Based on the problem of abnormal noise of a turbocharger model in acceleration condition, the study starts from the spectrum characteristics of the abnormal noise. Combined with subjective evaluation and analysis of transmission paths and noise and vibration frequency of various components of engine compartment, this paper elaborates on the excitation characteristics of the turbocharger. According to the generation mechanism of abnormal noise, considering factors such as spatial layout, performance matching and cost constraints, a pneumatic buffer has been set reasonably to eliminate or reduce the influence of turbocharger abnormal noise on riding comfort during acceleration. By integrating principle, analysis and improvement, a set of diagnosis methods for abnormal noise of turbocharger is developed. After being improved and verified, the proposed methods have been applied.
