Abstract
Description
technical field
[0001] The invention belongs to the technical field of automobile intake systems, and in particular relates to an installation structure of an air filter intake pipe and a resonant cavity used in the automobile intake system. Background technique
[0002] As a means of transportation, automobiles play a very important role in modern industrial society. With the development of society, people have higher and higher requirements for the comfort and environmental protection of automobiles, one of which is the requirement for noise. The noise of the air intake system is one of the most important noise sources of the car. The noise mainly refers to the noise at the air intake. This noise source is very close to the cabin, so it contributes a lot to the noise inside the car. Mouth noise is also the most important source of pass-by noise in automobiles. In order to reduce the influence of air intake noise on interior noise and pass-by noise, in addition to ration...
