Measuring emissions from a demonstrator heavy-duty Diesel vehicle under real-world conditions - moving forward to Euro VII

The EU has introduced since the early 1990s a series of progressively more stringent emission regulations to control air pollution from the transport sector, commonly known as Euro standards. More recently, with the European Green Deal, the European Commission has indicated the intention to review the current air pollutant emissions standards. This study investigates the emission performance of an advanced demonstrator vehicle developed to meet the increasingly more stringent air pollution limits required. Emissions of currently regulated and unregulated components including: NH3, N2O, and SPN10, were studied in a very wide range of real world operative conditions. The performance of two new generation portable instruments for the on board measurement of N2O and NH3 were also evaluated in comparison with reference laboratory equipment. Similarly, the measurement accuracy available on-board of NOx sensors was also compared to laboratory reference. The vehicle presented low emissions of NOx and NH3 and relatively low emissions of N2O in a broad range of operative conditions which however resulted in a large variability in emissions.
