BMW M52B28 injini

Injini yakatanga kuiswa muna March 1995 paBMW 3-series, ine E36 index.

Pashure paizvozvo, simba chikwata akaiswa pane dzimwe mhando BMW: Z3, 3-akatevedzana E46 uye 3-akatevedzana E38. Kupera kwekugadzirwa kweinjini idzi kwakatanga muna 2001. Pakazara, 1 injini dzakaiswa muBMW mota.

M52B28 injini kugadziriswa

1. Injini yekutanga yakanyorwa M52B28 uye yakagadzirwa pakati pe1995 ne2000. Ndiyo base unit. The compression reshiyo i10.2, simba iri 193 hp. pa torque kukosha kwe280 Nm pa3950 rpm.
2. Iyo M52TUB28 inhengo yechipiri yeiyi BMW injini renji. Mhedzisiro huru ndeye kuvapo kweDouble-VANOS system pakutora uye kupera sitiroko. Iko kukosha kweiyo compression reshiyo uye simba zvachinja, uye zvakasvika 10.2 uye 193 hp. ukuwo, pa5500 rpm. Torque kukosha ndeye 280 Nm pa3500 rpm.

Unyanzvi hunhu uye dhizaini maficha einjini

Injini ine square geometry. Zviyero zvakazara 84 ne84 mm. Iyo cylinder dhayamita yakafanana neyekare chizvarwa cheinjini yeM52 mutsara. Kureba kwekumanikidza kwepiston ndeye 31,82 mm. Musoro wecylinder wakakweretwa kubva kuM50B25TU injini. Iyo modhi yemanozzles anoshandiswa muM52V28 injini ndeye 250cc. Mukutanga 1998 yakapinda kugadzirwa itsva kugadziridzwa injini, iyo yainzi M52TUB28.

Kusiyana kwayo ndiko kushandiswa kwe-cast-iron sleeves, uye panzvimbo yevanos system, kaviri vanos mechanism yakaiswa mairi. Camshaft parameters: kureba 244/228 mm, kureba 9 mm. Iine pistons uye tsvimbo dzinobatanidza. Iyo DISA inosiyana geometry exhaust manifold yakagadziridzwa zvakare.

Kekutanga mumutsara weM52, yemagetsi throttle uye inotonhorera system yakaiswa. Motokari dzese dzakaiswa mota idzi dzakagamuchira i28 index. muna 2000, injini yeM54B30 yakapinda mukugadzirwa, inova mutsivi weM52B28, iyo yakaguma muna 2001.

Injini iyi ine vanos imwe ine nikasil coating.

Kusiyana neM52B25 injini yejini, iyo bhuroka yakagadzirwa nesimbi yakakandwa, muM52B28 injini, uremu hweiyo flywheel, pamwe chete nechemberi pulley, yakagadzirirwa kuderedza torsional vibrations, zvishoma. Izvi zvinobatsira pakuti kushanda nesimba kwemotokari yose kunovandudzwa. Ukuru hwevhavha ndeye 6 mm, mukugadzirwa kwavo kune imwe cone-type spring. Iyo silinda block yeM52V28 injini yakagadzirwa nealuminium. Iyo block inosimbisa chimiro inogadzirwa neakakosha couplers uye mabhureki. Iyi dhizaini haina monolithic rigidity, izvi zvinokutendera iwe kutsiva kwakasiyana deformation kana mota ichipisa.

Mabhaudhi akagadzirirwa kusungirira majoko muM52B28 aruminiyamu injini block akareba kupfuura mabhaudhi anoshandiswa musimbi yakakandwa cylinder blocks. Oiri nozzles yeinjini, iyo vhoriyamu iri 2.8 litita, ine nzvimbo yakarurama kupfuura yakatangira.

Mazano avo anonangidzirwa pasi pepiston mune chero chinzvimbo che crankshaft. Izvo zvakakosha kuti uzive kuti kumberi uye kumashure crankshaft mavhavha ari pamagasket eiyo "Metal package" mhando. Uyewo zvisimbiso zvemafuta e crankshaft, pasina kushandisa zvitubu zvesimbi. Izvi zvakaita kuti zvikwanisike kuderedza kupera kwekukwesha nzvimbo.

Iyo piston system yeM52B28 injini ndeyemhando yepamusoro. Kuenzaniswa nejini diki, iyo B28 yemukati yekupisa injini crankshaft irefu-sitiroko, saka, mapistoni anoshandiswa nekudzikisira kureba kwekumanikidza. Pasi pepistoni ine chimiro chakatsetseka.

Dambudziko nzvimbo dzeM52B28 injini

1. Chinhu chekutanga chekucherechedza ndechekupisa. Injini kubva kuM52 dzakatevedzana, pamwe nekumisikidzwa kweinjini neiyo M50 index, iyo yakagadzirwa zvishoma kare, kazhinji inopisa. Kuti ubvise kukanganisa uku, zvinodikanwa nguva nenguva kuchenesa radiator, pamwe nekudzinga mweya kubva kune inotonhorera system, tarisa pombi, thermostat uye radiator cap.
2. Dambudziko rechipiri rinowanzoitika ndiro rinopisa mafuta. Zvinoratidzika nekuda kwekuti zvindori zvepiston zviri pasi pekuwedzera kupfeka. Muchiitiko chekukuvadza kumadziro emasilinda, zvinodikanwa kuita sleeve maitiro. Kana iwo akakwana, saka iwe unogona kungopfuura nekutsiviwa kwepiston mhete. Izvo zvinodiwawo kutarisa mamiriro evhavha, iyo inokonzera ventilation ye crankcase magasi.
3. Dambudziko rekukanganisa kunoitika kana ma hydraulic lifters akabikwa. Izvi zvinotungamirira kune chokwadi chokuti kushanda kwemadonhwe e-cylinder uye chikwata chekugadzirisa magetsi chinodzima. Mhinduro yedambudziko ndeyekutengwa kwema hydraulic lifters matsva.
4. Rambi remafuta rinovheneka pane chiridzwa. Chikonzero cheizvi chinogona kunge chiri mukombe wemafuta kana pombi yemafuta.
5. Nekumhanya mushure me150 zviuru zvemakiromita. panogona kunge paine matambudziko nevanos. Zviratidzo zvekubuda kwake kubva pakumira ndezvi: kutaridzika kwekutinhira, kudonha kwesimba uye kumhanya kwekushambira. Kuti ugadzirise mamiriro acho ezvinhu, unofanira kutenga gadziriso yeM52 injini.

Kune zvakare matambudziko nekutadza kwe crankshaft uye camshaft chinzvimbo sensors. Paunenge uchibvisa musoro wecylinder, zvingave zvakaoma kupinza kubatana. Iyo thermostat haina kunyatso kunaka uye kazhinji inotanga kudonha.

Injini yemafuta akakodzera kushandiswa muinjini iyi: 0W-30, 0W-40, 5W-30, 5W-40. Inenge yehupenyu hweinjini, nekunyatsoshanda, uye kushandiswa kwemhando yepamusoro yemafuta uye mafuta, inogona kudarika 500 zviuru zvemakiromita.

Tuning injini yekuisa BMW M52B28

Imwe yenzira dzakareruka dzekugadzirisa ndeyekutenga muteresi akanaka, akaiswa paM50B52 ICE. Mushure maizvozvi, ipa injini nemhepo inotonhora yekudyara uye camshafts kubva SD52B32, uye wobva waita general tuning yekuisa injini. Mushure mezviito izvi, paavhareji, inenge 240-250 horsepower inowanikwa. Iri simba richava rakakwana kuti rifambe zvakanaka muguta nekupfuura. Kubatsira kweiyi nzira ndeyekudhura kwakaderera.

Imwe sarudzo ndeyekuwedzera huwandu hwemasilinda kusvika 3 litita. Kuti aite izvi, unofanira kutenga crankshaft kubva M54B30. Mushure maizvozvi, piston yakajairika inoderedzwa ne 1.6 mm. Zvimwe zvinhu zvese zvinoramba zvisina kubatwa. Zvakare, kuti uvandudze maitiro emagetsi, zvinokurudzirwa kutenga uye kuisa iyo M50B25 yekutora yakawanda.

Iyo iri nyore sarudzo ndeyekuisa Garrerr GT35 turbocharger. Kuiswa kwayo kunoitwa pane stock piston system M52B28. Iko kukosha kwesimba kunogona kusvika ku400 horsepower. Kuti uite izvi, zvakakosha kugadzirisa Megasquirt, pakumanikidzwa kwe 0,7 bar.

Kuvimbika kweiyo injini yekumisikidza haina kuderera, kunyangwe nekuwedzera kukuru kwehuwandu hwesimba. Iko kukosha kwekumanikidza iyo yakajairwa piston M52B28 inogona kumira ndeye 1 bar. Izvi zvinoratidza kuti kana iwe ukaruka injini kusvika 450-500 hp, unofanira kutenga pfuti yepiston yekugadzira, iyo yekumanikidza reshiyo iri 8.5.

Compressor mafeni anogona kutenga yakakurumbira ESS compressor kits yakavakirwa paLysholm. Nezvirongwa izvi, injini yeM52B28 inokura kupfuura mazana matatu hp. ine native piston system.
