The Effect of the High Boost and High EGR on the Heavy Duty Multi Cylinder Diesel Engine with Low Pressure Loop EGR.

-The Evaluation using the Transient Test Cycle-

Abstract

For the 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 are installed in the 6 cylinder engine. Both the low-pressure loop EGR system and the high-pressure one are adopted for the reduction of NOx and PM with the higher EGR rate. In this study SCD Engine is tuned by steady state test and finally the SCD Engine is tested by JE05 transient test cycle.
