Does that mean that we all move back to buying diesels again? :')

It will still be polluting, (NOx and carbon particles.)
So no advantage there.

The pollution created by an IC engine depends on the type of fuel in
use.


Unless you can stop the engine breathing air, high combustion
temperatures
will produce nox irrespective of fuel surely?


Mmm. You can do combustion without using air.

The classic is heating coal and metal oxide. What you get is pure CO2 and
metal.

Not using coal you don't.
Which is why coke is used.


Then you can burn the metal in air back to oxide and feed it back in


The NOx is produced mostly in ICE.

Burning the same fuel in say a boiler, produces far less NOx as the
temperatures are much lower.
Also virtually no carbon particles (in a modern boiler).
