Taxanaha M52 waa matoorada shidaalka BMW oo leh qaabayn gudaha-line ah oo ah 6 dhululubo iyo laba kamarad (DOHC).

Waxaa la soo saaray laga bilaabo 1994 ilaa 2000, laakiin 1998 waxaa jiray "cusbooneysi farsamo" (cusbooneysi farsamo), kaas oo nidaamka VANOS ee dual ah lagu soo bandhigay moodooyinka jira, kaas oo xakameynaya wakhtiga qiiqa qiiqa (nidaamka qaybinta gaaska dual). Liiska 10-ka matoorada Ward ee ugu wanaagsan 1997, 1998,1999, 2000 iyo 52, MXNUMX ayaa si joogto ah u muuqday mana ka tanaasulin boosaskooda.

Matoorada taxanaha M52 waxay heleen block aluminium ah oo dhululubo ah, oo ka duwan M50, kaas oo ka samaysan bir shub ah. Waqooyiga Ameerika, baabuurta weli waxaa lagu iibin jiray matooradan oo ku jira baloog-bireed ah. Xawaaraha sare waa 6000 rpm, mugga ugu weynna waa 2.8 litir.

Isagoo ka hadlaya cusboonaysiinta farsamada 1998, waxaa jira afar horumar oo waaweyn:

Nidaamka wakhtiga Vanos valve, kaas oo si faahfaahsan looga hadli doono mar dambe;
Kontoroolka ceejinta ee elegtarooniga ah;
Valve Qaadashada Geometry Beddelka leh ee laba-laaban (DISA);
Xadhkaha dhululubada oo dib loo habeeyay.

M52TUB20

Kani waa M52B20 wax laga beddelay, kaas oo, hagaajinta la helay awgeed, sida labada kale, ku leh soo jiidasho badan xagga revs hoose (wareega ugu sarreeya waa 700 rpm hoose). Dhererka dhululubada waa 80mm, istaroogga piston waa 66mm, cadaadiskuna waa 11:1. Volume 1991 cu. cm, awood 150 hp at 5900 rpm - sii wadida jiilalka sifooyinkaan waa la dareemi karaa. Si kastaba ha ahaatee, wareeggu waa 190 N * m, sida M52V20, laakiin 3500 rpm.

M52TUB25

Dhererka piston waa 75 mm, dhexroorka dhululubada waa 84 mm. Nooca asalka ah ee B25 2.5-litir ayaa ka sarreeya kii ka horreeyay ee awoodda - 168 hp. 5500 rpm. Nooca la beddelay, oo leh astaamo awood la mid ah, wuxuu soo saaraa 245 N * m isku mid ah 3500 rpm, halka B25 ay ku gaareen 4500 rpm.

M52TUB28

Barokaca matoorka waa 2.8 litir, istaroogga piston waa 84 mm, dhexroorka dhululubada waa 84 mm, crankshaft wuxuu leeyahay istaroog kordhay marka loo eego B25. Saamiga cadaadisku 10.2, awood 198 hp 5500 rpm, wareeg -280 N * m / 3500 rpm.

Dhibaatooyinka iyo faa'iido darrada qaabkan ICE waxay guud ahaan la mid yihiin M52B25. Liiska ugu sarreeya, wuxuu leeyahay kulayl badan, taas oo inta badan keenta cilladda habka qaybinta gaaska. Xalka kulaylka badan sida caadiga ah waa nadiifinta hiitarka, hubinta bamka, heerkulbeegga, daboolka hiitarka. Dhibaatada labaad waa isticmaalka saliidda oo ka badan inta caadiga ah. BMW, tani waa, mabda 'ahaan, dhibaato caadi ah, taas oo la xiriirta giraangiraha piston-ka ee aan xirneyn. Maqnaanshaha horumarinta derbiyada dhululubada, siddooyinka si fudud ayaa loo beddeli karaa oo saliiddu kama bixi doonto wax ka badan inta laguu qoray. Wiishashka Haydarooliga ee mishiinadan waxay "jeclaan" in ay coke, taas oo keenta in si khaldan loo rido.

Nidaamka VANOS wuxuu aad ugu nugul yahay shaqada matoorka iyo haddii ay dhacdo kacdoonno aan xasilloonayn, guud ahaan hawlgalka aan sinnayn ama hoos u dhaca awoodda, aad ayuu u daaliyaa. Si aad u xalliso, waxaad u baahan tahay inaad haysato qalabka dayactirka nidaamka.

Dareemayaasha booska camshaft ee aan la isku halayn karin ayaa inta badan sababa in mishiinku aanu bilaabin, in kasta oo dibadda wax walba ay fiican yihiin. Heerkulbeeggu wuxuu u janjeeraa inuu soo daato, guud ahaanna kheyraadku wuu ka hooseeyaa kan M50.

Faa'iidooyinka, waxaa la ogaan karaa in saddexdan matoor aysan si gaar ah ugu nugulayn tayada shidaalka. Ku hagaajintooda inta badan laguma talinayo, iyo sidoo kale iibsashada beddelaad, maadaama ay horeba u duqoobeen. Si kastaba ha ahaatee, kuwa ku adkaysta rabitaankooda, waxaa jira hab la xaqiijiyay - in lagu rakibo manifold M50B25, camshafts ka S52B32 iyo chip tuning. Hagaajinta noocan oo kale ah waxay kor u qaadi doontaa awoodda ugu badnaan 250 hp. Ikhtiyaar kale oo cad ayaa caajis ah ilaa 3 litir, oo ay la socoto iibsashada M54B30 crankshaft iyo goynta bistoonka 1.6 mm.

Ku rakibida marawaxadaha matoorada la tilmaamay waa hab dhammaystiran oo ku filan oo lagu kordhin karo tamarta. Tusaale ahaan, M52B28 oo leh marawaxadaha Garrett iyo habaynta processor-ka wanaagsan waxay soo saari doontaa ku dhawaad 400 hp. oo leh kooxda piston stock.

Hababka hagaajinta ee M52V25 ayaa xoogaa ka duwan. Halkan waxaa lagama maarmaan ah in la iibsado, marka lagu daro kala duwanaanta qaadashada ee "walaal" M50V25, sidoo kale crankshaft leh ulaha isku xira M52V28, iyo sidoo kale firmware. Camshafts iyo nidaamka qiiqa ayaa ka fiican in la dhigo S62 - la'aantood, ma soo baxayso marka la hagaajinayo. Sidaa darteed, mugga 2 litir, waxaad heli doontaa in ka badan 200 hp.

Si aad kor ugu qaaddo matoorka ugu yar ee 2-litir ah, waxaad u baahan doontaa boodh ilaa ugu badnaan 2.6 litir ama marawaxadaha. Caajis iyo habaysan, wuxuu awoodi doonaa inuu bixiyo 200 hp. Turbocharged iyadoo la kaashanayo xirmo turbo gaar ah ayaa ugu dambeyntii awood u yeelan doonta inay tuujiso 250 hp. 2 litir oo mugga shaqada ah. Qalabka Garrett waxaa lagu bedeli karaa Lysholm, kaas oo sidoo kale ku siin doona koror koronto isla xadka.
