I-exhaust eningi yezimoto - ukungasebenzi kahle, izimpawu, ukulungiswa kokukhipha okuningi

I-element injini, okuyi-multifold exhaust, ingase ibonakale ilula kakhulu, inezinkinga eziningana. Zincike ekwakhiweni kweyunithi kanye nokungasebenzi kahle okuhlukahlukene kumamodeli emoto ngayinye. Isibonelo, enjinini engu-1.9 TDI yeGolf V, i-exhaust manifold gasket ivamise ukuhlukaniswa ukusuka phezulu kwebhulokhi yesilinda. Emayunithi kaphethiloli amadala we-Opel (2.0 16V), ukuqhekeka kuvele cishe phakathi nendawo. Kungani i-exhaust eningi ingahlali unomphela ezimotweni ezivuthayo?

Kungani i-exhaust eningi ihluleka? Izici ezibalulekile okungenzeka zonakaliswe

Okubaluleke kakhulu ekusebenzeni kwe-exhaust manifold yizimo zokusebenza zesistimu yonke. Ukusebenza kwayo kuthintwa:

• izinga lokushisa;
• vibration kusukela injini;
• izimo zomgwaqo;
• ukusebenza kwemoto.

Ukuthintana nebhulokhi yenjini kubangela ukuthi le elementi ishise ifike kumazinga okushisa aphezulu. Amagesi e-exhaust adlula ku-exhaust afudumele kakhulu (kufika ku-700 degrees Celsius kumayunithi kaphethiloli), okuthinta ukunwetshwa kwezinto. Ngaphezu kwalokho, ukudlidliza okuvela enjinini, ukunwetshwa kokushisa okuguquguqukayo kwezinto ezihlukile (i-aluminium iziphatha ngendlela ehlukile kunensimbi ekhonjiwe), ithonya lokushintsha izimo zangaphandle (iqhwa, udaka, amanzi) futhi, ekugcineni, indlela imoto esebenza ngayo kufanele futhi yengezwe. . . Ngakho-ke, umqoqi wezimoto ujwayele ukungasebenzi kahle kuzo zonke izinhlangothi. Yini evame ukungalungile kuye?

I-exhaust eningi eqhekekile - kungani lokhu kwenzeka?

Ithonya elikhulu kukho umqoqi wemoto amakhefu, ahlangane nezinto ezingafani. I-cast iron, okwenziwa ngayo i-exhaust eningi ngokuvamile, ifudumala kancane kune-aluminium nensimbi. Ngakho-ke, ikakhulukazi lapho ushayela kakhulu injini ebandayo, kungenzeka ukuthi i-aluminium block iziphatha ngendlela ehlukile kune-cast iron manifold. Izikhonkwane zensimbi eziphumayo eziningi zibambelela kahle ekubambeni, okungenjalo kumanifold ashiselwe. Ngenxa yalokho, isici siphuka, njengomthetho, endaweni yokushisela.

I-multiple exhaust eqhekekile iwuphawu lokuwohloka nokwehluleka. Kudingeka nini ukushintshwa noma ukulungiswa?

Indlela elula yokubona inqwaba eqhekekile ukuqala injini. Umsindo wokusebenza kwayo uhlukile, kanti kwezinye izimoto ijika ishintshashintsha ngokuya nge-rpm ephansi noma ephezulu kanye nezinga lokufudumala kwenjini. Ukusebenza okuthambile kwangaphambilini kweyunithi kanye nokuthula okujabulisayo ekhabetheni kuphenduka umsindo wensimbi ocasulayo. Nokho, ngeke kwenzeke ngaso sonke isikhathi ukubona lapho konakala khona i-exhaust manifold. Ngokuvamile isizathu siyi-microcracks, engabonakali ngaphandle kwe-disassembly nokuhlolwa etafuleni.

I-Exhaust manifold welding - ingabe kufanelekile?

Uma ubuza noma yimuphi "umuntu onolwazi" ahlangana naye, uzokutshela ukuthi kungenziwa. Futhi ngokomthetho uzobe elungile, ngoba umqoqi ovuzayo angenziwa ukwenziwa. Nokho, umphumela wesenzo esinjalo awubi njalo (empeleni kaningi) mubi. Lokhu kungenxa yokuthi i-cast iron iyinto edingeka kakhulu ekucutshungulweni. Kushibhile futhi kuhlala isikhathi eside, kodwa ukushisela kudinga amasu afanele.

Ukukhipha i-multifold replacement noma i-welding?

Phakathi nale nqubo, i-brittleness yempahla ye-welds ibonakala, engabonakala lapho ipholile. Uma kuvela ukuthi konke sekuphekwe kahle, ngokuzumayo uzozwa "pop" futhi yonke imisebenzi yakho iyize. Ngaphezu kwalokho, lapho i-welding, umqoqi wehlisa ukugeleza kwayo, okuthinta kabi ukusebenza kweyunithi. Ukulungiswa kwesikhathi esisodwa ngale ndlela kuyamukeleka, kodwa kungcono kakhulu ukuthenga ingxenye yesibili esitolo se-intanethi (ngisho nesisetshenzisiwe), ngoba intengo cishe izofana.

Kuthiwani ngokususa i-exhaust manifold?

Nakuba i-exhaust manifold iyipayipi lensimbi elishiselwe efekthri, inomthelela omkhulu kakhulu ekusebenzeni kwenjini. Ubude bomqoqi ngokwawo buthinta kakhulu ukusebenza, njengoba kwenza iphrofayili yeziteshi. Uma ubheka le mininingwane, uzoqaphela ukuthi ngesinye isikhathi ihlangana ibe yipayipi elilodwa elidlula ikhebula elingaphansi kwenjini. I-lambda probe ivamise ukufakwa kusilinda ukuze kukale ikhwalithi yegesi yokukhipha umoya.

Amashuni, nawo, azimisele kakhulu ukuguqula yonke isistimu yokukhipha umoya, eqala ngenqwaba, enomthelela omkhulu ekuzuzeni amandla kububanzi obuhlukahlukene be-rpm (ikakhulukazi ephezulu). Kulokhu singaphetha ngokuthi umqoqi akanakulahlwa.

Yini okufanele uyenze uma kunenkinga ngobuningi bokudla? Izimpawu ngezinye izikhathi azibonakali ngeso lenyama, ngakho-ke kufanelekile ukuthintana nochwepheshe. I-manifold eyonakele emotweni ayifanele neze ukukhanda, ngakho-ke kungcono uma unquma ukuthenga ingxenye entsha imoto engakwazi ukuyenza ngaphandle kwayo.
