I'm not going to go into why a diesel doesn't need a throttle. Diesels are direct injection by definition and that has nothing to do with a throttle.

Ever wondered why diesel engines need NOx traps? Stratified injection would need an NOx trap as well because the cat would not be able to remove NOx with lean burn. No car in the USA has stratified direct injection, the only cars in this country that run throttleless are BMW N20, N52, N55, etc. engines, Nissan VQ37VHRs, and Fiats equipped with Multiair.
Lots of diesels are not direct injection and have a throttle body, this is also another place where it helps to know how engines are actually designed...
I'm just busting your chops, I'm not a jerk like some people on the internet.
Maybe you mean current US diesels and current US GDI motors. Maybe I didn't, either way, it's good to know we can communicate with each other respectfully.
