<P>PROBLEM TO BE SOLVED: To simplify work for changeover between low-sulfur fuel and general fuel mounted in a machine such as a ship which drives a plurality of diesel generators. <P>SOLUTION: This exhaust emission control system includes a NOx catalyst 62 for promoting the reduction of NOx in exhaust gas from a plurality of generating engines 12, a urea water injection nozzle 47 for supplying NOx reducing urea water to the exhaust gas, and a power transducer 15 for detecting the concentration of NOx in the exhaust gas from the generated power energy of the generators 13 which are driven by the generating engines 12. The system also includes an engine controller 80 for controlling the drive of the generating engines 12, and a supply changeover solenoid valve 81 for selectively changing over fuel supplied to the generating engines 12 between low-sulfur fuel and general fuel. The engine controller 80 executes the changeover control of the supply changeover solenoid valve 81. <P>COPYRIGHT: (C)2010,JPO&INPIT |
