Injini ye-BMW M54 esemgqeni - kungani i-M54B22, M54B25 kanye ne-M54B30 zithathwa njengezinjini ezihamba phambili zikaphethiloli ezinamasilinda ayisithupha?
Okuqukethwe
Akumangazi ukuthi amayunithi eBMW anokuthinta kwezemidlalo futhi aziwa ngokuqina kwawo. Kungalesi sizathu abantu abaningi bethenga izimoto kulo mkhiqizi. Umkhiqizo owawuyibhulokhi le-M54 usenayo intengo yawo.
Izici zenjini ye-M54 evela kwaBMW
Ake siqale ngomklamo ngokwawo. I-block block yenziwe nge-aluminium, njengekhanda. Kunamasilinda angu-6 ngokulandelana, kanti umthamo wokusebenza ungamalitha angu-2,2, 2,5 no-3,0. Ayikho i-turbocharger kule njini, kodwa kuneVanos ephindwe kabili. Enguqulweni encane kunazo zonke injini yayinamandla angu-170 hp, khona-ke kwakukhona inguqulo ene-192 hp. kanye 231hp Iyunithi ibifaneleka kumasegmenti amaningi e-BMW - E46, E39, kanye ne-E83, E53 ne-E85. Ikhishwe ngo-2000-2006, isabangela imizwa eminingi emihle phakathi kwabanikazi bayo ngenxa yesiko layo elihle lomsebenzi kanye nesifiso esisesilinganisweni sikaphethiloli.
I-BMW M54 kanye nomklamo wayo - Timing and Vanos
Njengoba abalandeli balolu phiko besho, empeleni akukho okuzophulwa kule njini. Ulwazi mayelana nezimoto ezinebanga elingu-500 km kanye nochungechunge lwezikhathi lwangempela luyiqiniso. Umkhiqizi uphinde wasebenzisa isistimu ye-valve eguquguqukayo ebizwa ngokuthi iVanos. Enguqulweni eyodwa, ilawula ukuvulwa kwama-valve okungenisa, futhi enguqulweni ephindwe kabili (injini ye-M000) nayo ikhipha ama-valve. Lokhu kulawula kuqinisekisa ukugeleza komthwalo okuphelele ekuthatheni nasekukhipheni ama-nifold amaningi. Kuyasiza ukwandisa i-torque, ukunciphisa inani likaphethiloli oshisiwe futhi kuthuthukise ubungane bemvelo benqubo.
Ingabe iyunithi ye-M54 inazo izinto ezimbi?
Onjiniyela bakwa-BMW basukumele phezulu futhi banikeze abashayeli ithuba lokushayela okuhle kakhulu. Lokhu kuqinisekiswa ukubuyekezwa kwabasebenzisi abajabule ngalo mklamo. Nokho, ine-drawback eyodwa okufanele ikhunjulwe - ukwanda kokusetshenziswa kwamafutha enjini. Kwabanye, lokhu kuyinto encane kakhulu, ngoba okumele ukwenze nje ukukhumbula ukuyigcwalisa njalo ngebanga elingu-1000 km. Kungase kube nezizathu ezimbili - ukugqokwa kwezigxivizo ze-valve stem kanye nomklamo wamasongo okhuhla amafutha. Ukushintsha ama-oil seals akuhlali kuqeda ngokuphelele inkinga, ngakho-ke abantu abafuna ukuqeda ngokuphelele inkinga yokushiswa kwamafutha badinga ukufaka esikhundleni samasongo.
Yini okufanele ikhunjulwe lapho usebenzisa i-M54 motor?
Ngaphambi kokuthenga, hlola ikhwalithi yamagesi okukhipha umoya - intuthu eluhlaza okwesibhakabhaka enjini ebandayo ingasho ukwanda kokusetshenziswa kwamafutha. Futhi lalela uchungechunge lwezikhathi. Ukuthi iqinile akusho ukuthi ayidingi ukushintshwa kumodeli oyibukayo. Lapho usebenzisa imoto, bheka isikhawu sokushintsha uwoyela (12-15 km), shintsha okokugcoba ngesihlungi bese usebenzisa amafutha ashiwo umenzi. Lokhu kuthinta ukusebenza kwedrayivu yesikhathi kanye nohlelo lweVanos.
Vimba i-M54 - isifinyezo
Ingabe kuwufanele ukuthenga BMW E46 noma enye imodeli nge injini M54? Uma nje ingabonisi izimpawu zokukhathala kwezinto ezibonakalayo, ikufanele ngempela! I-mileage yayo ephezulu ayibi kakhulu, ngakho-ke nezimoto ezinamamayela angaphezu kuka-400 kumitha ngeke zibe nezinkinga ngokushayela okuqhubekayo. Ngezinye izikhathi konke okudingekayo ukulungisa kancane futhi ungaqhubeka.
