Abstract
At the request of the Dutch Ministry of Infrastructure and Environment a smart measurement system was developed to judge the real world NOx emission of heavy-duty vehicles. The measurement system uses a NOx - O2 sensor for the measurement of the tail pipe concentration of NOx and to estimate the tail pipe concentration of CO2 for diesel engines. A GPS measures the time-based vehicle speed profile over the test trip. Furthermore, a special data-evaluation method helps to reveal emission performance over the speed ranges of a vehicle. The method is based on collecting (binning) emissions of NOx and CO2 in speed intervals and calculates the CO2 specific NOx emissions for each interval.
