Off-cycle, Real-World Emissions of Modern Light Duty Diesel Vehicles

Popis výsledku v původním jazyce

Four cars and one van were tested on a chassis dynamometer and/or on the road with a portable, on-board emissions monitoring system capable of online measurements of particulate and gaseous emissions. On all cars, operation at speeds and acceleration rates in excess to those within the applicable certification NEDC cycle resulted in higher concentrations of nitrogen oxide (NO) and particulate matter (PM). High-speed driving in excess of 120 km/h resulted in a marked increase in NO and PM concentrations,with further increases past 130-140 km/h. In urban driving, highest PM concentrations occurred at the onset of and during accelerations from low rpm. Aggressive, performance driving resulted in substantial increase in NO and PM emissions per kg of fuelcompared to normal driving. No marked increases outside of NEDC regimes were, however, observed on one van. The results support the arguments against increase in 130 km/h freeway speed limits and for augmenting the EU light vehicle certif
