The purpose of this research is to quantify the compliance of on-road emission from a light duty diesel vehicle, based on a comparison to emission regulation standard. NO<SUB>x</SUB>, CO and THC emissions were measured using a portable device on a selected real-world driving route with a length of approximately 22 ㎞. On-road measurements were repeated by 10 times on a same route to reflect variability in traffic conditions. A test route was divided into 22 road links with length of 1 km to analyze emission results with higher spatial resolution.
The average emissions of NO<SUB>x</SUB>, CO and THC over total travel distance, which is approximately 220 ㎞, were quantified to be in compliance with emission regulation standards. Under higher spatial resolution, NO<SUB>x</SUB> concentration exceeded a standard in 92 links out of 220 links. The extended time in stop period and the stop-and-go driving cycle were identified as two important reasons for increased NO<SUB>x</SUB> emissions in observed cases. Heavy traffics showed higher NO<SUB>x</SUB> emissions than free flow. These results indicate that the real-world vehicle emissions might exceed the compliance level associate with traffic conditions.
Another interesting observation of this research is that the on-road emission characteristics can be independent to the average speed of road links with higher spatial resolution. Variability in on-road emission might not be fully described by solely relying on an average speed, because variability in traffic conditions and road conditions can influence on real-world vehicle emissions.
