A Comparison of Extruded Powder Metal Heating Elements and Metallic Foil Heating Elements 962081

California Ultra Low Emission Vehicle (ULEV) standards call for a significant reduction in the amount of harmful gases that enter the environment from vehicle exhaust. The Electrically Heated Catalyst (EHC) is a possible solution to reduce emissions. A competitive analysis benchmarking study was completed in order to find an optimum EHC design that will perform to ULEV standards. Four suppliers submitted samples and the EHC designs were rigorously tested for temperature, pressure drop, and emissions performance while being aged at different levels.
