Tlhaloso ea lienjineri tsa BMW M50B20 le M50B20TU

Letoto la M50 le kenyelletsa lienjineri tse nang le matla a silindara a 2, 2.5, 3 le 3.2 lilithara. Tse tummeng ka ho fetisisa e ne e le lienjineri tsa M50B20 tse nang le molumo o nepahetseng oa lilithara tse 1.91. Enjene e entsoe e le sebaka sa enjene ea M20B20 ea khale. Ntlafatso ea eona e kholo ho feta ba pele ho eona ke block e nang le li-cylinders tse 6, e 'ngoe le e' ngoe e na le li-valve tse 4. Hlooho ea silinda e boetse e amohetse li-camshaft tse peli le li-hydraulic lifters, ka lebaka leo tlhoko ea ho lokisa li-valve ka mor'a hore lik'hilomithara tse likete tse 10-20 li felisoe.

BMW M50B20 le M50B20TU li sebelisa li-camshaft tse nang le karolo ea 240/228, li-valve tse kenang ka bophara ba 33 mm, li-valve tsa ho qeta - 27 mm. E boetse e na le lisebelisoa tse ngata tsa polasetiki ho fokotsa boima ba enjene ka kakaretso, 'me moralo oa eona o ntlafalitsoe ha o bapisoa le oa pele oa lelapa la M20.

Hape ho M50B20, ho e-na le ho khanna lebanta, ho sebelisoa mochine o ka tšeptjoang oa ketane, bophelo ba tšebeletso ea lik'hilomithara tse likete tse 250. Sena se bolela hore beng ba bona ba ka lebala ka bothata ba lebanta le robehileng le ho kobeha ha li-valve ka mor'a moo. Hape ka har'a enjene e tukang e ka hare, ho ile ha sebelisoa mokhoa oa ho khantša elektronike, sebakeng sa distributor, li-coil tse khantšang, li-pistons tse ncha le lithupa tse kopanyang leseli li ile tsa kenngoa.

Ka 1992, enjene ea M50B20 e ile ea fetoloa ka mokhoa o khethehileng oa Vanos. E ne e bitsoa M50B20TU. Sistimi ena e fana ka taolo e matla ea li-camshafts, ke hore, phetoho ea nako ea li-valve. Ka lebaka la thekenoloji ena, lebelo la liparamente tsa torque lea lekana, mochini oa enjene o boetse oa tsitsa mefuteng eohle ea ts'ebetso ea ona. Ke hore, ka mochine oa M50B20TU ka lebelo le tlaase le le phahameng, torque e tla ba e phahameng ho feta M50B20, e tla etsa bonnete ba hore matla (ho potlakisa) koloi, 'me, ka khopolo, ho boloka mafura. Ho sa tsotelehe lebelo la ho potoloha ha crankshaft, enjene e fetoha moruo le tikoloho, 'me ea bohlokoa ka ho fetisisa - e matla le ho feta.

Ho na le litsamaiso tse 'maloa tsa VANOS: Mono le Double. M50B20 e sebelisa mokhoa o tloaelehileng oa ho kenya mono-VANOS, o fetolang mekhahlelo e qalang ea li-valve tsa ho kenya. Ha e le hantle, theknoloji ena ke analogue ea VTEC e tsebahalang haholo le i-VTEC ho tloha HONDA (moetsi e mong le e mong o na le lebitso la hae bakeng sa theknoloji ena).

Ha e le hantle, tšebeliso ea VANOS ho M50B20TU e entse hore ho khonehe ho fetola torque e kholo ho ea ka lebelo le tlaase - ho fihla ho 4200 rpm (4900 rpm ho M50B20 ntle le tsamaiso ea VANOS).

Kahoo, enjene ea 2-liter ea lelapa la M50 e fumane liphetoho tse 2:

1. Phapang ea mantlha ntle le sistimi ea Vanos e nang le tekanyo ea compression ea 10.5, 150 hp. le torque ea 190 Nm ka 4700 rpm.
2. Ka sistimi ea Vanos, li-camshaft tse ncha. Mona, tekanyo ea compression e phahamisitsoe ho 11, matla a tšoana - 150 hp. lebelo la 4900 rpm; torque - 190 Nm ka 4200 rpm.

Haeba u khetha pakeng tsa likhetho tse peli, joale ea bobeli e molemo. Ka lebaka la ho tsitsisa ha torque ka lebelo le tlaase, le bohareng le le phahameng, enjene e sebetsa ka moruo le e tsitsitseng haholoanyane, 'me koloi e fetoha e matla le e arabelang ho pedal ea khase.

Tuning

Li-engines tse nang le matla a cylinder ea lilithara tse 2 ha li na matla a phahameng a priori, kahoo beng ba M50B20 hangata ba leka ho li ntlafatsa. Ho na le mekhoa ea ho eketsa matla a lipere ntle le ho lahleheloa ke sesebelisoa.

Khetho e bonolo ke ho reka koloi ea M50B25 bakeng sa Swap. E loketse ka botlalo e le phetoho e sebetsang ea likoloi tse nang le M50B20 le 2 hp e matla ho feta mofuta oa 42-litre. Hape, ho na le mekhoa ea ho fetola M50B25 ho eketsa matla a matla.

Hape ho na le dikgetho bakeng sa ho fetola "letsoalloa" M50B20 enjene. Ntho e bonolo ka ho fetisisa ke ho eketsa molumo oa eona ho tloha ho 2 ho isa ho 2.6 a etsang dilitara tse. Ho etsa sena, o hloka ho reka li-piston ho M50TUB20, li-sensor tsa moea le crankshaft - ho tloha M52B28; lithupa tse kopanyang li lula li le "letsoalloa". Hape o tla hloka ho nka likarolo tse 'maloa ho tloha B50B25: valve ea throttle, ECU e hlophisitsoeng, taolo ea khatello. Haeba sena sohle se kenngoa ka nepo M50B20, joale matla a eona a tla eketseha ho 200 hp, tekanyo ea compression e tla nyolohela ho 12. Ka lebaka leo, ho tla hlokahala peterole e nang le tekanyo e phahameng ea octane, kahoo ke peterole ea AI-98 feela e tla tlameha ho tlatsoa. , ho seng joalo ho tla phatloha le matla a theohe. Ka ho kenya gasket e teteaneng holim'a hlooho ea cylinder, u ka boela ua khanna ka peterole ea AI-95 ntle le mathata.

Haeba enjene e na le tsamaiso ea Vanos, joale li-nozzles li lokela ho khethoa ho tloha M50B25, lithupa tse kopanyang ho tloha M52B28.

Liphetoho tse entsoeng li tla phahamisa bokhoni ba li-cylinders - sephetho e tla ba M50B28 e batlang e tletse, empa ho bula bokhoni ba eona bo feletseng, ho hlokahala ho kenya valve ea throttle le ho kenya mefuta e mengata ho tloha M50B25, lipapali tse lekanang le lipapali. , atolosa le ho fetola likanale tse kenang le tsa ho tsoa tsa hlooho ea cylinder (porting). Liphetoho tsena li tla eketsa matla ka hohle kamoo ho ka khonehang - motlakase o joalo o tla feta matla a M50B25 haholo.

Ho rekisoa mehloling e amehang ho na le li-stroker kits tse u lumellang hore u fumane molumo oa cylinder ea lilithara tse 3. Ho etsa sena, ba lokela ho boreha ho fihlela ho 84 mm, lipiston tse nang le mehele, crankshaft le lithupa tsa ho kopanya ho tloha M54B30 li lokela ho kenngoa. Silinda block ka boeona e theohile ka 1 mm. Hlooho ea li-cylinder le li-liner li nkiloe ho M50B25, li-injection tsa 250 cc li kenngoa, sete e feletseng ea liketane tsa nako. Ho tla ba le likarolo tse 'maloa tse setseng ho tloha ho M50B20 e kholo, joale e tla ba M50B30 Stroker e nang le boholo ba 3 litres.

U ka fumana matla a mangata ntle le ho sebelisa supercharger ka ho kenya li-camshaft tsa Schrick 264/256, li-nozzles tse tsoang ho S50B32, ho kenngoa ha 6-throttle. Sena se tla u lumella ho tlosa hoo e ka bang 260-270 hp ho tloha enjeneng.

Sesebelisoa sa Turbo

Mokhoa o bonolo oa ho turbocharge 2L M50 ke ho lekana Garrett GT30 turbo kit e nang le lisensara tsa MAP, turbo manifold, broadband lambda probes, li-injection tse phahameng tsa 440cc, ho kenngoa ka botlalo le ho qeta. U tla boela u hloke firmware e khethehileng bakeng sa likarolo tsena kaofela ho sebetsa hantle. Ka tlhahiso, matla a tla nyolohela ho 300 hp, 'me sena se sehlopheng sa li-stock piston.

U ka boela ua kenya li-injection tsa 550 cc le turbo ea Garett GT35, u nkela lipiston tsa fektheri sebaka ka CP Pistons, kenya lithupa le liboutu tse ncha tsa APR. Sena se tla tlosa 400+ hp.

Mathata

Le hoja enjene ea M50B20 e na le lisebelisoa tse telele, e na le mathata a mang:

1. Ho chesa haholo. Ke tšobotsi ea hoo e batlang e le lienjineri tsohle tse tukang tse ka hare tse nang le index ea M. Sehlopha se thata ho mamella, kahoo ho feta mocheso o sebetsang (90 degrees) o lokela ho etsa hore mokhanni a tšoenyehe. U hloka ho hlahloba thermostat, pompo, antifreeze.

2. Bothata bo bakoang ke li-nozzles tse robehileng, li-coil tse tukang, li-spark plugs.
3. Sistimi ea Vanos. Hangata, beng ba lienjineri tse nang le theknoloji ena ba tletleba ka ho thothomela hloohong ea cylinder, lebelo la ho sesa le ho fokotseha ha matla. U tla tlameha ho reka thepa ea ho lokisa Vanos M50.
4. Liphetoho tsa ho sesa. Ntho e 'ngoe le e' ngoe e tloaelehile mona: valve e robehileng e sa sebetseng kapa sensor ea boemo ba throttle. Hangata e rarolloa ka ho hloekisa enjene le damper ka boeona.
5. Litšila tsa oli. Ka lebaka la ho senyeha ha tlhaho ha enjene ea M50B20, ba ka "ja" litara e le 'ngoe ka 1 km. Phetoho e ka 'na ea e-ba ka nakoana kapa ea se ke ea rarolla bothata ho hang, kahoo u tlameha feela ho eketsa oli. Hape, gasket ea sekoaelo sa valve e ka lutla mona, esita le oli e ka tsoa ka har'a dipstick.
6. Tanka ea katoloso e holim'a antifreeze e ka phatloha ha nako e ntse e feta - se pholileng se tla tloha ka lepetsong.
