Ukuthetha ngeepiston zemoto, ngoko kufuneka sithethe malunga nesiganeko sokunkqonkqoza kwepiston. Le yenye yeentsilelo eziqhelekileyo zemoto. Ngaba uyayazi indlela yokucombulula ezo ntsilelo?
Ngaphambi kokusombulula ingxaki yokunkqonkqoza kwepiston, kufuneka siqale siqonde ukuba yintoni ebangela le nto.

◆Umsantsa phakathi kwepiston kunye nodonga lwesilinda mkhulu kakhulu.

Emva kokubaleka ixesha elithile, i-piston skirt kunye ne-cylinder iya kugutywa kakhulu, ibangele u-out-of-round kwaye ubethe isilinda.

◆Iintonga zokudibanisa zomntu ngamnye zikhubazekile ngenxa yezizathu ezahlukeneyo, ezibangela ukuba ipiston iguge, isithuba siba sikhulu kwaye isilinda siyankqonkqozwa. Ukunkqonkqoza kwePiston kuya kubangela ukusetyenziswa kwe-injini ngokugqithisileyo, ukuvuza kweoyile ye-injini, ukusetyenziswa kwe-oyile ephezulu, kunye noqoqosho olubi. Xa ipiston ibetha isilinda kakhulu, ipiston iya kwaphulwa kwaye isilinda sonakaliswe. Ngenxa yoko, intonga yokudibanisa iya kuphuka kwaye ibhloko ye-cylinder iya konakala.

Emva kokuba injini isebenze ixesha elide, i-cylinder piston igugile. Ukongeza kwi-lubrication engalunganga, i-gap ehambelanayo phakathi kwepiston kunye ne-cylinder iyanda ngenxa yokuguga, kwaye inyathelo elinzima livela kancinane ngaphantsi kweringi yokuqala yegesi, ebangela ukuba ipiston ibethe isilinda. Yenza ingxolo engaqhelekanga.

Kukulungele ukusombulula ingxaki ukuba uyasiqonda isizathu:

◆Ukuba kukho isandi esicacileyo sokunkqonkqoza xa ubushushu be-injini buqhelekile, zama ukunqanda ukusebenza ngesantya esiphezulu kwaye uqhaqhe kwaye uyilungise ngokukhawuleza.

Emva kokususa intloko ye-cylinder kunye nokukhupha i-piston, kufunyenwe ukuba i-cylinder ikhutshwe kakhulu, igxininiswe, okanye i-gap phakathi kwepiston kunye ne-cylinder inkulu kakhulu. Buyisela i-cylinder liner, ipiston kunye neringi yepiston.

◆Ukuba intonga yokudibanisa ifunyenwe ikhubazekile, kufuneka itshintshwe kangangoko kunokwenzeka.

Emva kokuba injini iqalisiwe, kukho isandi esinkqonkqozayo ngexesha lokusebenza lobushushu obuphantsi. Xa iqondo lokushisa liqhelekileyo, isandi siyanyamalala, ngoko unokusishiya.
