Characterization of Off-Road Diesel Emissions of Criteria Pollutants
Abstract
The goal of this project is to identify and fill knowledge gaps concerning emission testing methods, emission factors and rates, and activities that create emissions for non-road military diesel engines. This requires the development of new measurement methods that quantify a larger number of chemical compounds and particle sizes, at concentration levels much less than the certification requirements, and for fuels and operating cycles that are not well represented by engine certification tests. Specific project objectives are: 1. Develop, test, and apply new methods for quantifying non-road emissions that more efficiently and realistically represent actual operations than engine dynamometer certification tests. 2. Develop source-, activity-, and fuel-specific emission rate estimates for representative Department of Defense (DoD) mobile and stationary diesel equipment, most of which is not used on public roadways. Emitted pollutants include carbon monoxide (CO), oxides of nitrogen (NOX), volatile organic compounds (VOC), particulate matter (PM, including PM2.5 [particles < 2.5 um aerodynamic diameter], and ultrafine particles [UP, particles less than 0.1 um aerodynamic diameter]), sulfur dioxide, (SO2), and ammonia (NH3). Chemical source profiles for PM2.5 are also quantified. 3. Determine how non-road emissions can be integrated with emissions modeling databases and software that estimate total diesel emissions.
