    Abstract: An exhaust gas treatment system for treating an exhaust gas. The exhaust gas treatment system includes a first section, a bypass section, and a common second section. The first section may include a first valve and at least one exhaust gas treatment component, such as, for example, a DOC and/or DPF. The bypass section may include a bypass valve and a heater that is configured to elevate the temperature of at least a portion of the exhaust gas. The second section is in fluid communication with the first section and the bypass section and includes a selective catalytic reduction system. Further, exhaust gas may be diverted into the bypass section when the exhaust gas fails to satisfy the threshold condition, so that the heater may elevate the temperature of the passing exhaust gas.

    Abstract: A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated.
