they reduce the amount of NOx by reducing the amount of air going into the explosion chamber. less air -> less nitrogen -> less NOx, but also less expansion force.
AFAIK all car makers cheat here. under realistic conditions no diesel car would pass the current limits, and somewhere I read most cars of todays would not even pass 1992 limits. This is a long ongoing gaming of the system.
