Abstract: PURPOSE: A poisoning detection system and method for an exhaust purifier is provided to superlatively maintain the function of a catalyst without extra manipulations, thereby reducing the amount of exhaust gas. CONSTITUTION: A poisoning detection system for an exhaust purifier includes a temperature sensor(100) and a controller(200). The temperature sensor is placed at a distribution line for exhaust gas. The temperature sensor is equipped with a catalytic substance. Exothermic reaction is generated between contaminants in the exhaust gas and the catalytic substance. The controller stores a reference temperature value for the temperature sensor. The controller raises the temperature of the exhaust gas by controlling ECU(Electronic Control Unit)(300) when the temperature value of the temperature sensor is dropped as much as a certain level. The controller determines the heat deterioration of the catalytic substance when the value of the measured temperature of the exhaust gas, which is raised by the controller, does not reach the reference temperature value, and then updates the reference temperature value into the value of the measured temperature. The controller transmits a warning signal when a period for temperature raising requirement through the ECU become shorter.
