Analysis of Malfunctions of Diesel-Electric Transmission Locomotives (DET) and Methods of their Diagnostics and Elimination

Abstract

The article discusses the main malfunctions of diesel-electric transmission (DET) locomotives and methods for their diagnostics and elimination. Special attention is given to typical malfunctions of diesel engines, electrical transmission, cooling system, braking system, and mechanical components. The causes of these malfunctions and their consequences for safety and operational efficiency are presented. The article also describes modern diagnostic methods, including the use of diagnostic equipment, thermographic cameras, vibration sensors, and predictive diagnostics. Methods of fault elimination and recommendations for preventive maintenance to improve the reliability of DET locomotives are also discussed. The article aims to improve the operational characteristics of locomotives and reduce the risks of emergency situations.
