MOVES2010 Highway Vehicle Temperature, Humidity, Air Conditioning, and Inspection and Maintenance Adjustments

摘要

The emission rates in the MOVES model database represent a single (base) scenario of conditions for temperature, humidity, air conditioning load and fuel properties. MOVES is designed to adjust these base emission rates to reflect the conditions for the location and time specified by the user. MOVES also includes a methodology for adjusting the base emission rates to reflect the effects of local Inspection and Maintenance (I/M) programs. This report describes how these adjustments for temperature, humidity, I/M and air conditioning were derived. Adjustments for fuel properties are being addressed in a separate report. This report describes adjustments that affect running exhaust, start exhaust and extended idling emissions. The crankcase emission processes are chained to running exhaust, engine start and extended idling emissions, and thus are similarly affected by the temperature adjustments describe in this report. The impact of fuels, temperatures and I/M programs on vapor venting, permeation and liquid leaks is addressed in a separate report on evaporative emissions.
