Abstract
A system and method of normalizing an emissions threshold catalytic brick 302 without a mileage accumulation step is used to evaluate an on-board diagnostics for an exhaust system. The method comprises normalizing a emissions threshold catalytic brick 302 by placing the emissions threshold catalytic brick 302 in a exhaust gas circulation oven, such as a retort chamber 300, immediately after an oven-aging and chemical aging process wherein the emissions threshold catalytic brick 302 is saturated with a exhaust gas at a predetermined rate and at a predetermined temperature for a specified period of time based upon the characteristics desired for the emissions threshold catalytic brick. Additionally, a method for evaluating on-board diagnostics of an exhaust system using an emissions threshold catalytic brick 302 based upon the characteristics of the exhaust system that it will be placed in is also contemplated.
