Concept power units from 2030

H900 seems to be speaking euphemistically while TC and gg are speaking more accurately. You can't detach piston speed from piston acceleration as H900 is holding to, but since the compression and tension forces experience by the piston & rod are described by f=ma then it's more accurate or at least more efficient to speak of a itself and not the separate components that a is derived from (stoke & speed). And as wuzak just posted, a being non-linear makes it the dominant component, beyond being a more useful derivative.

I’ve seen GG try to tell an Ilmor combustion engineer he was wrong about modern F1 PU’s by showing graphs from the early 90s elsewhere. They’re just stubborn.

Your inability to recognise the actual level of understanding demonstrated by that particular (AVL not Ilmor) "combustion engineer" clearly demonstrates your own level of understanding.

I reviewed the thread to which you refer after you posted a similar comment in this forum and had to shake my head at many instances of miscomprehension and confusion displayed by the "expert" you mention. (Do you still believe he has personal experience of an ICE with peak TE occuring at stoichiometry?) His multiple "appeals to authority" (along with your own) contrast with the actual evidence (eg graphs of any vintage) presented in that thread - i.e. ZERO!

He was at AVL then and has been at Ilmor for the last 5 year, so yes, I do.

And what about white hydrogen?
If it can simply be extracted from the ground, wouldn’t that require less energy than producing hydrogen?

Well, a quick peek at wikipedia shows "most of this cannot be extracted economically".

Which demonstrates how costly hydrolysis is. Moreover, you have to reinvent the wheel for transport, static storage, transfer, in-car storage... plus, cylindrical Type-IV storage containers would be preferred, so there's in-car packaging challenges. It's a big f'n mess that offers myriad reasons to stick with liquid fuel.

You "do" what? Believe in an ICE with peak TE occurring at stoichiometry? That would be a very telling.

Humanity should focus on solar-power and electrolysis for hydrogen generation.
