Iyo manifold exhaust yakabatana neinjini cylinder block, uye inounganidza kubuda kwecylinder yega yega uye inotungamira mupombi huru yekuburitsa ine mapaipi akasiyana. Chinhu chikuru chinodiwa pairi ndechekuderedza kuputika kwekudzivirira uye kudzivisa kupindirana pakati pemasilinda. Kana iyo inopera yakanyanyisa, pachava nekupindirana pakati pemasilinda, kureva, kana silinda inopera, inongorova gasi rinoputika risina kupera zvachose kubva kune mamwe mavhavha. Nenzira iyi, iyo inopokana yekupokana ichawedzera, nekudaro ichidzikisa simba rekubuda reinjini. Mhinduro yedambudziko iri ndeyekuparadzanisa kupera kwecylinder imwe neimwe zvakanyanya sezvinobvira, nebazi rimwe kune rimwe cylinder, kana rimwe bazi remasilinda maviri, uye kuita kuti bazi rimwe nerimwe rive rakareba sezvinobvira uye rakazvimiririra rakaumbwa kuderedza kuwirirana kwemagasi. mumapombi akasiyana.
Iyo manifold echaust inofanirwa kufunga nezvekuita kweinjini simba, kuita kweinjini yemafuta ehupfumi, emission standard, mutengo weinjini, inofananidzwa nemotokari yepamberi kabhini marongero uye tembiricha yemunda, nezvimwewo. Manifolds emhepo anowanzoshandiswa painjini parizvino akakamurwa kuita simbi yakawanda uye Stainless simbi manifolds maererano nezvinhu. Kubva pakuita kwekugadzira, iyo manifold yekuburitsa inoonekwa nekukanda maitiro, kunyanya nekurasika kukanda wakisinekuda kwechimiro chavo chakaoma.
Zvinodikanwa zvekupedza manifolds
1. Yakanaka yakakwirira-tembiricha oxidation kuramba
Iyo manifold exhaust inoshanda pasi pepamusoro-tembiricha cyclic alternation kwenguva yakareba. Iyo oxidation inopikisa yezvinhu pasi pekushisa kwepamusoro inobata zvakananga hupenyu hwebasa reiyo manifold exhaust. Yakajairika simbi yakakandwa zviri pachena haigone kusangana nezvinodiwa, uye alloy zvinhu zvinoda kuwedzerwa kune izvo zvinhu kuti uvandudze yakakwirira-tembiricha oxidation kuramba kwezvinhu.
2. Yakagadzikana microstructure
Mukati kubva kune tembiricha yekamuri kusvika kune tembiricha yekushanda, izvo zvinhu hazvifanirwe kuita shanduko yechikamu kana kuderedza shanduko yechikamu zvakanyanya sezvinobvira. Nekuti shanduko yechikamu ichakonzera kushanduka kwevhoriyamu, kushushikana kwemukati kana deformation, kukanganisa kushanda uye hupenyu hwechigadzirwa. Naizvozvo, iyo matrix zvinhu zviri nani yakagadzikana ferrite kana austenite chimiro. Iyo nzira yekuparadza yezvikamu zvesimbi zvakakandwa zvinoshanda pasi pemamiriro ekushisa akanyanya kuratidzwa sekuora pasi pemamiriro ekushisa kwakanyanya. Mushure mekunge zvikamu zvinoumba musangano zvave ne oxidized (zvakadai se graphite kabhoni), vhoriyamu yeokisidhi yakakura kudarika vhoriyamu yepakutanga, zvichikonzera kuwedzera kusingadzoreki kwekukanda. Kana ichienzaniswa neatatu magirafu mafomu eflake, worm uye spherical, simbi yakakandwa ine spherical graphite ine yakanyanya kunaka kupisa tembiricha. Chikonzero ndechekuti panguva yekusimba kwesimbi yakakandwa, flake graphite inokura sechikamu chinotungamira. Pakupera kweeutectic solidification, iyo graphite muboka rega rega eutectic inoumba inoenderera branched matatu-dimensional fomu. Pakupisa kwepamusoro, apo okisijeni inopinda musimbi, girafu inoiswa oxidized kuti iite microscopic channel, iyo inokurumidzira maitiro ekuita oxidation. Kana spherical graphite nucleates, inokura kusvika kune imwe saizi yega uye yakakomberedzwa nematrix. Iripo sebhora riri roga. Mushure mekunge bhora regirafu rave oxidized, hapana chiteshi chinoumbwa, nokudaro kuderedza kuwedzera oxidation. Naizvozvo, tembiricha yakakwira oxidation kuramba kwe ductile iron iri nani pane yemamwe marudzi egraphite, uye maburi ane oxidized ane mhedzisiro shoma pakusimba kwekushisa kwesimbi yakakandwa pane mamwe marudzi egraphite. Vermicular graphite iri pakati pezviviri.
3. Diki rekuwedzera kwemafuta coefficient
Iyo diki yekupisa yekuwedzera coefficient inobatsira kudzikisira kushushikana kwekupisa uye deformation yekupisa kweiyo manifold ekunze, uye inobatsira kuvandudza mashandiro uye hupenyu hwebasa rechigadzirwa.
4. Excellent high tembiricha simba
Inofanira kusangana nezvinodiwa zvesimba zvinodiwa zvechigadzirwa kana zvichishandiswa pakupisa kwakanyanya.
5. Kuita kwakanaka kwemaitiro uye mutengo wakaderera
Kune akawanda marudzi emhando dzesimbi dzisingadzivirirwe uye dzakakwira-tembiricha dzinodzivirira, asi nekuda kwechimiro chakaomarara cheanopotera manifold, zvinhu zvinoshandiswa kugadzira exhaust manifold zvinofanirwa kuve nekuita kwakanaka kwekuita, uye mutengo wayo unofanirwa kusangana nezvinodiwa zvehuwandu. kugadzirwa muindasitiri yemotokari.
