診断装置。 Selectively capture output signals from a vibration sensor and a sound pressure sensor attached to a main operating part of a reciprocating engine, a load sensor provided at an output part of the reciprocating engine, and the vibration sensor and sound pressure sensor. In addition, a control means is provided with a filter function for extracting arbitrary frequency components from these signals, and based on the output signal from the load sensor, correction is made to the output signals from the vibration sensor and the sound pressure sensor processed by the control means. and a data processing analysis means for dividing these signals into arbitrary frequency bands, and an abnormality detection means for detecting an abnormal state by comparing the output signal from the data processing analysis means with a control reference value. An abnormality diagnosis device for a reciprocating engine characterized by:
