ABSTRACT:
An exhaust gas emissions control system lowers cold-start hydrocarbon emissions by using heat exchange structure to lower the temperature of exhaust gas prior to the exhaust gas passing through a hydrocarbon adsorbent and using the extracted heat to heat a catalytic converter to its light-off temperature. In some embodiments, multi-component hydrocarbon adsorbers effective under different operating conditions further reduce cold-start hydrocarbon emissions.
