Ko firita yemhepo inofanira kutsiviwa here kana isina kusviba kwemakore matatu?
Kana firita remhepo rikasatsiviwa kwenguva yakareba, tarisa kuti harina kusviba here, zvinokurudzirwa kusarudza kana uchida kuritsiva zvichienderana nechiyero chekutsiva chiri mubhuku rekugadzirisa mota. Nekuti kuongorora mhando yechinhu chefirita remhepo hakusi chiratidzo chekuti pamusoro paro pakasviba here, saizi yekudzivirira mhepo uye kushanda zvakanaka kwekusefa zvinokanganisa simba reinjini.
Basa refirita remhepo yemotokari nderekusefa tsvina inokuvadza mumhepo inopinda mufirita kuderedza kupera kwefirita, piston, piston ring, vharuvhu nechigaro chevharuvhu nekukurumidza. Kana firita remhepo rikawanda kana kuti mhepo isina kuyerera zvakakwana, zvichaita kuti injini ipinde zvishoma, simba risakwane, uye mafuta emotokari awedzere zvakanyanya.
Mafirita emhepo emota anowanzo ongororwa makiromita zviuru gumi ega ega, uye anotsiviwa makiromita zviuru makumi maviri kusvika makumi matatu ega ega. Kana ikashandiswa munzvimbo dzine guruva guru uye mhepo isina kunaka, nguva yekugadzirisa inofanira kupfupikiswa zvinoenderana. Pamusoro pezvo, mhando dzakasiyana dzemhando, mhando dzakasiyana dzeinjini, kuongororwa uye kutenderera kwekutsiva mafirita emhepo kuchave kwakasiyana zvishoma, zvinokurudzirwa kutarisa zvinodiwa mubhuku rekugadzirisa usati wagadzirisa.
