12. Supercharger kutonhora kuburikidza nekutakura imba.

Shanduko idzi dzese dzakavandudza kushanda kweinjini uye maitiro ayo.

kutadza

Maererano nekuongorora kwevaridzi pamaforamu akakodzera, hazvibviri kutsanangura chero matambudziko akakomba. Vazhinji vatyairi vanogutsikana neinjini idzi uye mota dzinobva pazviri zvakazara. Chinhu chimwe chete ndechokuti kushandiswa kwemafuta muguta hakuna kunyanya kusiyana ne4-cylinder units. Muguta, injini "inodya" 10-12 malita, mumugwagwa mukuru - 6.5-7 (izvi hazvishandi kune injini yakasanganiswa paI8). Hapana kushandiswa kwemafuta kwakaonekwa, pakanga pasina rpm dips kana mamwe matambudziko. Ichokwadi, injini idzi dziri vaduku uye mumakore 5-10, zvichida kukanganisa kwavo kuchava pachena nekuda kwekurasikirwa kwechigadzirwa.

Kondirakiti ICE

Injini dzeB38B15 itsva, uye dzakapihwa kuti dzekutanga dzakagadzirwa muna 2013, dzinoramba dziri nyowani sepakati pa2018. Zvinenge zvisingaite kuburitsa sosi yeiyi mota mumakore mashanu, saka B5B38 makondirakiti motors inokurudzirwa kutengwa.

Zvichienderana nemamiriro eyuniti, mileage uye zvakabatanidzwa, izvi zvinomera zvemagetsi zvinogona kutengwa neavhareji ye200 zviuru rubles.

Paunosarudza injini yekontrakiti, iwe unofanirwa kutanga wafunga nezvegore rekuburitswa kwayo uye edza kutora senge nyowani injini inopisa mukati sezvinobvira. Zvikasadaro, sosi yakakura haigone kuvimbiswa.

mhedziso

Mota dzemhuri yeB38 ndeyepamusoro-tekinoroji yemazuva ano zvidyarwa zvemagetsi umo zvichangobva kuitika tekinoroji zvekunetsekana kweGerman zvinoitwa. Nevhoriyamu diki, vanopa simba rakawanda rebhiza, vane torque yakakwirira.
