VW did it

Renault probably did it

These guys probably did

I think there was a point where regulators said "diesel puts out lung damaging levels of pollutants killing X people a year. We shall either ban diesel engines ... or make manufacturers make diesel engines that don't pollute that badly"

So they set a safe level.

And no manufacturer has been able to achieve the technology to meet that level.

I know some manufacturers claim they can, but honestly that's like a cyclist claiming that they won the Tour De France without drugs. After so many cyclists have been caught (about half since 1990) it's really hard to take the drug free claim seriously - just as it's hard to take the "our diesel engine does it really honestly guv"

Is there any detailed information anyone can find on what they allegedly did, at a technical level? "Defeat device" is such a broad category of term that it's useless for understanding the details of what it's claimed they did.

The Justice.gov writeup [0] isn't any better.

> The company allegedly installed defeat devices on 630,000 model year 2013 to 2019 RAM 2500 and 3500 pickup truck engines. The company also allegedly installed undisclosed auxiliary emission control devices on 330,000 model year 2019 to 2023 RAM 2500 and 3500 pickup truck engines.

I'd be interested in reading technical details on what, exactly, they did or didn't supposedly do.

One more reason it's time to transition away from burning stuff to produce energy.

What's so much worse is that this isn't the first time they've been caught doing this shit: https://www.epa.gov/enforcement/cummins-engine-company-diese...

That enforcement action is from 1998. There was even a consent decree but they've been doing this bullshit for a quarter century. It isn't a small isolated incident, it's literally built into the culture of the company. We need a corporate death penalty for repeat offenders like this.

This isn't even the first time Cummins has been hit with the largest settlement for emissions controls defeat devices![0] [0] https://web.archive.org/web/20151002043823/http://www2.epa.g...

Wow, and then had the audacity to continue the practice beyond that? That fine should be significantly more severe…

Best I have off hand is one of the example recall notices which just says "software update" for the emissions calibration:
