Kedu otu BMW 50d tri-turbo diesel engine si arụ ọrụ?
Ọ bụrụ na ejima-turbo usoro bụ mgbakọ a maara dị ka usoro ma ọ bụ ihe yiri ya, a ga-ahụrịrị akụkụ teknụzụ nke BMW's tri-turbo, nke na-ejikọta teknụzụ abụọ ahụ. Biko mara, ọ bụrụ na ị maghị gbasara turbochargers, a na m akpọ gị oku ka ị lelee ebe a.
Kedu ka injin turbo atọ a si arụ ọrụ?
Nke mbụ, ekwesiri iburu n'uche na usoro a na-ebuwanye ibu nwere obere turbines abụọ (1 na 3 na eserese) na geometry na-agbanwe agbanwe, yana nnukwu turbocharger ọkọlọtọ (2 na eserese).

Na obere revs, n'okpuru 1500 rpm, a na-arịọ turbo mbụ (otu n'ime obere geometry abụọ dị iche iche) site na iyuzucha (ikuku ọhụrụ na-esi n'èzí pụta ka na-agafe nnukwu turbo). Ọbụlagodi na ọ naghị arụ ọrụ na oke ọsọ a). Mgbe ahụ, malite na 1500 rpm, nke ukwu na-abatakwa, n'ihi na iyuzucha ọkụ na-ezuru ugbu a iji kpoo ya. Buru n'uche na atọ turbines na-adịghị arụ ọrụ ọnụ site nnọọ mmalite nke mode, n'ihi na nke a iku ume adịghị mkpa zuru ezu maka ọrụ nke atọ compressors. N'ikpeazụ, na 2500 rpm, nke atọ nwere ike imecha malite ịrụ ọrụ ekele maka oghere nke damper (a na-akpọ uzo), nke na-enye ohere ka a na-enye gas na-ekpo ọkụ na turbocharger a (n'ihi na m na-echetara gị na ọ bụ ike na-enye gị ohere ịkwọ ụgbọala). engine). turbo bụ "ifufe" na-emepụta site na ikuku ikuku).
Site n'echiche nke ụkpụrụ ụlọ, anyị nwere ike iche na turbines 1 na 2 dị n'usoro n'usoro gbasara ibe ha, ebe turbin 1 na 3 (obere abụọ) dị n'otu.
Na mmalite, ikuku gas na-agbapụta dị oke, ya mere obere turbine na-eweghara ọkwa mbụ nke nkwalite.
Ugbua na 1500 rpm, injin ahụ na-etolite torque nke 650 Nm!
