This study is that it watches operating state of the fishing boat engine and diagnoses the condition as a torque rich operation. The combustion analysis in a torque rich was done by first using the heat release rate for that. Next, to detect a torque rich, the analysis that used the performance data of the engine was done. In addition, the method of detecting a torque rich in handily and high accuracy based on the vibration acceleration in which a single acceleration pick up was able to be installed in the surface of the a cylinder head was examined.
