Ezinjinini ezisebenzisayo amasistimu wokujova uphethiloli, kunezigaba ezahlukahlukene esabela ezicini ezimbalwa ezibalulekile zokwakheka nokusebenza kwayo.
Ukuze uhlukanise umjovo ngamunye, kufanele sicabangele inani lama-injection ohlelweni, yakho indawo, umumo kanye ukuvumelanisa imijovo, kanye uhlelo olushayelayo ngamunye wabo.
Amasistimu omjovo ngokuya ngenani labajova
Okokuqala, ngokwesigaba sokuqala, yilapho-ke izinhlelo ze i-multipoint noma umjovo wephuzu elilodwa.
- Mayelana nezinhlelo iphuzu elilodwa, njengoba igama layo libonakala libonisa, sithola umjovo owodwa kuphela, ohlala kuwo indima efana naleyo edlalwa ama-carburettors ezinjinini ezindala.
- Uhlelo amaphuzu amaningi, ngakolunye uhlangothi, isebenzisa i-injector eyodwa kusilinda ngasinye senjini, bese kuba nenani lama-injector ngokulingana ngqo nenani lamasilinda.
Amasistimu wokujova ngokuya ngendawo
Njengoba sishilo ekuqaleni, kunemibandela yokuhlukanisa ngokwezigaba indawo yomjovo, ngakho-ke indawo lapho ingxube kaphethiloli nomoya kwenzeka khona. Okuthile okuzimele enanini lama-injection asetshenzisiwe (ukuhlukaniswa esikuthuthukise endaweni edlule).
Kulesi sigaba, kufanele sisho izinhlobo ezimbili zezindawo, ngaphansi kwegama elithi ngqo noma ngokungaqondile.
- Ku umjovo oqondile, ama-injection ahambisa uphethiloli ngqo ekamelweni elivuthayo. Lolu uhlelo olusetshenziswa iminyaka eminingi ezinjinini zikadizili (isibonelo, I-UIS ne-UPS) futhi esesabalale kakhulu ezinjinini zikaphethiloli, kusukela ekubukeni kwayo ekukhiqizeni izinjini zikaphethiloli nge I-Mitsubishi GDI. Lokhu kungenxa yokuthi izinkinga ezindala ezabangela amazinga okushisa aphezulu, ukuthi Baphahlaze uhlelo kaningi..
- La umjovo ongaqondile, ngakolunye uhlangothi, inawo ama-injection ku ngena ngokuphindaphindiwe noma uma kunesidingo ekamelweni elijikelezayo. Yilapho ihlangana khona nomoya ukuze ifinyelele amagumbi omlilo isatshalaliswe kahle, uma iminyango isivulwe ama-valve wokungena.
Uma ufuna ukwazi okwengeziwe ngalezi zinhlelo zokujova ezimbili, sincoma ukuthi uvakashele i-athikili mayelana nazo umehluko oyisisekelo. Zombili zinenani lezinzuzo nezinkinga ezizenza zifaneleke ngokwehlukile izinhlobo zezinjini.
Izinjini ezihlanganisa umjovo oqondile nongaqondile
Njengoba uhlelo ngalunye lusebenza kangcono kunolunye ezimweni ezithile, kukhona amabhrendi azama ukwenza kanjalo veza okuhle kuyo yomibili imihlaba. Kukhona amamodeli, njengeFord Mustang GT noma i-Audis enenjini engu-2.5 TFSI, esebenzisa uhlelo lomjovo okabili eziqondile nezingaqondile.
Basebenzisa i umjovo oqondile al ukuqala nangaphansi kokusheshisa okukhulu, ngoba kuyisimiso esenza kube lula ukuthungela nokunciphisa ingozi yokuziqhumisa uma uphethiloli omningi ujovwa emakamelweni avuthayo. Kunalokho, lapho ushayela at throttle peak noma ukusheshisa ukukhanya, khetha i umjovo ongaqondile ngoba kukhishwa amagesi angcolisayo amancane, njengoba uphethiloli uhlangana kangcono nomoya.
Amasistimu womjovo oqhubekayo kanye nezikhawu
Lo mehluko usengenziwa, nakuba okusabalele kakhulu ngezizathu zokonga uphethiloli kuyilokhu kwezikhawu.
- umjovo oqhubekayo: umjovo awuphazamiseki, nakuba inani likaphethiloli elidingekayo noma kunini lingahluka. Yayisetshenziswa ezinjini zokujova ezingaqondile, ngoba lolu hlelo aluhambisani nomjovo oqondile.
- umjovo wezikhawu: the Iyunithi yokulawula injini (ECU) Iyakwazi ukulawula ukunikezwa kukaphethiloli okunikezwa ama-injection. Ngale ndlela ungawunqamula umjovo ngokuphelele futhi uwenze usebenze kuphela lapho kudingeka.
Amasistimu womjovo ngokuya ngesikhathi sawo
Ekugcineni, kufanele sithuthukise ukuhlukaniswa ngokwesikhathi somjovo. Ezinhlelweni ze umjovo wezikhawu, umjovo kaphethiloli ungahlanganiswa ngezindlela ezahlukene: kanyekanye, ngokulandelanayo kanye ne-semi-sequential. Ngayinye inomsebenzi ohlukile.
- Umjovo kanyekanye: Uphethiloli ujovwa ngesikhathi esifanayo kuwo wonke ama-injection, aqala noma amise awo ukusebenza ngokubambisana uma iyunithi emaphakathi ikudinga.
- emjovweni ngokulandelana, umjovo uvumelaniswa nokuvulwa kwe-valve yokungena, nakuba i-injector ngayinye ukwenza ngezikhathi ezahlukene.
- emjovweni i-semi-sequential, ama-injection akhipha amafutha ngamabili.
Isistimu yomjovo wemishini noma we-elekthronikhi
Nalapha futhi kukhona ukuhlukaniswa kwezinhlelo zokujova nakuba eyodwa yazo isibekwe ngokuphelele.
- umjovo wemishini: Kuwuhlelo olungasasebenzi olwasetshenziswa emashumini eminyaka okuqala okusetshenziswa komjovo. Ngawo-40, i-electronics yezimoto zanamuhla yayingekho, ngakho-ke umjovo wasebenza ngumsabalalisi wemishini owasabalalisa uphethiloli kumjovo ngamunye. Inani likaphethiloli linqunywe yi- imitha yokugeleza.
- Umjovo we-elekthronikhi: Ukwethulwa kwama-electronics ngawo-60 kwavumela ukulawula okunembe kakhulu nokusebenza kahle kohlelo lomjovo. Isibonelo esihle injini oyibona esithombeni esingenhla ngokushesha: iChevrolet Corvette Sting Ray Fuel Injection yango-1965. Eminyakeni edlule iye yenziwa iphelele, kwaze kwatholakala imiphumela yamanje. Namuhla, i-ECU ithola ulwazi kuzinzwa zezinjini eziningi futhi inquma ngokunembe kakhulu ukuthi izowunikeza nini uphethiloli nokuthi malini.
Isibonelo, uhlelo lomjovo electronics ikuvumela ukuthi ulawule amadigri we ukuthungela phambili, ngenxa yokuthi ithola ulwazi lokushisa, ingcindezi, izinga lomoya, isivinini senjini, njll. Futhi kwenza kube nokwenzeka ukugwema imiphumela eyingozi injini, ezifana ukuzithungela, ukuqhunyiswa nokungqongqoza kwe-crank, noma ufake isicelo a ukusika umjovo uma kwenzeka ingozi.
Ulwazi olwengeziwe mayelana nale modeli
- Amaplaza 4
- Potencia 450 - 460 hp
- Ukusetshenziswa 8,9 - 12l/100km
- Ukuhlola 4,7
Ngifuna ningichazele ukuthi ama-lifters ayini futhi kufanele alungiswe noma ashintshwe nini. Ngoba injini yemoto yami inomsindo omkhulu futhi lokhu kubangelwa umnyusi. Lokhu ngikutshelwe esitolo sokukhanda izimoto.
sawubona kusihlwa ngineMitsubishi pajero 3.5 gdi yaseJapan idlula u-1999 futhi nginenkinga ngoba ibangela umsindo kwesinye isikhathi hhayi njalo uma ngiyivula ngomsindo omkhulu othi emva kwesikhashana ima kungabibikho nowodwa umsindo kube sengathi i-bearing or something like that angiyazi kahle and the other thing is I can't locate the fuel filters zitholakala kuphi??? ithatha amangaki??? njengoba ngiqonda ukuthi i-gdi ethile inokufika koku-3 ngicela usize futhi ngingazitholaphi izingxenye ezisele zale modeli njengoba e-Chile kunzima ukuyithola
Sanibonani, nginemoto yohlobo lweMitsubishi, yadedelwa ngeGDI, ngasebenzisa uphethiloli we-97, angibanga nankinga kwaze kwaba umpompi wenza uphethiloli ongu-90, inani lamasoli ayi-10, yaqala lapho inkinga yami, imoto yayingaqali, yayiqala yaze yaqala yaqala ukufeyila isheke liyajika and is only starter ayivuli kungaba yini isizathu ungangisiza ngingabonga
Badle ingxenye yokuqala yezinhlelo zokujova ngokuya kwesikhathi sokujova kubonakala kimi
Sawubona, ngingumfundi wezobukhenikha bezimoto, lolu lwazi lungisizile ukuhambisana nolwazi lwami, ngisanda kuba nokuhlola okuhlobene namasistimu omjovo kaphethiloli nodizili, ngibonga kakhulu ngala makhasi abelana ngolwazi ngalokhu okuqukethwe,
I-gracias.
incazelo enhle, ngiyabonga.
