Abstract:
An exhaust gas cleaning system comprises a reducing agent injection module installed in an housing mounted in an exhaust pipe through which an exhaust gas is discharged, the reducing agent injection module being configured to inject a reducing agent into the housing, a selective catalyst reduction device installed in rear of the reducing agent injection module and configured to catalytic react the reducing agent with nitrogen oxide included in the exhaust gas to reduce the nitrogen oxide, a differential pressure sensor to detect a differential pressure between a pressure in the housing in front of the selective catalyst reduction device and a pressure of the housing in rear of the selective catalyst reduction device, and a control device to receive the pressure information from the differential pressure sensor and to output a first warning signal when the detected differential pressure is lower than a predetermined pressure.

Claim (Index 10):
A method of monitoring an exhaust gas cleaning system, comprising:\n detecting a differential pressure of an exhaust gas between front and rear of a selective catalytic reduction device and concentration of nitrogen oxide included in the exhaust gas; calculating conversion efficiency of nitrogen oxide of the selective catalytic reduction device from the detected concentration information; determining whether or not the selective catalytic reduction device is in an abnormal state, based on the calculated conversion efficiency and the detected differential pressure; and outputting a warning signal when it is determined that the selective catalytic reduction device is in an abnormal state.
