I-exhaust manifold ixhunywe ku-cylinder block yenjini, futhi iqoqa i-exhaust ye-cylinder ngayinye futhi iyiqondise epayipini elikhipha umoya elinamapayipi ahlukene. Imfuneko eyinhloko yalo ukunciphisa ukumelana nokukhipha futhi ugweme ukuphazanyiswa phakathi kwamasilinda. Lapho i-exhaust igxile kakhulu, kuzoba nokuphazamiseka okuhlangene phakathi kwamasilinda, okungukuthi, lapho isilinda siphela, sivele sishaye igesi yokukhipha engazange iphele ngokuphelele kwamanye amasilinda. Ngale ndlela, ukumelana khipha kuzokhula, ngaleyo ndlela kuncishiswe amandla okukhipha injini. Isixazululo sale nkinga ukuhlukanisa ukuphuma kwe-cylinder ngayinye ngangokunokwenzeka, negatsha elilodwa le-cylinder ngayinye, noma igatsha elilodwa lamasilinda amabili, futhi wenze igatsha ngalinye libe lide ngangokunokwenzeka futhi libunjwe ngokuzimela ukuze kuncishiswe ithonya elihlangene lamagesi. emapayipini ahlukene.
Uxhaxha lwegesi ephumayo kufanele lucabangele ukusebenza kwamandla enjini, ukusebenza komnotho kuphethiloli wenjini, izindinganiso zokukhipha umoya, izindleko zenjini, ukumadanisa kwekhabethe langaphambili lemoto kanye nenkundla yezinga lokushisa, njll. Ama-nifold exhaust avame ukusetshenziswa ezinjinini njengamanje ahlukaniswe abe ama-multifold iron iron and. insimbi engagqwali manifolds ngokwezinto zokwakha. Kusukela enqubweni yokukhiqiza, i-exhaust manifold ibonakala ngokusakazwa inqubo, ikakhulukazi ngeukukhishwa kwe-wax elahlekilengenxa yesakhiwo sabo esiyinkimbinkimbi.
Izidingo zama-nifold exhaust
1. Ukumelana okuhle kwe-oxidation ephezulu lokushisa
I-exhaust manifold isebenza ngaphansi kokushintshwa komjikelezo wezinga lokushisa eliphezulu isikhathi eside. Ukumelana ne-oxidation yezinto ezingaphansi kokushisa okuphezulu kuthinta ngqo impilo yesevisi ye-manifold exhaust. Insimbi evamile yokusansimbi ngokusobala ayikwazi ukuhlangabezana nezidingo, futhi izakhi ze-alloy zidinga ukungezwa kundaba ukuze kuthuthukiswe ukumelana ne-oxidation ephezulu yezinga lokushisa.
2. Isakhiwo esincane esizinzile
Ebangeni elisuka kumazinga okushisa ekamelo ukuya kwezinga lokushisa lokusebenza, okokusebenza akufanele kushintshe isigaba noma kuncishiswe ukuguqulwa kwesigaba ngangokunokwenzeka. Ngoba ukuguqulwa kwesigaba kuzodala izinguquko zevolumu, ukucindezeleka kwangaphakathi noma ukuguqulwa, okuthinta ukusebenza nokuphila komkhiqizo. Ngakho-ke, impahla ye-matrix kungcono i-ferrite ezinzile noma isakhiwo se-austenite. Indlela yokubhubhisa yezingxenye zensimbi ezisebenza ngaphansi kwezimo eziphakeme zokushisa ibonakala ngokuyinhloko njengokugqwala ngaphansi kwezimo zokushisa eziphezulu. Ngemuva kokuthi izigaba ezikhona enhlanganweni sezifakwe i-oxid (njenge-graphite carbon), umthamo we-oxide mkhulu kunevolumu yasekuqaleni, okubangela ukunwebeka okungenakuhlehliswa kokusakazwa. Uma kuqhathaniswa nezinhlobo ezintathu ze-graphite ze-flake, i-worm kanye ne-spherical, i-cast iron ene-spherical graphite inokumelana okungcono kakhulu kwezinga lokushisa. Isizathu siwukuthi phakathi nenqubo yokuqinisa insimbi eyinsimbi, i-flake graphite ikhula njengesigaba esiholayo. Ekupheleni kokuqina kwe-eutectic, i-graphite eqenjini ngalinye le-eutectic yakha ifomu eliqhubekayo le-branched-dimensional. Emazingeni okushisa aphezulu, lapho umoya-mpilo uhlasela insimbi, i-graphite ikhishwa i-oxidized ukuze yakhe umzila we-microscopic, osheshisa inqubo ye-oxidation. Lapho i-graphite eyindilinga iyindilinga, ikhula ibe usayizi othile iyodwa futhi izungezwe i-matrix. Ikhona njengebhola elingalodwa. Ngemuva kokuthi ibhola le-graphite lifakwe i-oxidized, akukho siteshi esakhiwayo, ngaleyo ndlela senza buthaka i-oxidation eyengeziwe. Ngakho-ke, ukumelana nokushisa okuphezulu kwe-oxidation yensimbi ye-ductile kungcono kunezinye izinhlobo ze-graphite, futhi izimbobo ezine-oxidized zinomthelela omncane emandleni okushisa aphezulu ensimbi ephonsiwe kunezinye izinhlobo ze-graphite. I-Vermicular graphite iphakathi kwalokhu okubili.
3. I-coefficient encane yokwandisa ukushisa
I-coefficient encane yokunwetshwa kwe-thermal isiza ekwehliseni ingcindezi yokushisa kanye nokuguquka kokushisa kwe-exhaust eninginingi, futhi isiza ekuthuthukiseni ukusebenza nempilo yesevisi yomkhiqizo.
4. Amandla okushisa aphezulu kakhulu
Kufanele ihlangabezane nezidingo zamandla ezidingekayo zomkhiqizo lapho isetshenziswa emazingeni okushisa aphezulu.
5. Ukusebenza kahle kwenqubo kanye nezindleko eziphansi
Kunezinhlobo eziningi zezinto zensimbi ezikwazi ukumelana nokushisa nezingashisi kakhulu, kodwa ngenxa yesimo esiyinkimbinkimbi se-exhaust manifold, izinto ezisetshenziselwa ukukhiqiza i-exhaust manifold kufanele zibe nokusebenza okuhle kwenqubo, futhi izindleko zayo kufanele zihlangabezane nezidingo zesisindo. ukukhiqizwa embonini yezimoto.
