Report: Volkswagen Made Emissions Defeat Devices For Several Engines
Newer-Generation EA288 Engine May Also Be Involved
The news and scrutiny surrounding Volkswagen has just gone from bad to worse for the company, with the revelation that the “defeat device” scandal may not be limited to the EA189 as originally thought. According to a Reuters report, defeat software was also installed on the newer-generation EA288 TDI engine and may have also been installed on other engines as well. The EA288 has a urea fluid selective reduction catalyst (SCR) system designed to better control NOx emissions than the NOx trap design utilized by most applications of the earlier-generation EA189 engine.
The number of engines and models affected, along with the number of personnel aware of and directly involved in the emissions cheating scandal could affect the ultimate fines levied by the U.S., European Union, and other regions where Volkswagen is under investigation. Sales of 2016 TDI models are on indefinite hold in the U.S. until U.S. and California regulators can conduct on-road tests and verify the vehicles meet emissions standards. Volkswagen earlier withdrew its certification application for 2016 diesel models in the aftermath of the crisis.
The scandal has also put other automakers under scrutiny and has delayed the introduction of other new diesel models such as the Chevrolet Colorado and GMC Canyon with the 2.8L Duramax I-4. The trucks are undergoing on-road emissions testing by state and federal regulators to ensure compliance before being approved for sale.
