| 摘要： | This is the third in a series of vehicle and engine compliance reports issued by the U.S. Environmental Protection Agency (EPA) Office of Transportation and Air Quality (OTAQ). These reports offer a convenient reference to the data that OTAQ collects in implementing emissions regulations for vehicles, engines, and other motorized equipment. The environmental programs OTAQ implements apply to virtually every vehicle, engine and gallon of transportation fuel sold in the United States. It is our job to make sure that these regulated mobile sources comply with emissions and fuel economy requirements. OTAQ's role in ensuring comprehensive compliance is essential to realizing national air quality and public health goals. The purpose of the compliance reports is to offer a snapshot of compliance activity over a given time frame. The years covered by the 2009-2011 Compliance Report represent a period of significant transition in the mobile source program. Stringent new emission standards took effect for many vehicle and engine categories, including motorcycles, heavy-duty highway engines, nonroad compression-ignition and marine diesel engines, locomotives, small spark-ignition and marine spark-ignition engines, and recreational vehicles. |
