Summary:

A new HC adsorber system was developed to achieve California SULEV emission standards for a V8 5.0-liter engine application (id est LS600hL).A HC adsorber system was first released on 2001 PZEV Prius (1.5-liter engine) in U.S.A. For the 5.0L application the substrate volume of both catalyst and adsorber had to be enlarged for a large volume displacement. Prius-type adsorber system could not be adopted for LS600hL because of the problems of installation. So, a new constructional adsorber was proposed.However the increase of gas flow into the adsorber substrate was a problem for desorption. The gas flow into the adsorber substrate was found to be controllable by the specification adjustment of the "throat" and "retainer" parts of adsorber system. Thus the rapid desorption was successfully reduced, and the HC adsorber system achieved a 50% reduction of HC emission
