Abstract
Flow diverter methods and apparatus useful, for example, in adsorber systems capable of meeting the California ultra-low emission vehicle (ULEV) standard, are described, the adsorber systems incorporating a combination of a burn-off catalyst and a modified adsorber constructed with an open flow region of substantially unobstructed flow having a hole or a region of larger cell openings, the flow diverter acting to control exhaust flow through the adsorber to both increase adsorption and reduce the light-off time of the burn-off catalyst.
