1. Thermal parameter analysis method. The working state of the diesel engine can be judged by analyzing the thermodynamic parameters. The thermodynamic parameters of the diesel engine include cylinder pressure diagram, exhaust temperature and lubricating oil temperature. By analyzing these parameters, the working state of the diesel engine can be judged and confirmed. is in a stable state. A large amount of information can be analyzed from the pressure work diagram, and the indicated work, compression pressure and pressure rise rate can be calculated. At the same time, the combustion quality and the working conditions of each cylinder can be judged, and the performance of the diesel engine can be comprehensively reflected. The analysis can realize the monitoring of the state of the diesel engine.
2 vibration analysis method. Through the measurement, analysis and processing of the vibration signal in the working process of the diesel engine, the result of the running state of the diesel engine is finally obtained. This method is characterized by fast detection speed and can accurately reflect the running state of the diesel engine. The process of diagnosing diesel engine faults using this method is information collection, information processing, state judgment and forecast.
3 oil analysis method. By measuring the metal content in the oil, the wear degree of the diesel engine can be judged. If the diesel engine is found to have serious wear, it is necessary to replace the spare parts in time. If the individual parts of the diesel engine are severely worn, the iron filings will fall into the lubricating oil. By analyzing the ferrogram and spectrum of the lubricating oil, the severity of the fault can be judged.
