Injini ye-Mitsubishi 6G72
Okuqukethwe
Le njini ngeyochungechunge oludumile lwe-6G yakwaMitsubishi. Izinhlobo ezimbili ze-6G72 zaziwa: i-valve engu-12 (i-camshaft eyodwa) ne-24-valve (ama-camshaft amabili). Zombili ziyi-6-cylinder V-engine ene-camber angle eyandisiwe kanye nama-camshafts angaphezulu / ama-valve ekhanda lesilinda. Injini engasindi eyathatha indawo ye-6G71 yahlala kulayini wokuhlanganisa iminyaka engu-22, kwaze kwaba yilapho kufika i-6G75 entsha.
Incazelo yenjini
Cabangela izici eziyinhloko zale njini.
- I-crankshaft ye-injini isekelwa ama-bearings angu-4, izembozo ezihlanganiswe embhedeni ukuze kwandiswe ukuqina kwe-cylinder block.
- Ama-pistons enjini asakazwa ku-aluminium alloy, axhunywe ngephini elintantayo kwintonga yokuxhuma.
- Amasongo e-piston ayinsimbi ephonswe: enye inendawo ekhonkolo ene-bevel.
- Izindandatho ezihlanganisiwe ze-oil scraper, uhlobo lwe-scraper, olunikezwe i-spring expander.
- Ekhanda le-cylinder, amakamelo okushisa ohlobo lwetende atholakala.
- Ama-valve enjini enziwe ngensimbi ephikisayo.
- Izinxephezelo ze-Hydraulic zinikezwa ukulungiswa kokugunyazwa okuzenzakalelayo kudrayivu.
Umehluko phakathi kwezinhlelo ze-SOHC ne-DOHC ufanele ukunakwa okukhethekile.
- I-camshaft ye-SOHC iphonswe, enama-bearings angu-4, kodwa inguqulo ye-DOHC camshafts inama-bearings angu-5 ahlanganiswe namakhava akhethekile.
- Ibhande le-timing lenjini elinama-camshaft amabili lilungiswa yi-automatic tensioner. Ama-roller asakazwa ku-aluminium alloy, abe nempilo ende yesevisi.
Siphawula ezinye izici.
- Umthamo wenjini awushintshile ekushintsheni okuhlukahlukene - ncamashi 3 amalitha.
- Ama-piston e-aluminium avikelwe nge-graphite coating.
- Amakamelo omlilo atholakala ngaphakathi kwekhanda le-cylinder, amise okwetende.
- Ukufakwa komjovo oqondile we-GDI (ekuhlelweni kwakamuva kwe-6G72).
Okunamandla kakhulu ekulungisweni kwezinjini ze-6G72 kwakuyinguqulo ye-turbo, ethuthukisa i-320 hp. Nge. Imoto enjalo yafakwa ku-Dodge Steel kanye ne-Mitsubishi 3000 GT.
Kuyaphawuleka ukuthi ngaphambi kokufika komndeni wakwaCyclon, i-MMC yaneliseke ngokuphelele ngabane abakulayini. Kodwa ngokufika kwama-SUV amakhulu, ama-minivans nama-crossovers, kunesidingo samayunithi anamandla. Ngakho-ke, ku-line "ezine" zathathelwa indawo "eziyisithupha" ezimise okwe-V, futhi ezinye izinguquko zathola ama-camshaft amabili nekhanda lesilinda.
Umkhiqizi ugxile kokulandelayo ngesikhathi sokwenziwa kwamamotho amasha:
- uzama ukwandisa amandla, waphendukela ekusebenziseni inguqulo ye-turbocharged;
- ezama ukunciphisa ukusetshenziswa kukaphethiloli, wenza uhlelo lwe-valve lube lwesimanjemanje.
Ukusetshenziswa kukawoyela i-6G72 kunyuswe kwafinyelela ku-800 g/1000 km ngenxa yezinto ezithile zobuchwepheshe. Ukulungiswa kabusha kungazimemezela ngemuva kokugijima kwezinkulungwane eziyi-150-200.
Abanye ochwepheshe bachaza anhlobonhlobo ukuguqulwa 6G72 ngokuthi kungenzeka ukushintshashintsha amandla injini. Ngakho-ke, ingakhiqiza, kuye ngokuthi inguqulo: 141-225 hp. Nge. (ukuguqulwa okulula ngama-valve angu-12 noma angu-24); 215-240 l. Nge. (inguqulo ngomjovo wamafutha oqondile); 280-324 l. Nge. (inguqulo ye-turbocharged). Amanani we-torque nawo ayahluka: ezinguqulweni ezijwayelekile zomkhathi - 232-304 Nm, kuma-turbocharged - 415-427 Nm.
Ngokuqondene nokusetshenziswa kwama-camshafts amabili: naphezu kokuthi umklamo wama-valve angu-24 uvele ngaphambili, uhlelo lwe-DOHC lwalusetshenziswa kuphela kusukela ekuqaleni kwe-90 yekhulu leminyaka elidlule. Izinguqulo zangaphambilini ezinama-valve angu-24 zine-camshaft eyodwa kuphela. Abanye babo basebenzisa umjovo oqondile we-GDI, okwandisa isilinganiso sokucindezela.
Inguqulo ye-turbocharged ye-6G72 ifakwe i-compressor ye-MHI TD04-09B. Ama-cooler amabili abhangqwe nayo, njengoba i-intercooler eyodwa ayikwazi ukunikeza ivolumu yomoya edingekayo kumasilinda ayisithupha. Ohlelweni olusha lwenjini engu-6G72, kusetshenziswe ama-piston athuthukisiwe, ama-coolers kawoyela, ama-nozzles, nezinzwa.
Kuyathakazelisa ukuthi emakethe yaseYurophu, izinjini ze-6G72 turbo zafika ne-compressor ye-TD04-13G. Lolu khetho luvumele isikhungo sikagesi ukuthi sifinyelele amandla angu-286 amalitha. Nge. nge-boost pressure ye-0,5 bar.

Izinzuzo nokungalungi
Idizayini enokwethenjelwa nenempilo ephezulu yenjini engu-6G72 isindisa umnikazi ezindlekweni ezengeziwe. Uma abanikazi be-6G71 bekufanele baye esiteshini sesevisi njalo ngamakhilomitha ayizinkulungwane ezingu-15 ukulungisa ama-valve, khona-ke izinto zingcono kakhulu ngenjini entsha.
Nokho, amanye amaphutha asala. Ikakhulukazi, lokhu kuthinta ubunzima bokugcinwa, ukushisa ngokweqile nokubhujiswa kwama-valve.
- Ukugcinwa kwenjini kuyinkimbinkimbi ngenxa yokuthi ikhanda le-cylinder lihlukaniswe izingxenye ezimbili. Ngaphezu kwalokho, uhlelo olunjalo luthinta ukwanda kokusetshenziswa kukawoyela - ukugcoba ngokweqile kusetshenziselwa ukugcina ama-hydraulic lifters.
- Ukushisa okweqile kwenjini enamandla akunakugwenywa emjikelezweni wokushayela wasemadolobheni, lapho injini idinga "ukuvinjelwa", isebenze isivinini esiphansi kuphela.
- Ama-valve agobile ngenxa yokushelela njalo kwebhande lesikhathi. Ukulungiswa okuzenzakalelayo kusiza ukuqeda ikhefu, kodwa ibhande liyashelela ezimweni ezithile futhi lisagoba ama-valve.
Okunye okungalungile kwe-6G72 ukuhlukahluka kwemiklamo yenjini. Lokhu kwenza kube nzima ukulungisa, njengoba izinhlelo zezingxenye namasethi ezinjini zomlilo zangaphakathi ezine-camshaft eyodwa nezimbili zihluke ngokuphelele.
Ama-nuances wokunakekelwa okujwayelekile
Enye yezinkinga eziyinhloko ohlelweni lokunakekelwa kwenjini engu-3 litre ukushintshwa kwebhande lesikhathi ngemva kokugijima kuka-90. Ngisho nangaphambili, njalo ngamakhilomitha ayizinkulungwane ezingu-10, isihlungi samafutha kufanele sishintshwe. Funda kabanzi mayelana nokulungiswa okuhleliwe.
- Ukushintshwa kwezinzwa zomoya-mpilo njalo ngamakhilomitha ayizinkulungwane eziyi-10.
- Isheke le-Exhaust eliphindwe kabili njalo eminyakeni emibili.
- Ukulawulwa kwesistimu kaphethiloli kanye ne-crankcase ventilation ngemuva kwamakhilomitha ayizinkulungwane ezingama-30.
- Ukushajwa kabusha kwebhethri nokushintshwa njalo eminyakeni emi-3-4.
- Ukushintsha kwesiqandisi kanye nokubuyekezwa okuphelele kwawo wonke amapayipi, ukuxhumana ekuqaleni kwamakhilomitha ayizinkulungwane ezingu-30.
- Ukufakwa kwezihlungi ezintsha zikaphethiloli kanye nama-cartridges omoya ngemuva kwamakhilomitha ayizinkulungwane ezingama-40.
- Ukushintshwa kwama-spark plug njalo ngamakhilomitha ayizinkulungwane ezingu-30.
Ukungasebenzi kahle okukhulu
Ake sicabangele ngokuningiliziwe "izilonda" ezithandwayo ze-6G72, okwenza kube iyunithi evamile engakwazi ukubizwa ngokuthi i-super-reliable.
- Ijubane lokubhukuda ngemuva kokuqala libangelwa ukuvala i-throttle kanye nokuthuthukiswa komlawuli we-XX. Isixazululo sibandakanya ukuhlanza, ukulungisa nokufaka inzwa esikhundleni.
- Ukwanda kokusetshenziswa kukaphethiloli kukhombisa ukuthuthukiswa kwama-valve stem seal kanye nokuvela kwamasongo e-piston. Ngokusobala, lezi zakhi zizodinga ukushintshwa.
- Ukungqongqoza ngaphakathi kwenjini, okuchazwa ukuthuthukiswa kwamagobolondo aphethe induku yokuxhuma kanye nokuguga kwama-pusher we-hydraulic. Isixazululo sibandakanya ukushintsha amalayini kanye neziphakamisi ezinama-hydraulic.
Ngokusho komkhiqizi, ukusetshenziswa kukaphethiloli wekhwalithi enhle (uphethiloli one-OC ongekho ngaphansi kwe-AI-95) kuqinisekisa impilo ende yenjini.
Isimanje
Abaklami baqale babeka ikhono elikhulu kule njini. Ngaphandle kokulahlekelwa insiza, ingathuthukisa kalula i-350 hp. Nge. Ochwepheshe batusa ukuthi ungathuthukisi nge-turbocharging. Ngokombono wabo, izinguquko ezilandelayo zingenziwa.
- Khulisa ububanzi be-muffler futhi ukhanyise kabusha i-electronics.
- Shintsha iziphethu ezijwayelekile ngamandla angu-28 kg ngamamodeli anamandla angakwazi ukumelana no-40 kg.
- Rebore izihlalo futhi ufake ama-valve amakhulu.
Qaphela ukuthi ukulungiswa kwe-atmospheric kuzokwenza kube nokwenzeka ukwandisa amandla ngamalitha angu-50. Nge. Ukuguqulwa kwe-6G72 kuzobiza kancane kakhulu kunokushintshaniswa (ukushintshwa kwenjini).
