In a machine wherein a plurality of diesel generators are driven such as a marine vessel, a switching operation from a low-sulfur fuel to a general fuel loaded on the machine (and vice versa) is simplified. An exhaust gas purification system which is equipped with a NOx catalyst (62) accelerating the reduction of NOx contained in an exhaust gas from a plurality of electric power-generating engines (12), a urea-water injection nozzle (47) supplying urea-water for reducing NOx to the exhaust gas, and an electric power transducer (15) detecting the concentration of NOx in the exhaust gas on the basis of the electric power generation by electric power generators (13) that are driven by the electric power-generating engines (12). The system is f...
