N55 injini - inonyanya kukosha ruzivo pamusoro pemuchina

25.11.2022 /

Iyo itsva N55 injini ndiyo yekutanga yeBMW mapatya-mupumburu turbocharged peturu injini ine Valvetronics uye yakananga mafuta jekiseni. Verenga nezve BMW matekinoroji uye N55 yakatarwa.

N55 injini - chii dhizaini yeyuniti?

Paunenge uchigadzira dhizaini yeN55 peturu injini, zvakasarudzwa kushandisa maviri pamusoro camshafts - yakavhurika uye lamellar dhizaini - ine aluminium crankcase yaive padyo nejini. Iyo crankshaft yakagadzirwa nesimbi yakakandwa uye silinda musoro wakagadzirwa nealuminium. Iyo dhizaini inosanganisirawo mavharuvhu ekutora ane dhayamita ye32,0 mm. Zvakare, mavharuvhu ekutora akazadzwa nesodium.

Iyo N55 inoshandisa twin-scroll turbocharger. Yakanga yakashongedzerwa nema screws maviri akaparadzana aitungamira magasi emhepo kune turbine. Sezvambotaurwa, musanganiswa we turbocharging neakananga mafuta jekiseni uye Valvetronic yaivewo nyowani kuN55.

Maitiro eValvetonic system inoshanda sei

Valvetronic imwe yeazvino matekinoroji anoshandiswa neBMW. Iyi isingaperi inosiyana-siyana yekusimudza valve yekusimudza, uye kushandiswa kwayo kunobvisa kukosha kwekuisa throttle.

Iyo tekinoroji inodzora huwandu hwemhepo inopihwa kupisa kune drive unit. Iko kusanganiswa kweatatu masisitimu (turbo, yakananga mafuta jekiseni uye Valvetronic) inoguma nekuvandudzika maitiro ekupisa uye yakanyanya kunatsiridza mhinduro yeinjini kana ichienzaniswa neN54.

Kusiyana kweBMW N55 powertrain

Iyo injini yekutanga yaive N55B30M0, yakatanga kugadzirwa muna 2009.

  1. Simba rayo i306 hp. pa5-800 rpm;
  2. Iyo torque ndeye 400 Nm pa1-200 rpm.
  3. Iyo drive yakaiswa paBMW mota ine 35i index.

N55 injini

Imwe vhezheni itsva yeinjini ye turbocharged ndiyo N55. Kugovera kwave kuenderera kubva 2010, uye iyo yakagadziridzwa vhezheni inopa 320 hp. pa5-800 rpm. uye 6 Nm torque pa 000-450 rpm. Mugadziri akaishandisa mumamodeli ane index 1i uye 300i.

Sarudzo N55B30O0 uye N55HP

Kutengeswa kweN55B30O0 kwakatanga muna 2011. Izvi zvakasiyana-siyana ndeye analogue yeN55, uye tekinoroji paramita ndeiyi inotevera:

  • simba 326 hp pa 5-800 rpm;
  • 450 Nm torque pa1-300 rpm.

Injini yakaiswa pamhando dzine index ye35i.

Imwe sarudzo, iyo yakatanga kugadzirwa muna 2011, ndiyo N55HP. Iine sarudzo dzinotevera:

  • simba 340 hp pa5-800 rpm. uye 6 Nm torque pa 000-450 rpm. (kupfuura 1Nm).

Yakashandiswa mumhando dzeBMW ine 35i index.

Iyo unit inowanikwawo mune yemitambo vhezheni (S55 injini inosvika ku500 hp). Zvakakodzera kutaura kuti iyo yakanyanya simba vhezheni yeM4 GTS yakashandisa jekiseni remvura.

Dhizaini misiyano pakati peBMW N54 neN55

Kutaura nezveN55, munhu haagoni kukundikana kutaura akatangira, i.e. chikamu N54. Pane zvakawanda zvakafanana pakati pemamodheru, seakambotaurwa, kunze kweiyo cast-iron crankshaft, iri 3 kg yakareruka pane yakashandiswa paN54.

Mukuwedzera, iyo N55 injini inoshandisa chete turbocharger, pane maviri semuN54B30. Mukuwedzera, muN54, imwe neimwe yemasilinda matatu yaitarisira imwe turbocharger. Zvakare, muN3, masilinda ane mutoro kune imwe yemakonye maviri anotyaira chinhu ichi. Nekuda kweizvi, dhizaini yeturbocharger yakareruka nekusvika 55 kg kana ichienzaniswa neyekare vhezheni yeyuniti.

BMW injini kushanda. Ndezvipi zvinetso zvinomuka pakushandisa?

Kushandisa injini itsva yeBMW N55 kunogona kukonzera mamwe matambudziko. Imwe yeakajairika ndeyekuwedzera kushandiswa kwemafuta. Izvi zvinonyanya kukonzerwa neiyo crankcase ventilation valve. Naizvozvo, zvakakosha kugara uchiongorora mamiriro ehunyanzvi echikamu ichi.

Dzimwe nguva kunewo matambudziko nekutanga mota. Chikonzero chinonyanya kupiswa hydraulic lifting mechanisms. Mushure mekutarisa mamiriro ehunyanzvi echikamu, shandisa emhando yepamusoro injini mafuta.

Chii chaunoda kuziva nezvekushanda kweyuniti?

Iwe unofanirwawo kuyeuka kuchinja majekiseni ako emafuta nguva dzose. Vanofanira kushanda makiromita 80 000 pasina dambudziko. Kana iyo yekutsiva nguva ichicherechedzwa, kushanda kwavo hakuzokonzerese matambudziko ane chekuita neakawandisa injini vibrations.

Nehurombo, iyo N55 ichine dambudziko rinoshungurudza neiyo yakanyanya kudzvanywa mafuta pombi.

Iwe unotoziva zvirevo zveiyo yega BMW unit shanduro. Iyo N55 injini, kunyangwe zvimwe zvikanganiso, inogona kurondedzerwa seyakavimbika uye yakasimba. Kugara uchigadzirisa uye kutarisisa kune meseji kunokubvumira kuti uishandise kwenguva yakareba.
