Kucatshangelwa ukuthi injini yakhiqizwa iminyaka engu-5-6 kuphela, yafakwa kumamodeli ambalwa we-BMW kuphela:

IBMW 320i E36 iyona edayisa kakhulu ngenjini engu-2 litre. Cishe 197 izinkulungwane amayunithi izimoto ezinjalo zakhiqizwa, okuyinto

BMW 320i E36

ikhuluma ngokufunwa okuphezulu kakhulu nokuthembeka kwemoto ngokwayo, kodwa futhi nenjini.

I-BMW 520i E34 cishe iyinganekwane yemboni yezimoto yaseJalimane, eyakhiqizwa kusukela ngo-1991 kuya ku-1996. Sekukonke, amakhophi acishe abe yizinkulungwane ezingama-397 akhiqizwa. Futhi nakuba imoto inesikhathi esidlule esibi eRussia (ngenxa yabantu ababeyishayela), iseyinganekwane. Namuhla kulula ukuthola lezi zimoto emigwaqweni yaseRussia, noma kunjalo, kuncane ukubukeka kwazo kwasekuqaleni okusele - kushuniwe kakhulu.

Incazelo yezinjini ze-BMW M50B20 kanye ne-M50B20TU

Uchungechunge lwe-M50 luhlanganisa izinjini ezinamandla angama-cylinder angu-2, 2.5, 3 no-3.2 amalitha. Izinjini ezaziwa kakhulu kwakuyi-M50B20 ene-displacement eqondile ye-1.91 amalitha. Injini yadalwa esikhundleni senjini ye-M20B20 ephelelwe yisikhathi. Ukuthuthukiswa kwayo okuyinhloko uma kuqhathaniswa nabanduleli bayo ibhulokhi enamasilinda angu-6, ngalinye elinama-valve angu-4. Ikhanda le-cylinder liphinde lathola ama-camshafts amabili kanye nezinxephezelo ze-hydraulic, ngenxa yokuthi isidingo sokulungisa ukucaciswa kwe-valve ngemva kwe-10-20 km eyizinkulungwane.

I-BMW M50B20 kanye ne-M50B20TU zisebenzisa ama-camshaft anesigaba esingu-240/228, ama-valve okudonsa anobubanzi obungu-33 mm, nama-valve okukhipha umoya anobubanzi obungu-27 mm. Kukhona nenqwaba yepulasitiki efakwe lapha, esiza ukwehlisa isisindo sokugcina senjini; ukwakheka kwayo sekuthuthukisiwe uma kuqhathaniswa nabandulelayo emndenini wakwaM20.

Futhi, i-M50B20 isebenzisa i-chain drive enokwethenjelwa esikhundleni se-belt drive, impilo yesevisi engamakhilomitha ayizinkulungwane ezingu-250. Lokhu kusho ukuthi abanikazi bangakhohlwa ngenkinga yokuphuka kwamabhande nokugoba okulandelayo kwama-valve. Futhi, injini yomlilo yangaphakathi isebenzisa isistimu yokuthungela ngogesi; esikhundleni sesisabalalisi, amakhoyili omlilo, amaphistoni amasha, nezinduku zokuxhuma ezingasindi zifakiwe.

Ngo-1992, injini ye-M50B20 yashintshwa ngesistimu ekhethekile ye-Vanos. Yayibizwa nge-M50B20TU. Lolu hlelo luhlinzeka ngokulawula okuguquguqukayo kwama-camshafts, okungukuthi, ukushintsha isikhathi se-valve. Ngenxa yalobu buchwepheshe, igrafu yepharamitha ye-torque iba bushelelezi, futhi i-motor thrust nayo iyazinza kuwo wonke amabanga okusebenza kwayo. Okungukuthi, ku-M50B20TU injini ngesivinini esiphansi futhi esiphezulu i-torque izoba ngaphezu kwe-M50B20, ezoqinisekisa ukuthi i-dynamics (ukusheshisa) yemoto futhi ivumele, ngokombono, ukulondoloza uphethiloli. Kungakhathaliseki ukuthi ijubane lokujikeleza kwe-crankshaft, injini iba nezomnotho futhi ivumelane nemvelo, futhi okubaluleke kakhulu, inamandla kakhulu.

Kunezinhlelo eziningana ze-VANOS: I-Mono ne-Double. I-M50B20 isebenzisa isistimu ye-mono evamile ye-VANOS ekuthatheni, eshintsha izigaba zokuvula zama-valve okungenisa. Eqinisweni, lobu buchwepheshe buyi-analogue ye-VTEC eyaziwa kakhulu ne-i-VTEC evela kwa-HONDA (umkhiqizi ngamunye unegama lakhe lalobu buchwepheshe).

Ngokwezobuchwepheshe, ukusetshenziswa kwe-VANOS ku-M50B20TU kwenze kwaba nokwenzeka ukushintsha i-torque enkulu iye kwisivinini esiphansi - ifike ku-4200 rpm (4900 rpm ku-M50B20 ngaphandle kwesistimu ye-VANOS).

Ngakho, injini ye-2-litre yomndeni we-M50 ithole ukuguqulwa oku-2:

1. Ukwehluka okuyisisekelo ngaphandle kwesistimu yeVanos enesilinganiso sokuminyanisa esingu-10.5, 150 hp. kanye ne-torque engu-190 Nm ku-4700 rpm.
2. Ngesistimu yeVanos, amakhamera amasha. Lapha isilinganiso sokucindezela siphakanyiswe saba ngu-11, amandla ayefana - 150 hp. ngo-4900 rpm; torque - 190 Nm at 4200 rpm.

Uma ukhetha phakathi kwezinketho ezimbili, okwesibili kuyancomeka. Ngokuzinzisa i-torque ngesivinini esiphansi, esimaphakathi nesiphezulu, injini igijima ngokwezomnotho futhi izinzile, futhi imoto iba namandla futhi isabela ku-pedal gas.

Ukuhlwaya

Izinjini ezinomthamo we-cylinder 2 amalitha azinawo amandla aphezulu e-priori, ngakho-ke abanikazi be-M50B20 bavame ukuzama ukuzithuthukisa. Kunezindlela zokwengeza amandla ehhashi ngaphandle kokulahlekelwa impilo yesevisi.

Inketho elula ukuthenga i-M50B25 motor ukuze ushintshe. Ifaneleka ngokugcwele njengokushintshwa okusebenzayo kwezimoto ezine-M50B20 futhi inamandla kakhulu kunenguqulo engu-2-litre ngo-42 hp. Futhi, kunezindlela zokushintsha i-M50B25 ukuze kukhuliswe amandla nakakhulu.

Kukhona futhi izinketho zokushintsha injini "yendabuko" M50B20. Okulula kakhulu ukukhuphula ivolumu yayo isuka ku-2 iye ku-2.6 amalitha. Ukuze wenze lokhu, udinga ukuthenga ama-pistons ku-M50TUB20, izinzwa zokugeleza komoya kanye ne-crankshaft kusuka ku-M52B28; izinduku zokuxhuma zihlala "zangempela". Uzodinga futhi ukuthatha izingxenye ezimbalwa ku-B50B25: umzimba we-throttle, i-ECU eshuniwe, isilawuli sokucindezela. Uma konke lokhu kufakwe kahle ku-M50B20, amandla ayo azokhula abe ngu-200 hp, isilinganiso sokucindezela sizokhuphukela ku-12. Ngakho-ke, uphethiloli onenombolo ye-octane ephakeme uzodingeka, ngakho-ke kuzodingeka ugcwalise i-AI-98 uphethiloli. , uma kungenjalo ukuqhunyiswa kuzokwenzeka futhi kulahlekelwe amandla. Ngokufaka i-gasket ewugqinsi ekhanda lesilinda, ungashayela kuphethiloli we-AI-95 ngaphandle kwezinkinga.

Uma injini ifakwe nesistimu ye-Vanos, khona-ke ama-injection kumele akhethwe ku-M50B25, izinduku zokuxhuma ezivela ku-M52B28.

Izinguquko ezenziwe zizokwandisa umthamo we-cylinder - umphumela uzoba cishe i-M50B28 egcwele, kodwa ukuze uvule amandla ayo aphelele, kuyadingeka ukufaka i-valve ye-throttle kanye nokufaka okuningi okuvela ku-M50B25, inqwaba yemidlalo elingana nobude, ukwandisa futhi shintsha i-cylinder head intake kanye namachweba wokuqeda (porting). Lezi zinguquko zizokwandisa amandla kuze kube seqophelweni eliphezulu - injini enjalo izodlula ngokuphawulekayo i-M50B25 emandleni.

Kukhona ama-stroker kits athengiswayo ezinsizeni ezifanele ezikuvumela ukuthi uthole umthamo we-cylinder 3 litres. Ukuze wenze lokhu, badinga ukuba nesithukuthezi ku-84 mm, ama-piston anezindandatho, i-crankshaft kanye nezinduku zokuxhuma ezivela ku-m54B30 ezifakiwe. I-cylinder block ngokwayo igaywe phansi ngo-1 mm. Ikhanda lesilinda kanye namalayini athathwe ku-M50B25, ama-injection angu-250 cc afakiwe, futhi ikhithi yeketango lesikhathi eliphelele lifakiwe. Zimbalwa izingxenye ezizosala zisuka ku-M50B20 eyinhloko; manje sekuyi-M50B30 Stroker enevolumu engamalitha ama-3.

Ungakwazi ukuzuza amandla amakhulu ngaphandle kokusebenzisa i-supercharger ngokufaka ama-camshafts e-Schrick 264/256, ama-injection e-S50B32, kanye ne-6-throttle intake. Lokhu kuzokuvumela ukuthi ususe cishe ama-260-270 hp enjini.

Ikhithi ye-Turbo

Indlela elula yokufaka i-turbo a 2L M50 nge-Garrett GT30 turbo kit enezinzwa ze-MAP, i-turbo manifold, ama-wideband lambda probes, ama-injection okusebenza angu-440cc, ukungena okugcwele kanye ne-exhaust. Uzodinga futhi i-firmware ekhethekile ukuze zonke lezi zingxenye zisebenze kahle. Ekuphumeni, amandla azokhuphuka afike ku-300 hp, futhi lokhu kuseqenjini le-stock piston.

Ungakwazi futhi ukufaka ama-injection angu-550cc kanye ne-Garett GT35 turbo, esikhundleni samapistoni asefekthri ufake ama-CP Pistons, futhi ufake izinti ezintsha zokuxhuma namabhawodi e-APR. Lokhu kuzokuvumela ukuthi ususe i-400+ hp.

Izinkinga

Futhi nakuba injini ye-M50B20 inokuphila okude kwenkonzo, inezinkinga ezithile:

1. Ukushisa ngokweqile. Isici sazo zonke izinjini ezivuthayo zangaphakathi ezinenkomba M. Iyunithi inzima ukubekezelela, ngakho-ke ukudlula izinga lokushisa lokusebenza (ama-90 degrees) kufanele kubangele ukukhathazeka kumshayeli. Udinga ukuhlola i-thermostat, iphampu, i-antifreeze. Ukushisa ngokweqile kungase kubangelwe ukuba khona kwamaphakethe omoya ohlelweni lokupholisa.
2. Ukuxazulula inkinga okubangelwa ukuphuka kwama-injection, amakhoyili okubasa, ama-spark plug.
3. Isistimu ye-vanos. Imvamisa, abanikazi bezinjini abanalobu buchwepheshe bakhononda ngokugwedla ekhanda lesilinda, isivinini esintantayo, nokuncipha kwamandla. Kuzodingeka uthenge ikhithi yokulungisa i-Vanos M50.
4. Ukubhukuda rev. Yonke into ijwayelekile lapha: i-valve yomoya engasebenzi ephukile noma inzwa yokuma kwe-throttle. Ngokuvamile ixazululwa ngokuhlanza injini kanye ne-damper ngokwayo.
5. Imfucuza yamafutha. Ngenxa yokuguga kwemvelo yenjini iM50B20, ikwazi ukusebenzisa ilitha elingu-1 ngebanga lika-1000 km. Ukulungiswa kabusha okukhulu kungase kuxazulule inkinga okwesikhashana noma kungayixazululi nhlobo, ngakho-ke uzomane wengeze amafutha. Futhi, i-gasket yekhava ye-valve ingase ivuze lapha, futhi uwoyela ungavuza ngisho ne-dipstick.
6. Ithangi lokunweba le-antifreeze lingase liqhekeke ngokuhamba kwesikhathi - into epholile izovuza emfantwini.

Lezi zinkinga zenzeka ezinjinini ezisetshenzisiwe, kodwa lokhu kuyinto evamile ngokuphelele. Naphezu kwakho konke, izinjini ze-M50 zithembeke kakhulu. Lezi ngokuvamile izinjini ezidumile, eziphakathi kwezingcono kakhulu neziphumelela kakhulu kuzo zonke izinjini ezivuthayo ezidalwe ukukhathazeka kweJalimane. Azinawo amaphutha okuklama, futhi izinkinga eziphakamayo zihlobene kakhulu nokuguga noma ukusebenza okungafanele.

Iqala injini ye-BMW 5 E34 m50b20

Ngokulungiswa okufanele nokufika ngesikhathi kanye nokusetshenziswa kwekhwalithi ephezulu neyokuqala, impilo yenjini idlula amakhilomitha ayizinkulungwane ezingama-300-400. Idume ngokuba ngabantu abangaphezu kwesigidi, kodwa isalelwe yi-1 million km. kungenzeka kuphela ngesevisi ephelele.

Izinjini zenkontileka

Futhi nakuba izinjini zokugcina zangaphakathi ezivuthayo zaphuma emgqeni womhlangano ngo-1994, namuhla zisasetshenziswa, futhi izinjini zenkontileka zitholakala kalula ezindaweni ezifanele. Intengo yabo incike kumakhilomitha, isimo, okunamathiselwe, kanye nonyaka wokukhiqiza.

Amanani ahluka - kusuka kuma-ruble ayizinkulungwane ezingu-25 kuya ku-70; Intengo ejwayelekile ingama-ruble angama-50000. Nazi izithombe-skrini ezivela kuzinsiza ezifanele.

Ngemali encane ungathenga injini futhi uyifake emotweni yakho uma kunesidingo.

isiphetho

Izimoto ezisekelwe ku-BMW M50B20 kanye ne-M50B20TU yezinjini ezivuthayo zangaphakathi azinconywa ukuthi zithengwe ngesizathu esilula - impilo yabo yesevisi iphelile. Uma ukhetha i-BMW ngokusekelwe kubo, lungele ukutshala imali ekulungiseni. Kodwa-ke, uma kucatshangelwa impilo enkulu yesevisi yenjini, amamodeli ane-mileage eyizinkulungwane ezingu-200 km angakwazi ukuhamba ngenani elifanayo, kodwa lokhu akuqedi isidingo somsebenzi wokulungisa omncane noma ophakathi.
