Ingabe ukuqala injini kuyinkinga enkulu? Indlela yokuvimbela i-diesel overclocking?
Okuqukethwe
Isebenza kanjani injini kadizili futhi ihlelwa kanjani?
Ukuze uqonde ukuthi ingakanani inkinga yokusheshisa idizili, kufanelekile ukwazi kusengaphambili mayelana nesakhiwo sayo kanye nesimiso sokusebenza. I-diesel drive yathuthukiswa engxenyeni yokuqala yekhulu lama-260, imoto yokuqala eyamukela kwakuyi-Mercedes-Benz XNUMX D. Njengamanje, izixazululo zenjini ezinjalo ziqukethe izakhi eziningi, okuhlanganisa i-flywheel kanye ne-dual-mass flywheel. , ama-camshaft. kanye nama-crankshafts, ama-nozzles, kanye nenduku yokuxhuma noma isihlungi somoya kanye negiya elibuyela emuva.
Izinjini zesimanje zikadizili
Izinjini zesimanje zikadizili zilawulwa izinhlelo zikagesi ezengeziwe. Lokhu kukuvumela ukuthi unikeze ngokunembile umthamo othile kaphethiloli endaweni yenjini. Ngesikhathi esifanayo, ikuvumela ukuba wenze izinguquko eziningi ezithuthukisa ukusebenza kwemoto, kodwa futhi zingaba nomthelela ekunciphiseni impilo yeyunithi yamandla. Abuye ahlome ngezisombululo ezisiza ukunciphisa ukukhishwa kwezinhlanganisela eziguquguqukayo emkhathini. Ngenxa yalokho, bangahlangabezana nezindinganiso eziqinile zezemvelo nezemvelo.
Ukusebenza okujwayelekile kwezinjini zikadizili kuhlotshaniswa nezimo ezithize ezihlukile kunasezindabeni zamayunithi kaphethiloli. Idizayini ayidingi ukusetshenziswa kwama-spark plug ukuze kuqale ukuthungela ingxube yesibaseli somoya. Umoya osesilinda uyacindezelwa bese ushiselwa ezingeni lokushisa elifinyelela ku-900oC. Ngenxa yalokho, ingxube iyathungela futhi ngaleyo ndlela uphethiloli wedizili ujovwe egunjini elivuthayo.
Kuyini ukusheshisa kukadizili?
Imisindo enomsindo nengemnandi evela ngaphansi kwenjini, kanye nentuthu ewugqinsi ephuma ngaphansi kwesivalo kanye nepayipi lokukhipha umoya, izimpawu eziyinhloko zokusheshisa kukadizili. Kulokhu, idrayivu ifinyelela ekuguqukeni okuphezulu kakhulu futhi ayikwazi ukumiswa ize yonakaliswe ngokuphelele. Lapho eqala injini ye-diesel, umshayeli akakwazi ukulawula ukuhamba komcimbi futhi kufanele ashiye imoto ngokushesha futhi abuyele endaweni ephephile. Ukusha okuzenzakalelayo ebangeni eliseduze kungaholela ekulimaleni okukhulu komzimba.
Yini eyenza injini kadizili ime?
Lesi simo ngokuvamile sivela ngenxa yokungena kwamafutha enjini endaweni evuthayo. Esinye sezimbangela ezivame kakhulu zokweqisa kwenjini ye-diesel ukuguga ngokweqile ku-turbocharger. Khona-ke izigxivizo zamafutha azenzi umsebenzi wazo futhi zidlulisa i-lubricant ku-manifold yokuthatha. Uma ixutshwa nophethiloli, udizili uqala ukusebenza. Imiphumela ivame ukuba mibi, futhi ukulungiswa kabusha okukhulu, futhi ngokuvamile ukushintshwa kweyunithi yokushayela, kuyadingeka. Ngokuvamile lokhu akuzuzisi, bese isixazululo kuphela ukulahla imoto.
Yini okufanele uyenze uma uqaphela ukuthi injini ye-diesel igcwele ngokweqile?
Isikhathi somcimbi singathatha ukusuka kumasekhondi ambalwa ukuya kumaminithi ambalwa. Okuwukuphela kwesixazululo ukumisa imoto ngokushesha, bese ushintsha igiya eliphezulu futhi ukhulule i-clutch ngokushesha. Yiqiniso, asikho isiqinisekiso sokuthi lokhu kuzovimbela ukuphunyuka kukadizili. Ngesikhathi esifanayo, singalimaza ezinye izingxenye, kuhlanganise ne-dual mass flywheel.
Injini eshisiwe emshinini wokuthengisa
Ezimotweni ezishintshayo, okuwukuphela kwekhambi ongalizama ukususa ukhiye ekuthuseni.
Iyini imiphumela yokuqalisa injini kadizili?
Kumele ukhumbule ukuthi imiphumela yokuqalisa injini ye-diesel iyinkimbinkimbi kakhulu, futhi umphumela ungaba umonakalo ongenakulungiseka. Lokhu kufaka phakathi, phakathi kokunye:
- ukuqhuma kweyunithi yamandla, imbangela yalokho ukuntuleka kwamafutha enjini;
- ukuqhuma kwalo lonke uhlelo. Ukubhujiswa kwama-bushings kunomthelela ekuqhumeni, ngenxa yalokho induku yokuxhuma ikhishwa ku-cylinder block.
Injini ye-diesel engaphethwe kanye nesihlungi se-diesel particulate (DPF).
Izihlungi ze-VOC zibangela ukwanda kwenani lamafutha ku-sump, okubangela ukuthi ixubane nophethiloli. Njengomphumela walo mshini, ingxube ye-fuel-lubricant ingamuncwa kuyunithi yokushayela. Umphumela wazo zonke izigigaba okukhulunywe ngazo ekungeneni kwanamuhla ungaba umonakalo ongenakulungiseka enjinini kadizili.
Kungenzeka yini ukuvimbela injini overclocking?
Abashayeli bezimoto abaningi bayazibuza ukuthi kungenzeka yini ukuvimbela ukushesha kukadizili nganoma iyiphi indlela. Ngeshwa, ngezinye izikhathi ngisho nezimoto ezisebenza kahle zingahluleka kanje. Ukuze unciphise amathuba okuqalisa injini yakho, shintsha uwoyela wenjini yakho njalo (ngokwezincomo zomkhiqizi noma kaningi) futhi wenze imoto yakho inikezwe isevisi njalo umakhenikha othembekile. Ukutholwa kwamaphutha ngokushesha kuzonciphisa ingozi yokwehluleka.
Noma ngabe ungumnikazi wemoto kaphethiloli noma ekadizili, kufanele wazi ukuthi kuyini ukusheshisa kwenjini kadizili. Ngeshwa, lokhu kuvamile futhi inkinga ivame ukwenzeka ezimotweni ezindala ezisetshenzisiwe. Phakathi kwalezi zinhlobo kukhona iRenault 1.9 dCi, Fiat 1.3 Multijet neMazda 2.0 MZR-CD designs. Gcina lokhu engqondweni lapho unquma ukuthenga imoto eke yasetshenziswa.
