Abstract

As the main force of logistics and transportation, the reliability of the engine of heavy-duty trucks directly affects the transportation efficiency and cost. Scientific fault diagnosis technology is the key to improving maintenance efficiency and reducing operating costs. Based on the analysis of the common types and causes of heavy-duty truck engine faults, this paper focuses on the key points of diagnosis of several types of major faults. Studies have shown that carbon deposition can be prevented through reasonable cleaning and improving fuel quality. Noise faults need to be carefully checked for parts and tear. If the engine oil deteriorates, the oil must be replaced in time and the working condition must be optimized. For start-stop faults, circuits and components should be repaired in a targeted manner. The application of these diagnostic technologies can greatly improve the accuracy and efficiency of heavy-duty truck engine maintenance, and provide a strong guarantee for the efficient operation of vehicles.
