Abstract

Each element of the exhaust system has a different function. The element that has the greatest impact on reducing the noise associated with exhaust gas discharge is the final silencer. The design of the final silencerr has a significant impact on vehicle noise. The paper presents the study of the impact of modifications of the final silencer with a construction other than the factory one on the noise emission level of the vehicle. The tests were carried out in accordance with the Polish standard PN-92/S-04051 regarding the permissible level of external noise of vehicles.

分析了汽车排气消声器结构变化对噪声排放水平的影响

排气系统的每个元件都有不同的功能。对降低与废气排放有关的噪音影响最大的元件是最终消声器。终消声器的设计对车辆噪声有重要影响。本文研究了采用非出厂结构改造终消声器对车辆噪声排放水平的影响。测试是按照波兰标准PN-92/S-04051进行的，该标准规定了车辆外部噪声的允许水平。

期刊介绍： MATEC Web of Conferences is an Open Access publication series dedicated to archiving conference proceedings dealing with all fundamental and applied research aspects related to Materials science, Engineering and Chemistry. All engineering disciplines are covered by the aims and scope of the journal: civil, naval, mechanical, chemical, and electrical engineering as well as nanotechnology and metrology. The journal concerns also all materials in regard to their physical-chemical characterization, implementation, resistance in their environment… Other subdisciples of chemistry, such as analytical chemistry, petrochemistry, organic chemistry…, and even pharmacology, are also welcome. MATEC Web of Conferences offers a wide range of services from the organization of the submission of conference proceedings to the worldwide dissemination of the conference papers. It provides an efficient archiving solution, ensuring maximum exposure and wide indexing of scientific conference proceedings. Proceedings are published under the scientific responsibility of the conference editors.
