MarcJ. While your opinion/s is/are respected It just happens that I do not agree.
You don't agree with what?
MarcJ made several points and I agree with most of them. (Certainly all the technical ones.) Are you saying you disagree with all of them?
There is no point in simply stating that you disagree. When I disagree with something you say, I make the case for my opinion. I don't care if you still disagree - my aim is to present the alternatives so others here can weigh the arguments and form their own opinions.
You have read my opinion on TJI and the modified version that is used in F1. There is no way these engines can run the ultra lean mixture, the high compression ratio and the extreme peak pressures we know they are running - without a fast-burn, stratified charge system like TJI. There is no other concept that can do what TJI does.
KSPG are supplying steel pistons to a OEM for a V6 petrol engine. Now could that be Project One.
There's plenty of published papers on steel piston for gasoline engines published by Ferrari University di Modena. Saverio Barbieri.
Doesn't matter if your combustion of MiLD ultra lean low temperature combustion is in a reciprocating engine or rapid compression machine it's still low temperature below 2000 Kelvin at peak thermal efficiency.
So heat issues of stoichiometry not relevant here.
Ferrari said they used 3D printed steel pistons at Phillip Island in 2017.
