Abstract

Photochemical modeling has been used to determine the effect of fuels and vehicles on the urban ozone. Input data was lifted from the Auto/Air Quality Improvement Research Program (AQIRP). Multiday simulations were performed for gasolines in various AQIRP test matrices and for a methanol/gasoline blend. Among the gasoline changes which were recommended to reduce light-duty vehicles' role in ozone formation were olefin content and vapor pressure reductions and 90% distillation temperature.
