Isistimu kaphethiloli yemoto

Ayikho imoto enenjini yomlilo yangaphakathi ngaphansi kwe-hood ezoshayela uma ithangi lalo likaphethiloli lingenalutho. Kepha hhayi kuphela uphethiloli okuleli thangi. Isadinga ukulethwa kumasilinda. Ukuze wenze lokhu, uhlelo lwamafutha lwenjini lwakhiwe. Ake sicabangele ukuthi unemisebenzi enjani, nokuthi imoto yeyunithi kaphethiloli ihluke kanjani kunhlobo esebenza ngayo injini kadizili. Ake sibheke nokuthi yiziphi izinto ezenzekayo zesimanje ezandisa ukusebenza kahle kokunikezela nokuxuba uphethiloli nomoya.

Luyini uhlelo lwamafutha lwenjini

Uhlelo lukaphethiloli luyimishini evumela ukuthi injini isebenze ngokuzimela ngenxa yomlilo wenhlanganisela yomoya-petrol ocindezelwe kumasilinda. Ngokuya ngemodeli yemoto, uhlobo lwenjini nezinye izinto, uhlelo olulodwa lukaphethiloli lungahluka kakhulu kolunye, kepha zonke zinomgomo ofanayo wokusebenza: zinikeza uphethiloli ezinhlakeni ezihambisanayo, zixube nomoya futhi ziqinisekise ukutholakala okungaphazanyiswa kwe ingxube kumasilinda.

Uhlelo lokuphakelwa kukaphethiloli ngokwalo aluhlinzeki ngokusebenza okuzimele kweyunithi yamandla, kungakhathalekile ukuthi hlobo luni. Kuqondaniswe nohlelo lokushisa. Imoto ingafakwa okunye kokuguqulwa okuningana okuqinisekisa ukuthungela ngesikhathi kweVTS. Imininingwane ngezinhlobonhlobo kanye nenqubo yokusebenza kwe-SZ emotweni ichaziwe kokunye ukubuyekeza... Uhlelo lusebenza futhi ngokubambisana nohlelo lokungenisa lwenjini yomlilo yangaphakathi, echazwe ngokuningiliziwe. lapha.

Yiqiniso, umsebenzi oshiwo ngenhla wemoto uthinta amayunithi kaphethiloli. Injini kadizili isebenza ngendlela ehlukile. Ngamafuphi, ayinayo uhlelo lokushisa. Uphethiloli kadizili uyasha kwisilinda ngenxa yomoya oshisayo ngenxa yokucindezela okuphezulu. Lapho ipiston iqeda ukushaywa unhlangothi, ingxenye yomoya oyisilinda iyashisa kakhulu. Okwamanje, kufakwa uphethiloli kadizili, bese i-BTC ikhanya.

Inhloso yohlelo lwamafutha

Noma iyiphi injini evutha i-VTS ifakwe imoto, izakhi ezahlukahlukene zayo ezihlinzeka ngezenzo ezilandelayo emotweni:

1. Nikeza ngokugcinwa kukaphethiloli ethangini elihlukile;
2. Kuthatha uphethiloli ethangini likaphethiloli;
3. Ukuhlanza imvelo ngezinhlayiya zangaphandle;
4. Ukunikezwa kwamafutha kuyunithi lapho kuxutshwe khona nomoya;
5. Ukufafaza i-VTS kwisilinda esisebenzayo;
6. Ukubuya kwe-Fuel uma kwenzeka ngokweqile.

Imoto yakhelwe ngendlela yokuthi ingxube evuthayo inikezwe isilinda esisebenzayo ngesikhathi lapho umlilo we-VTS uzosebenza kahle kakhulu, futhi ukusebenza kahle okuphezulu kuzosuswa emotweni. Njengoba imodi ngayinye yenjini idinga umzuzu ohlukile nezinga lokuphakelwa kukaphethiloli, onjiniyela benze izindlela ezijwayela ijubane lenjini nomthwalo wayo.

Idivayisi yesistimu ye-Fuel

Iningi lezinhlelo zokulethwa kukaphethiloli zinohlelo olufanayo. Ngokuyinhloko, uhlelo lwe-classic luzoqukatha izinto ezilandelayo:

• Uphethiloli noma ithangi. Igcina uphethiloli. Izimoto zesimanje zithola okungaphezu nje kwesitsha sensimbi esilingana nomgwaqo omkhulu. Inomshini ocishe ube yinkimbinkimbi onezinto eziningana eziqinisekisa ukugcinwa kahle kwephethiloli noma kukaphethiloli. Lolu hlelo lubandakanya isikhangiso, isihlungi, inzwa yezinga futhi kumamodeli amaningi ipompo ezenzakalelayo.
• Ulayini kaphethiloli. Ngokuvamile lokhu kuyipayipi lenjoloba eliguquguqukayo elixhuma iphampu kaphethiloli nezinye izinto ezisohlelweni. Emishinini eminingi, amapayipi ayashintshashintsha ngokwengxenye futhi aqinile (le ngxenye inamapayipi wensimbi). Ishubhu elithambile lakha ulayini kaphethiloli onengcindezi ephansi. Engxenyeni yensimbi yomugqa, uphethiloli noma uphethiloli unengcindezi enkulu. Futhi, ulayini kaphethiloli wezimoto ungahlukaniswa ngemibandela izifunda ezimbili. Owokuqala unesibopho sokondla injini ngengxenye entsha kaphethiloli, futhi ubizwa ngokuthi yi-supply. Esifundeni sesibili (ukubuya), uhlelo luzokhipha uphethiloli / udizili owedlulele ubuyele ethangini legesi. Ngaphezu kwalokho, umklamo onjalo ungabi kuphela ezimotweni zesimanje, kepha nakulabo abanohlobo lwe-carburetor lokulungiselela i-VTS.
• Ipompo kaphethiloli. Inhloso yale divayisi ukuqinisekisa ukupompa okuqhubekayo kwento yokusebenza kusuka echibini kuya kwizifutho noma egumbini lapho i-VTS ilungiswa khona. Ngokuya ngohlobo luni lwemoto olufakiwe emotweni, le ndlela ingaqhutshwa ngogesi noma ngemishini. Iphampu kagesi ilawulwa yiyunithi yokulawula ngogesi, futhi iyingxenye ebalulekile yohlelo lwe-ICE injection (injection motor). Iphampu lokukhanda lisetshenziswa ezimotweni ezindala lapho kufakwa khona i-carburetor emotweni. Ngokuyinhloko, injini yokushisa yangaphakathi kaphethiloli ifakwe ipompo elilodwa likaphethiloli, kepha kukhona nokuguqulwa kwezimoto zomjovo ezinepompo yokulekelela (ngezinguqulo ezibandakanya ujantshi kaphethiloli). Injini kadizili ifakwe amaphampu amabili, elilodwa liphampu likaphethiloli elinamandla amakhulu. Kwakha ingcindezi ephezulu kulayini (idivayisi kanye nomgomo wokusebenza wedivayisi kuchazwe ngokuningiliziwe ngokwehlukana). Amaphampu wesibili enza uphethiloli, okwenza kube nensimbi enkulu esebenza kalula. Amaphampu adala ingcindezi ephezulu ezinjinini zikadizili anikwa amandla yi-plunger pair (lokho okuchazwa kukho lapha).
• I-Fuel cleaner. Izinhlelo eziningi zikaphethiloli zizoba nezihlungi okungenani ezimbili. Owokuqala uhlinzeka ngokuhlanza okunzima, futhi kufakwe ethangini legesi. Eyesibili yenzelwe ukuhlanzwa kahle kukaphethiloli. Le ngxenye ifakwe ngaphambi kokungena kusitimela kaphethiloli, ipompo kaphethiloli enomfutho ophakeme noma phambi kwe-carburetor. Lezi zinto ziyakwazi ukusetshenziswa futhi zidinga ukushintshwa ngezikhathi ezithile.
• Izinjini zikadizili zisebenzisa nemishini efudumeza uwoyela kadizili ngaphambi kokuthi ingene kwisilinda. Ukuba khona kwayo kungenxa yokuthi uphethiloli une-viscosity ephezulu emazingeni okushisa aphansi, futhi kuba nzima kakhulu ukuthi iphampu libhekane nomsebenzi walo, futhi kwezinye izimo alikwazi ukupompa uphethiloli kulayini. Kepha kumayunithi anjalo, ukuba khona kwamapulagi wokukhanya nakho kufanelekile. Funda ngokuthi zihluke kanjani kuma-spark plugs nokuthi kungani zidingeka. ngokwehlukana.

Ngokuya ngohlobo lwesistimu, ukwakheka kwayo kungafaka ezinye izinto ezihlinzeka ngomsebenzi omuhle wokuphakelwa kukaphethiloli.

Ngabe lusebenza kanjani uhlelo lukaphethiloli wemoto?

Njengoba kunezinhlobonhlobo zezimoto, ngayinye yazo inendlela yayo yokusebenza. Kepha imigomo esemqoka ayihlukile. Lapho umshayeli evula ukhiye esikrinini sokusha (uma kufakwe umjovo enjinini yomlilo yangaphakathi), kuzwakala umsindo omuncu ovela ohlangothini lwethangi legesi. Iphampu kaphethiloli yenziwe yasebenza. Kwakha ingcindezi epayipini. Uma imoto ishiswa ngophethiloli, khona-ke kunguqulo yakudala ipompo kaphethiloli iyimishini, futhi kuze kube yilapho iyunithi iqala ukujikeleza, i-supercharger ngeke isebenze.

Lapho i-starter motor ivula i-flywheel disk, zonke izinhlelo zezimoto ziphoqeleka ukuthi ziqale ngokuvumelanisa. Njengoba ama-piston ehamba emasilindini, ama-valve okufaka ekhanda lesilinda ayavuleka. Ngenxa yokuhlanza, igumbi lesilinda liqala ukugcwalisa umoya kokuphindaphindwayo kokudla. Ngalesi sikhathi, uphethiloli ufakwa emfuleni womoya odlulayo. Kulokhu, kusetshenziswa umbhobho (mayelana nokuthi le nto isebenza kanjani futhi isebenza kanjani, funda lapha).

Lapho ama-valve wesikhathi evala, kufakwa inhlansi enhlanganisweni yomoya / kaphethiloli ocindezelweyo. Lokhu kukhishwa kukhanyisa i-BTS, lapho kukhishwa khona inani elikhulu lamandla, elicindezela i-piston esikhungweni esiphansi esifile. Izinqubo ezifanayo zenzeka kumasilinda aseduze, futhi imoto iqala ukusebenza ngokuzimela.

Lesi simiso sokusebenza esijwayelekile sezimoto eziningi zesimanje. Kodwa okunye ukuguqulwa kwezinhlelo zikaphethiloli nakho kungasetshenziswa emotweni. Ake sicabangele ukuthi yini umehluko wabo.

Izinhlobo zezinhlelo zokujova

Zonke izinhlelo zomjovo zingahlukaniswa kabili:

• Izinhlobonhlobo zezinjini zomlilo zangaphakathi zikaphethiloli;
• Izinhlobonhlobo zezinjini zomlilo zangaphakathi zikadizili.

Kepha nakulezi zigaba, kunezinhlobo eziningana zezimoto ezizofaka uphethiloli ngendlela yazo emoyeni eziya emakamelweni angama-cylinder. Nayi umehluko omkhulu phakathi kohlobo lwemoto ngalunye.

Fuel izinhlelo izinjini uphethiloli

Emlandweni wemboni yezimoto, izinjini zikaphethiloli (njengezona zingxenye eziyinhloko zezimoto) zivele ngaphambi kwezinjini zikadizili. Njengoba umoya udingeka kumasilinda ukubasa uphethiloli (ngaphandle komoya-mpilo, akukho neyodwa into ezokhela), onjiniyela bakhiqize iyunithi yemishini lapho uphethiloli uxutshwa nomoya ngaphansi kwethonya lezinqubo zemvelo zomzimba. Kuya ngokuthi le nqubo yenziwa kanjani kahle noma ngabe uphethiloli uvutha ngokuphelele noma cha.

Ekuqaleni, lokhu kwakhiwa iyunithi ekhethekile, eyayiseduze ngangokunokwenzeka nenjini eningi yokudla. Lokhu yi-carburetor. Ngokuhamba kwesikhathi, kwacaca ukuthi izici zalo mshini zixhomeke ngqo kuzici zejometri zepheshana lokungenisa kanye namasilinda, ngakho-ke akuhlali njalo izinjini ezinjalo zinganikeza ibhalansi efanelekile phakathi kokusetshenziswa kukaphethiloli nokusebenza kahle okuphezulu.

Ngasekuqaleni kweminyaka yama-50s kwekhulu elidlule, kwavela i-analogue yomjovo, eyanikeza ukufakwa ngenkani kukaphethiloli ekugelezeni komoya okudlula ezininginingi. Ake sicabangele umehluko phakathi kwalezi zinguquko ezimbili zohlelo.

Carburetor uphethiloli uhlelo

Injini ye-carburetor kulula ukuyihlukanisa nenjini yomjovo. Ngaphezulu kwekhanda lesilinda kuzoba "nepani" eyisicaba okuyingxenye yohlelo lokudla, futhi kukhona isihlungi somoya kuso. Lesi sici sibekwe ngqo ku-carburetor. I-carburetor iyithuluzi elinamagumbi amaningi. Amanye aqukethe uphethiloli, kanti amanye awanalutho, okungukuthi, asebenza njengamapayipi omoya lapho kungena khona umfudlana womoya omusha kumqoqi.

I-carburetor ifakwa i-valve mpintsha. Eqinisweni, lesi ukuphela kwesilawuli enjinini enjalo esinquma inani lomoya ongena kumasilinda. Le nto ixhunywe ngeshubhu eguquguqukayo kusabalalisi benkcaso (ukuthola imininingwane mayelana nomsabalalisi, funda kwesinye isihloko) ukulungisa i-SPL ngenxa ye-vacuum. Izimoto zakudala zisebenzise idivayisi eyodwa. Ezimoto zezemidlalo, i-carburetor eyodwa ingafakwa nge-cylinder ngayinye (noma eyodwa yamabhodwe amabili), okwenyuse kakhulu amandla wenjini yomlilo yangaphakathi.

Amafutha anikezwa ngenxa yokudonswa kwezingxenye ezincane zikaphethiloli lapho ukugeleza komoya kudlula ngamajethi kaphethiloli (mayelana nokwakheka nenjongo yawo kuchazwa lapha). Uphethiloli umunzwa emfudlaneni, futhi ngenxa yomgodi omncane embhedeni, ingxenye isatshalaliswa izinhlayiya ezincane.

Ngaphezu kwalokho, lokhu kugeleza kwe-VTS kungena kumgudu wokungenisa okuningi lapho kwakhiwa khona i-vacuum ngenxa ye-valve yokuvula evulekile ne-piston eya phansi. Iphampu kaphethiloli ohlelweni olunjalo liyadingeka kuphela ukuze kupomfwe uphethiloli emgodini ohambisanayo we-carburetor (ikamelo lamafutha). Okuhlukile kwalolu lungiselelo ukuthi ipompo likaphethiloli linokuhlangana okuqinile nezindlela zamandla weyunithi yamandla (kuya ngohlobo lwenjini, kepha kumamodeli amaningi aqhutshwa yi-camshaft).

Ukuze ikamelo likaphethiloli le-carburetor lingagcwali futhi uphethiloli ungangeni ngokungalawuleki emigodini eseduze, amanye amadivayisi afakwe umugqa wokubuyela emuva. Ivumela uphethiloli oweqile ukuthi uphinde ubuye ungene ethangini legesi.

Uhlelo lwe-Fuel injection (uhlelo lokujova uphethiloli)

Umjovo weMono wenziwe njengenye indlela ye-carburetor yakudala. Lolu uhlelo olune-atomization ephoqelelwe yephethiloli (ukutholakala kombhobho kukuvumela ukuba uhlukanise ingxenye kaphethiloli ibe yizinhlayiya ezincane). Eqinisweni, lena yi-carburetor efanayo, kufakwa umjovo owodwa kuphela kokuphindaphindwayo esikhundleni sedivayisi yangaphambilini. Isivele ilawulwa yi-microprocessor, ebuye ilawule uhlelo lwe-electronic ignition (funda ngalo ngokuningiliziwe lapha).

Kulesi sakhiwo, ipompo likaphethiloli selivele lisebenza ngogesi, futhi lenza umfutho ophakeme, ongafinyelela ibha eningana (lesi sici sincike kudivayisi yomjovo). Imoto enjalo ngosizo lwe-elekthronikhi ingashintsha inani lokugeleza okungena ekusakazweni komoya omusha (shintsha ukwakheka kweVTS - yenze iphele noma icebise), ngenxa yokuthi wonke ama-injector abiza kakhulu kunezinjini ze-carburetor ezinomthamo ofanayo .

Ngokulandelayo, umjovo waguqukela kokunye ukuguqulwa okungagcini ngokwandisa ukusebenza kahle kokufafaza uphethiloli, kodwa futhi kuyakwazi ukuzivumelanisa nezindlela ezihlukile zokusebenza kweyunithi. Imininingwane mayelana nezinhlobo zezinqubo zomjovo ichaziwe esihlokweni esehlukile... Nazi izimoto eziyinhloko ezine-atomization ephoqelelwe yephethiloli:

1. Monoinjection. Sivele sibuyekeze kafushane izici zayo.
2. Umjovo osatshalalisiwe. Ngamafuphi, umehluko wayo ekuguqulweni kwangaphambilini ukuthi akuyona eyodwa, kepha kusetshenziswa imibhobho eminingana ukufafaza. Sezivele zifakiwe emapayipini ahlukile wokuphindaphindeka kokudla. Indawo yabo incike ohlotsheni lwemoto. Ezitshalweni zamandla zesimanje, ama-sprayers afakwa eduze ngangokunokwenzeka kuma-valve wokufaka okuvula. Isici se-atomizing ngasinye sinciphisa ukulahleka kukaphethiloli ngesikhathi sokusebenza kohlelo lokudla. Ukwakhiwa kwalezi zinhlobo zezimoto kunesitimela sikaphethiloli (ithangi elincane elenziwe elisebenza njengechibi lapho uphethiloli ungaphansi kwengcindezi). Le mojula ivumela uhlelo ukuthi lusabalalise uphethiloli ngokulinganayo kuwo wonke ama-injector ngaphandle kokudlidliza. Kuma-motors athuthukile, uhlobo lwebhethri lwemoto oluyinkimbinkimbi luyasetshenziswa. Lesi isitimela sikaphethiloli, lapho kukhona khona i-valve elawula ingcindezi yohlelo ukuze ingaqhumi (ipompo lomjovo likwazi ukudala ingcindezi ebucayi yamapayipi, ngoba iplanethi yeplunger isebenza kusuka ekuxhumeni okuqinile kuya iyunithi yamandla). Isebenza kanjani, funda ngokwehlukana... Ama-motors anomjovo we-multipoint abhalwe ukuthi i-MPI (injekethi yamaphoyinti amaningi ichazwe ngokuningiliziwe lapha)
3. Umjovo oqondile. Lolu hlobo lungezinhlelo zokufafaza uphethiloli ezinamaphoyinti amaningi. Okukhethekile ukuthi ama-injectors awekho ezininginingi zokudla, kepha ngqo ekhanda lesilinda. Leli lungiselelo livumela abenzi bezimoto ukuba bahlomise injini yomlilo yangaphakathi ngohlelo olucisha amasilinda amaningana kuye ngomthwalo oyunithi. Ngenxa yalokhu, noma injini enkulu kakhulu ingakhombisa ukusebenza kahle, yebo, uma umshayeli esebenzisa lolu hlelo ngendlela efanele.

Ingqikithi yokusebenza kwama-motor motors ihlala ingashintshiwe. Ngosizo lwepompo, uphethiloli uthathwa ethangini. Indlela efanayo noma ipompo yomjovo kudala ingcindezi edingekayo yokwenza i-atomization esebenzayo. Ngokuya ngokwakhiwa kohlelo lokungenisa, ngesikhathi esifanele, kunikezwa ingxenye encane kaphethiloli efuthwe ngombhobho (kwakhiwa inkungu kaphethiloli, ngenxa yokuthi i-BTC isha kahle kakhulu).

Izimoto eziningi zesimanje zifakwe i-ramp nesilawuli sengcindezi. Kule nguqulo, ukwehla kokushiswa kukaphethiloli kuncishisiwe, futhi kusatshalaliswa ngokulinganayo phezu kwama-injectors. Ukusebenza kohlelo lonke kulawulwa yiyunithi yokulawula ye-elekthronikhi ngokuya ngama-algorithms afakwe ku-microprocessor.

Izinhlelo zikadizili

Izinhlelo zikaphethiloli zezinjini zikadizili zimjovo oqondile kuphela. Isizathu silele kumgomo wokushisa i-HTS. Ekuguqulweni okunjalo kwama-motors, alukho uhlelo lokuthungela olunjalo. Ukuklanywa kweyunithi kusho ukucindezelwa komoya ku-cylinder kuze kube yilapho ushisa kuze kufike kumadigri angamakhulu amaningana. Lapho i-piston ifinyelela esikhungweni esiphezulu esifile, uhlelo lukaphethiloli lufafaza uphethiloli kusilinda. Ngaphansi kwethonya lokushisa okuphezulu, inhlanganisela yomoya nedizili iyafutha, kukhulule amandla adingekayo ekuhambeni kwe-piston.

Esinye isici sezinjini zikadizili ukuthi, uma kuqhathaniswa nozakwabo bakaphethiloli, ukuminyana kwazo kuphakeme kakhulu, ngakho-ke, uhlelo lukaphethiloli kufanele lwenze umfutho ophakeme kakhulu wephethiloli kadizili esitimeleni. Ngenxa yalokhu, kusetshenziswa kuphela ipompo yokucindezela ephezulu, esebenza ngesisekelo se-plunger pair. Ukungasebenzi kahle kwalesi sici kuzovimbela ukuthi imoto ingasebenzi.

Ukwakhiwa kwale moto kuzofaka amaphampu amabili kaphethiloli. Umuntu umane nje upompa uphethiloli uye koyinhloko, kanti oyinhloko udala ingcindezi edingekayo. Idivayisi nesenzo esisebenza kahle kakhulu uhlelo lwe-Common Rail fuel. Uchazwe ngokuningiliziwe kwesinye isihloko.

Nayi ividiyo emfushane yokuthi luhlobo luni lohlelo:

Ukuhlola ujantshi ojwayelekile. Imijovo kadizili.

Njengoba ukwazi ukubona, izimoto zesimanje zinezinhlelo zikaphethiloli ezingcono futhi ezisebenza kangcono. Kodwa-ke, lezi zinguquko zinenkinga enkulu. Yize besebenza ngokuthembekile ngokwanele, uma kwenzeka ukuwohloka, ukulungiswa kwabo kubiza kakhulu kunokusekela ozakwabo be-carburetor.

Amathuba wezinhlelo zesimanje zikaphethiloli

Ngaphandle kobunzima bokulungiswa kanye nezindleko eziphezulu zezinto ngazinye zezinhlelo zikaphethiloli zesimanje, abenzi bezimoto baphoqeleka ukuthi basebenzise lokhu kuthuthukiswa kumamodeli abo ngezizathu eziningana.

1. Okokuqala, lezi zimoto ziyakwazi ukuhlinzeka ngomnotho osezingeni elifanelekile uma kuqhathaniswa nama-carburetor ICE wevolumu efanayo. Ngasikhathi sinye, amandla enjini awanikelwa, kepha kumamodeli amaningi, kunalokho, ukwanda kwezimpawu zamandla kuyabonakala uma kuqhathaniswa nokuguqulwa okungakhiqizi kangako, kepha ngamavolumu afanayo.
2. Okwesibili, izinhlelo zikaphethiloli zesimanje zenza kube nokwenzeka ukuhlenga ukusetshenziswa kukaphethiloli kulayini ophikweni lwamandla.
3. Okwesithathu, ngokunciphisa inani likaphethiloli oshisiwe, imoto kungenzeka ukuthi ihlangabezane namazinga aphezulu emvelo.
4. Okwesine, ukusetshenziswa kwe-elekthronikhi kwenza ukuthi kungagcini ngokunikeza imiyalo kuma-actuator, kepha ukulawula zonke izinqubo ezenzeka ngaphakathi kweyunithi yamandla. Imishini yokusebenza kwemishini nayo iyasebenza impela, ngoba imishini ye-carburetor ayikasasebenzi, kepha ayikwazi ukuguqula izindlela zokunikezwa kukaphethiloli.

Ngakho-ke, njengoba sesibonile, izimoto zesimanje azivumeli kuphela imoto ukuthi ishayele, kodwa futhi zisebenzisa amandla aphelele edonsi ngalinye likaphethiloli, zinika umshayeli injabulo ekusebenzeni okunamandla kweyunithi yamandla.

Ekuphetheni - ividiyo emfushane mayelana nokusebenza kwezinhlelo ezahlukahlukene zikaphethiloli:

Yiziphi izinhlobo zomjovo enjinini kaphethiloli nodizili, ahluke kanjani nokuthi yimuphi umjovo ongcono

Imibuzo nezimpendulo:

Lusebenza kanjani uhlelo lukaphethiloli? Ithangi likaphethiloli (ithangi legesi), iphampu kaphethiloli, ulayini wamafutha (umfutho ophansi noma ophezulu), izifutho (imibhobho, kanye namamodeli amadala i-carburetor).

Luyini uhlelo lukaphethiloli emotweni? Lolu uhlelo oluhlinzeka ngokugcinwa kokuphakelwa kukaphethiloli, ukuhlanzwa kwawo kanye nokupompa kusuka ethangini legesi kuya enjinini ukuze kuhlanganiswe nomoya.

Hlobo luni lwamasistimu kaphethiloli akhona? I-Carburetor, umjovo we-mono (i-nozzle eyodwa ngokomgomo we-carburetor), umjovo osakazwayo (umjovo). Umjovo osakazwayo uhlanganisa nomjovo oqondile.
