Matambudziko uye kuipa kweiyo ICE modhi anowanzo kufanana neM52B25. Pamusoro pechinyorwa, ane overheating, izvo zvinowanzokonzera kukanganisa kwegasi rekugovera michina. Mhinduro yekupisa kupisa inowanzo kuchenesa radiator, kutarisa pombi, thermostat, radiator cap. Dambudziko rechipiri nderekushandiswa kwemafuta zvakadarika zvakajairwa. MuBMW, iyi, in musimboti, idambudziko rakajairika, iro rinosanganiswa neasina-kupfeka-resistant piston mhete. Mukusavapo kwekuvandudzwa pamadziro emasilinda, zvindori zvinogona kungotsiviwa uye mafuta haazosiyi zvinopfuura zvakatemwa. Hydraulic lifters painjini idzi "se" kune coke, izvo zvinotungamira mukukanganisa.

Iyo VANOS system inonyatsonzwa nezvekushanda kwejini uye kana paine kusagadzikana kushanduka, kushanda kusina kuenzana kazhinji kana kudonha kwesimba, inopera zvakanyanya. Kuti uigadzirise, iwe unofanirwa kuve uine system yekugadzirisa kit.

Kusavimbika crankshaft uye camshaft chinzvimbo sensors zvinowanzoita kuti injini isatange, kunyangwe kunze zvese zvakanaka. Iyo thermostat inoda kudonha, uye kazhinji sosi yakadzikira pane iyo yeM50.

Pakati pezvakanakira, zvinogona kucherechedzwa kuti injini idzi nhatu hadzisi kunyanya kutarisisa kunaka kwepeturu. Kuzvigadzirisa kazhinji hazvikurudzirwe, pamwe nekutenga zvekuchinjisa, sezvo vatove vasakara. Zvisinei, kune avo vanoomerera muchishuvo chavo, pane nzira yakaratidza - yekuisa iyo yakawanda M50B25, camshafts kubva kuS52B32 uye chip tuning. Tuning yakadaro ichasimudza simba kusvika ku250 hp. Imwe nzira iri pachena inofinha kusvika kumarita matatu, inoperekedzwa nekutenga kweM3B54 crankshaft uye kucheka piston ne 30 mm.

Kuisa turbine pane chero yakatsanangurwa injini inzira yakakwana yekuwedzera simba. Semuenzaniso, M52B28 ine Garrett turbine uye yakanaka processor setup inoburitsa ingangoita 400 hp. neboka restock piston.

Nzira dzekugadzirisa dzeM52V25 dzakati siyana. Pano zvakakosha kutenga, kuwedzera kune yakawanda yekutora kubva ku "hama" M50V25, zvakare crankshaft ine M52V28 yekubatanidza tsvimbo, pamwe ne firmware. Camshafts uye exhaust system zviri nani kuisa ipapo S62 - pasina ivo, haizozununguke kana uchigadzira. Saka, nehuwandu hwemarita maviri, iwe uchawana zvinopfuura 2 hp.

Kuti usimudze simba pane diki 2-litre injini, iwe uchada kana bore kusvika pakakwirira 2.6 malita kana turbine. Akafinhwa uye akarongeka, achakwanisa kupa 200 hp. Turbocharged nerubatsiro rweyakakosha turbo kit inozopedzisira yakwanisa kusvina kunze 250 hp. pa 2 malita ehuwandu hwekushanda. Iyo Garrett kit inogona kutsiviwa neLysholm, iyo ichapawo simba rekuwedzera mukati memiganho yakafanana.
