Abstract | The Environmental Security Technology Certification Program (ESTCP) funded a three-year project to obtain air pollution emission factors for commonly used Department of Defense (DoD) diesel engines fueled with various types and blends of biodiesel. The project included the measurement of the regulated air emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM). Testing was performed in accordance with Environmental Protection Agency (EPA) testing standards and duty cycles, both in the lab and in the field. The project focused on B20 biodiesel blends, since this is the blend of biodiesel used in military vehicles. The project results for the regulated emissions werre that at the B20 level, there were no consistent trends over all applications tested. Within the context of the test matrix, no differences were found between the different yellow grease based biodiesels (YGA and YGB) and soy-based biodiesel feedstocks. Although the testing was not able to identify statistically significant air pollution benefits for the use of B20 biodiesel, from a lifecycle Cost standpoint, the use of B20 is the most cost effective method for DoD fleets to meet their alternative vehicle requirements. Using B20 in place of petroleum diesel involves no new infrastructure requirements nor additional environmental compliance costs. |
