Injini yakwaMercedes M273
Okuqukethwe
Injini yeMercedes-Benz M273 iyinjini kaphethiloli i-V8 eyaqala ukwethulwa ngo-2005 njengokuziphendukela kwemvelo injini M113.
Injini ye-M273 ine-aluminium cylinder block enemikhono ye-cast Silitec (i-Al-Si alloy), i-aluminium crankcase, i-crankshaft yensimbi eyakhiwe, izinduku zokuxhuma ezihlanganisiwe, umjovo olandelanayo wephethiloli, ukuphathwa kwezinjini zeBosch ME9, amakhanda e-aluminium silinda, ama-camshafts amabili ngaphezulu, i-chain drive, ama-valve amane isilinda ngasinye, ukuphindaphindeka kokudla okuguquguqukayo okwenziwe nge-aluminium-magnesium alloy, ukushintshwa kokushintshwa okuguqukayo. Injini engu-M273 yathathelwa indawo eyakwaMercedes-Benz M278 ngo-2010.

Izinkinga zenjini M273
Enye yezinkinga eziyinhloko nezithandwayo ze-M273 ukugqoka igiya lokushayela leketanga lesikhathi, okuholela ekwephulweni kwesimo se-camshafts ekhanda lesokudla (sezinjini ezenziwe ngaphambi kuka-Septhemba 2006). Ungayibona kanjani inkinga: Isibani senjini yokuhlola, Amakhodi Wenkinga Yokuhlola (i-DTCs) ayi-1200 noma angu-1208 agcinwa ophikweni lokulawula i-ME-SFI.
Izimoto ezakhiwe kusuka ngoSepthemba 2006 zinegiya lensimbi elinzima.
Ukuvuza kuka-oyela ngamapulaki ekhanda lesilinda sepulasitiki... Ezinjini zakwaMercedes-Benz I-M272 V6 kanye nama-M273 V8 akhiqizwa ngaphambi kukaJuni 2008 angathola ukuvuza kwamafutha (i-seepage) ngamapulaki ayindilinga okwandiswa kwepulasitiki ngemuva kwamakhanda esilinda.
Kwakunezinhlobo ezimbili zeziqu zosayizi abahlukahlukene:
- I-000 998 55 90: ama-plugs amancane wokunweba amancane (cishe u-2,5 cm ububanzi);
- I-000 998 56 90: ipulagi eyodwa enkulu yokwandisa (yezinjini ezingenaphampu yepayipi).
Ukulungisa lokhu, udinga ukususa ama-plugs akhona, uhlanze imbobo, bese ufaka ama-plugs amasha. Ungasebenzisi i-sealant lapho ufaka ama-plugs amasha.
NgoJuni 2008, ama-bushings amasha afakwa ekukhiqizweni, angakhonjelwe ukuvuza kukawoyela.
Ukuphuka kwesilawuli se-damper kokuphindwe kaningi kokudla (i-geometry yokudla eguquguqukayo). Ngenxa yokungeniswa okuphoqelelwe kwamagesi e-crankcase, imali engafakwa ekhabhoni ingaqongelela kokuphindaphindwayo kokudla, okuthikameza ukuhamba kwendlela yokulawula, okuholela ekuwohlokeni kwayo.
Izimpawu:
- Ayisebenzi kahle;
- Ukuphela kwamandla (ikakhulukazi ngejubane eliphansi naphakathi kwenjini)
- Ukukhanya kwamalambu okuxwayisa ngezinjini;
- Amakhodi Wenkinga Yokuhlola (i-DTCs) afana ne-P2004, P2005, P2006, P2187 ne-P2189 (kumisa amakhodi wephutha we-OBD2).
Ukushuna kwezinjini zeMercedes-Benz М273
Ukushuna kwenjini ye-M273 kuthatha izinketho zomkhathi ne-compressor (womabili amakhithi angatholakala eKleemann):
- Umkhathi. Ukufaka ama-camshafts ngesigaba sama-268, ukuphothulwa kokukhishwa, ukudla okubandayo, i-firmware eguquliwe.
- Isicindezeli. Inkampani yakwaKleemann inikela nge-compressor kit ye-M273 ngaphandle kwesidingo sokushintsha i-piston compressor ejwayelekile ngenxa yengcindezi ephansi yokunyusa. Ngokufakwa kwekhithi enjalo ungafinyelela ku-500 hp.
