The realisation of an on-board emission measuring system serving as a R&D tool for ultra low emitting vehicles

Abstract
The negative impact of deteriorating air quality on public health etc. is receiving growing attention. As a result, the contributing emission sources are increasingly regulated. Thus, the emissions of road transport - being one of the largest contributors - are under constant pressure. As such, the evolving legislation on emissions of new cars is forcing to ultra low emitting vehicles. To assist in the development of those vehicles an on-board measuring system capable of determining ppm level emissions of carbon monoxide (CO), total hydrocarbons (THC) and nitrogen oxides (NO
