N57 injini - zvese zvaunoda kuziva

Iyo N57 injini ndeyemhuri yeinjini yedhiziri ine turbocharger uye yakajairika njanji system. Kugadzirwa kwakatanga muna 2008 uye kwakapera muna 2015. Tinopa ruzivo rwakakosha pamusoro pake.

N57 injini - data data

Injini yedhiziri inoshandisa DOHC valve control system. Iyo matanhatu-cylinder simba unit ine 6 masilinda ane 4 pistons mune imwe neimwe. Silinda yeinjini yakabereka 90 mm, piston sitiroko 84 mm pa16.5 compression. Iyo chaiyo injini yekusimuka ndeye 2993 cc. 

Injini yakashandisa 6,4 malita emafuta pamakiromita zana muguta, marita 100 pa5,4 km mumakwikwi akabatanidzwa uye 100 malita pa4,9 km mumugwagwa mukuru. Iyo unit yaida 100W-5 kana 30W-5 oiri kuti ishande nemazvo. 

Mota shanduro kubva BMW

Kubva pakutanga kwekugadzirwa kweBMW injini, marudzi matanhatu emagetsi emagetsi akagadzirwa. Vese vaive nebobo uye sitiroko ye84 x 90 mm, kutamiswa kwe2993 cc uye kumanikidza reshiyo ye3:16,5. Mhando dzinotevera dzaive dzemhuri yeN1:

• N57D30UL ine 150 kW (204 hp) pa3750 rpm. uye 430 Nm pa1750-2500 rpm. Yechipiri shanduro ine kubuda kwe155 kW (211 hp) pa4000 rpm. uye 450 Nm pa 1750-2500 rpm;
• N57D30OL 180 kW (245 hp) pa4000 rpm. uye 520 Nm pa1750-3000 rpm. kana 540 Nm pa 1750-3000 rpm;
• N57D30OL 190 kW (258 hp) pa4000 rpm. uye 560 Nm pa 2000-2750 rpm;
• N57D30TOP220 kW (299 hp) pa4400 rpm. kana 225 kW (306 hp) pa4400 rpm. uye 600 Nm pa1500-2500 rpm;
• N57D30TOP(TÜ) 230 kW (313 hp) pa4400 rpm. uye 630 Nm pa1500-2500 rpm;
• N57D30S1 280 kW (381 hp) pa4400 rpm. 740 Nm pa2000-3000 rpm.

Shanduro yemitambo N57D30S1

Paive zvakare nemutambo wechitatu-supercharger musiyano, apo yekutanga yaive neinoshanduka turbine geometry uye yaishanda zvakanaka kwazvo nekudzika kweinjini kumhanya, yechipiri nekumhanya kwepakati, kuwedzera torque, uye yechitatu yakagadzira mapfupi epamusoro esimba uye torque kumusoro. mutoro - pamwero we 740 Nm uye 280 kW (381 hp).

Dhiraivha dhizaini

Iyo N57 iine 30 ° supercharged, mvura-yakatonhorera inline injini. Inoshandisa camshafts maviri pamusoro - injini yedhiziri. Iyo injini block inogadzirwa neakareruka uye inogara yakasimba aluminium. Iyo crankshaft main bearing shells anogadzirwa necermet alloy.

Izvo zvakakoshawo kutsanangura magadzirirwo einjini silinda musoro. Iyo yakakamurwa kuita zvikamu zviviri, uko kuburitsa uye kupinza nzira, pamwe nemavharuvhu, ari pasi. Iyo yepamusoro ine base plate iyo camshafts inomhanya pairi. Musoro wacho wakashongedzerwawo ne exhaust gas recirculation channel. Chimiro cheN57 ndechekuti macylinders ane mitsara yakaoma yakasungirirwa kune cylinder block.

Camshafts, mafuta uye turbocharger

Chinhu chakakosha chekushanda kweinjini ndeye exhaust camshaft, iyo inotungamirirwa nechinhu chimwe chete chemagetsi ekutora. Izvo zvikamu zvakanyorwa zvine basa rekudzora mavharuvhu ekutora uye ekupera emasilinda. Nekuzodaro, kune iyo chaiyo mashandiro ekutora camshaft, cheni yekutyaira padivi reflywheel, yakamanikidzwa nehydraulic chain pullers, ine basa.

Muinjini yeN57, mafuta anobaiwa pakumanikidzwa kwe1800 kusvika 2000 bar yakananga mumasilinda kuburikidza neBosch Common Rail system. Yakasiyana misiyano yemagetsi unit inogona kunge iine akasiyana exhaust gasi turbocharger - inoshanduka geometry kana yakasanganiswa neintercooler, imwe kana maviri.

Kushanda kwedhiraivha unit - matambudziko akasangana

Panguva yekushanda kwemudhudhudhu, kukanganisa kunobatanidza nevortex shock absorbers kunogona kuitika. Somugumisiro wekushaya simba, injini inotanga kushanda zvisina kufanana, pamwe chete nezvikanganiso zvechiratidzo chechiratidzo. 

Rimwe dambudziko nderechizvarwa cheruzha rwakawanda. Manzwi asingadiwe ndiwo mhedzisiro yekutyoka crankshaft silencer. Dambudziko rinoonekwa pakumhanya kwe100 XNUMX. km uye ketani yenguva inoda kutsiviwa.

Iwe unofanirwawo kutarisisa kushandisa iyo chaiyo mhando yemafuta. Nekuda kweizvi, iyo yese system, senge turbine, inofanirwa kumhanya kweinenge 200 maawa pasina matambudziko. makiromita.

N57 injini yakakodzera tuning

Imwe yedzakajairika nzira dzekuwedzera injini simba ndeyekusimudzira iyo turbocharger. Nekuwedzera hombe vhezheni kana hybrid vhezheni kune injini, iyo yekutora mhepo yekuendesa paramita inogona kuvandudzwa zvakanyanya. Nekudaro, izvi zvichange zvichibatanidzwa nemazinga epamusoro ekupisa kwemafuta. 

Vashandisi veN57 vanosarudzawo kuridza ECU. Reassigning units inenge isingadhure uye inovandudza mashandiro. Imwe mhinduro kubva muchikamu ichi ndeyekutsiva kwete ECU chete, asiwo mabhokisi ekugadzirisa. Tuning inogonawo kushanda kune flywheel. Chinhu chine mashoma mashoma chinovandudza mashandiro eiyo simba unit nekuwedzera injini kumhanya.

Dzimwe nzira dzekuwedzera kugona kweinjini dzinosanganisira kukwidziridza pombi yemafuta, kushandisa majekiseni ekuyerera, kuisa silinda yakakwenenzverwa musoro, kit yekudyira kana sports catalytic converter, exhaust uye road cam.
