1: kweimpahla ye-pistonkanye nobuchwepheshe babuncike ohlotsheni lwenjini oluhlukahlukene, izimo zokusetshenziswa, nokucatshangelwa kwezindleko.
Izinto ze-Piston zifaka: I-aluminium ye-Cast, i-aluminium Forged, insimbi ne-Ceramic.
I-aluminium ye-cast iyinto evame ukusetshenziswa kakhulu ku-piston. Ilula, ayibizi, futhi inikeza i-thermal conductivity enhle. Kodwa-ke, ayinamandla njengezinye izinto futhi ingakhubaza ngaphansi kwengcindezi ephezulu noma amazinga okushisa aphezulu.
Impahla ye-aluminium efojiwe inamandla kune-aluminium ephonsiwe futhi ingamelana nengcindezi ephakeme kanye nemithwalo yezinga lokushisa. Ivame ukusetshenziswa ezinjinini ezisebenza kahle kakhulu.
Ama-piston ensimbi anamandla kakhulu futhi aqinile, futhi angakwazi ukubhekana nengcindezi ephezulu kakhulu kanye nemithwalo yezinga lokushisa. Zivame ukusetshenziselwa izinjini ze-diesel nezinye izinhlelo zokusebenza ezisindayo ezifana namaloli anzima, amaloli asindayo aba yithuluzi lokuthutha elibaluleke kakhulu ekuphileni kwethu, bonke abasebenzisi baqaphela kakhulu ngakho.
Ama-piston e-Ceramic alula kakhulu futhi anikeza ukufakwa kwe-thermal okuhle kakhulu. Zivame ukusetshenziswa ezinjinini ezisebenza kahle nasezinhlelweni zomjaho, njengoba izindleko zibiza kakhulu kunezinye.
Ubuchwepheshe be-piston nabo buthuthukile eminyakeni yamuva nje, ngokuthuthukiswa kwezingubo zokugqoka nezinye izindlela zokwelapha ezingathuthukisa ukusebenza nokuqina. Ezinye izibonelo zihlanganisa:
1. I-anodizing eqinile: Le nqubo ihlanganisa ukumboza ipiston ngongqimba oluqinile, olungagugi lwe-aluminium oxide. Lokhu kungathuthukisa ukuqina futhi kunciphise ukungqubuzana.
2. Izembatho ezinciphisa i-friction: Lezi zingubo zenzelwe ukunciphisa ukungqubuzana phakathi kwezindonga zepiston ne-cylinder. Lokhu kungathuthukisa ukusebenza kahle futhi kunciphise ukuguga.
3. Izembatho zesithiyo ezishisayo: Lezi zembatho zisetshenziselwa umqhele we-piston ukuze kuthuthukiswe ukushisa kokushisa nokunciphisa ukucindezeleka okushisayo. Lokhu kungathuthukisa ukusebenza futhi kunciphise ingozi yokuhluleka kwepiston.
Ama-piston amaningi manje aklanywe ngokunciphisa isisindo engqondweni, esebenzisa izinto ezithuthukisiwe nezindlela zokukhiqiza ukuze kuncishiswe isisindo ngenkathi kugcinwa amandla nokuqina. Lokhu kungathuthukisa ukusebenza nokusebenza kahle kukaphethiloli.
