Transmission oiri inotonhorera basa
Nekuda kwekuti oiri ine thermal conductivity uye inogara ichiyerera muinjini, iyo inotonhorera yemafuta inoita basa rekutonhora muinjini crankcase, clutch, vharafu musangano, etc. Kunyangwe kune enjini-yakatonhorera injini, chikamu chega chinogona kutonhodzwa nemvura ndicho silinda musoro uye cylinder madziro, uye zvimwe zvikamu zvichiri kutonhodzwa nemafuta anotonhorera.
