Technologies for Improved Emission Potential in a Small Displacement Volume Passenger Diesel Engine 2009-01-1444

Diesel engine has been attractive for its high thermal efficiency with the large penetration into the passenger car. Main progress of diesel engine is in the emission control and performance potential. New technologies are introduced to cope with the requirement toward cleaner engine. Although new technologies are effective in emission reduction, their application should be approached carefully because they have both positive and negative effect on fuel economy and cost. Therefore, it is important to understand the characteristics of the individual technology and optimize efficiently. It is more required in the small displacement engine. In this paper, several technologies are presented and their characteristic behaviors are investigated for a small displacement volume passenger diesel engine. Thereby, emission potential is improved to comply with upcoming emission standards.
