Ziyini Izindandatho Ze-Piston?
Incazelo kanye Nomklamo
Amasongo e-piston ayizindilinga zensimbi ezifakwe ema-piston ezinjinini zokushisa zangaphakathi. Ahlukaniswa ukuze avumele ukwanda nokufinyela ngesikhathi sokusebenza. Ngokuvamile enziwe ngensimbi ecijile, insimbi, noma ama-alloy athuthukile, amasongo e-piston anamuhla aklanywe ukuze amelane nokushisa okukhulu, ingcindezi, kanye nokungqubuzana.
Imisebenzi Eyinhloko
Izindandatho zepiston zenza imisebenzi emithathu ebalulekile:
1. Ukuvala igumbi lokushisa:Vimbela ukuvuza kwegesi ngesikhathi sokusha, ukuqinisekisa ukuthi amandla aphuma kahle kakhulu.
2. Ukudluliselwa kokushisa:Qhuba ukushisa kusuka episton kuya odongeni lwesilinda, uvimbele ukushisa ngokweqile.
3. Ukulawula uwoyela:Lawula ukusatshalaliswa kwamafutha odongeni lwesilinda ukuze unciphise ukungqubuzana ngenkathi uvimbela uwoyela owengeziwe ukuthi ungangeni ekamelweni lokushisa.
Kungani Ama-Piston Enezindandatho Ezintathu?
Indima Yendandatho Ngayinye
