Sezvo mirau yekudzivirira kwezvakatipoteredza yakanyatso kuomarara pamitemo yekuburitsa mota, zvisinei nekusashanda, kukurumidza, kutyaira kwakaderera, kutyaira kwakanyanya kana kudzika, mota dzese dzinofanirwa kuzadzisa zviyero.Pamberi pezvirambidzo zvakaomarara zvakadaro, mukuwedzera pakuwana chiyero pakati pekuita uye kuburitsa, chinhu chega chiri catalytic converter.Iyo catalytic inoshandura inowanzo gadzirwa nesimbi dzakakosha, kusanganisira oxidation catalyst, kuderedza catalyst uye matatu-nzira catalytic converter inoshandiswa mumotokari zhinji.Mushure mekupedza manifold, inoshandura inoshandura inosungirirwa kushandura tsvina isina kupiswa kuita zvinhu zvisingakuvadzi kuchengetedza nharaunda.

Iyo yakabatana kune muffler kubva kune inoshandura inoshandura.Chikamu chemuchinjikwa chemuffler chinhu chakatenderera kana chakavharidzirwa, icho chinosungirirwa nesimbi dzakatetepa mahwendefa uye yakaiswa pakati kana kumashure kweiyo exhaust system.Kune nhevedzano yemabhaffles, chambers, orifices uye mapaipi mukati memuffler.Chiitiko cheacoustic reflection interference nekukanzura chinoshandiswa kuderedza zvishoma nezvishoma simba rekurira, kuitira kuparadzanisa uye kudzikamisa pulsating pressure inogadzirwa pese pavhurwa valve yekuburitsa.
