Eu6 engines reduce the amount of Nox emitted. There are ways of

Smaller engines can use Nox traps but these don't work on lots of diesel
engines nor at high temperatures.

I dunno why - but they don't.

And this is the problem. Something which works under test conditions may
not work so well or at all in real world use.
