| 摘要： | Emissions from tactical vehicle engines contribute to local and regional particulate matter (PM) air pollution. Emissions from these sources are not well-understood, and the Army requires methods/models to predict PM10 and PM2.5 emissions from these military-unique sources. To develop these methods/models, the mass and chemical speciation of tactical vehicle engine emissions need to be characterized, which may also be useful in a method to determine the Army's contribution to atmospheric PM concentrations at receptor sites of concern. Because much of the Army ground force uses JP-8 fuel (1), engine emissions from the tactical vehicle fleet may be established as a distinctive PM source category. The establishment of an Army-unique PM source is the first step in the development of a receptor- model-based method that can apportion the PM contribution from all sources, including the Army's. The objective of this program is to investigate procedures to be used in developing emissions factors for Army equipment. This project consists of the following tasks: 1. Perform a literature search to identify exhaust emissions data for JP-8 fuel used in Army engines and vehicles. 2. Examine the chemical and physical differences between JP-8 and diesel fuel (DF-2) (2). 3. Categorize groupings for Army wheeled and tracked vehicles to which a single emission estimation method/model can be applied. 4. Develop a plan for emissions testing of representative Army tactical vehicles using appropriate test cycle(s). |
