Kukhona izinhlobo ezahlukene ze-exhaust muffler, ezihlukaniswa ngokwendlela ezikwazi ngayo ukudambisa lowo msindo futhi zikhiphe amagesi aphuma enjinini. Ukuthi ezezimoto, izithuthuthu, izikebhe, njll., zingahlukaniswa zibe: ukumuncwa, ukunwetshwa, i-lateral resonator kanye nokuphazamiseka.
Kodwa-ke, akuwona wonke ama-exhaust silencers emakethe alingana nalolu hlu. Empeleni, abaningi babo basebenzisa izindlela ezimbalwa ngesikhathi esisodwa ukunciphisa umsindo kumafrikhwensi ahlukahlukene. Ngale ndlela, bathola imiphumela engcono kakhulu uma besebenzise eyodwa kuphela.
Sike sakhuluma ngaphambilini mayelana ukusebenza kwe-muffler, ibala kafushane izingxenye zayo ukuze kuncishiswe umsindo ovela lapho amagesi eqala ukuphuma ngobudlova enjinini. Lapha, sizokhuluma nge izinhlobo zokunciphisa umsindo ezikhona zezinhlobo ezahlukene zezimoto.
Isithulisi se-exhaust sokumuncwa
Kuma-absorption silencers, i amashubhu oboya bengilazi, uvolo wamaminerali noma ezinye izinto ezifanayo. Ngaphezu kwalokho, umsindo ungaphoqeleka ukuba udlule emathanjeni amaningana, ahlala embozwe nge-acoustic insulation, ukuze abambe umsindo omkhulu ngangokunokwenzeka.
Kulolu hlelo lokumunca umsindo kuyadingeka ukusebenzisa izinto ezimelana namazinga okushisa nokuhamba kwesikhathi. Noma kunjalo, i ukungathandeki abanakho wukuthi ngokuhamba kwesikhathi bagcine sebewohloka. Uma ifika kulelo qophelo, uvolo wengilazi noma izinto ezisetshenziswayo zingagcina ziphuma epayipini le-exhaust noma zivaleleke ngaphakathi kwe-muffler ngaphandle kokufeza injongo yazo. Kulokhu kufanele ushintshe ukuze uthole entsha.
La inzuzo Olunye lwalolu hlobo lwezithulisi zamapayipi e-exhaust ukuthi zisebenza kanyekanye i-insulator eshisayo ne-acoustic. Ngenxa yalesi sizathu, asetshenziswa kaningi ezithuthuthu, lapho kulula ukuthinta ipayipi yokukhipha ngomlenze wakho. Yiqiniso, asetshenziswa kwezinye izinhlobo zezimoto noma imishini, njengoba ukufakwa kwe-thermal kuyadingeka ezimweni eziningi.
isithulisi sokunweba
Ezithulini zokunweba, a i-tube flare,aphinde awuqinise. Ngenxa yalokhu, kanye ne-geometry yekamelo, ingxenye yalowo msindo ibuyiselwa emthonjeni.
Lolu hlobo lwe-exhaust muffler luwusizo kakhulu emisindweni enamandla agxile kumafrikhwensi ambalwa. Umsebenzi wawo uwukuhlakaza lawo mandla phakathi kwamafrikhwensi amaningi ngangokunokwenzeka ukuze kuzuzwe umsindo oshwaqekayo omncane kakhulu.
La ukungathandeki yalolu hlobo lwezithulisi ukuthi basusa umsindo omncane kakhulu. ISu inzuzo yilokho abayikho kuhlanganiswe kalula nganoma yiziphi ezinye izindlela njengoba kokubili ukunwetshwa nezindlela zokuphazamiseka zidinga umgodi obanzi ukuze usebenze. Ngaphandle kokuqhubeka, isithombe esikulesi sigaba sibonisa izithuli ezisebenzisa izinhlobo ezahlukene. Kodwa bakwenza kucace ukuthi kuyini ukuma kwe-muffler yokwandisa ngaphandle.
Indlela yokwandisa isetshenziswa ezithuthuthu, izimoto namaloli, kodwa ayivamisile ukusetshenziswa iyodwa namuhla ngenxa yokusebenza kahle kwayo okuphansi. Isithulisi esinjalo ngeke siphumelele izidingo ezincane ezibekwe yimithetho ye-acoustic. Kunoma yikuphi, isimiso somzimba abasebenza ngaso sisetshenziselwa ukuguqula imvamisa yomsindo. Ngale ndlela ungathola umsindo ojulile we-exhaust uma ufuna.
Isithulisi se-resonator eseceleni
El i-side resonator exhaust muffler Isebenza ngokubhoboza ipayipi le-exhaust futhi izungezwe ngobubanzi obukhudlwana. Njengoba ubona esithombeni, amashubhu ahlukaniswa ukuze enze umsindo udlule usuka kwelinye uye kwelinye ngokuphindaphindiwe futhi wehlise ivolumu ngokulokhu ubhampa ezindongeni zawo.
La inzuzo abanakho ukuthi bahlangene ngenxa yesimo sabo. Yingakho zivame ukusetshenziswa ezithuthuthu, nakuba zingabonakala nasezimotweni namaloli. Sekushiwo lokho, kufanele kuqashelwe ukuthi le ndlela yokunciphisa umsindo ayisetshenziswanga yodwa ezimotweni ezijwayelekile. I ukungathandeki kunjalo ngokwazo azisizi ngalutho. Ngokuvamile zihlanganiswa nama-acoustic insulators anciphisa umsindo ngenxa yokungqubuzana phakathi kwezinye izinhlelo, amagumbi okunweba noma izithulisi zokuphazanyiswa.
Umphumela uba ukuthi ukusatshalaliswa okuboniswe kulesi sithombe akukona kuphela okukhona kweresonator yangemuva. Ngokwesibonelo, ithubhu elingaphakathi nalo lingasonteka njengethumbu ukungena ku-a igobolondo elingunxande. Kungenzeka futhi ukudala i-silencer enamakamelo amaningana usebenzisa izindlela ezahlukene futhi kwelinye lazo kukhona ishubhu elilodwa le-resonator ohlangothini. Ithimba eliphethe i-muffler lizokhetha ukucushwa okungcono kakhulu kwemoto ngayinye.
isithulisi sokuphazanyiswa
I-exhaust muffler yokuphazamiseka yenza gxuma amaza omsindo ukuze aphazamisane. Ukufeza lokhu, i-cavity igcwele amapuleti ane-perforated kanye nama-parallel. Ngakho bakha ama-echo amancane akhansela kancane amagagasi futhi kancane kancane anciphise umsindo.
Noma kunjalo, kuyinto evamile ukuyihlanganisa nezithulisi zokumunca. Ngale ndlela, ngaphezu kokuzuza ukuphazamiseka, ukunciphisa ngenxa yokungqubuzana nakho kufinyelelwa. Ngaphezu kwalokho, njengoba sike sakutshela ngaphambili, zibuye zihlanganiswe nama-resonator aseceleni, okudala uhlelo lwe-cavity oluyinkimbinkimbi.
Su inzuzo yilokho kuhlanganiswe kalula nezinye izinhlobo zezithulisi. Yabo ukungathandeki ukuthi kungase kudinge isikhala esiningi, ngakho-ke isithulisi sizoba sikhulu kakhulu. Isici esingahambisani nanoma iyiphi imoto.
I-resonator ye-Helmholtz
Lokhu kugxambukela kungazuzwa ngesinye isimunyisi se-acoustic esingasizwanga kangako: i I-resonator ye-Helmholtz. Kuyikamelo umoya walo wangaphakathi osebenza njengodonga lomoya olungabonakali.
Isithombe sibonisa a I-resonator ye-Helmholtz njengoba yakhulelwa, kodwa yayo indlela kuma-exhaust mufflers ijwayelane nezidingo zemoto. Nokho, kuyincazelo enhle yokuthi isebenza kanjani. Ukuze uyiqonde, kufanele nje ukhumbule umphumela wendiza enophephela emhlane okwenzeka lapho wehlisa iwindi emgwaqeni noma emgwaqeni omkhulu. Lokho kudlidliza okungakhululekile emoyeni okulimaza izindlebe zabahlali.
Kuyafana, kodwa i-resonator yakhelwe ngosayizi ofanele, ukujiya kanye nempahla ukukhiqiza ukudlidliza ukhonkolo: yona leyo engena ngomsindo wenjini. Okusho ukuthi, i-resonance yenziwa nge-frequency efanayo eyethulwa kuyo ngakho-ke iyayikhansela.
La inzuzo yalesi muffler exhaust kunjalo icishe ikhansele ngokuphelele imvamisa engena kuyo. ISu ukungathandeki ukuthi, kuye ngezici zayo, Izothinta amanye amafrikhwensi kakhulu hhayi amanye.. Ngakho-ke, imvamisa ilinganiselwe amaza omsindo aphezulu kakhulu akhishwa injini okukhulunywa ngayo. Okusho ukuthi, injini engu-1.2 litre kaphethiloli ngeke ifane neyenjini engu-4.4 litre turbodiesel. Abathuthukisi bemodeli bazoba nomthwalo wemfanelo wokubala. Kuwo wonke amanye ama-frequency, izithulisi zepayipi zokuqeda ezichazwe ngenhla ziyasetshenziswa.
