Summary:

The majority of unburned hydrocarbon emissions from vehicles occur during cold start operation of the vehicle before the catalyst system has heated to the point where it has reached high operating efficiency. One promising technology to reduce cold start hydrocarbon emissions is the catalyzed hydrocarbon trap. This paper presents the results of a vehicle, laboratory, and modeling study of the performance of this relatively new type of catalyst. A procedure to evaluate trap performance in the laboratory is presented that correlates well with trap performance on a vehicle. Additionally, a mathematical model of the catalyzed hydrocarbon trap is presented. This model utilizes laboratory determined parameters to calibrate the model for specific catalyzed hydrocarbon trap formulations to simulate the performance of that formulation on a vehicle. Data is presented that shows the model agrees well with vehicle data during the bag 1 portion of the Federal Test Procedure. In addition, modeling results are shown that predict the performance of a catalyzed hydrocarbon trap on a vehicle when such parameters as the trap size, position, substrate geometry, and trap composition are varied
