Analysis of motor vehicle emissions in a Houston tunnel during the Texas Air Quality Study 2000

摘要

Measurements from a Houston tunnel were used to develop fuel consumption-based emission factors for CO, NO_x, and non-methane organic compound (NMOC) for on-road gasoline vehicles. The Houston NO_x emission factor was at the low range of emission factors reported in previous (primarily pre-1996) tunnel studies while the NMOC emission factor was slightly higher than that reported in the previous tunnel studies.
