Mafuta mavara. Ndeupi ruzivo rwakanyanya kukosha?
Kunyangwe iwo mamaki pamafuta einjini angaite seakaoma, haana kunetsa kunzwisisa. Ungofanire kunge ukwanisa kuaverenga.
Iyo yekutanga parameter yekuteerera kune viscosity. Iyo idiki iyo, yakaderera mafuta uye kuramba kweinjini panguva yekutanga-up uye kushanda. Mafuta einjini ane yakaderera viscosity akasarudzwa: 0W-30, 5W-30, 0W-40 uye ane yakasarudzika ekudzivirira zvivakwa pakudziya kwakaderera. 5W-40 ndeyekubvumirana, i.e. pakati viscosity mafuta. 10W-40, 15W-40 inoreva yakakwirira viscosity uye kuwedzera kutenderera kuramba. 20W-50 ine yakakwira viscosity uye yakakwirira kumhanya kuramba, pamwe nekudzivirira kurinani kweinjini pakudziya kwepamusoro.
Chimwe chinhu kunaka kwemafuta. Makirasi emhando yepamusoro anogona kutsanangurwa zvinoenderana neACEA (European Vehicle Manufacturers Association) kana API (American Petroleum Institute) zviyero. Iwo aimbova akakamura oiri mune ayo akagadzirirwa injini dzepeturu (bhii A), injini dzedhiziri (bhii B) uye injini dzepeturu dzine catalytic masisitimu, pamwe nemainjini edhiziri ane DPF mafirita (bhii C). Tsamba yacho inoteverwa nenhamba muhuwandu hwe1-5 (yekirasi C kubva ku1 kusvika ku4), makirasi aya anopa ruzivo pamusoro pemhando dzakasiyana-siyana dzekudzivirira kupfeka, pamwe nekudzivirira kwemafuta mukati, izvo zvinokanganisa zvakananga kushandiswa kwemafuta.
Panyaya yemagiredhi emhando yeAPI, maoiri einjini dzepeturu anoratidzwa netsamba S inoteverwa nearufabheti tsamba, semuenzaniso, SJ (inowedzera iyo tsamba, inokwirisa mhando yemafuta). Zvakafanana nemafuta einjini yedhiziri, zita ravo rinotanga netsamba C uye rinopera neimwe tsamba, seCG. Parizvino, iwo epamusoro API makirasi SN uye CJ-4.
Onawo: Maitiro ekuchengetedza mafuta?
Vazhinji vagadziri vemotokari vanosuma yavo miyero yakavakirwa painjini dyno bvunzo uye yemugwagwa. Aya marudzi emayero ari Volkswagen, MAN, Renault kana Scania. Kana zvibvumirano zvemugadziri zviri pakurongedzerwa, ipapo oiri yakapfuura miyedzo yakaoma kuona zvimiro zvayo.
Iyo yekurongedza inogona zvakare kuve neruzivo nezve kurudziro yemugadziri. Castrol yave ichishanda nevagadziri vemotokari kwemakore uye iwo mafuta emhando iyi anokurudzirwa injini dzemotokari dzakadai seBMW, Ford, Seat, Volvo, Volkswagen, Audi, Honda kana Jaguar, iyo inogona kuwanikwa kwete pamafuta chete. kurongedza, asiwo pane iyo mafuta filler cap mumotokari idzi.
Onawo: Iyi iRolls-Royce Cullinan.
