Emissions Testing Tech Puts Pressure on Carmakers

In late September, Volkswagen admitted to using software that activated hardware to scrub nitrogen oxide (NOx) emissions during required emissions tests, but not during normal driving. The deception improved the cars’ gas mileage at the cost of emitting between 10 and 40 times the legal limit of NOx, a precursor gas to nitrogen dioxide (NO2), ammonia (NH3), and other gases that cause respiratory problems. In the last few years, newly maturing instruments of several kinds have converged on a single message: diesel exhaust in the real world is far higher than what carmakers advertise and what is permitted by the law in many countries.
