BMW N57D30, N57D30S1, N57D30TOP izinjini
Ukukhiqizwa kwesizukulwane esilandelayo se-6-cylinder turbocharged diesel injini - N57 (N57D30) evela ku-Steyr Plant, yaqala ngo-2008. Ihambisana nazo zonke izindinganiso ze-Euro-5, i-N57 ithathe indawo ye-M57 ethandekayo - enikezwa ngokuphindaphindiwe emiqhudelwaneni yamazwe ngamazwe kanye neyodwa ehamba phambili kumugqa we-BMW turbodiesel.
I-N57D30 ithole i-aluminium evaliwe ye-BC, lapho i-crankshaft eyenziwe ngomgunyathi ene-piston stroke engu-90 mm (ubude bayo buyi-47 mm) ifakwe, okwenza kube lula ukufeza amalitha angu-3 wevolumu.
I-cylinder block izuze kumanduleli wayo ikhanda lesilinda le-aluminium, ngaphansi kwalo kufihlwe ama-camshaft amabili nama-valve angu-4 isilinda ngasinye. Ububanzi bama-valve endaweni yokungena nokuphumayo: 27.2 no-24.6 mm, ngokulandelana. Amavalvu anemilenze engu-5 mm ubukhulu.
Isici sesici sokushayela kwe-timing chain ku-N57 injini evuthayo yangaphakathi, njengaku-N47, ukuthi iketango litholakala ngemuva kokufakwa. Lokhu kwenzelwa ukunciphisa izingozi zabahamba ngezinyawo uma kunesimo esiphuthumayo.
Amayunithi e-N57D30 afakwe: ubuchwepheshe bokuhlinzeka ngophethiloli we-diesel - I-Common Rail 3; I-high pressure fuel futha i-CP4.1 evela e-Bosh; I-supercharger Garrett GTB2260VK 1.65 ibha (kwezinye izinguquko, amamodeli we-turbocharging kabili noma kathathu afakiwe), futhi-ke, i-intercooler.
Okunye okufakwe ku-N57D30 ama-swirl flaps, i-EGR, kanye neyunithi ye-elekthronikhi ye-Bosch ene-DDE firmware version 7.3.
Ngesikhathi esifanayo ne-6-cylinder N57, ikhophi yayo encane yakhiqizwa - i-N47 enamasilinda angu-4. Ngaphezu kokungabikho kwepheya lamasilinda, lezi zinjini zazihlukaniswa ngama-turbocharger, kanye nezinhlelo zokungenisa nokukhipha.
Kusukela ngo-2015, i-N57 ishintshwe yi-B57.

Izinzuzo nezinkinga ze-N57D30
Izinzuzo:
- Amasistimu we-Turbo
- Ujantshi Ojwayelekile
- Amandla aphezulu wokushuna
Umthengi:
- i-crankshaft damper
- Izinkinga ze-flap zokungenisa
- Ama-injection ane-piezoelectric drive
Imisindo engaphezulu ku-N57D30 ikhombisa umshini wokudambisa i-crankshaft, ovame ukwenzeka kakade kumakhilomitha ayizinkulungwane eziyi-100. Ngemva kwezinye izinkulungwane eziyikhulu, umsindo ongeyena owemvelo ngemuva kweyunithi ubonisa isidingo esingenzeka sokushintsha uchungechunge lwesikhathi. Inkinga eyengeziwe lapha ukusebenza kokudilizwa kwesikhungo samandla, ngoba idrayivu ngokwayo itholakala ngemuva. Chain resource - kuka 200 ayizinkulungwane km.
Ngokungafani namayunithi omndeni wakwa-M, ama-dampers aku-N57D30 awakwazi ukungena enjinini yangaphakathi, kodwa angambozwa kakhulu nge-coke aze ayeke ukusebenza, yingakho injini izonikeza amaphutha njalo.
I-valve ye-EGR nayo idinga ukuhlanzwa, ngoba ngokuvamile, kakade kumakhilomitha ayizinkulungwane eziyi-100, ingavalwa kahle ngokungcola. Ukuze ugweme izinkinga ezingenhla, kungcono ukumane ubeke amapulaki kuma-dampers kanye ne-EGR.
Ukuze injini isebenze ngokwanele ngokwedlulele ngemva kwalokho, kuzodingeka ukhanyise kabusha iyunithi yokulawula.
Isisetshenziswa sophephela enjinini BMW N57D30 imayelana 200 ayizinkulungwane km, kodwa ngokuvamile ngisho nangaphezulu. Ukuze iyunithi yamandla isebenze isikhathi eside ngangokunokwenzeka, akufanele wonge izinga likawoyela futhi kungcono ukusebenzisa uketshezi lobuchwepheshe olunconywe umenzi, kanye nokusevisa injini ngesikhathi esifanele futhi uyigcwalise amafutha afakazelwe. Khona-ke insiza ye-N57D30 izinjini ngokwayo ingadlula kakhulu i-300 km eshiwo umenzi.
Shintshanisa amasheya N57D30
I-N57D30s evamile (N57D30U0 kanye ne-N57D30O0) ene-turbocharger eyodwa ingafinyelela ku-300 hp ngosizo lwe-chip tuning, futhi ngepayipi eliphansi amandla abo angafinyelela ku-320 hp. Amayunithi we-N57D30T1 kuleli cala engeza ngaphezu kwe-10-15 hp. Ngendlela, ama-ICE angenhla ane-204 ne-245 hp. edume kakhulu ukushuna.
Amandla e-N57D30TOP anama-supercharger amabili anokukhanya okukodwa nje kweyunithi yokulawula kanye ne-downpipe ashunwa aze afike ku-360-380 hp.
Mhlawumbe engenasici kuwo wonke umndeni wakwa-N57 iyunithi yedizili engu-N57D30S1 enohlelo lomjovo we-Tri-Turboged, ngemva kokulungiswa kwe-chip kanye ne-downpipe, ingathuthukisa amandla afinyelela ku-440 hp. futhi 840nm.
