Title:
EXHAUST EMISSION CONTROL SYSTEM, METHOD FOR OPERATING THE SAME, AND METHOD FOR MONITORING THE SAME
Document Type and Number:
Japanese Patent JP3697668
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust emission control system, and an exhaust emission control method.
SOLUTION: This exhaust emission control system having a simple structure, a sufficient control option, and a very extensive and simple monitor concept reduces nitrogen oxides present in an exhaust emission from an internal combustion engine with gaseous ammonium using an SCR catalyst converter. The function of the exhaust emission control system 9 is monitored by referring to elements (connection parts, valves and sensors) themselves of pipings having the connection parts, valves and sensors, and using an adequate control circuit via an evaluation/control device 8.
