BMW N46B20 injini

Nhoroondo yeBMW injini inotanga kare kusati kwatanga kwezana remakore rechi21. Iyo N46B20 injini haina mutsauko, ndeye classic in-line mana-cylinder unit, yakagadziridzwa zvachose nemaBavarians. Mhedzisiro yeiyi mota inodzokera kumashure ekutanga kwe60s yezana ramakore rapfuura, apo mota yechokwadi yekuchinja inonzi M10 yakaona chiedza. Zvinonyanya kusiyanisa zvikamu zvechikamu ichi ndezvi:

• kushandiswa kwete chete simbi yakakandwa, asiwo aluminium kuitira kuderedza uremu injini;
• "kusiyana-siyana" kwekutora uye kupera maturakiti kumativi akasiyana emotokari;
• nzvimbo yeinjini yekupisa yemukati mukamuri yeinjini ine mutsetse we30 madhigirii.

Motokari yeM10 yava imwe yezvigadziridzo zve "medium" vhoriyamu (kusvika 2 litita - M43) uye yakanyanya kushanda zvakanaka. Kubva ipapo, mutsara wemagetsi e-in-line injini, ayo akashongedzerwa nemhando dzakawanda dzeBMW, anotanga. Yakasiyana muhunhu hwayo, panguva iyoyo, mota yakaratidza kuve yakanaka kwazvo.

Asi maBavaria akanga asina kukwana, uye nekusakwana kwavo kwekuzvarwa, vakaramba vachivandudza dhizaini yakatobudirira. Kwete kutya kuedza uye kuedza "yakanaka", misiyano yakawanda yeM10 injini yakagadzirwa, iyo yose yakasiyana muhuwandu (kubva pa 1.5 kusvika ku 2.0 litita) uye masisitimu emafuta (imwe carburetor, dual carburetors, mechanical injection).

Kupfuurirazve - zvakanyanya, maBavarians, vasina kuwana nguva yakakwana yekutamba neinjini iyi, vakafunga kuita nhanho yekuvandudza silinda yemusoro nekuwedzera kuyerera kwezvikamu zvekupinda / zvekubuda. Ipapo cylinder musoro ine camshafts mbiri yakashandiswa, zvisinei, maererano nevakagadziri, sarudzo iyi haina kunyatsozviruramisa uye haina kupinda mukugadzirwa.

Zvakasarudzwa kusarudza in-line ina-cylinder injini ine camshaft imwe yepamusoro uye mavharuvhu maviri pacylinder. Kubva pavhoriyamu iyi, mainjiniya akakwanisa kubvisa kusvika ku110 hp.

Mune ramangwana, nhevedzano yemota "M" yakaramba ichivandudza, izvo zvakaguma nehuwandu hwezvikwata zvitsva, vakagamuchira indices dzinotevera: M31, M43, M64, M75. Ese mota idzi dzakagadzirwa uye dzakagadzirwa paM10 cylinder block, izvi zvakaenderera kusvika 1980. Mushure meizvozvo, iyo M10 yakatsiva iyo M40 injini, yakanangana nenzendo dzevagari vemo pane kukurumidza kumhanya mijaho. Musiyano mukuru kubva kuM10 ibhanhire, panzvimbo yeketani mukugadzirisa nguva. Uye zvakare, iyo cylinder block yakabvisa mamwe akajairika "maronda". Simba reinjini dzakagadzirwa paM40 harina kuwedzera zvakanyanya, kubuda kwaingova 116 hp. Pakazosvika 1994, injini yeM40 yakapa nzira kune injini itsva - M43. Kubva pakuona kwekugadzirwa kwe cylinder block, hapana kuchinja kwakawanda, sezvo zvizhinji zvezvigadzirwa zvetekinoroji zvakakanganisa kushamwaridzana kwezvakatipoteredza uye kuvimbika, simba rejini rakaramba rakafanana - 116 hp.

Nhoroondo yekugadzirwa kwemotokari, kubva kuN42 kusvika kuN46

Nekuda kwekuti haugone kutsanangura iyo yose yakareba uye yakapfuma nhoroondo ye-in-line mana-cylinder injini muchidimbu, ngatienderere mberi kune mimwe misiyano pakati peN42 neN46 injini. Iyo yekupedzisira inonyanya kufadza kwatiri, nokuti yakabudiswa kusvika muna 2013, izvo zvinoreva kuti nhamba huru yemotokari dzine chikwata ichi chemagetsi inofamba munzvimbo dzeRussian Federation neCIS. Ngationgororei misiyano pakati peN46 neyakatangira N42.

Saka, iyo ICE yakaratidza N42 (uye misiyano yayo N43, N45) muna 2001 yakatsiva iyo M43. Musiyano mukuru wetekinoroji pakati peinjini nyowani neM43 yaive kutaridzika kwemacamshaft maviri mucylinder head (cylinder head), variable valve timing system (VANOS) uye mavharuvhu ekusimudza anochinja (Valvetronic). Iyo huwandu hweN42 masimba emagetsi idiki uye ine mhando mbiri chete - N42B18 uye N42B20, idzi injini dzinopisa dzemukati dzinosiyana kubva kune mumwe chete muhuwandu chete. Nhamba 18 ne20 muN42 index inoratidza huwandu hwejini, 18 - 1.8 litita, 20 - 2.0 litita, simba - 116 uye 143, maererano. Mhando yemotokari dzine injini idzi idiki - chete BMW 3-series.

Isu takarongedza nhoroondo yekusikwa uye shanduko ye-in-line-cylinder injini zvishoma, zvino ngatiendererei kune yedu gamba rechiitiko - injini ine N46 index. Iyi unit ndeyekuenderera zvine musoro kweN42 mota. Paaigadzira injini yekupisa iyi yemukati, mainjiniya eBavaria akafunga nezve ruzivo rwekuvaka chikwata chekare, akaunganidza huwandu hwehuwandu uye akauisa kupasi rose injini imwechete yekare, asi nekuchinja kwakawanda.

Sarudzo yekupedzisira yefekitori yaive N46B20 mota, ndiye akashanda sehwaro hwekusikwa kwezvimwe zvakasiyana zveN46 mota. Ngatitarisei zvakanyanya kune muvambi wenhevedzano - N46B20. Iyi mota ichiri yakafanana "yekirasi" dhizaini - in-line ina-cylinder yemukati inopisa injini, ine vhoriyamu ye2 malita. Misiyano mikuru kubva kune yakatangira:

• kunatsiridza durable crank design;
• pombi yakagadzirwazve vacuum;
• roller pushers akagadzirwa neakawanda akasimba zvinhu zvine chimiro chakasiyana;
• yakagadziridzwa dhizaini yekuenzanisa shafts;
• Iyo ECU ine yakavakirwa-mukati Valvetronic valve control module.

Zvinotsanangurwa ICE BMW N46B20

Kuenderera mberi kunonzwisisika kweN42 muchimiro cheN46B20 injini kwakave kwakabudirira zvikuru. Iyo mota nyowani yakagadziridzwa zvakanyanya, zvichibva pahuwandu hwekugadziriswa kweakatangira, mainjiniya akavandudza nzvimbo dzine dambudziko mujini, kunyangwe zvaisakwanisika kubvisa zvachose "maronda" akajairwa muBMW injini. Nekudaro, ichi chinhu chakajairika kune iyo BMW mhando, asi zvimwe pane izvo gare gare.

ICE BMW N46B20 yakagamuchira zvirevo zvinotevera:

Gore rekugadzirwa kwechikwata chemagetsi	Kubva 2004 kusvika 2012 *

Izvo zvakakoshawo kuita zvirevo maererano nedata inoratidzwa mutafura:

* - gore rekugadzira rinoratidzwa mutsara weinjini yakavakirwa paN46 cylinder block, mukuita, injini yekupisa yemukati (basic modification) N46B2.0O0 - kusvika 2005, ICE N46B20U1 - kubva 2006 kusvika 2011 zvichienderana nemuenzaniso;

** - iyo vhoriyamu zvakare yakaverengerwa, mazhinji einjini paN46 block ane maviri-lita, asi pakanga painewo 1.8-litre injini mumutsara;

*** - simba uye torque zvakare zvakaenzana, nekuti pahwaro hweN46B20 block, kune akawanda magadzirirwo einjini yekupisa yemukati ine simba rakasiyana uye torque.

Kana pane kudikanwa kwekuziva iyo chaiyo yekumaka yeinjini uye nhamba yekuzivikanwa kwayo, saka iwe unofanirwa kuvimba nedhayagiramu iri pazasi.

Kuvimbika uye kuchengetedza kweBMW N46B20 injini

Kune ngano nezve kuvimbika kwe "kuzivikanwa" injini dzeBMW, mumwe munhu anorumbidza zvikamu izvi, vamwe vanovatsiura zvisina tsitsi. Iko hakuna maonero asina kujeka pachinhu ichi, saka ngatitarisei mota idzi zvichienderana nehuwandu uye kudhirowa zvine musoro kufanana.

Saka, chimwe chezvikonzero zvinowanzoitika zvekutadza kwemauniti zvakavakirwa paN46 block kupisa. Nyaya ine yakanyanyisa uye "maitiro" misoro (cylinder head) inoenderera mberi kubva kune injini dzakagadzirwa muma80s. Pamichina ine N46 block, izvi hazvina kushata, asi kune njodzi yekutadza kweinjini. Uye kana iyo yakatangira (N42) yakatambura nekupisa kazhinji, saka zvinhu zviri nani neN46. Iyo tembiricha yekuvhura thermostat inodzikiswa, asi injini ichiri kutya mafuta emhando yakaderera, saka, kushandiswa kwemafuta akaipa uye mafuta emota dzeBMW kwakafanana nekumwe kufa, kunyanya nenhangemutange mu "racing" rhythm. Pamusoro peinjini inopisa, musoro we cylinder "unoyangarara", mapundu makuru anoonekwa pakati pevhavhavhavha uye cylinder musoro, iyo inotonhorera kubva mujasi inotonhorera inopinda mumasilinda, uye mota "inosvika" paguta guru.

Mamotor ari paN46 block ane ma variable valve timing system (VANOS), iyi inyanzvi yetekinoroji yakaoma, uye ikaputsika, kugadzirisa kunogona kuita mari yakarongeka (kusvika ku60 rubles). Izvi zvinowanzoitika pakumhanya pamusoro pe000 km. Muchiitiko che "zhora" yemafuta, kutanga kune zvose, munhu anofanira kutadza pavhavha stem seals, kutsiva kwavo kunodhura anenge 70 - 000 rubles, zvichienderana nemuenzaniso wemuchina uye basa.

Iri dambudziko harifanirwe kunonoka, nekuti iro rakazara nekukuvara kwakakomba injini!

Zvakare, usakanganwa nezvekupisa kwemafuta asingaperi, ~ kusvika ku500g yemafuta pa1000km, zvichienderana nemamiriro einjini. Chiyero chemafuta chinofanira kunyatsotariswa uye kukwidziridzwa kumusoro kana zvichidikanwa.

Imwe nuance pamainjini akavakirwa pahwaro hweN46B20 ndiyo nguva yeketani mashini, ine zvese zvinokonzeresa. Vagadziri vane ruzivo vanokurudzira kutarisa nguva yekumhanya pamusoro pe90 km, kunyanya kune avo vanoda kutyaira, vatasvi vakadzikama vanofanira kuterera kune izvi pakumhanya pamusoro pe000 km. Zvinowanzoitika kuti cheni yakatambanudzwa, uye nzira dzekumanikidza dzakagadzirwa nepurasitiki hadzigoneki. Nekuda kweizvozvo, kuderera kukuru kwehunhu hwekudhonza, mune mamwe mamiriro, ruzha rweketani pachayo rinowedzerwa kune izvi.

Kazhinji, varidzi vanogona kutsamwiswa ne "sweating" vacuum pombi. Panguva yekushanda, dambudziko iri harina kuzviratidza, asi pakugadzirisa kunotevera, iwe unofanirwa kunyatsoteerera kune "vacuum tank". Kana iyo smudges yakasimba, saka iwe unofanirwa kutenga iyo yekutanga pombi yekugadzirisa kit uye kuigadzirisa, hongu, kubva kune vanokwanisa mhizha. Zvakare, pakati pematambudziko anowanzo kugadzikana idling uye "refu" kutanga kwejini, chikonzero ndeye crankcase ventilation valve. Inofanira kuchinjwa pakumhanya pamusoro pe40 - 000 km.

Nuances

BMW haisi motokari iri nyore, zvose maererano nekugadzirisa, uyewo maererano nechitarisiko uye kutyaira. Dhizaini ine hukasha, yakanyatso kumiswa, injini ine "yakapfava" torque sherufu. VaBavaria havasati vanyanya kufarira injini dzevolumetric, vachinyunyuta pamusoro pehuremu hwavo hunorema. Iko kutsvaga kwekuita tekisi yakakwana uye kugadzira kunorumbidzwa. Chete ikozvino, zvinosuruvarisa, kutyaira uye kuchengetedza BMW mota munyika dzeRussian Federation uye CIS inouya pane yakanaka peni. Uye zvingava zvakanaka kana kugadzirisa kunodhura kwaisawanzodiwa, asi izvi hazvisi zveBMW.

Iyo huru nuance, dambudziko uye kurwadziwa kwevaridzi veBMW vepamba imafuta emhando yakaderera, kazhinji inounza kuwanda kwemusoro kune varidzi vemotokari dzekunze dzeGerman. Uye kana iwe ukawedzera mafuta akachipa kune izvi uye tarisiro yenguva refu yekudzikira mumigwagwa yemigwagwa, unowana kukuvadza kwakakomba kumota. Nguva yakarongwa yekuchinja kwemafuta kamwechete pamakiromita gumi, asi varidzi vemotokari vane ruzivo vachataura noushingi - shandura imwe neimwe 10 - 000 km, zvichangoita nani! Hazvidikanwi kuzadza iyo yepakutanga, inobvumirwa kushandisa mafuta akafanana, asi ehutano hwakanaka. N5000B7000 "inodya" mafuta ane viscosity ye46W-20 uye 5W-30 zvakanaka, uye vhoriyamu inodiwa pakutsiva ichava 5 malita chaiwo.

Injini dzeBMW dzinoda kugara dzichigadziriswa uye iyo N46B20 haina mutsauko, ine simba rakakwana rekutyaira uine chivimbo mumamiriro emudhorobha, uye nemafuta emhando yepamusoro nemafuta anogona kumira kwenguva refu mitoro "munzvimbo tsvuku". Hongu, hapana anotaura nezvemajaho marefu, asi kufambisa zvine hasha muguta kana mugwagwa mukuru hakukuvadzi injini. Chinhu chikuru ndechekutarisa kutonhora!

SAP, chibvumirano uye tuning

Kazhinji, varidzi veBMW, vachitsvaga kuwana simba rakawanda uye kuchengetedza pakugadzirisa kana kugadzirisa injini yazvino, vanoenda kune nzira yakadai sekuchinjanisa injini kune imwe. Imwe yedzakajairika sarudzo dzekuchinjana injini yeJapan ye2JZ yakatevedzana (kune zvakawanda zvinogadziriswa zveinjini iyi). Chinangwa chikuru chekutsiva injini yekuzvarwa neyeJapan ndeiyi:

• simba guru;
• isingadhuri uye inogadzira tuning yeiyi mota;
• kuvimbika kukuru.

Kure kubva kune vese varidzi vemotokari vanosarudza kutora danho rakadaro sekuchinjana, nekuti mutengo wekutsiva mota uye kugadziridza kwayo kunotevera iri munharaunda ye200 rubles. Sarudzo iri nyore yekuchinjanisa ndeyekuisa iyo yakasimba kwazvo unit (uye inozotevera tuning) zvichibva paN000 block, ndiyo N46NB46 ine simba re20 hp. Musiyano uripo pakati pemota yakadaro neN170B46 uri mune imwe silinda yemusoro kavha, exhaust system uye ECU system. Iyi sarudzo inonyanya kunzwisisika, nekuti kutenga uye kuiswa kwemota iyi hakuzodi mari yakawanda yemitengo. Izvo zvisingabatsiri zvekuchinja kwakadaro kunosanganisira aimbova "maronda" einjini dzeBMW. Kazhinji, iyi nzira inoshandiswa kune kana injini yazvino yaputsika uye kugadzirisa kukuru kana kutsiva nekontrakiti unit inodiwa.

Muchiitiko chekuti kugadziriswa kuchidikanwa, saka iwe unofanirwa kutsvaga sevhisi ine nyanzvi dzinokwanisa. Kutsiva motokari nechibvumirano chimwe kunofananidzwa nekutenga "nguruve muhombe", nokuti kune ngozi huru yekuwana motokari yakanyanyisa kana chikwata chine kupfeka kwakakomba nekuda kwedambudziko rinosangana nevhavha stem seals.

Saka, kana mota yako isina kupisa, uye pakanga pasina matambudziko nevhavha stem seals, saka iwe unogona kudzoreredza injini zvakachengeteka, asi chete mubasa rinopupurirwa kubva kune nyanzvi dzinokwanisa!

Kana tikataura nezve tuning injini yakavakirwa paN46B20 block, saka izvi hazvina kunaka. Kuwedzera kukuru kwesimba (kubva pa100 hp) kunoda mari yakakura uye kugadziridzwa kwezvakasara zvikamu zvemotokari. Kazhinji, mamodheru ane injini paN46 block haawanzo kugadziridzwa nekuda kweiyo yakaoma dhizaini uye kudhura kwakanyanya kwemakiti ekugadzirisa uye marongero awo. Mhinduro yakanakisa pano ndeyekuchinjanisa mota kune imwe. Asi kuwedzera kudiki kwesimba hakukuvadzi injini idzi munzira chero ipi zvayo, sezvo nhamba huru yevaridzi vemotokari uye nhamba dzisingagoneki dzinogutsikana, kuvandudzwa kukuru ndeku:

• kushandura firmware (CHIP tuning) kune yakasimba uye yakaenzana;
• kuisirwa kwemhepo yakananga pasina catalytic converters;
• kuiswa kwesefa ye zero kuramba uye / kana throttle valve yedhayamita yakakura.
