The SULEV (Super Ultra Low Emission Vehicle) Challenge 2003-26-0021
The key to meeting the SULEV (Super Ultra Low Emission Vehicle) standard is a combination of catalyst technology, vehicle calibration and system design. This paper outlines the design of the various components and their contributions to developing a vehicle emission control system that meets the SULEV standard. While it is certainly possible to meet the SULEV standard, it is critical to use appropriate catalyst technology, optimize the engine calibration, and develop a catalyst aging cycle that accurately mimics the on-road deactivation of the emission control system.
