Keeping the Heat on Cold-Start Emissions

    Research output: NRELMarketing

    Abstract

    NREL researchers, together with CRADA (cooperative research and development agreement) partner Benteler Industries, have produced an innovative new device, the variable-conductance-insulation (VCI) catalytic converter, that solves the problem of 'cold-start' auto emissions. This brief explains how VCI technology keeps the converter hot from one automotive trip to the next, thus greatly reducingtoxic emissions during the first minute or two (the cold-start period) that it takes your catalytic converter to reach its operating temperature of about 300 C.
