2. Post-treatment technologies to meet regulatory requirements

Pollutant reduction involves improving emissions at source, i.e. those produced in the combustion chamber, as well as improving after-treatment systems and the strategies for putting them into action. Here, we'll be focusing on progress in the latter area.

To find out more about the challenges posed by the new regulations Euro 6.d-temp To do this, simply compare the speed/torque points covered on the NEDC homologation cycle, those concerned by the new WLTC cycle and those linked to an "average" RDE run in an engine field: the coverage (figure 6 ) required for emissions control is far more...
