【摘要】 依据热工理论和声学原理，研制了一种公路客车用排气换热消声器。它在取代汽车原消声器的同时，可实现换热和消声的双重目的。实验结果表明，该装置回收排气余热量大，和原消声器相比，排气阻力较小，降噪效果明显。更多还原

【Abstract】 On the basis of thermodynamic theory and acoustic principle, a kind of exhaust heat exchange muffler for a road bus has been developed. The new muffler can achieve double goals of both heat exchange and muffling when the original exhaust muffler of a road bus is replaced with it. The test results show that it can recover much more exhaust heat, and less exhaust resistance and lower noise than the original one.更多还原
