Ukumisela ezi fom zokukhuhlana zilandelayo kubaluleke kakhulu ekufundeni iimpawu zokukhuhlana kwamafutha aselwandle phantsi kwe-fuel-sulfur ephantsi kunye neemeko zomthwalo ophantsi, ukufuna izisombululo zokunciphisa ukuguga kunye nokwandisa ubomi benkonzo yamacandelo e-injini. Ezi ndlela zilandelayo zokunxiba ziyenzeka ikakhulu kwiindawo zokuthambisa ezixutyiweyo kunye nemida yokuthambisa, ngokuphucula umyinge wezongezo, ukunxitywa kwe-anti-mechanical kunye ne-anti-corrosive wear ye-lubricant inokuphuculwa, kwaye ubomi benkonzo yamacandelo omatshini bunokuphuculwa. yandisiwe kumsebenzi wokwenene.

Ukusuka kuhlalutyo lwezizathu ezisisiseko zokunxiba, "i-cylinder liner-piston ring" inxalenye yenjini yaselwandle ibandakanya ezi ndlela zine zilandelayo zokunxiba:

(1) Ukukhathala ukukhathala kuyinto eyenzeka apho i-friction surface ivelisa i-deformation enkulu kunye noxinzelelo kwindawo yokudibanisa, kwaye yenza iintanda kwaye ibhujiswe. Ukudinwa kubangelwa yilahleko yokukhuhlana kwamalungu omatshini phakathi koluhlu oluqhelekileyo;

(2) Ukunxitywa kwe-abrasive yinto eyenzeka ngayo apho amasuntswana aqinileyo abangela i-abrasions kunye nokuchithwa kwezinto ezingaphezulu kumphezulu we-friction pair kwi-motion ehambelanayo. Ukuguga okugqithisileyo kuya kugudisa udonga lwesilinda se-injini kwaye ngokuthe ngqo kubangele ukuba i-lubricant ibenzima ukwenza izinzile kumphezulu wodonga lwesilinda. Ifilimu ye-oyile, ebangela ukunyuka kokugqoka, i-aluminium kunye ne-silicon kwi-fuel yizona zizathu eziphambili zokugqoka i-abrasive;

(3) I-Adhesive wear ibangelwa ukunyuka koxinzelelo lwangaphandle okanye ukungaphumeleli kwe-lubricating medium, i-friction pair's surface "adhesive". I-Adhesive wear luhlobo olubi kakhulu lokunxiba oluya kubangela ukuba i-coating yempahla ekhethekileyo ebusweni be-cylinder liner ikhuphe, Ibangele ingozi enkulu ekusebenzeni okuqhelekileyo kwe-injini;

(4) Ukonakala kokuthotywa yinto eyenzeka kwilahleko yemathiriyeli ebangelwa yikhemikhali okanye i-electrochemical reaction phakathi kwezinto ezingaphezulu kunye nendawo ejikelezileyo ngexesha lentshukumo ehambelanayo yomphezulu weperi friction, kunye nokulahleka kwempahla okubangelwa sisenzo soomatshini. Kwimeko ye-corrosion enzima kunye nokugqoka, izinto ezingaphezulu kwindonga ye-cylinder ziya kuhlanjululwa, kwaye nangona xa umphezulu we-friction pair's ushukunyiswa ngokulinganayo, ukugquma komhlaba kuya kulahlekelwa iimpawu zokuqala eziphathekayo kwaye zonakaliswe kakhulu.
