This paper introduces the analysis process and optimization of the turbocharger actuator system wear issue during the development of VGT turbocharger for the first time on a 1.0 L gasoline engine. After the engine performance degradation, based on the data analysis, it is found that the actuator system is abnormal. Based on the disassembly inspection, it is found that the actuator system is seriously worn. At last, the problem is solved by optimizing the actuator. There are two key points in this paper: 1. Show the characteristics of engine test data when VGT actuator is worn, so as to quickly find out the cause of engine performance degradation in the future; 2. Clarify the design points of VGT actuator system to avoid similar failures in the future.
