What Year Did Emissions-Era Engines Get Better

hell id buy the 07-11 first. easier to delete

 

Get better is the wrong wording. I would say its less they got better and more mechanics and drivers found workarounds to keep them moving.

 

Any thing from 2002 -2013 were bad. I hear people say 2014 and after are good. The newer the better. Cummins has trouble with so much soot in engine it clog oil to top of engine and cams would go bad. Then they has trouble with fuel pumps beit ceramic and they would come apart and destroy the engine.

Detroit Diesel engines were pretty good, the emissions box still go bad today around 600,000 and it $12,000 to replace the emissions box.

First years of EGR had all kinda of trouble. The first years of DPF has trouble running to cold and clogging . The DEF fluid in 2011, Detroit had air system to run their system, it was bad because when waters in air tanks, it then got pump into DEF system messes it all up. So they switched to electric pump now.

 

I hear the 2023 model has the bugs worked out lol I got out of a 2018 and got into a 2003 best move I made . I don’t get towed anymore and no worries about frozen def at pumps is a bonus here in Canada .

 

Totally subjective.

Idling is pretty much the kiss of death for emissions engines, so APU'S have a key roll.

I just sold my 2012 ISX, it was 100% original. 750K miles, except the aftertreatment, that was overhauled by Cummins at 650K miles.

How you drive, maintenance, and idling are key factors.

2016 is when a lot of known issues got removed from Cummins and Detroits.
