Injini yakwaMercedes M271
Okuqukethwe
Ukukhiqizwa kwezinjini zeMercedes-Benz M271 kwaqala ngo-2002 njengenqubo esezingeni elithuthukisiwe. Ngokulandelayo, ukwakheka kwayo kwaguqulwa ngokuya ngezicelo zabathengi.
Izici ezijwayelekile zesakhiwo senjini zihlala zingashintshi:
- Amasilinda amasentimitha amane angama-82 mm abekwe kwikhredithi ye-aluminium.
- Umjovo amandla uhlelo.
- Isisindo - 167 kg.
- Ukufuduswa kwenjini - 1,6-1,8 litres (1796 cm3).
- Amafutha anconyiwe yi-AI-95.
- Amandla - 122-192 amahhashi.
- Uphethiloli ungamalitha ayi-7,3 ngebanga le-100 km.
Iphi inombolo yenjini
Inombolo yenjini engu-M271 itholakala ku-cylinder block ngakwesokudla, ku-gearbox flange.
Engine ukulungiswa
Injini iMercedes M271 isakhiqizwa kuze kube namuhla. Ngalesi sikhathi, kwenziwe ukuguqulwa okuningi. Uhlobo lwangempela oluchazwe ngenhla lubizwa nge-KE18 ML. Ngo-2003, injini ye-DE18 ML yathuthukiswa - kwavela ukuthi yayonga kakhulu ngokusetshenziswa kukaphethiloli.
Kuze kube ngo-2008, laba bekungabamele kuphela i-M271, kuze kuvele ukuguqulwa kwe-KE16 ML. Inosayizi wenjini oncishisiwe, uhlelo olunemijovo eminingi futhi ingakhulisa amandla amakhulu ngejubane eliphansi kakhulu.
Kakade ngo-2009 kwaqala ukukhiqizwa izinjini DE18 AL ukuguqulwa, lapho kwafakwa turbocharger. Ukusetshenziswa kwayo kunciphisa amazinga omsindo nokudlidliza, kungeza induduzo nobungani bemvelo. Ngasikhathi sinye, amandla amakhulu akhuphukile.

Izinkinga Nobuthakathaka
Ama-injectors angavuza emzimbeni wawo (isixhumi). Ngokuvamile kubonakala ezinjinini ezine-mileage ephezulu nasemazinga okushisa aphansi. Kulokhu, umshayeli uzozwa iphunga elinamandla likaphethiloli kule ndlwana. Ukuqeda le nkinga, kuyadingeka ukuthi ubeke esikhundleni semibhobho yesitayela esidala (eluhlaza) ngemibhobho yesitayela esisha (onsomi).
Ubuthakathaka abudlulanga i-compressor, okungukuthi, ama-bearings angaphambili we-screw shafts avame ukuhlupheka. Uphawu lokuqala lokugqokwa kwezimpahla ukukhala. Ngokusho komkhiqizi, ama-compressor awalungiseki, kodwa izingcweti zakwazi ukuthola i-analogue yaseJapane yalawa ma-bearings futhi ngokuphumelelayo esikhundleni sawo ngokufaka imvume.
Indlu yokuhlunga uwoyela ezinhlotsheni zakudala ayibanga zinkinga, ngaphandle kokuthi i-gasket yokuxhuma kubhlokhi ingavuza. Kodwa ezinguqulweni zakamuva, indawo yokuhlunga uwoyela ngasizathu simbe yaba ipulasitiki, okuyiqiniso, okubandakanya ukusonteka kwayo emazingeni okushisa aphezulu.
Njengezinjini eziningi zakwaMercedes, kunenkinga ngokuvalwa kukawoyela ngamapayipi wokungenisa umoya we-crankcase. Inkinga ixazululwa ngokufaka amasha esikhundleni samashubhu.
Uchungechunge lwesikhathi kuzo zonke izinhlobo zamamodeli zivamise ukwelula. Umthombo we-chain ushiya okuningi okufanele ufune - cishe ayizinkulungwane eziyi-100 km.
Ukushuna М271
Injini yeMercedes-Benz M271 idizayini eguquguqukayo kakhulu ukuzivumelanisa nezidingo zomnikazi wemoto. Ukukhulisa amandla, isihlungi esiphansi sokumelana sakhiwe ohlelweni futhi i-compressor pulley iyashintshwa. Inqubo iphela ngokubuyekezwa kwe-firmware.
Ezinguqulweni zakamuva, kungenzeka ukuthi ungene esikhundleni se-intercooler, exhaust ne-firmware.
