Evaluation of In-Line Adsorber Technology 970267

To meet tightening emissions standards, alternate pollution abatement technologies are necessary, such as an In-Line Adsorber (ILA) system.
The ILA has a first catalyst, an adsorber, and a second catalyst. A diverter directs exhaust gas through the adsorber to capture unconverted hydrocarbons until the first catalyst reaches light-off temperature. The ILA system was designed so that the second catalyst becomes active concurrent with the adsorber hydrocarbon desorption.
The system was evaluated using the FTP test with two different secondary air strategies on 3.8 liter V6 and 4.0 liter V8 vehicles. The ILA system performance consistently reduced ∼50-60% of cold start hydrocarbon emissions. This study examined a simplified ILA system designed to operate with a commercial secondary air pump powered by the engine.
