发动机进气消声的研究现状及趋势分析
Analysis on the Present Situation and Trend in the Field of the Engine Intake Muffling
摘要
Abstract
Engine intake noise is an important part of automobile noise,and the national emission standards for automobile noise are becoming stricter and stricter,therefore,the research of engine intake noise elimination has a significant impact on the development of automobile industry.This paper firstly introduces the structure of the air intake system and the mechanism of the intake noise,and elaborates the control methods and principle of resistive muffler and resistance muffler to noise and their concrete structure.Then based on the research status of the intake muffler at home and abroad,the paper summaries the characteristics of each type of mufflers.After analysis,we can get the conclusion that under the premise of ensuring the intake efficiency,the hybrid muffler,which is the outcome of optimizing the internal structure of the resistance muffler and selecting the resistive soundabsorbing material of the resistance muffler,and can get more excellent silencing effect.关键词
