Nkọwa nke engines BMW M50B20 na M50B20TU
Usoro M50 gụnyere engines nwere ikike cylinder nke 2, 2.5, 3 na 3.2 lita. The kasị ewu ewu engines bụ M50B20 na a kpomkwem mbugharị nke 1.91 lita. Emepụtara injin ahụ ka ọ bụrụ nnọchi maka injin M20B20 ochie. Ihe kachasị mma ya ma e jiri ya tụnyere ndị bu ya ụzọ bụ ngọngọ nwere 6 cylinders, nke ọ bụla nwere valvụ 4. Isi cylinder ahụ nwetakwara camshafts abụọ na ndị na-akwụ ụgwọ hydraulic, n'ihi na ọ dị mkpa iji dozie nkwụsị nke valve mgbe 10-20 puku kilomita kwụsịrị.
The BMW M50B20 na M50B20TU na-eji camshafts na a na-adọ nke 240/228, oriri valves na a dayameta nke 33 mm, na iyuzucha valves na a dayameta nke 27 mm. Enwekwara nnukwu ihe oriri rọba arụnyere ebe a, nke na-enyere aka ibelata ibu ikpeazụ nke injin ahụ; emezila atụmatụ ya ma e jiri ya tụnyere ndị bu ya ụzọ na ezinụlọ M20.
Ọzọkwa, M50B20 na-eji a pụrụ ịdabere yinye mbanye kama a belt mbanye, nke ọrụ ndụ bụ 250 puku kilomita. Nke a pụtara na ndị nwe ya nwere ike chefuo nsogbu nke mgbaji belt na mgbụsị akwụkwọ nke valves. Ọzọkwa, injin combustion n'ime na-eji usoro mgbanye eletrọnịkị; kama nkesa, etinyere eriri mgbanye ọkụ, piston ọhụrụ, na mkpanaka njikọ dị fechaa.
N'afọ 1992, a gbanwere engine M50B20 na usoro Vanos pụrụ iche. Akpọrọ ya M50B20TU. Usoro a na-enye njikwa ike nke camshafts, ya bụ, na-agbanwe oge valvụ. N'ihi teknụzụ a, eserese nke paramita torque na-adị ire ụtọ, na ntinye moto na-esikwa ike n'akụkụ niile nke ọrụ ya. Nke ahụ bụ, na engine M50B20TU na obere na elu na-agba ọsọ, torque ga-adị elu karịa na M50B20, nke ga-eme ka ike (osooso) nke ụgbọ ala na-enye ohere, na tiori, ịzọpụta mmanụ ụgbọala. N'agbanyeghị ọsọ ntụgharị crankshaft, injin ahụ na-aghọwanye akụ na ụba na enyi na gburugburu ebe obibi, na nke kachasị mkpa, dị ike karị.
Enwere ọtụtụ sistemụ VANOS: Mono na Double. M50B20 na-eji usoro VANOS mono na-emekarị na oriri, nke na-agbanwe usoro mmeghe nke valves oriri. N'ezie, teknụzụ a bụ analog nke VTEC a ma ama na i-VTEC sitere na HONDA (onye nrụpụta ọ bụla nwere aha nke ya maka teknụzụ a).
N'ụzọ doro anya, iji VANOS na M50B20TU mee ka o kwe omume ịgbanwe oke torque ka ọ bụrụ obere ọsọ - ruo 4200 rpm (4900 rpm na M50B20 na-enweghị usoro VANOS).
Ya mere, 2-liter engine nke ezinụlọ M50 natara 2 mgbanwe:
- Ọdịiche dị mkpa na-enweghị sistemụ Vanos nwere oke mkpakọ nke 10.5, 150 hp. na torque nke 190 Nm na 4700 rpm.
- Site na sistemụ Vanos, camshaft ọhụrụ. N'ebe a, a na-ebuli oke mkpakọ ruo 11, ike ahụ bụ otu - 150 hp. na 4900 rpm; torque - 190 Nm na 4200 rpm.
Ọ bụrụ na ịhọrọ n'etiti nhọrọ abụọ, mgbe ahụ nke abụọ ka mma. Site n'ịdị na-eme ka torque dị ala, ọkara na nnukwu ọsọ ọsọ, injin ahụ na-agba ọsọ na akụ na ụba ma kwụsie ike karị, ụgbọ ala ahụ na-aghọwanye ike ma na-anabata pedal gas.
Na-atụgharị
Engines na a cylinder ikike nke 2 lita enweghị ike dị elu a priori, ya mere M50B20 nwe mgbe na-agbalị imeziwanye ha. Enwere ụzọ isi tinye ike inyinya na-enweghị ndụ ọrụ.
Nhọrọ dị mfe bụ ịzụta moto M50B25 maka Swap. Ọ dabara nke ọma dị ka nnọchi dị irè na ụgbọ ala nwere M50B20 ma dịkwa ike karịa ụdị 2-liter site na 42 hp. Na mgbakwunye, enwere ụzọ iji gbanwee M50B25 iji kwalite ike ọbụna n'ihu.
E nwekwara nhọrọ maka modifying "nwa afọ" M50B20 engine. Nke kachasị mfe bụ ịbawanye olu ya site na 2 ruo 2.6 lita. Iji mee nke a, ị kwesịrị ịzụta pistons si M50TUB20, ikuku eruba sensọ na crankshaft si M52B28; mkpanaka njikọ na-anọgide "nke mbụ". Ị ga-achọkwa iwere ọtụtụ ihe sitere na B50B25: throttle body, ECU na-ege ntị, onye na-ahụ maka nrụgide. Ọ bụrụ na etinyere ihe a niile n'ụzọ ziri ezi na M50B20, ike ya ga-abawanye ruo 200 hp, oke mkpakọ ga-ebili ruo 12. N'ihi ya, mmanụ nwere ọnụ ọgụgụ octane dị elu ga-achọ, yabụ naanị ị ga-ebu mmanụ mmanụ AI-98. , ma ọ bụghị mgbawa ga-eme na enweghị ike.

Ọ bụrụ na engine na-onwem na Vanos usoro, a ga-ahọrọ injectors site na M50B25, njikọ mkpara si M52B28.
Mgbanwe ndị e mere ga-abawanye ikike cylinder - ihe ga-esi na ya pụta ga-abụ ihe fọrọ nke nta ka ọ bụrụ M50B28 zuru oke, mana iji kpughee ikike ya zuru oke, ọ dị mkpa iji wụnye valvụ trotul na ihe oriri site na M50B25, egwuregwu nha nha nha ogologo, gbasaa na gbanwee ihe oriri nke isi cylinder na ọdụ ụgbọ mmiri (porting).

Nsogbu
Ma ọ bụ ezie na engine M50B20 nwere ogologo ndụ ọrụ, ọ nwere nsogbu ụfọdụ:
- Ikpo oke ọkụ. Njiri mara nke fọrọ nke nta niile esịtidem combustion engines na index M. The unit siri ike anabataghị, ya mere gafere ọrụ okpomọkụ (90 degrees) kwesịrị ime ka nchegbu maka ọkwọ ụgbọala. Ịkwesịrị ịlele thermostat, mgbapụta, antifirizi.
