Izinjini BMW M62B44, M62TUB44
Okuqukethwe
Ngo-1996, uchungechunge olusha lwezinjini ze-BMW M62 zavela emakethe yomhlaba.
Enye yezinjini ezithakazelisayo kakhulu uchungechunge - eyisishiyagalombili-cylinder BMW M62B44 umthamo 4,4 amalitha. Injini yangaphambili ye-M60B40 yasebenza njengohlobo lwe-prototype yale njini yangaphakathi evuthayo.
Incazelo yenjini
Uma ubheka, khona-ke ku-M62B44 ungathola umehluko omningi kusuka ku-M60B40. Nazi ezimbalwa zazo:
- I-cylinder block ishintshile ngokuhambisana nobubanzi obusha bala masilinda.
- Kwakukhona i-crankshaft entsha eyenziwe ngensimbi, i-long-stroke, enezinsimbi eziyisithupha.
- Imingcele ye-camshafts ishintshile (isigaba 236/228, phakamisa 9/9 millimeters).
- Uchungechunge lwezikhathi lwemigqa emibili lwathathelwa indawo umugqa owodwa, nesisetshenziswa esingamakhilomitha ayizinkulungwane ezingamakhulu amabili.
- Ama-valve e-throttle abuyekeziwe futhi i-multifold intake ishintshiwe.
Kodwa izinto eziningi azikashintshi. Ngakho-ke, isibonelo, amakhanda e-cylinder M62B44 acishe afane namakhanda ayekhona kumayunithi ochungechunge lwe-M60. Okufanayo kusebenza ezindongeni zokuxhuma nama-valve (inothi: ububanzi bama-valve wokungenisa lapha ngamamilimitha angu-35, futhi ama-valve okukhipha angama-30,5 millimeters).
Ngaphezu kwenguqulo eyisisekelo yale njini, kukhona inguqulo eye yavuselelwa kwezobuchwepheshe - yathola igama elithi M62TUB44 (kukhona okunye okuhlukile kwesipelingi M62B44TU, kodwa lokhu kuyinto efanayo) futhi yavela emakethe ngo-1998. Ngesikhathi sokubuyekeza (ukubuyekeza), uhlelo lokulawula isigaba sokusabalalisa igesi lwe-VANOS lwengezwe enjinini. Ngenxa yalesi simiso, injini isebenza kahle kuzo zonke izindlela futhi idonsa kahle. Ngaphezu kwalokho, ngenxa ye-VANOS, ukusebenza kahle kuyanda futhi ukugcwaliswa kwesilinda kuyathuthukiswa. Futhi enguqulweni ebuyekeziwe yobuchwepheshe bekukhona i-throttle ye-elekthronikhi kanye nenani eliningi lokudla elinamashaneli abanzi kancane. Uhlelo lwe-Bosch DME M7,2 lwahlinzekwa njengohlelo lokulawula lwenguqulo ebuyekeziwe.
Ngaphezu kwalokho, ezinjinini ze-TU, ama-cylinder liners aqala ukwenziwa hhayi ku-nikasil njengangaphambili (i-nikasil iyingxube ekhethekile ye-nickel-silicon eyakhiwe abakhiqizi baseJalimane), kodwa kusukela ku-alusil (i-alloy equkethe cishe i-78% ye-aluminium ne-silicon engu-12%).
Uchungechunge olusha lwezinjini ze-BMW ezinokucushwa kwe-V8 - uchungechunge lwe-N62 - lwangena emakethe ngo-2001. Ekugcineni, ngemva kweminyaka embalwa, lokhu kwaholela ekumisweni kokukhiqizwa kwamayunithi afanayo, kodwa namanje angathuthuki kangako emndenini wakwa-M.

Inombolo yenjini i-M62B44 ne-M62TUB44 ingatholakala ekugoqeni, phakathi kwamakhanda e-cylinder, ngaphansi kwe-throttle. Ukuze uyibone, kufanele ususe isembozo sepulasitiki esivikelayo bese ubheka isiteji esincane engxenyeni emaphakathi yebhulokhi. Ukwenza lula ukusesha, kunconywa ukusebenzisa ithoshi. Uma ungakwazanga ukuthola inombolo ekuzameni kokuqala, kufanele ususe, ngaphezu kwe-casing, kanye ne-throttle. Ungabona futhi izinombolo zalezi zinjini "emgodini". Leli gumbi cishe alingcolile lapha, nakuba uthuli lunganqwabelana kulo.
Yiziphi izimoto okuyi-M62B44 kanye ne-M62TUB44
Injini ye-BMW M62B44 ifakwe ku:
- BMW E39 540i;
- БМВ 540i Ukuvikelwa E39;
- BMW E38 740i/740iL;
- BMW E31 840Ci.
Inguqulo ebuyekeziwe ye-BMW M62TUB44 isetshenziswe ku:
- BMW E39 540i;
- BMW E38 740i/740iL;
- I-BMW E53 X5 4.4i;
- UMorgan Aero 8;
- ILand Rover Range Rover III.
Kuyaphawuleka ukuthi "Morgan Aero 8" akuyona imoto yezemidlalo ekhiqizwa BMW, kodwa inkampani English Morgan. Futhi iLand Rover Range Rover III nayo iyimoto eyakhiwe eBrithani.
Ukungalungi kanye nezinkinga ezivamile BMW M62B44 izinjini
Kunezinkinga ezimbalwa ezicindezela ngempela abashayeli abashayela izimoto ngezinjini ezichaziwe okufanele bazigqamise:
- Injini ye-M62 iqala ukushayisa. Isizathu salokhu kungaba, isibonelo, iketango lesikhathi eleluliwe noma ibha ye-tensioner.
- Ku-M62, i-gasket yekhava ye-valve iqala ukuvuza, kanye nedamu lokupholisa. Ungakwazi ukuxazulula le nkinga ngendlela esobala - shintsha ithangi, thatha ama-gaskets amaningi kanye nepompo.
- Iyunithi yamandla ye-M62B44 iqala ukusebenza ngokungalingani nangokuzinza (lokhu kubizwa nangokuthi "isivinini esintantayo"). Ukuvela kwale nkinga kuhlotshaniswa, njengomthetho, ngokungena komoya endaweni eningi yokungena. Kungase futhi kubangelwe amaphutha ku-KVKG, izinzwa ze-throttle, amamitha okugeleza komoya. Ukungcoliswa okuvamile kwama-throttle valve nakho kungabangela isivinini esingazinzile.
Ngaphezu kwalokho, ngemva kwamakhilomitha ayizinkulungwane ezingu-250, ukusetshenziswa kwamafutha kuyanda ku-M62 (ukuxazulula le nkinga, kunconywa ukushintsha izimpawu ze-valve stem). Futhi, ngemva amakhilomitha ayizinkulungwane 250, injini mounts ingase ishiywe.
Amayunithi wamandla we-M62B44 kanye ne-M62TUB44 aklanyelwe ukusebenzisana kuphela namafutha ekhwalithi ephezulu - kungcono ukusebenzisa amabhrendi anconywe umenzi ngokwakhe. Lawa amafutha angu-0W-30, 5W-30, 0W-40 no-5W-40. Kodwa amafutha abhalwe ukuthi 10W-60 kufanele asetshenziswe ngokucophelela, ikakhulukazi ebusika - aminyene, futhi ezinyangeni ezibandayo zonyaka kungase kube nezinkinga zokuqalisa injini. Ngokuvamile, ochwepheshe abaluleki ukonga uketshezi olusebenzayo uma imoto inenjini ye-M62. Akufanele futhi ukunganaki ukugcinwa nokunakekelwa okufika ngesikhathi.
Ukuthembeka kanye nokugcinwa kwe-BMW M62B44
Injini ye-M62B44 (yombili inguqulo eyisisekelo ne-TU) enezinga eliphezulu lokuthembeka nokuphepha. Ngaphezu kwalokhu, inokudonsa okuhle kakhulu kuma-revs aphansi, nakwezinye izindlela zokusebenza. Insiza yale moto, ngokulungiswa okufanele, inganqoba ngisho nenkomba yamakhilomitha ayizinkulungwane ezingu-500.
Ngokuvamile, injini ifaneleka kokubili ukulungiswa kwendawo kanye nokukhulu. Kodwa-ke, inazo zonke izinkinga zezinjini ze-aluminium engasindi eziboshwe nge-nikasil ne-alusil. Endaweni yobungcweti, abanye baze babize ama-motor anjalo “alahlwayo”. Kuyathakazelisa ukuthi ama-alusil cylinder blocks abhekwa njengethuthuke kakhulu kune-nikasil - okungukuthi, ukuhlukahluka kwe-TU kunezinzuzo ezithile kulesi sici.
Lapho uthenga imoto esetshenzisiwe nale injini, kunconywa ukuthi uhlole injini ngokushesha futhi uqede wonke amaphutha atholakele. Ukutshalwa kwezimali okunjalo kuzokuvumela ukuthi uzizwe uqiniseka ngokwengeziwe ngemuva kwesondo.
izinketho zokushuna
Labo abafuna ukukhulisa amandla e-BMW M62TUB44 kufanele bafake kuqala inqwaba yamashaneli abanzi kule injini (isibonelo, kusukela kunguqulo eyisisekelo).
Kudingeka futhi ukufaka ama-camshafts asebenza kahle lapha (isibonelo, ngezinkomba ze-258/258), i-sport exhaust eningi futhi wenze izinguquko. Ngenxa yalokho, ungathola amandla angaba ngu-340 - lokhu kwanele kokubili idolobha kanye nomgwaqo omkhulu. Asikho isidingo sokumane ukhiphe izinjini ze-M62B44 noma i-M62TUB44 ngaphandle kwezinyathelo ezengeziwe.
Uma amandla adingekayo ku-400 horsepower, kufanele kuthengwe futhi kufakwe i-compressor kit. Kunamakhithi amaningana atholakala ezitolo eziku-inthanethi nezingaxhunyiwe ku-inthanethi alingana ne-BMW M62 piston assembly ejwayelekile, kodwa amanani awekho aphansi kakhulu. Ngaphezu kwekhithi ye-compressor, kufanele futhi kuthengwe iphampu ye-Bosch 044. Ngenxa yalokho, uma ukucindezela kwe-bar engu-0,5 kufinyelelwa, isibalo samahhashi angu-400 sizokweqa.
Indawo ebekiwe yokushuna, ngokusho kochwepheshe, inamandla amahhashi angama-500. Ngamanye amazwi, le njini inhle kakhulu ekuhloleni amandla.
Ngokuqondene ne-turbocharging, kulokhu akuyona inzuzo kakhulu ngokombono wezomnotho. Kuyoba lula kakhulu ukuthi umshayeli adlulisele kwenye imoto yohlobo olufanayo - ku-BMW M5.
