Development of NOx aftertreatment for renault diesel engines

The achievement of future emission standards for diesel engines requires the use of NOx aftertreatment systems, in addition to engine internal improvements. The NOx trap system, developed by Renault, enables heavy vehicles like minivans to reach future emission standards and maintain the diesel CO2 advantage. Equipped with the NOx trap, the Espace dCi 175 complies with Euro 5 and looks even further ahead with a technology that is ready for Euro 6.
