Study on the Detection of Misfiring Cylinder in a Heavy Machinery Multi-Cylinder Diesel Engine under the State of Rotational Fluctuation 2006-01-3550

Mechanical problems of heavy machinery can cause serious losses [1, 2]. And a diesel engine with a misfiring cylinder is likely to break down in a short period of time. In this system, a minimum number of sensors will be installed in the diesel engine to build a diagnosis system which detects anomaly behavior by analyzing the acceleration waveform using statistical analysis of R.M.S. value. This method is superior to traditional methods in point of simplicity, and this system can be applied to the ready-made machinery easily. This system will make it possible to manage the engine from a remote location by data transfer [3]. However, previous system was limited in case of an idling state of the engine. It was successful to detect misfiring condition of cylinder on the engine under the state of rotational fluctuation in this research.
