Emission Control Options for Heavy-Duty Engines

Emission control options for heavy-duty engines are evaluated for meeting the recently promulgated NO_X and particulate standards. Particulate options to meet these standards are evaluated in terms of emissions reduction, cost, and cost effectiveness. Control options include particulate trap, clean diesel fuel (low sulfur, low arontatics), methanol, and gasoline. The cost effectiveness for particulate control range from $3,000/ton to over $18,000/ton. These costs, however, are lower than many stationary measures.
