Volkswagen cheated on their emissions and is paying the price

Now it seems that Fiat/Chrysler was caught doing this too. From Yahoo/Reuters:

EPA accuses Fiat Chrysler of excess diesel emissions
The U.S. Environmental Protection Agency on Thursday accused Fiat Chrysler Automobiles NV of illegally using hidden software to allow excess diesel emissions to go undetected, the result of a probe that stemmed from regulators' investigation of rival Volkswagen AG.

FCA shares plummeted as the maximum fine is about $4.6 billion. The EPA action affects 104,000 U.S. trucks and SUVs sold since 2014, about one-sixth the vehicles in the Volkswagen case.

The EPA and California Air Resources Board told Fiat Chrysler it believes its undeclared auxiliary emissions control software allowed vehicles to generate excess pollution in violation of the law and each issued notices of violation.

Oopsie - this would indicate collusion between companies. I wonder who makes the controller computers for the TDI vehicles - is the same company making all of them? Software? The problem:

Regulators said FCA failed to disclose engine management software in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines. The undisclosed software results in increased emissions of nitrogen oxides (NOx).

And the ridiculous thing is that they could eliminate the NOx problem by adding a urea system to the exhaust. My truck has this - I fill up on Diesel Exhaust Fluid every couple thousand miles and it injects drops of this into the hot exhaust. The ammonia in the urea forms with any NOx to produce water vapor and nitrogen gas. This way, you can run the diesel engine at peak efficiency instead of having to run it very lean to minimize NOx production. NOx produces smog and is irritating to mucus membranes - lungs, eyes, etc....
