Advanced Electronics and Control Technologies for Fuel Efficient Low Emission Diesel Powertrains 2004-21-0083

The inherent fuel economy benefits of diesel powertrains over gasoline offer significant potential for reduced energy consumption and provide vehicle manufacturers with a viable method of improving Corporate Average Fuel Economy (CAFE). However, achieving the stringent NOx emission levels of upcoming LEV II and Tier 2 standards, while retaining low fuel consumption and satisfying consumer demand for higher performance, presents significant technical challenges. For diesel powertrains to succeed in the US light duty vehicle market, manufacturers must apply engine and exhaust aftertreatment technologies which meet the technical demands within a viable business case. This paper outlines the trends in advanced electronics and controls for diesel powertrains and the role of these technologies in enabling diesel as a viable fuel efficient option for the US light duty vehicle market.
