Exhaust Emission Rates for Heavy-Duty On road Vehicles in MOVES201X

Citation:

Exhaust Emission Rates for Heavy-Duty On road Vehicles in MOVES201X.

Description:

Updated running exhaust gaseous emission rates (THC, CO, NOx, CO2) for heavy-duty diesel trucks model year 2010 and later based on portable emission measurements from the manufacturer-run, heavy-duty in-use testing (HDIUT) program. Updated cold start emission rates and soak adjustments for starts for heavy-duty diesel trucks. Incorporation of the projected effects of the Heavy-duty Greenhouse Gas Phase 2 Program on heavy-duty truck emissions. Updated extended idle emission rates, and auxiliary power emission rates. Updated emission rates for heavy-duty CNG emission rates, and expanded use of the CNG emission rates to other heavy-duty source types in MOVES, beyond transit buses. Update humidity corrections for NOx exhaust emission rates.

Purpose/Objective:

Peer-review updated material in two technical reports for MOVES201X: 1. Exhaust Emission Rates for Heavy-Duty On-road Vehicles 2. Emission Adjustments for Temperature, Humidity, Air Conditioning, and Inspection and Maintenance for On-road Vehicles
