Abstract |
This report presents the results of a laboratory correlation study between EPA and Audi-NSU Auto Union of Germany. An attempt is made to isolate equipment, procedure, and ambient differences which affect the degree of emission result correlation. A research vehicle was tested at both Audi and EPA with regard to HC emission correlation, with attention to some discrepancies in measurements of CO and NOx. Differences in dynamometers and ambient conditions seemed to be the most important factors affecting the degree of emission correlation. |
