Diesel Engine Emissions Control for the 1990's

The purpose of this paper is to discuss emissions control needs for heavy duty diesel truck engines for the 1990's. This paper will focus on key technological advances in engine technology, fuels and lubricants, and aftertreatment needed to meet the more demanding future standards. An optimum solution will involve the cooperative efforts of EPA, the petroleum industry, truck manufacturers, engine and component manufacturers, as well as truck users. Diesel engine emissions control will be an important factor in providing best value truck engines for the 1990's.
