  • Method for diagnosing a catalytic device of an engine exhaust gas after-treatment system
    Patent number: 8538721
    Abstract: A method is provided for estimating an aging index of the catalytic device. There estimation of the aging index includes, but is not limited to determining the catalytic device operating temperature, determining an aging factor as a function of at least the determined operating temperature, determining the time period spent by the catalytic device at the determined operating temperature, calculating a contributing aging coefficient as a function of the aging factor and the time period, and increasing a cumulative aging parameter by adding the contributing aging coefficient.
