Table 2 Analysis of CO, HC and NO emissions from light-duty gasoline vehicles tested under ASM5024.
From: Potential of big data approach for remote sensing of vehicle exhaust emissions
Emissions | Maximum of raw data | Statistical average value of raw data | Cutpoints of emission concentrations for screening high-emitting vehicles | Statistical average value after screening out high emission vehicle data |
|---|---|---|---|---|
CO (%) | 12.77 | 0.23 | 0.82 | 0.14 |
HC (10−6) | 9886 | 169.26 | 735 | 47.7 |
NO (10−6) | 3968 | 396.62 | 1425.2 | 302.48 |
