BMW M52B28 injini

Injini yaqala ukufakwa ngoMashi 1995 ku-BMW 3-series, ne-E36 index.

Ngemva kwalokhu, iyunithi amandla efakwe kwamanye amamodeli BMW: Z3, 3-Series E46 futhi 3-Series E38. Ukuphela kokukhiqizwa kwalezi zinjini kuqale ngo-2001. Sekukonke, kufakwe izinjini eziyi-1 ezimotweni zakwaBMW.

Injini ye-M52B28 ishintsha

1. Injini yokuqala yaqokwa ukuthi i-M52B28 futhi yakhiqizwa phakathi kuka-1995 no-2000. Iyunithi eyisisekelo. Isilinganiso sokucindezela singu-10.2, amandla angu-193 hp. netorque value engu-280 Nm ku-3950 rpm.
2. I-M52TUB28 iyilungu lesibili lalolu hlu lwenjini ye-BMW. Umehluko omkhulu ukuba khona kwesistimu ye-Double-VANOS ekuthatheni nasekukhipheni isisu. Inani lesilinganiso sokucindezela namandla kushintshile, futhi laba ngu-10.2 no-193 hp. ngokulandelana, ku-5500 rpm. I-torque engu-280 Nm ku-3500 rpm.

Izici zobuchwepheshe kanye nezici zokuklama zenjini

Injini ine-geometry eyisikwele. Ubukhulu bebonke buyi-84 x 84 mm. I-cylinder diameter iyafana neyasesizukulwaneni sangaphambili sezinjini kulayini we-M52. Ukuphakama kokucindezelwa kwepiston kungu-31,82 mm. Ikhanda lesilinda libolekwe enjinini engu-M50B25TU. Imodeli yama-injection asetshenziswa ezinjinini ze-M52V28 yi-250cc. Ekuqaleni kuka-1998 kwangena ukuguqulwa okusha kwalokhu injini, okwakubhalwe ukuthi M52TUB28.

Umehluko wawo ukusetshenziswa kwemikhono ye-cast-iron, futhi esikhundleni sesistimu ye-vanos, umshini we-vanos ophindwe kabili wafakwa kuwo. Amapharamitha weCamshaft: ubude 244/228 mm, ukuphakama 9 mm. Inama-piston kanye nezinduku zokuxhuma. I-DISA variable geometry exhaust manifold nayo iphinde yasetshenziswa.

Ngokokuqala ngqa kulayini we-M52, kufakwa i-electronic throttle kanye nesistimu yokupholisa. Zonke izimoto okufakwe kuzo lezi zinjini zithole i-i28 index. ngo-2000, injini ye-M54B30 yangena ekukhiqizeni, okuyinto eyalandela i-M52B28, eyayekwa ngo-2001.

Le njini ine-vanos eyodwa ene-nikasil coating.

Ngokungafani neyunithi yenjini ye-M52B25, ibhulokhi yayo eyenziwe ngensimbi ekhonjiwe, enjini ye-M52B28 isisindo se-flywheel, kanye ne-pulley yangaphambili eklanyelwe ukudambisa ukudlidliza kwe-torsional, incane kakhulu. Lokhu kusiza ukuthuthukisa ukusebenza okuguquguqukayo kwemoto iyonke. Ubukhulu be-valve buyi-6 mm, futhi umklamo wabo uqukethe uhlobo olulodwa lwe-cone spring. I-M52V28 injini ye-cylinder block yenziwe nge-aluminium. Isakhiwo sokuqinisa ibhulokhi senziwe ngezibopho ezikhethekile nabakaki. Lo mklamo awunakho ukuqina kwe-monolithic, okwenza kube nokwenzeka ukunxephezela ukukhubazeka okuhlukahlukene lapho i-motor ishisa.

Amabhawodi aklanyelwe ukubophela amajoka enjini ye-aluminium engu-M52B28 made kunamabhulothi asetshenziswa kumabhulokhi esilinda ensimbi. Imibhobho kawoyela yenjini, umthamo wayo ungamalitha angu-2.8, inendawo elungile kunangaphambili.

Amathiphu abo aqondiswe phansi kwamapiston kunoma iyiphi indawo ye-crankshaft. Kuyaphawuleka ukuthi ikhava ye-crankshaft yangaphambili nangemuva iku-gaskets yohlobo lwe-"Metal package". Futhi izimpawu ze-crankshaft, ngaphandle kokusetshenziswa kwemithombo yensimbi. Lokhu kwenze kwaba nokwenzeka ukunciphisa ukuguga ezindaweni zokuhlikihla.

Uhlelo lwe-piston lwenjini ye-M52B28 lusezingeni eliphezulu kakhulu. Uma kuqhathaniswa nenjini encane, i-crankshaft yenjini evuthayo yangaphakathi ye-B28 ine-stroke ende, ngakho-ke, ama-pistons asetshenziswa ngobude obuncishisiwe bokucindezela. Iphansi lama-pistons linomumo oyisicaba.

Izindawo ezinenkinga yezinjini ze-M52B28

1. Into yokuqala okufanele uyiqaphele ukushisa ngokweqile. Izinjini ezivela ochungechungeni lwe-M52, kanye nokufakwa kwenjini enenkomba ye-M50, eyakhiqizwa ngaphambi kwesikhathi, ngokuvamile ishisa kakhulu. Ukuze kuqedwe lokhu kuphazamiseka, kuyadingeka ukuhlanza i-radiator ngezikhathi ezithile, kanye nokukhipha umoya ohlelweni lokupholisa, hlola ipompo, i-thermostat ne-radiator cap.
2. Inkinga yesibili evamile i-oil burner. Kubonakala ngenxa yokuthi izindandatho ze-piston zingaphansi kokugqoka okwenyuka. Uma kwenzeka umonakalo ezindongeni zamasilinda, kuyadingeka ukwenza inqubo yomkhono. Uma ziqinile, ungakwazi ukudlula ukushintshwa kwamasongo e-piston. Kuyadingeka futhi ukubheka isimo se-valve, enesibopho sokungenisa umoya wamagesi e-crankcase.
3. Inkinga yokungaqhumi kahle kwenzeka lapho iziphakamisi zehydraulic ziphekwe. Lokhu kuholela eqinisweni lokuthi ukusebenza kwe-cylinder kwehla futhi iyunithi yokulawula i-electronic iyayivala. Isixazululo sale nkinga ukuthengwa kwama-hydraulic lifter amasha.
4. Isibani sikawoyela sikhanyisa kuphaneli yensimbi. Isizathu salokhu kungaba inkomishi kawoyela noma iphampu yamafutha.
5. With run ngemva 150 ayizinkulungwane km. kungase kube nezinkinga nge-vanos. Izimpawu zokuphuma kwakhe ekumeni yilezi: ukubonakala kokugedla, ukwehla kwamandla kanye nesivinini sokubhukuda. Ukuze ulungise lesi simo, udinga ukuthenga ikhithi yokulungisa izinjini ze-M52.

Kuphinde kube nezinkinga ngokuhluleka kwe-crankshaft ne-camshaft position sensors. Lapho ususa ikhanda le-cylinder, kungase kube nzima ukuxhuma uxhumano. I-thermostat ayiyona ikhwalithi enhle kakhulu futhi ivame ukuqala ukuvuza.

Amafutha enjini alungele ukusetshenziswa kule injini: 0W-30, 0W-40, 5W-30, 5W-40. Cishe ukuphila injini, ngokusebenza ngokucophelela, kanye nokusetshenziswa izinga okusezingeni eliphezulu amafutha kanye namafutha, kungaba ngaphezu kwezinkulungwane 500 km.

Tuning ukufakwa kwenjini BMW M52B28

Enye yezinketho ezilula kakhulu zokuthenga ukuthenga umqoqi omuhle, owafakwa ku-M50B52 ICE. Ngemuva kwalokho, nikeza injini nge-air air ebandayo kanye nama-camshafts avela ku-SD52B32, bese wenza ukulungiswa okuvamile kokufakwa kwenjini. Ngemva kwalezi zenzo, ngokwesilinganiso, cishe 240-250 amahhashi etholakala. Lawa mandla azokwanela ukuhamba ngokunethezeka kokubili edolobheni nangale kwalokho. Inzuzo yale ndlela yizindleko eziphansi.

Enye inketho ukukhulisa umthamo wamasilinda kumalitha ama-3. Ukuze wenze lokhu, udinga ukuthenga crankshaft kusuka M54B30. Ngemva kwalokho, piston ejwayelekile iyancipha ngo-1.6 mm. Zonke ezinye izakhi zihlala zingathintwa. Futhi, ukuze kuthuthukiswe izici zamandla, kunconywa ukuthi uthenge futhi ufake i-M50B25 intake manifold.

Inketho elula ukufaka i-Garrerr GT35 turbocharger. Ukufakwa kwayo kwenziwa ohlelweni lwe-stock piston M52B28. Inani lamandla lingafinyelela ku-400 horsepower. Ukuze wenze lokhu, kuyadingeka ukulungisa i-Megasquirt, ngokucindezela kwe-0,7 bar.

Ukuthembeka kokufakwa kwenjini akunciphi, naphezu kokwanda okukhulu kwenani lamandla. Ivelu yokucindezela i-piston ejwayelekile i-M52B28 engakwazi ukumelana nayo iyibha engu-1. Lokhu kusikisela ukuthi uma uphotha injini kuze kufike ku-450-500 hp, udinga ukuthenga umshini we-piston owenziwe, isilinganiso sokucindezela esingu-8.5.

Abalandeli be-Compressor bangathenga amakhithi we-compressor adumile asuselwa ku-Lysholm. Ngalezi zilungiselelo, injini ye-M52B28 ikhula ngaphezu kuka-300 hp. ngohlelo lwe-piston lwendabuko.
