Ipayipi le-exhaust muffler liyingxenye yesistimu yokukhipha injini.Uhlelo lwepayipi le-exhaust muffler ikakhulukazi lihlanganisa i-exhaust manifold, ipayipi yokukhipha kanye ne-muffler.Ngokuvamile, i-catalyst emithathu yokulinganisa ukulawula ukukhishwa kwezinto ezingcolile zenjini nayo ifakwe ohlelweni lwe-exhaust.Ipayipi lokukhipha i-exhaust ngokuvamile lihlanganisa ipayipi yokukhipha ngaphambili kanye nepayipi yokukhipha ngemuva.

Ngemva kokuba umoya ohlanzekile nophethiloli kuxutshwe enjinini ukuze kushiswe, izinga lokushisa eliphezulu kanye namagesi anengcindezi ephezulu kukhiqizwa ukuphusha ipiston.Lapho amandla egesi ekhishwa, asuke engasabalulekile enjinini.Lawa magesi aba amagesi akhipha umoya futhi akhishwa enjinini.Ngemuva kokukhipha isilinda, igesi yokukhipha ingena exhaust manifold.Ngemuva kokuqoqwa kwe-multifold exhaust ye-cylinder ngayinye, igesi yokukhipha ikhishwa ngepayipi yokukhipha.

Njengoba imithetho yokuvikela indawo ezungezile iqine kakhulu ezimisweni zokuphuma kwezimoto, akukhathaleki ukuthi ungenzi lutho, uyashesha, ukushayela ngesivinini esiphansi, ukushayela ngesivinini esiphezulu noma ukwehlisa isivinini, zonke izimoto kufanele zihlangabezane nezindinganiso zokukhipha umoya.Ngokubhekana nemikhawulo enjalo eqinile, ngaphezu kokuzuza ibhalansi phakathi kokusebenza nokukhipha, into kuphela i-catalytic converter.Isiguquli se-catalytic ngokuvamile senziwe ngezinsimbi eziyigugu, okuhlanganisa i-oxidation catalyst, i-catalyst yokunciphisa kanye nesiguquli se-catalytic sezindlela ezintathu esisetshenziswa ezimotweni eziningi.Ngemuva kokukhipha amandla amaningi, isiguquli se-catalytic sixhunywa ukuze kuguqulwe ukungcola okungashiswa ngokuphelele kube izinto ezingenabungozi ukuze kuvikelwe imvelo.

Ixhunywe ku-muffler kusuka kusiguquli se-catalytic.Ingxenye yesiphambano se-muffler yinto eyindilinga noma eyi-oval, ehlanganiswe ngamapuleti ensimbi amancane futhi afakwe phakathi noma ngemuva kwesistimu yokukhipha umoya.Kukhona uchungechunge lwama-baffles, amagumbi, ama-orifices namapayipi ngaphakathi kwe-muffler.Ukwenzeka kokuphazanyiswa kwe-acoustic reflection kanye nokukhansela kusetshenziselwa ukwenza kancane kancane amandla omsindo kube buthaka, ukuze kuhlukaniswe futhi kuncishiswe umfutho oshaya ngamandla okhiqizwa isikhathi ngasinye lapho kuvulwa i-valve yokukhipha umoya.
