Abstract: The purpose of this paper is to present a taxonomy of fuel use and pollutant emissions rates for heavy duty diesel (HDD) equipment to assist equipment managers in estimating the energy and environmental effects of their ...

Abstract: It is difficult to quantitatively assess the impact of engine idling on fuel use and emissions of construction equipment because of a lack of sufficient data. This paper presents a methodology for evaluating the impact of ...

Abstract: Construction vehicles are a source of nonroad mobile air pollutant emissions. Emissions from construction vehicles are typically quantified based on steady-state modal engine dynamometer tests using uninstalled stationary ...

Abstract: Commercial construction operations are heavy users of nonroad equipment and diesel engines. These engines are large contributors of carbon dioxide (

Abstract: Nonroad construction vehicles and equipment powered by diesel engines contribute to mobile source air pollution. The engines of this equipment emit significant amounts of carbon monoxide, hydrocarbons, nitrogen oxides, and ...

Abstract: Construction operations are highly energy-intensive and account for significant environmental impacts, including greenhouse gases (GHG) and other engine exhaust associated with material procurement/delivery and on-site ...
