BMW N46B20 injini

Mbiri ya injini za BMW imayamba kale isanayambike zaka za m'ma 21. Injini ya N46B20 nayonso, ndi yachikale yapaintaneti yamasilinda anayi, yopangidwa bwino kwambiri ndi a Bavaria. Chiyambi cha injini iyi ndi chiyambi cha 60s m'zaka za m'ma 10, pamene kuwala moona chosintha injini wotchedwa MXNUMX. Zosiyanitsa zazikulu zagawoli ndi:

• kugwiritsa ntchito osati chitsulo choponyedwa, komanso aluminium kuti muchepetse kulemera kwa injini;
• "zosiyanasiyana" mathirakiti kudya ndi utsi pa mbali zosiyanasiyana za galimoto;
• malo a injini kuyaka mkati mu chipinda injini ndi otsetsereka 30 madigiri.

Motor M10 wakhala mmodzi wa trendsetters kwa buku "yapakatikati" (mpaka malita 2 - M43) ndi dzuwa mkulu. Kuyambira pamenepo, mzere wa injini zamphamvu zapamzere, zomwe zili ndi mitundu yambiri ya BMW, zimayamba. Wapadera m'makhalidwe ake, panthawiyo, injiniyo inali yabwino kwambiri.

Koma Bavaria sanali okwanira, ndi ungwiro chibadidwe awo, anapitiriza kusintha bwino injini kale bwino. Osawopa kuyesera ndi kuyesetsa "zabwino", mitundu yambiri ya injini ya M10 idapangidwa, onse amasiyana mu voliyumu (kuyambira 1.5 mpaka 2.0 malita) ndi machitidwe amafuta (carburetor imodzi, carburetors wapawiri, jekeseni wamakina).

Kuphatikiza apo, a Bavaria, popeza analibe nthawi yokwanira yosewera ndi injini iyi, adaganiza zosintha mutu wa silinda mwa kuwonjezera magawo otaya a njira zolowera / zotulutsira. Kenako mutu wa silinda wokhala ndi ma camshaft awiri unagwiritsidwa ntchito, komabe, malinga ndi okonzawo, chisankhochi sichinadzilungamitse kwathunthu ndipo sichinapite kukupanga.

Anaganiza zosankha injini ya in-cylinder yomwe ili ndi camshaft imodzi yokhala ndi ma valve awiri pa silinda imodzi. Kuchokera bukuli, akatswiri adatha kuchotsa mpaka 110 hp.

M'tsogolo, mndandanda wa injini "M" anapitiriza kusintha, zomwe zinachititsa angapo mayunitsi atsopano, iwo analandira zizindikiro zotsatirazi: M31, M43, M64, M75. Ma motors onsewa adapangidwa ndikupangidwa pa block ya silinda ya M10, izi zidapitilira mpaka 1980. Kenako, M10 m'malo injini M40, umalimbana kwambiri maulendo wamba kuposa mipikisano liwiro. Kusiyana kwakukulu kuchokera ku M10 ndi lamba, m'malo mwa unyolo pamakina anthawi. Kuphatikiza apo, chipika cha silinda chinachotsa "zilonda" zina. Mphamvu za injini zopangidwa pa M40 sizinachuluke kwambiri, zotsatira zake zinali 116 hp. Pofika 1994, injini ya M40 inapita ku injini yatsopano - M43. Kuchokera pamalingaliro a mapangidwe a chipika cha silinda, palibe kusintha kochuluka, popeza zambiri zamakono zamakono zakhudza machitidwe okonda zachilengedwe ndi odalirika, mphamvu ya injini yakhala yofanana - 116 hp.

Mbiri ya chilengedwe cha galimoto, kuchokera N42 kuti N46

Chifukwa chakuti simungathe kufotokoza mbiri yonse yayitali komanso yolemera ya injini zamasilinda anayi mwachidule mwachidule, tiyeni tipitirire ku kusiyana kwakukulu pakati pa injini za N42 ndi N46. Yotsirizirayi ndi yosangalatsa kwambiri kwa ife, chifukwa idapangidwa mpaka 2013, zomwe zikutanthauza kuti magalimoto ambiri omwe ali ndi mphamvuyi akuyenda m'madera a Russian Federation ndi CIS. Tiyeni tiwone kusiyana pakati pa N46 ndi omwe adatsogolera N42.

Chifukwa chake, ICE idalemba N42 (ndi mitundu yake N43, N45) mu 2001 idalowa m'malo mwa M43. Kusiyana kwakukulu kwaukadaulo pakati pa injini yatsopano ndi M43 kunali mawonekedwe a ma camshaft awiri pamutu wa silinda (mutu wa silinda), makina osinthira ma valve (VANOS) ndi ma valve okweza (Valvetronic). Magawo amagetsi a N42 ndi ang'onoang'ono ndipo amakhala ndi mitundu iwiri yokha - N42B18 ndi N42B20, injini zoyatsira zamkati izi zimasiyana wina ndi mnzake, m'malo mwake. Nambala 18 ndi 20 mu N42 index zikusonyeza buku la injini, 18 - 1.8 malita, 20 - 2.0 malita, mphamvu - 116 ndi 143, motero. Mitundu ya magalimoto okonzeka ndi injini izi ndi yaing'ono - yekha BMW 3-mndandanda.

Tidakonza pang'ono mbiri ya kulengedwa ndi kusinthika kwa injini zamasilinda anayi, tsopano tiyeni tipite ku ngwazi yathu yamwambowo - injini yokhala ndi index ya N46. Chigawo ichi ndi kupitiriza zomveka kwa galimoto N42. Popanga injini yoyaka mkatiyi, akatswiri a ku Bavaria adaganizira zomwe adakumana nazo pomanga gawo lapitalo, adasonkhanitsa ziwerengero zambiri ndikuperekedwa kudziko lapansi injini yakale yomweyi, koma ndikusintha kwakukulu.

Chisankho chomaliza cha fakitale chinali injini ya N46B20, yomwe inali maziko a kulengedwa kwa mitundu ina ya injini ya N46. Tiyeni tione mwatsatanetsatane woyambitsa wa mndandanda - N46B20. injini iyi akadali yemweyo "tochikale" kapangidwe - mu mzere anayi yamphamvu injini kuyaka mkati, ndi buku la malita 2. Kusiyanitsa kwakukulu ndi omwe adayambitsa:

• kamangidwe kokhazikika kokhazikika kwa crank;
• pampu ya vacuum yokonzedwanso;
• odzigudubuza opangidwa ndi zinthu zolimba kwambiri ndi mbiri yosiyana;
• kusinthidwa kamangidwe ka kusanja zitsulo;
• ECU ili ndi gawo lowongolera la Valvetronic valve.

Zithunzi za ICE BMW N46B20

Kupitiriza zomveka N42 mu mawonekedwe a injini N46B20 kunakhala wopambana kwambiri. Galimoto yatsopano idasinthidwanso kwambiri, malinga ndi ziwerengero za kukonza zomwe zidalipo kale, akatswiriwo adawongolera madera omwe ali ndi vuto mu injini, ngakhale kuti sizinali zotheka kuchotseratu "zilonda" zomwe zimapezeka mu injini za BMW. Komabe, ichi ndi chinthu chofala kwa mtundu wa BMW, koma zambiri pambuyo pake.

ICE BMW N46B20 idalandira izi:

Chaka chopanga gawo lamagetsi	Kuyambira 2004 mpaka 2012 *

Ndikoyeneranso kunena ndemanga zokhudzana ndi zomwe zasonyezedwa patebulo:

* - chaka chopanga chimasonyezedwa pamzere wa injini zozikidwa pa N46 cylinder block, pochita, injini yoyaka mkati (kusintha koyambira) N46B20O0 - mpaka 2005, ICE N46B20U1 - kuchokera 2006 mpaka 2011 kutengera chitsanzo;

** - voliyumu imawerengedwanso, injini zambiri pa chipika cha N46 ndi-lita ziwiri, koma mzerewu unalinso ndi injini ya 1.8-lita;

*** - mphamvu ndi makokedwe nawonso pafupifupi, chifukwa pamaziko a chipika N46B20, pali zosintha zambiri za injini kuyaka mkati ndi mphamvu zosiyanasiyana ndi makokedwe.

Ngati pakufunika kudziwa chizindikiro chenicheni cha injini ndi nambala yake, muyenera kudalira chithunzi pansipa.

Kudalirika ndi kusakhazikika kwa injini za BMW N46B20

Pali nthano za kudalirika kwa injini "yodziwika" ya BMW, wina amayamikira mayunitsi awa, ena amawadzudzula mopanda chifundo. Palibe lingaliro losakayikira pankhaniyi, kotero tiyeni tiwone ma motors awa potengera ziwerengero ndi kujambula kufanana koyenera.

Chifukwa chake, chimodzi mwazomwe zimayambitsa kulephera kwa mayunitsi kutengera chipika cha N46 ndikutentha kwambiri. Nkhani yokhala ndi mitu yotenthedwa ndi "makhalidwe" (mutu wa silinda) ikupitilira kuchokera ku injini zomwe zidapangidwa m'ma 80s. Pa makina okhala ndi chipika cha N46, izi sizoyipa kwambiri, koma pali chiopsezo cha kulephera kwa injini. Ndipo ngati wolowa m'malo (N42) amavutika ndi kutenthedwa nthawi zambiri, ndiye kuti zinthu zili bwino ndi N46. Kutentha kwa thermostat kumatsitsidwa, koma injini imawopabe mafuta otsika kwambiri, motero, kugwiritsa ntchito mafuta oyipa ndi mafuta agalimoto a BMW kuli ngati kufa kwina, makamaka ndi kuthamanga pafupipafupi mu "kuthamanga". Pa injini yotentha kwambiri, mutu wa silinda "umayandama" mosalephera, mipata ikuwoneka pakati pa silinda ndi mutu wa silinda, choziziritsa kukhosi chozizira chimalowa m'masilinda, ndipo galimoto "imabwera" ku likulu.

Ma motors omwe ali pa block ya N46 ali ndi makina osinthira ma valve (VANOS), iyi ndi gawo laukadaulo, ndipo ikawonongeka, kukonzanso kumatha kuwononga ndalama zambiri (mpaka ma ruble 60). Izi nthawi zambiri zimachitika pamathamanga opitilira 000 km. Pakachitika "zhora" ya mafuta, choyamba, munthu ayenera kuchimwa pa zisindikizo tsinde valavu, m'malo awo ndalama za 70 - 000 rubles, malinga ndi chitsanzo cha makina ndi utumiki.

Vutoli lisachedwe, chifukwa limakhala ndi kuwonongeka kwakukulu kwa injini!

Komanso, musaiwale za kuwotcha kosatha kwamafuta, ~ mpaka 500g yamafuta pa 1000km, kutengera momwe injini ilili. Mulingo wamafuta uyenera kuyang'aniridwa mosamala ndikuwonjezera ngati kuli kofunikira.

Wina nuance pa injini anamanga pa maziko a N46B20 - nthawi unyolo limagwirira, ndi zotsatira zake zonse. Amisiri odziwa bwino ntchito amalimbikitsa kuti aziyang'anira nthawi yomwe imathamanga pamtunda wa 90 km, makamaka kwa iwo omwe amakonda kuyendetsa, okwera odekha amayenera kulabadira izi pamathamanga opitilira 000 km. Nthawi zambiri zimachitika kuti unyolo umatambasulidwa, ndipo njira zomangirira zopangidwa ndi pulasitiki zimakhala zosagwiritsidwa ntchito. Chotsatira chake, kuchepa kwakukulu kwa machitidwe amakoka, nthawi zina, phokoso la unyolo palokha limawonjezeredwa ku izi.

Nthawi zambiri, eni ake amatha kukwiyitsidwa ndi pampu yotulutsa "thukuta". Panthawi yogwira ntchito, vutoli silimawonekera, koma pakukonzekera kwina, muyenera kumvetsera "tanki ya vacuum". Ngati ma smudges ali amphamvu, ndiye kuti muyenera kugula zida zoyambirira zokonzera mpope ndikuzikonza, ndithudi, kuchokera kwa amisiri oyenerera. Komanso, pakati pamavuto omwe nthawi zambiri amakhala osakhazikika komanso kuyambika kwa injini "kwautali", chifukwa chake ndi valavu yotulutsa mpweya wa crankcase. Iyenera kusinthidwa pamathamanga opitilira 40 - 000 km.

Masewera

BMW si galimoto yosavuta, pokonza, komanso maonekedwe ndi kuyendetsa galimoto. Kupanga mwaukali, kuyimitsidwa kokonzedwa bwino, injini yokhala ndi shelufu "yosalala" ya torque. Anthu a ku Bavaria akadali sakonda kwambiri injini za volumetric, akudandaula za kulemera kwawo kwakukulu. Kufunafuna taxiing yangwiro ndi kupanga ndi yotamandika. Pokhapokha, mwatsoka, kuyendetsa ndi kusamalira magalimoto a BMW m'mayiko a Russian Federation ndi CIS amabwera pamtengo wokongola. Ndipo zikanakhala zabwino ngati kukonza okwera mtengo sikunali kofunikira, koma izi siziri za BMW.

The nuance waukulu, vuto ndi ululu wa eni BMW zoweta ndi otsika khalidwe mafuta, nthawi zambiri kumabweretsa zambiri mutu kwa eni magalimoto akunja German. Ndipo ngati muwonjezera mafuta otsika mtengo pa izi ndi chiyembekezo cha nthawi yayitali yopumira pamagalimoto amgalimoto, mumavulazidwa kwambiri. Nthawi yosintha mafuta ndi kamodzi pa 10 km iliyonse, koma eni eni agalimoto odziwa bwino adzanena molimba mtima - kusintha 000 - 5000 km iliyonse, zidzakhala bwino! Sikoyenera kudzaza choyambirira, amaloledwa kugwiritsa ntchito mafuta ofanana, koma abwino. N7000B46 "amadya" mafuta ndi mamasukidwe akayendedwe 20W-5 ndi 30W-5 bwino, ndi voliyumu chofunika pamene m'malo adzakhala ndendende malita 40.

Ma injini a BMW amakonda kukonza pafupipafupi ndipo N46B20 ndizosiyana, ili ndi mphamvu zokwanira zoyendetsa molimba mtima m'matauni, komanso mafuta apamwamba ndi mafuta amatha kupirira katundu wanthawi yayitali "m'dera lofiira". Inde, palibe amene amalankhula za mipikisano yaitali, koma kuyenda mwaukali mumzinda kapena msewu waukulu sikuwononga injini. Chinthu chachikulu ndikuwunika kutentha!

SWAP, mgwirizano ndi kukonza

Nthawi zambiri, eni BMW, pofuna kupeza mphamvu zambiri ndi kusunga pa kukonza kapena kukonza injini panopa, amagwiritsa ntchito njira monga kusinthana injini wina. Imodzi mwa njira wamba kusinthanitsa ndi injini Japanese wa mndandanda 2JZ (pali zosintha zambiri za injini iyi). Cholinga chachikulu chosinthira injini yaku Japan ndi yachi Japan ndi:

• mphamvu zazikulu;
• kukonza zotsika mtengo komanso zopindulitsa za mota iyi;
• kudalirika kwakukulu.

Kutali ndi eni ake onse amasankha kuchitapo kanthu ngati kusinthana, chifukwa mtengo wosinthira injiniyo ndikusintha kwake kotsatira ndi pafupifupi ma ruble 200. Njira yosavuta yosinthira ndikuyika chida champhamvu kwambiri (ndikusintha kwake kotsatira) kutengera chipika cha N000, ndi N46NB46 yokhala ndi mphamvu ya 20 hp. Kusiyana pakati pa mota yotereyi ndi N170B46 kuli pachivundikiro chamutu cha silinda, makina otulutsa ndi dongosolo la ECU. Njira iyi ndi yomveka, chifukwa kugula ndi kuyika galimotoyi sikudzafuna ndalama zambiri. Kuipa kwa kusintha koteroko kumaphatikizapo "zilonda" zakale za injini za BMW. Kawirikawiri, njirayi imagwiritsidwa ntchito pamene galimoto yamakono yawonongeka ndipo kukonzanso kwakukulu kapena kusinthidwa ndi gawo la mgwirizano kumafunika.

Kukachitika kuti kukonza n'kofunika, muyenera kuyang'ana ntchito ndi akatswiri oyenerera. Kusintha galimoto ndi mgwirizano ndikufanana ndi kugula "nkhumba mu poke", chifukwa pali chiopsezo chachikulu chotenga galimoto yotentha kwambiri kapena chipangizo chokhala ndi vuto lalikulu chifukwa cha vuto logwirizana ndi zisindikizo za valve.

Kotero, ngati galimoto yanu siitenthedwa, ndipo panalibe mavuto ndi zisindikizo za valavu, ndiye kuti mukhoza kukonzanso injiniyo, koma mu utumiki wotsimikiziridwa kuchokera kwa akatswiri oyenerera!

Ngati tikambirana za injini ikukonzekera zochokera chipika N46B20, ndiye kuti si duwa. Kuwonjezeka kwakukulu kwa mphamvu (kuchokera ku 100 hp) kudzafuna ndalama zazikulu ndi kukonzanso zigawo zotsalira za galimotoyo. Ambiri, zitsanzo ndi injini pa chipika N46 kawirikawiri kuchunidwa chifukwa cha mapangidwe zovuta ndi kukwera mtengo kwa zida ikukonzekera ndi zoikamo awo. Njira yabwino kwambiri pano ndikusinthira injini kupita ku ina. Koma kuwonjezeka pang'ono kwa mphamvu sikuvulaza injinizi mwa njira iliyonse, monga momwe ambiri a eni galimoto ndi ziwerengero zosawerengeka zimatsimikiziridwa, kusintha kwakukulu ndi:

• kusintha firmware (CHIP tuning) kuti ikhale yamphamvu komanso yolinganiza;
• mwachindunji utsi unsembe popanda chothandizira converters;
• kukhazikitsa kwa fyuluta ya zero kukana ndi / kapena valavu ya throttle ya mainchesi akulu.

Magalimoto okhala ndi injini za BMW N46B20

Magalimoto ambiri a BMW anali ndi injini izi (ndi zosintha zawo), monga lamulo, magawowa adayikidwa mumitundu yamagalimoto:
