Двигатель Mitsubishi 4b12
Okuqukethwe
I-in-line four-cylinder ICE 4b12 enevolumu engu-2.4 litres yathuthukiswa ngokuhlanganyela ngabakwaMitsubishi kanye neKia-Hyundai. Le njini inesinye isibizo - g4ke. Kufakwe ezimotweni ze-Mitsubishi Outlander, kanye nezinye izimoto eziningi. Inezici zokusebenza ezinhle kakhulu.
Incazelo injini, izici zayo eziyinhloko
Iyunithi evela kumkhiqizi iMitsubishi imakwe njenge-4b12. Ngokuvamile ungathola igama elithi g4ke - lawa ma-motor amabili ahlukene acishe afane ngezici zawo futhi ayashintshana. Ngakho-ke, kungenzeka ukufaka esikhundleni se-g4ke nge-4b12. Kodwa kubalulekile ukukhumbula izici zokushintshwa kwe-4b12. Womabili amayunithi awomndeni wakwaTheta II.
Lolu chungechunge lweMitsubishi luhlanganisa ne-4b1. Injini engu-4b12 okukhulunywa ngayo ilandela ngqo injini engu-4G69. Ngakho-ke, wazuza njengefa izici zayo eziningi, kuhlanganise nezinkinga ezithile ezibalulekile. Futhi, lezi zinjini zisetshenziswa ezimotweni zeChrysler World. Eqinisweni, i-4b12 motor okukhulunywa ngayo iyinguqulo ekhulisiwe yamamodeli we-g4kd / 4b11std.
Ukwanda kwe-motor ngokwayo kungenxa yobukhulu obukhulu be-crankshaft - ukushaywa kwe-piston okunjalo kuzoba 97 mm esikhundleni sika-86 enguqulweni encane. Umthamo wokusebenza okungu-2 amalitha. Ukufana okuyinhloko komklamo wenjini engu-4b12 namamodeli amancane we-g4kd nama-analogue:
- uhlelo olufanayo lokushintsha isikhathi se-valve - kuwo womabili ama-shafts;
- ukungabi khona kwama-hydraulic lifters (okwenza kube lula ukushintshwa kwenjini - uma kuphakama isidingo).
Naphezu kobubi obuthile benjini, inezinzuzo eziningi. Izinga likawoyela kumele liqashwe ngeso lokhozi. Kusukela 4b12 zihlukaniswa ezinye "voracity". Umkhiqizi uncoma ukuthi kushintshwe zonke izinkulungwane eziyi-15 km, kodwa isixazululo esingcono kakhulu kungaba ushintsho njalo ngezinkulungwane eziyi-10 km - lokhu kuzobambezela isidingo sokulungiswa okukhulu isikhathi esiphezulu.
Izinjini ze-4b12 kanye ne-g4ke zingamakhophi aqondile enye yazo. Njengoba lezo zathuthukiswa ngaphansi kohlelo olukhethekile "World Engine". Lawa ma-motor afakwe:
- I-Outlander;
- IPeugeot 4007;
- Citroen C crosser.
4b12 imininingwane yenjini
Ngokwehlukana, kufanele kuqashelwe idivayisi yesikhathi - ayinikezwanga ngebhande, kodwa ngeketanga. Lokhu kwandisa kakhulu insiza yomshini ngokwawo. I-chain chain kufanele ishintshwe njalo ngezinkulungwane eziyi-150 km. Kubalulekile ukusetha ngokunembile i-torque yokuqinisa. Ngenxa yezici zobuchwepheshe, abashayeli abaningi bezimoto bakulungele ukuvala amehlo ezingozini eziningi ze-4b12 injini - "idla" uwoyela, kukhona ukudlidliza okuthile ngesikhathi sokusebenza (futhi lokhu kuvame ukuzibonakalisa ngokuzenzakalelayo).
Isisetshenziswa esimenyezelwe ngumkhiqizi singamakhilomitha ayizinkulungwane ezingama-250. Kodwa ekusebenzeni, ama-motor anjalo anakekela i-oda lobukhulu obungaphezulu - izinkulungwane ezingama-300 km nangaphezulu. Yini eyenza ukuthengwa nokufakwa kwenjini yenkontileka kube yisixazululo esinenzuzo. Izici ezilandelayo zithinta insiza yemoto ethile:
- kangaki amakhandlela, izihlungi zamafutha kanye namafutha ngokwawo ashintshwa;
- izinga likaphethiloli osetshenzisiwe;
- indlela yokusebenza - kuyadingeka ukwenza ukulungiswa ngesikhathi esifanele uma kunesidingo, ulungise ama-valve;
- ukufudumala ngaphambi kokuqala injini - lokhu kubaluleke kakhulu uma usebenza ebusika.

- ukudlidliza okwandisiwe - ngokuvamile okuhlotshaniswa nesidingo sokushintsha amakhandlela.
Kubalulekile ukunaka i-cylinder block. I-crankshaft ngokuvamile ayidingi ukushintshwa, kodwa kuyadingeka ukuqapha isimo sezintambo zokuxhuma.
Ukuphuka okudinga ukususwa kwenjini ukuze kulungiswe kwenzeka kaningi uma kuqhathaniswa. Kubalulekile ukuqapha isimo sebhande le-alternator futhi ubeke esikhundleni salo ngesikhathi esifanele. Le nqubo ayiyona inkimbinkimbi, kungenzeka ukuyifeza egaraji - njengamanye amaningi okulungisa.
Ezinye izinkinga ngezinye izikhathi ziphakama lapho kususwa ikhanda le-cylinder - ikhanda le-cylinder. Izinqubo ezinjalo, ngokungabikho kokuhlangenwe nakho namathuluzi afanelekile, zenziwa kangcono enkonzweni ekhethekile. Lapho wenza umsebenzi wokulungisa, kungakuhle ukuthi uthenge izingxenye zangempela kuphela. Ibhande lokushayela livela kwaBosch, ama-liner avela eTaiho, ezinye izinkampani ezaziwayo. Lokhu kuzonciphisa amathuba okuthenga imikhiqizo enesici, okuholela ekuhlulekeni kwenjini ngokuzayo.
Ukuthenga ibhande, kanye namafutha nezinye izinto ezisetshenziswayo, ngeke kubize. Kodwa izingxenye ezifana nenzwa ye-crankshaft, i-camshaft ne-egr valve izobiza izinkulungwane zama-ruble ayizinkulungwane ezimbalwa noma ngaphezulu. I-4b12 ifakwe i-CVT ethembekile kwezinye izinhlobo zezimoto, kukhona namazinga amaningi okunquma ngebhokisi le-manual. Lapho ulungisa, kubalulekile ukukala ngokunembile ubukhulu be-crankshaft - lokhu kuzokwenza kube lula ukukhethwa kwezingxenye.
Ukugcinwa, impilo yesevisi yendlela yokusabalalisa igesi
Kubalulekile ukwenza ucwaningo lwesikhathi ngesikhathi esifanele. Uma kungenjalo, uma izingxenye zalo mshini ziphuka, kungase kudingeke ukuba kulungiswe yonke injini. Kuyaphawuleka ukuthi ukuqaqa injini ukulungisa isikhathi kulula, kodwa kudinga amakhono namathuluzi akhethekile. Uma kungenjalo, imininingwane ebalulekile yesakhiwo ingase yonakaliswe. Isibonelo, i-timing belt tensioner. Kuhlakazwe ngesikhathi sokulungiswa kwe-4b12 kubukeka kanje:
Le njini iqala ukusebenzisa uwoyela owengeziwe kunomkhawulo obekwe embonini ngumenzi wezimoto. Kodwa ngesikhathi esifanayo, kuphela endaweni uphawu mileage 180 km. Ngemuva kwe-disassembly, kuzodingeka ugeze zonke izingxenye ezimbozwe ngezimayini, i-soot. I-Deca noma i-Dimer isetshenziselwa lokhu.
Ngokuvamile, izinkinga ezilandelayo zivela ngesikhathi sokulungiswa:
- ukuhlakazwa kwezinduku zokuxhuma namapiston;
- khipha ipuleti elingezansi lenjini.
Kule misebenzi, uzodinga ithuluzi elikhethekile. Insiza ye-chain chain yi-200 ayizinkulungwane km. Kodwa le nkomba ithinteka kakhulu ngekhwalithi yamafutha asetshenzisiwe. Kubalulekile ukuhlola ngezikhathi ezithile ukunwetshwa kweketango, ubude bayo buzokhula. Uma ushintsha, kufanele kukhunjulwe ukuthi kukhona amasampula amabili ahlukene ale ngxenye - amaketanga ezinhlobo ezindala nezintsha. Ziyakwazi ukushintshashintsha.
Izimpawu eziyinhloko zokuthi iketango lesikhathi lidinga ukushintshwa:
- kukhona imisindo "ecwayizayo" "emakhazeni";
- kukhona ukulahlekelwa amandla;
- i-chain slack - ingabonakala lapho ikhava isusiwe.
Njengakwezinye izimoto, kubalulekile ukuthi izinjini zalolu hlobo zifake iketango ngokwamamaki akhethekile ngesikhathi. Uma kungenjalo, injini ngeke iqale noma izosebenza izikhawu.
Kubalulekile ukukhumbula: uchungechunge lwesikhathi olusha kungenzeka lungabi nazo izixhumanisi ezipendiwe zokwenza ukufakwa kube lula.
Ngakho-ke, ngaphambi kokukhipha endala, udinga ukuqoka amamaki anjalo ngokwakho. Amamaki kuma-sprocket e-camshaft amakwe ngamamaki akhethekile esithombeni:
Imaphi amafutha ongawasebenzisa enjini engu-4b12
Ukukhethwa kwamafutha kule moto kuyinkinga engathi sína. Impilo yesevisi yesikhathi, kanye nezinye izindlela ezibalulekile nezinhlelo zenjini, kuncike kwikhwalithi yokugcoba. Ngokwezincomo zomkhiqizi, kuyadingeka ukusebenzisa amafutha ane-viscosity ye-0W-20 kuya ku-10W-30, kuye ngezimo zezulu nezimo zokusebenza.
Kukhona ukucaciswa mayelana nenjini ye-4b12:
- I-API SN, SM;
- I-ILSAC GF-5;
- I-ACEA A1 / A5 - kungenzeka ukusebenzisa uwoyela ngaphandle kwalokhu kucaciswa, njengoba lesi sihloko singesiYurophu.
Isixazululo elilungile lapho ukhetha uwoyela izimoto nge injini 4b12 esimweni ukusebenza eRussian Federation - Moby 1 X1 5W-30. Kodwa kubalulekile ukuzijwayeza ngezimpawu zamafutha omgunyathi kusengaphambili. Ukusetshenziswa kwezimpahla zomgunyathi kungase kubangele umonakalo. Isibonelo, ngokukhuphuka kwe-viscosity kawoyela emazingeni okushisa angaphansi kweziro, angase akhanywe ngaphandle kwe-crankshaft oil seal, omunye umonakalo uzoholela esidingweni sokulungisa kabusha okukhulu.
Shintshanisa i-4b12 kwezinye izimoto
Injini engu-4b12 inobukhulu obujwayelekile futhi ingashintshwa enye injini efana nayo yonke imingcele yayo kanye neminye. Ukushintshwa okufanayo kwenzeka, isibonelo, ezimotweni zeMitsubishi lancer GTs 4WD. Kulezi zinhlobo, 4b11 ukuze 4b12 ukushintshanisa injini. Umthamo wokuqala uzoba 2 amalitha, owesibili - 2.4 amalitha. Inqubo ilula kakhulu:
- ukuhlakaza injini endala emzimbeni;
- ukufakwa kwezinamathiselo, ukungena kanye nezintambo ku-motor entsha;
- ukufakwa kwenjini entsha enazo zonke izinto zokusebenza emzimbeni wemoto esihlalweni.
