Diesel-Powered Equipment Properties and Activity Database for DoD Off- Road Sources

摘要

A database of Department of Defense diesel engine powered off-road equipment was developed using Micro-soft Access database development tools. The database contains information about fuels, equipment, engines, inventories, usage, and fuel consumption that was obtained from many disparate sources. This database was developed to support the SERDP-funded project Characterization of Off-Road Emissions of Criteria Pollutants (WP-1336). The database was used to prioritize the equipment contained in the WP-1336 test matrix and will later be used as a source of information for the WP-1336 engine emission estimation tool. Data analysis has shown that the top ten fuel consuming engines account for more than 90 percent of fuel usage for the Army and more than 80 percent for the U.S. Marine Corps. Therefore, emission tests performed on a limited number of off-road diesel engines can provide a fairly complete picture of emissions from the entire population of military off-road sources. The database includes an interface that allows users to view data in onscreen forms or analyze data using built-in reports. The database and interface are intended as resources for anyone interested in examining, filtering, querying, or analyzing the collected data.
