Ukusetshenziswa kwamaphistoni ahlukene ezinjinini kungathonywa yizici ezimbalwa, okuhlanganisa imigomo ethile yokuklama kanye nezidingo zenjini, ukusetshenziswa okuhlosiwe, ukuphuma kwamandla, ukusebenza kahle, nokucatshangelwa kwezindleko. Nazi izizathu ezimbalwa zokuthi kungani ama-piston ahlukene angasetshenziswa ezinjinini:
1. Usayizi Wenjini Nokucushwa: Osayizi benjini abahlukene kanye nokucushwa (okufana nomugqa, okumise okwe-V, noma okuphikiswa ngokuvundlile) kunezidingo ezihlukene zamaphistoni. Ubukhulu bepiston, okuhlanganisa nobubanzi bayo, ubude be-stroke, nobude bokuminyanisa, kwenzelwa ukuthuthukisa ukusebenza kahle nokungena ngaphakathi kwezingqinamba zedizayini yenjini.
2. Okukhipha Amandla Nokusebenza:Idizayini ye-pistoningalungiswa ukuze kuzuzwe ukuphuma kwamandla athile kanye nezici zokusebenza. Izinjini ezisebenza kahle kakhulu zivame ukudinga ama-piston angakwazi ukumelana namazinga okushisa aphezulu nezingcindezi, abe nezici zokupholisa ezithuthukisiwe, futhi anikeze ukuvala okuthuthukisiwe ukuze kwandiswe amandla nokusebenza kahle.
3. Ukukhethwa Kwezinto Ezibalulekile: Izinto ze-piston zingahluka kuye ngezici ezifana nohlobo lwenjini, amandla afiswayo, isisindo, kanye nezindleko. Izinto ezivamile ze-piston zifaka ama-alloys e-aluminium ekhonjiwe, ama-alloys e-aluminium akhiwe, nensimbi. Izinto ezisetshenziswayo ezahlukahlukene zinikeza izinzuzo ezahlukahlukene kanye nokuhwebelana ngokuya ngokuqina, ukunwetshwa okushisayo, ukunciphisa isisindo, kanye nezindleko.
4. Uhlobo Lwamafutha: Uhlobo lukaphethiloli olusetshenziswa enjinini lungaphinde lube nomthelela ekwakhiweni kwepiston. Izinjini ezidizayinelwe izinto zokubasa ezihlukene, ezifana nophethiloli, udizili, noma ezinye izibaseli ezifana ne-ethanol noma igesi yemvelo, zingase zidinge amadizayini amaphistoni ahlukene ukuze afakele ukuhlukahluka kwezici zokuvutha, izilinganiso zokuminyanisa, namazinga okushisa okusebenza.
5. Ukungeniswa Okuphoqiwe: Izinjini ezifakwe ukungeniswa ngempoqo, njengamashaja amakhulu noma ama-turbocharger, ngokuvamile zidinga amaphistoni aqinile ukuze zimelane nokucindezela okukhulayo namazinga okushisa akhiqizwa ukungeniswa ngenkani. Lawa ma-piston angase abe nezakhiwo eziqinisiwe nezici zokupholisa ezithuthukisiwe ukuze asingathe ingcindezi eyengeziwe.
6. Ukucatshangelwa Kwezindleko: Idizayini ye-piston nayo ingathonywa ukucatshangelwa kwezindleko. Izinjini ezikhiqizwe ngobuningi ezisetshenziswa ezimotweni ezijwayelekile zingase zibeke phambili ukusebenza kahle kwezindleko, okuholela ekwakhekeni kwemiklamo elula yepiston ehlangabezana nemigomo yokusebenza oyifunayo kuyilapho kugcina izindleko zokukhiqiza ziphansi. Ngakolunye uhlangothi, izinjini ezisebenza kahle kakhulu noma izinhlelo zokusebenza eziyisipesheli zingase zibeke phambili ukusebenza kunezindleko, kubangele imiklamo ethuthuke kakhulu futhi ebizayo yepiston.
Kubalulekile ukuqaphela ukuthi ukwakheka kwenjini kuyinqubo eyinkimbinkimbi, futhi kucatshangelwa izici eziningi lapho kukhethwa ukucushwa kwepiston. Onjiniyela balungiselela izingxenye ezahlukahlukene, okubandakanya ama-piston, ukuze bathole ibhalansi efiselekayo yokusebenza, ukuqina, ukusebenza kahle, kanye nezindleko zomklamo othile wenjini kanye nokusebenza okuhlosiwe.
