Feasibility and Cost-Effectiveness of Controlling Emissions from Diesel Engines in Rail, Marine, Construction, Farm, and Other Mobile Off-Highway Equipment

摘要

Diesel engines in off-highway vehicles and other off-highway mobile equipment, while less numerous than those in highway trucks and buses, are still significant contributors to oxides of nitrogen (NOx) and particulate inventories in many urban areas. These engines are presently exempt from any emissions control requirements. Consequently, they produce far more pollution per unit of fuel input or work output than the otherwise similar emission-controlled engines used in on-highway vehicles. The recent promulgation of stringent NOx and particulate emission standards for diesel engines in on-highway vehicles has drawn attention to diesel emissions in general, and has raised the question of whether similar emissions standards might be appropriate for off-highway diesel engines.
