CBC: U of M engineer explains how Volkswagen cheated on emissions tests

September 24, 2015 — 

As the CBC reports: Volkswagen rigged their emissions tests using a device familiar to car engineer and University of Manitoba associate professor Ed Hohenberg.

The automaker cheated using something known as a defeat device, which makes a car’s engine run cleaner when undergoing emissions testing, he said.

“The engine software recognizes when the engine is being run through the EPA emission testing procedure.”
