Injini ye-Renault M5Pt
Ngokokuqala ngqá, abakhi injini French ngokuzimela (ngaphandle kokuxoxisana "Nissan") ithuthukiswe injini entsha yomugqa TCe. Inhloso enkulu ukufaka ku-flagship nezinhlobo zezemidlalo zezimoto zakwaRenault.
Incazelo
Ukukhiqizwa kweyunithi yamandla kwaqala ngo-2011 embonini yaseSeoul (eNingizimu Korea). Futhi kuphela ngo-2017 wethulwa okokuqala embukisweni wezimoto zomhlaba wonke.
Uchungechunge lwenjini ye-M5Pt lunezinguqulo ezimbalwa. Owokuqala uwumgomo ojwayelekile, noma owomphakathi, kanti amabili awomdlalo. Umehluko usemandleni eyunithi (bheka ithebula).
I-M5Pt iyinjini engu-1,8-litre turbocharged four-cylinder kaphethroli enamandla angu-225-300 hp. nge-torque engu-300-420 Nm.
Kufakwe ezimotweni zakwaRenault:
- I-Espace V (2017-n/vr);
- I-Talisman I (2018-n/vr);
- I-Megane IV (2018-n/vr).
Ngaphezu kwalezi zinhlobo, injini ifakwe ku-subsidiary Alpine A110 kusukela ngo-2017 kuze kube manje.
Ibhulokhi yesilinda ye-Aluminium ehlanganiswe namalayini ensimbi. I-cylinder head nayo iyi-aluminium, inama-camshaft amabili nama-valve angu-16. Izilawuli zesigaba azizange zifakwe kunguqulo yemoto yabantu, kodwa kwezemidlalo kwakukhona eyodwa ku-shaft ngayinye.
Izinjini ezivuthayo zangaphakathi azifakelwe izinxephezelo zamanzi. Ukucaciswa okushisayo kwama-valve kulawulwa ukukhethwa kwama-pusher ngemuva kwamakhilomitha ayizinkulungwane ezingu-80 wemoto.
Isikhathi se-chain drive. Insiza ye-chain-free chain chain ingama-250 XNUMX km.
Ukufaka i-turbocharging, kusetshenziswa i-low-inertia turbine evela kwaMitsubishi. Izinguqulo zezemidlalo zenjini zifakwe ama-turbocharger e-Twin Scroll athuthuke kakhulu.
Isistimu yokujova amafutha ngomjovo oqondile wamafutha.

Ukuthembeka
Injini ye-M5Pt ibhekwa njenge-powertrain ethembekile kakhulu, ikakhulukazi uma iqhathaniswa ne-M5Mt. I-turbine inempilo yesevisi ephezulu kakhulu (izinkulungwane ezingama-200 km). Iketanga lesikhathi nalo linomkhawulo omkhulu wokuphepha.
Ukungabikho kwezilawuli zesigaba kumodeli eyisisekelo yeyunithi kugcizelela ukwethembeka kwayo. Kuyaziwa ukuthi baqala ukwehluleka ngemva ayizinkulungwane 70 km of car run, ngezinye izikhathi inkathazo enjalo kwenzeka ngaphambili.
Ngesevisi efika ngesikhathi kanye nekhwalithi ephezulu, ukusebenza okungezona ulaka, nokusetshenziswa koketshezi olusezingeni eliphezulu lobuchwepheshe, injini iyakwazi ukusebenza ngaphezu kwezinkulungwane ezingama-350 km ngaphandle kokuphazamiseka okubalulekile.
Izindawo ezibuthakathaka
Ukuthembeka okuphezulu kwenjini yomlilo yangaphakathi akuqedi ukuba khona kobuthakathaka. I-motor ayifanele ukusebenza emazingeni okushisa aphansi azungezile.
Esimweni sezulu esibandayo, ukuqhwa kwe-throttle valve kanye nokubanda komugqa wegesi ye-crankcase kuyabonwa. Esimweni sokuqala, i-trust yenjini iyalahleka, okwesibili, uwoyela ukhishwa ohlelweni lokuthambisa (ngezinye izikhathi nge-dipstick yamafutha).
Isikhathi sokushayela. Ngokushayela okunolaka, iketango alikwazi ukubhekana nemithwalo eyeqile, liyanwebeka. Kukhona ingozi yokugxuma, okuzophumela kuma-valve agobile. Inkathazo enjalo izibonakalisa ngamakhilomitha ayizinkulungwane eziyi-100-120.
Ngokunwebeka, ukuntuleka kwama-hydraulic lifters kungabangelwa amaphuzu abuthakathaka.
Okunye ukuwohloka okwenzeka akukona okubalulekile, kunezimo ezingazodwa (isivinini sokungenzi lutho esintantayo, ukwehluleka kukagesi, njll.), imbangela eyinhloko ehlotshaniswa nokungalungiswa kahle kwenjini.
Ukulondolozeka
Kumele kuqashelwe ukuthi injini yomlilo yangaphakathi ayihlukaniswa nokugcinwa okuphezulu. Indima eyinhloko kulokhu idlalwa i-aluminium (funda: elahlayo) i-cylinder block. Ukuphinda kuhlinzwe kungenzeka kuphela ebhulokhini elifanele le njongo.
Azikho izinkinga ekutholeni izingxenye ezisele ezidingekayo ukuze zilungiswe, kodwa lapha udinga ukucabangela izindleko zazo eziphakeme kakhulu.
Uma uthanda, ungathola injini yenkontileka bese uyishintsha ngehlulekile.
Ngakho-ke, isiphetho kuphela singafinyelelwa - injini ye-M5Pt iyunithi enokwethenjelwa ngokuphelele ngokunamathela ngokuqinile ezincomo zomenzi.
