- Summary:
- AbstractA SULEV proposal was investigated for a Hyundai Elantra 1.8L Nu Engine, combining advanced catalyst technologies with optimized engine management control. A washcoat system using 20% less PGM loading and an optimized EMS calibration were developed to meet the 50% development target of the LEV III SULEV30 standards. This paper highlights revisions made to the new control and catalyst systems which include, 1) improved light-off time and cold-start emissions, 2) optimized cold lambda control, 3) reduced number of fuel cut events, 4) a new catalyst technology to match exhaust gas characteristics, and 5) a Pd-only front catalyst with reduced PGM
