摘要
An exhaust gas treatment system for an internal combustion engine is provided, having an exhaust gas conduit, a reductant source, a temperature sensor, an intake mass air flow sensor, and a control module. The exhaust gas conduit is in fluid communication with, and is configured to receive an exhaust gas from the internal combustion engine. The exhaust gas contains oxides of nitrogen (“NOx”). The reductant source is in fluid communication with the exhaust gas conduit and is configured for injecting an amount of reductant that is released into the exhaust gas conduit. The temperature sensor is situated in the exhaust stream for determining a temperature of the exhaust gas at the reductant source. The intake mass air flow sensor measures an air mass flow entering the internal combustion engine. The control module is in communication with the reductant source, the temperature sensor, and the intake mass air flow sensor.
