UK university may have solved Diesel pollution problem

[happy1]

Loughborough University (UK) claims it has made a new system for reducing, and possibly eliminating, dangerous NOx emissions from diesel engines.

Their ACCT system improves existing SCR / Adblue based systems to also work with a cold engine.

All fine until people rip it off anywhere to make more power.. So many diesel vehicles on the road with no particulate filters its not funny..

Who cares.
What do you think happens to all the crap in the filter when it does a re gen... have you being inside a shed or garage while a re gen is going on?

SCR and DPF are two different things, buy yes when a DPF does a re gen indoors gtfo.

unfortunately I think the damage has been done at least for passenger car diesel power. can't see it lasting into st7. public pressure has turned against small diesels in their major Eu markets.

Here's some indoor regen. So these particles are the larger, more easily trapped ones being burned off. And, if they are burned off later (in someone's shed/lungs) does that mean that there's really no point to the things as the particulates are going into the atmosphere eventually anyway?

If SCR is getting so much better with ACCT, then there would be less deposits, less clogging up, and so on.

Diesels produce less CO2 per km than petrol engines which is needed, but the problem is NOX and particle removal systems such as SCR not working too well.

Have spent a quiet Monday evening learning a bit more... it appears Toyota were in the news in March with their DPFs on the 2.8

Any mech engineers or mechanics here? A Cadogan youtube comment suggested using air injection in the motor itself to clean the emissions - would this help? & also air injectors in the DPFs

This page describes the current SCR:

I'm not sure if an engine with SCR still uses recirculation of exhaust (EGR)?
