Compilation of Air Pollutant Emission Factors. Volume 2. Mobile Sources.Supplement A

摘要

A 'Compilation of Air Pollutant Emission Factors' (AP-42) reports data onatmospheric pollutants for which sufficient data exist to establish realistic emission estimates. The highway mobile source emission factors presented in this Supplement to the 4th edition of AP-42 (EPA, Sept. 1985) are based on EPA's MOBILE4 emission factor model (EPA, 1989), and provide emission factors for eight vehicle types and the highway vehicle fleet as a whole for a variety of different conditions (e.g., calendar year, average speed, temperature, fuel volatility, and operating modes). The supplement also discusses the algorithms used in MOBILE4 to estimate such emission factors.
