mishiinka BMW M52B28
Tusmo
Matoorka ayaa markii ugu horreysay lagu rakibay bishii Maarso 1995-kii BMW 3-taxane ah, oo leh index E36.
Intaa ka dib, cutubka korontada ayaa lagu rakibay noocyada kale ee BMW: Z3, 3-series E46 iyo 3-series E38. Dhamaadka wax-soo-saarka matooradan waxay soo bilaabatay 2001-dii. Guud ahaan, 1 matoorro ayaa lagu rakibay baabuurta BMW.
M52B28 wax ka beddelka mishiinka
- Matooradii ugu horeysay waxaa lagu calaamadeeyay M52B28 waxaana la soo saaray intii u dhaxeysay 1995 iyo 2000. Waa unugga saldhigga. Saamiga cadaadisku waa 10.2, awooduna waa 193 hp. at 280 Nm at 3950 rpm.
- M52TUB28 waa xubinta labaad ee tirada engine BMW. Farqiga ugu weyni waa joogitaanka nidaamka Double-VANOS ee qaadashada iyo istaroogga qiiqa. Qiimaha saamiga cadaadiska iyo awoodda ayaa isbeddelay, oo waxay gaadhay 10.2 iyo 193 hp. siday u kala horreeyaan, 5500 rpm. Qiyaasta wareeggu waa 280 Nm at 3500 rpm.
Tilmaamaha farsamada iyo qaababka naqshadeynta mishiinka
Matoorku waxa uu leeyahay joomatari labajibbaaran. Cabbirrada guud waa 84 by 84 mm. Dhexroor dhululubo waa la mid sidii jiilkii hore ee matoorada line M52. Dhererka cadaadiska ee piston waa 31,82 mm. Madaxa dhululubada waxa laga soo amaahday mishiinka M50B25TU. Qaabka nozzles-ka loo isticmaalo matoorada M52V28 waa 250cc. Horraantii 1998-kii, wax-ka-beddelka cusub ee engine ayaa soo galay wax soo saarka, kaas oo calaamad u ahaa M52TUB28.
Kala duwanaanshaheeda waa isticmaalka gacmo-gashi birta ah, iyo halkii laga heli lahaa nidaamka vanos, habka labajibbaaran ee vanos ayaa lagu rakibay. Qiyaasta Camshaft: dhererka 244/228 mm, dhererka 9 mm. Waxay leedahay pistons iyo ulo isku xidha. Qaybaha qiiqa qiiqa ee doorsooma DISA ayaa sidoo kale dib loo habeeyey.
Markii ugu horeysay ee khadka M52, nidaamka qaboojinta iyo qaboojinta elektarooniga ah ayaa lagu rakibay. Dhammaan baabuurta lagu rakibay matooradan waxay heleen index i28. Sannadkii 2000, mishiinka M54B30 wuxuu galay wax soo saarka, kaas oo ah kii beddelay M52B28, kaas oo isna la joojiyay 2001.
Matoorkani waxa uu leeyahay hal vanos oo leh dahaarka nikasil.
Si ka duwan cutubka matoorka M52B25, kaas oo ka samaysan bir shub ah, oo ku jira mishiinka M52B28, miisaanka duuliyaha, iyo sidoo kale jiida hore, oo loogu talagalay in lagu yareeyo gariirrada torsional, ayaa aad u yar. Tani waxay gacan ka geysaneysaa xaqiiqda ah in waxqabadka firfircoon ee baabuurka guud ahaan la hagaajiyo. Cabbirka xargaha waa 6 mm, naqshadooda waxaa ku jira hal gu' oo nooca kootada ah. Qalabka dhululubada ee mishiinka M52V28 wuxuu ka samaysan yahay aluminium. Qaab dhismeedka xoojinta xannibaadda wuxuu ka samaysan yahay lammaaneyaal gaar ah iyo dhejisyo. Naqshadani ma laha adkeyn monolithic, tani waxay kuu ogolaaneysaa inaad magdhowdo cilladaha kala duwan marka matoorku la kululeeyo.
Boolalka loogu talagalay in lagu xidho harqoodyada ku jira block engine aluminium ee M52B28 ayaa ka dheer boolasha loo isticmaalo blocks cylinders bir kabka. Mashiinnada saliidda ee mishiinka, oo muggakiisu yahay 2.8 litir, ayaa leh meel ka saxsan halkii hore.
Talooyinkoodu waxay ku jihaysan yihiin xagga hoose ee bistoonada meel kasta oo ka mid ah shafka. Waxaa habboon in la ogaado in daboolka hore iyo gadaal ee daboolka ah ay ku yaalaan gaasaska nooca "xirmada birta". Sidoo kale xirmooyinka saliidda crankshaft, iyada oo aan la isticmaalin ilo bir ah. Tani waxay suurtogal ka dhigtay in la yareeyo xidhashada meelaha wax lagu xoqo.
Nidaamka piston ee mishiinka M52B28 waa mid aad u sarreeya. Marka la barbardhigo mishiinka yar, mashiinka gubashada gudaha ee B28 waa mid dheer oo istaroog ah, sidaas darteed, pistons-yada waxaa loo isticmaalaa hoos u dhigista dhererka cadaadiska. Qeybta hoose ee pistons waxay leedahay qaab fidsan.
Meelaha dhibaatada matoorada M52B28
- Waxa ugu horreeya ee la xuso waa kulaylka. Matoorada taxanaha M52, iyo sidoo kale rakibaadda mishiinka ee M50 index, kuwaas oo la soo saaray wax yar ka hor, inta badan kulaylka. Si loo baabi'iyo cilladaan, waxaa lagama maarmaan ah in si joogto ah loo nadiifiyo raadiyaha, iyo sidoo kale in laga saaro hawada nidaamka qaboojinta, hubi bamka, heerkulbeegga iyo daboolka hiitarka.
- Dhibaatada labaad ee caadiga ah waa saliidda gubta. Waxay u muuqataa sababtoo ah xaqiiqda ah in siddooyinka piston ay ku xiran yihiin xirashada sii kordheysa. Haddii ay dhacdo in ay waxyeello u geystaan derbiyada dhululubada, waxaa lagama maarmaan ah in la fuliyo habka gacanta. Haddii ay jiraan, markaa waxaad si fudud u dhaafi kartaa beddelka fiilooyinka piston. Waxa kale oo lagama maarmaan ah in la hubiyo xaaladda waalka, kaas oo mas'uul ka ah hawo-qaadista gaaska crankcase.
- Dhibaatada ridida khaldan waxay dhacdaa marka wiishashka haydarooliga la qaboojiyo. Tani waxay keenaysaa xaqiiqda ah in waxqabadka dhululubada uu hoos u dhaco oo unugga koontaroolka elektiroonigga ah uu damiyo. Xalka dhibaatadu waa iibsashada wiishash cusub oo biyo ah.
- Nalalka saliidda ayaa ku shidmaya qaybta qalabka. Sababta tani waxay noqon kartaa koob saliid ah ama bamka saliidda.
- Iyadoo orod ka dib 150 kun oo km. waxaa laga yaabaa inay jiraan dhibaatooyin xagga vanos. Calaamadaha lagu garto ka bixistiisa joogitaanka waa: muuqaalka qulqulka, hoos u dhaca awoodda iyo xawaaraha dabaasha. Si aad u xalliso xaaladda, waxaad u baahan tahay inaad soo iibsato qalabka dayactirka ee matoorada M52.
Waxa kale oo jira dhibaatooyin ah fashilka ku yimaadda dareemaha booska crankshaft iyo camshaft. Marka la saarayo madaxa dhululubada, waxaa laga yaabaa in ay adag tahay in dunta xiriirka. Heerkulbeeggu ma aha mid tayadiisu aad u fiican tahay oo badanaa wuxuu bilaabaa inuu soo daato.
Saliida mishiinka ee ku haboon isticmaalka mishiinkan: 0W-30, 0W-40, 5W-30, 5W-40. Nolosha mashiinka qiyaasta, oo leh hawlgal taxaddar leh, iyo isticmaalka saliidaha tayada sare leh iyo shidaalka, waxay noqon kartaa in ka badan 500 kun oo km.
Ku rakibida mishiinka mashiinka BMW M52B28
Mid ka mid ah fursadaha hagaajinta ugu fudud ayaa ah in la iibsado ururiye wanaagsan, kaas oo lagu rakibay M50B52 ICE. Taas ka dib, sii mishiinka qaadashada hawo qabow iyo camshafts SD52B32, ka dibna samee hagaajin guud ee rakibaadda mishiinka. Falalkan ka dib, celcelis ahaan, qiyaastii 240-250 hooras ayaa la helayaa. Awooddani waxay ku filnaan doontaa raacitaanka raaxada ee magaalada iyo wixii ka baxsan labadaba. Faa'iidada habkani waa qiimaha jaban.
Ikhtiyaarka kale waa in la kordhiyo mugga dhululubada ilaa 3 litir. Si taas loo sameeyo, waxaad u baahan tahay inaad ka soo iibsatid shafka M54B30. Taas ka dib, piston-ka caadiga ah waa la dhimay 1.6 mm. Dhammaan walxaha kale lama taaban. Sidoo kale, si loo hagaajiyo sifooyinka awoodda, waxaa lagu talinayaa in la iibsado iyo rakibo M50B25 manifoldka qaadashada.
Doorashada ugu fudud waa in lagu rakibo garrerr GT35 turbocharger. Rakibaadda waxaa lagu fuliyaa nidaamka piston stock M52B28. Qiimaha korontadu wuxuu gaari karaa 400 hooras. Si arrintan loo sameeyo, waxaa lagama maarmaan ah in la hagaajiyo Megasquirt, cadaadiska 0,7 bar.
Kalsoonida rakibaadda matoorka ma hoos u dhacdo, inkastoo kororka weyn ee qadarka awoodda. Qiimaha cadaadiska ee piston-ka caadiga ah ee M52B28 uu u adkeysan karo waa 1 bar. Tani waxay soo jeedinaysaa in haddii aad miiqdaan mishiinka ilaa 450-500 hp, markaa waxaad u baahan tahay inaad iibsato habka piston ee been abuurka ah, saamiga cadaadiska kaas oo ah 8.5.
Taageerayaasha Compressor waxay iibsan karaan xirmooyinka kombaresarada ESS ee caanka ah oo ku saleysan Lysholm. Iyada oo goobahan, mashiinka M52B28 uu horumariyo in ka badan 300 hp. oo leh nidaamka piston-ka asalka ah.
