Injini ye-Mercedes-Benz M275
Uchungechunge lwe-M275 lwezinjini luthathe indawo ye-M137 engasasebenzi. Ngokungafani neyandulelayo, injini entsha isebenzise amasilinda anobubanzi obuncane, iziteshi ezimbili zokujikeleza okupholile, ukunikezwa kukaphethiloli okuthuthukisiwe kanye nesistimu yokulawula i-ME 2.7.1.
Incazelo yezinjini ze-M275
Injini ye-M275
Ngakho-ke, umehluko phakathi kwenjini entsha yangaphakathi evuthayo imi kanje:
- ubukhulu bamasilinda ku-circumference bancishiswa baba ngu-82 mm (ku-M137 yayingu-84 mm), okwenza kube nokwenzeka ukunciphisa umthamo wokusebenza ube ngamalitha angu-5,5 futhi uqinise isikhala esikhululekile phakathi kwezakhi ze-CPG;
- ukwanda kokuhlukaniswa, okwenza kube nokwenzeka ukwenza iziteshi ezimbili zokujikeleza kwe-antifreeze;
- isistimu ye-ZAS engasebenzi kahle, evala amasilinda ambalwa ekulayisheni kwenjini encane kanye nokulungisa ukuchayeka kwe-camshaft, isuswe ngokuphelele;
- isistimu yokuphatha injini ye-elekthronikhi isithathelwe indawo inguqulo yesimanje;
- i-DMRV yaqedwa - esikhundleni salokho kwasetshenziswa izilawuli ezimbili;
- kukhishwe ama-lambda angu-4, okunikeza ukusebenza kahle okukhulu enjini;
- ukuze uthole ukulawulwa okungcono kwengcindezi kaphethiloli, i-fuel fuel ihlanganiswe neyunithi yokulawula kanye nesihlungi esilula - ipompo ye-fuel engalawulwa ifakwe ku-M137, kufaka phakathi inzwa ehlanganisiwe;
- umshini wokushisa ngaphakathi kwe-cylinder block wasuswa, futhi i-radiator evamile yafakwa endaweni yayo ngaphambili;
- i-centrifuge yengezwe ohlelweni lokukhipha umoya wokukhipha umoya;
- ukucindezela kuncishiswe ku-9.0;
- i-scheme yasetshenziswa nama-turbines amabili ashumekwe kuma-multifold exhaust - i-boost ipholiswa ngamashaneli amabili abekwe phezulu kwekhanda le-cylinder.
Kodwa-ke, i-M275 isebenzisa isakhiwo esifanayo se-valve engu-3 esisebenze kahle ku-M137.
Funda kabanzi mayelana nomehluko phakathi kwezinjini ze-M275 ne-M137.

Isistimu ye-M275
Injini yesistimu ye-M275
Manje mayelana nezinhlelo zenjini entsha.
- I-Timing chain drive, imigqa emibili. Ukuze unciphise umsindo, kusetshenziswa irabha. Ihlanganisa ama-parasitic kanye nama-crankshaft sprockets. I-Hydraulic tensioner.
- Iphampu kawoyela inezigaba ezimbili. Ishayelwa iketango elihlukile elifakwe isiphethu.
- Isistimu yokulawula imoto ye-elekthronikhi ayihlukile kakhulu kunenguqulo ye-ME7. esetshenziswe eyandulelayo. Izingxenye eziyinhloko kuseyimojuli emaphakathi namakhoyili. Uhlelo olusha lwe-ME 2.7.1 ludawuniloda ulwazi kumasensa amane okushaya - lena isignali yokugudluza i-PTO iye ekuthutheni sekwephuzile.
- Isistimu ye-boost ixhunywe ku-exhaust. Ama-compressor alungiswa kusetshenziswa izingxenye ezingenamoya.
Injini engu-M275 yakhiwe ngendlela eyi-V. Ingenye yamayunithi angama-cylinder ayishumi nambili aphumelele, abekwe kahle ngaphansi kwesivalo semoto. I-motor block ibunjwe kusuka ku-lightweight refractory material. Ekuhlolweni okuqondile, kuvela ukuthi ukwakheka kwenjini evuthayo yangaphakathi kunzima kakhulu ukwenza iningi lamashaneli nokunikezela ngamapayipi. I-M275 inamakhanda amasilinda amabili. Zibuye zenziwe ngezinto ezinamaphiko, zibe nama-camshaft amabili ngayinye.
Ngokuvamile, injini ye-M275 inezinzuzo ezilandelayo ngaphezu kowandulelayo nezinye izinjini zeklasi ezifanayo:
- ukumelana kahle nokushisa ngokweqile;
- umsindo omncane;
- izinkomba ezinhle kakhulu zokukhishwa kwe-CO2;
- isisindo esincane ngokuzinza okuphezulu.
I-Turbocharger
Kungani kwafakwa i-turbocharger ku-M275 esikhundleni semishini? Okokuqala, kwaphoqeleka ukuba kwenziwe ngezitayela zesimanje. Uma ngaphambili kwakukhona isidingo se-supercharger yemishini ngenxa yesithombe esihle, namuhla isimo sishintshe kakhulu. Okwesibili, abaklami bakwazi ukuxazulula inkinga yokubeka injini ngaphansi kwe-hood - futhi babevame ukucabanga kanjalo - i-turbocharger idinga isikhala esiningi, ngakho-ke ukufakwa enjini yesisekelo akunakwenzeka ngenxa yezici zesakhiwo.
Izinzuzo ze-turbocharger zibonakala ngokushesha:
- ukwakheka okusheshayo kokucindezela nokusabela kwenjini;
- ukuqeda isidingo sokuxhuma ohlelweni lokugcoba;
- elula futhi evumelana nezimo ukukhululwa layout;
- akukho ukulahlekelwa ukushisa.
Ngakolunye uhlangothi, uhlelo olunjalo alunazo izithiyo:
- ubuchwepheshe obubizayo;
- ukupholisa okuhlukene okuphoqelekile;
- ukwanda kwesisindo senjini.
