A CATALYTIC AUTOMOTIVE EMISSION CONTROL PROCESS WITH IMPROVED COLD-START BEHAVIOR |
摘要 |
A considerable reduction in hydrocarbon emissions during the cold start of internal combustion engines can be achieved if the actual exhaust gas catalyst is preceded in the exhaust pipe by a hydrocarbon adsorber of which the heat capacity is made greater than the heat capacity of the following catalyst through a suitable choice of material and configuration of the adsorber.
