Fiat Chrysler seeks diesel emission certification from EPA

Mayne said this week's changes are different from the ones proposed before January 12, and FCA said today that the filing comes after "many months of close collaboration between FCA U.S. and EPA and CARB, including extensive testing of the vehicles, to clarify issues related to the company's emissions control technology".

Fiat Chrysler Automobiles NV filed a proposed fix to its diesel engines that the carmaker predicts will resolve negotiations with the Justice Department and other USA regulators.

The filing is the culmination of four months of work with the EPA and CARB after the federal regulator alleged the Italian-American automaker had installed software in 2014 to 2016 model-year editions of the diesel vehicles that violated clean-air rules.

On Friday, Fiat Chrysler said it was modifying Jeep Grand Cherokees and Ram 1500 diesel vehicles in the 2014 through 2016 model years with "updated emissions software calibrations".

Fiat Chrysler said it believes its application and proposed software fix, "should help facilitate a prompt resolution to ongoing discussions with the Environment and Natural Resources Division of the U.S. Department of Justice and other governmental agencies". The agency also stopped FCA from certifying its 2017 3.0-liter diesel model. The company plans to make the same modification to the emissions-control software in those model-year vehicles that it's applied to deploy for 2017 vehicles, if regulators approve. Regulators have said that in normal driving they emitted up to 40 times more smog-causing nitrogen oxide than the legal limit. Governments the world over have started investigations into Volkswagen and other diesel manufacturers that might be cheating on tests.

And the evidence has piled up that those high emissions levels were part of efforts to evade environmental standards. At the same time, the automaker has filed an application for diesel emissions certification of the 2017 Jeep Grand Cherokee and the 2017 Ram 1500.

Fiat Chrysler (FCA), attempting to reach a settlement with USA regulators following studies that show the automaker installed emissions-cheating software, has said that it will modify around 100,000 diesel vehicles.

Since the beginning, FCA has been clear in saying that the software is not a "defeat device", or there to intentionally fool regulators.

A 2013 study by Carder's team set off a chain of events that exposed Volkswagen's use of illegal software to hide excess emissions in diesel cars.

Researchers from the University of the Ruhr in Bochum, Germany, and at the University of California, San Diego, said this week they found evidence of a defeat device in a diesel Fiat 500X, a compact SUV sold in Europe.
