/Power Dense, Engine Technology including why it's better than electric/hybrid propulsion. Achieves >100mpg...including hydrogen"

And his supporting 'evidence' is the attached flyer.

What I think is fiction, includes:

• Non-polluting ICE - it is still burning fuel, so unless you capture 100% of the emissions (and presumably store them somewhere in the vehicle) you can't have perfect combustion.
• Constant maximum torque and efficiency at "all time/load, temperature and elevation". ICE has gears for a reason, and that's because it has to spin up/down, so this seems like straight up fantasy.
• Claims "negative carbon footprint with hydrogen". I'm ignoring the negative CO2 as hyperbole, but I understand that hydrogen ICE is not ideal because of low energy density but also, they are hard to keep tuned to minimize NOx.
• Says it has 'zero-emission' so why would you need a 'Quiet, low heat, smokeless exhaust'?
• Runs on any "liquid or gaseous fuel [natural gas at home!] incl. biofuels & hydrogen, even if olddirty/unprocessed like flare gas". Is that even possible? Don't you need specialized machining for different types of fuel - like, a diesel engine is different to a gasoline engine?

I'm not going to rebut this guy because that's unnecessary and won't change his mind, so I am just interested for myself as to whether this type of engine is even physically possible or practical in general use.

If you believe its too good to be true then its too good to be true. His claims aren't scientific or even match what we know of engine performance. No need to discuss this further.

His claims violate thermodynamics laws and sound too incredible to be believed.

That is the consensus here at PF.

Closing the thread as there's nothing more to say. We don't discuss crackpot ideas or perpetual motion or these kinds of incredible motor claims.
