| 摘要： | The report presents a study of transit bus life cycle cost (LCC) analysis, and projected transit bus emissions and fuel economy for 2007 model year buses. It covers four bus types: diesel buses using ultra low sulfur diesel (ULSD), diesel buses using B20 biodiesel (20%biodiesel and 80%ULSD), compressed natural gases (CNG) buses, and hybrid diesel-electric buses. LCC factors included capital costs (bus procurement, infrastructure, and emissions equipment) and operation costs (fuel, propulsion-related system maintenance, facility maintenance, and battery replacement) available from the literature. The report addresses how to estimate these costs, and presents these data in units of dollars per bus mile and dollar per bus seat mile. Tailpipe emissions (particulate matter (PM), nitrogen oxides (NOx), non-methane hydrocarbon (NMHC), and greenhouse gas (GHG)) and fuel economy estimations were based on recent emissions and fuel economy studies, and adjusted with best engineering approach. GHG emissions were also computed on both a well-to-tank and tank-to-wheels emissions. The GHG reported were considered to be only carbon dioxides (CO2) and methane. The emissions data are reported in units of grams per mile, and fuel economy data are in miles per gallon. |
