OS-A1: Effects of High Boost and High EGR on the Super Clean Diesel Engine : Evaluation using the Transient Test Cycle(OS-A High Efficiency and Low Emission Engine by Variable Mechanism,Organized Session Papers)

Abstract

For next-generation low-emission vehicles, the Super Clean Diesel (SCD) Engine has been researched and developed. Many devices using the concept of high boost and wide range and high EGR compared with a current system were installed in the six-cylinder engine. Both the low-pressure loop EGR system and the high-pressure one are adopted for reduction of NO_x and PM with the higher EGR rate. In this study, the SCD engine is tuned using a steady state test. Finally, the tuned SCD Engine is tested using the JE05 transient test cycle.
