1.引言近年来电子控制技术在小客车上得到广泛的应用,以便满足市场对高性能、高标准的要求. 本文提出了一种新的电子控制技术,该技术通过加装结构简单的改进装置,就能降低排气系统的噪声和压力.该技术意在解决既降低排气噪声,又提高动力性的矛盾要求.它能有效地降低排气系统的低频噪声,低频噪声对乘坐室的轰鸣噪声有很大影响.
1. Introduction In recent years, electronic control technology has been widely used in passenger cars in order to meet the market demand for high performance and high standards.This paper presents a new electronic control technology, the technology through the installation of simple structure improvement device , The noise and pressure of the exhaust system can be reduced.This technology is intended to solve the conflicting requirements of reducing exhaust noise and improving power performance and it can effectively reduce the low frequency noise and the low frequency noise of the exhaust system to the roar of the passenger compartment Noise has a big impact.
