I was reading up on dpf scr and egr and how these new engines can be made more efficient when i came across 100 hp mcrd engines made by mahindra . They use a catalyst converter same like your honda instead of dpf filter and scr to meet emissions standars.i can already see big names companies going this route by 2027 . The engines will get more fuel efficient trucks will get 500lb lighter. No more failed turbos. No def needed and no more limp modes. What do you guys think ?

I don't think it would be very reliable. When a single injector fails on a regular passenger vehicle, it plugs up the converter. That's from 1 injector going bad causing the engine to run a tad bit rich and makes a little soot. Now imagine a 450 HP diesel...
What happens when the converter is full? Will it regen? Will it need replaced? How many thousands of dollars will that cost? If it does regen to burn the soot out, it'll be no different than the disastrous 2008-2010 DPF systems.
Not to mention, catalytic converter thefts have been on the rise across the US. People cutting them off and scrapping them. I don't see a future for cats on semi trucks, but I could be wrongsupergreatguy, 77fib77, Arctic_fox and 2 others Thank this. -

And their diesel fuel has 3 times more sulfur than over here.
Diesel engine has a long way to go until reaches it's limits.
If it is still allowed to exist. To be seen. -
