(1) Ipiston kunye neringi yepiston ukuvuza iimpawu zempazamo

Ukulingana phakathi kwepiston kunye nokukhutshwa kodonga lwe-cylinder kuhambelana ngokuthe ngqo nomgangatho wokugcinwa kwe-injini kunye nobomi benkonzo. Ngexesha lokugcinwa kwe-injini kunye nokuhlolwa, beka ipiston phantsi kwi-cylinder bore, kwaye ufake igeyiji yobukhulu obufanelekileyo kunye nobude kwi-cylinder ngaxeshanye. Xa uxinzelelo lwecala lusetyenziswa, udonga lwesilinda kunye nepiston zihambelana ne-thrust surface yepiston. Sebenzisa ibhalansi yasentwasahlobo ukucinezela amandla okutsala achaziweyo kuya Kufanelekile ukukhupha i-gauge yobunzima ngobunono, okanye uqale ulinganise ububanzi be-piston skirt kunye ne-micrometer yangaphandle, kwaye emva koko ulinganise i-cylinder diameter nge-cylinder bore gauge. I-cylinder bore thabatha i-diameter yangaphandle ye-piston skirt yi-access clearance.

(2) Ukuxilongwa kunye nokusombulula ingxaki yokuvuza kwepiston kunye neringi yepiston

Beka iringi yepiston ibe mcaba kwicylinder, tyhala iringi caba ngepiston endala (xa utshintsha iringi ukwenzela ukulungiswa okuncinci, yityhale iye kwindawo apho umsesane olandelayo ushukuma uye kwindawo ephantsi), kwaye ulinganise isithuba sokuvula ngobungqimba. igeyiji. Ukuba i-gap yokuvula incinci kakhulu, sebenzisa ifayile ecocekileyo ukuze ufake ifayile encinci ekupheleni kokuvula. Ukuhlolwa rhoqo kufuneka kwenziwe ngexesha lokulungiswa kwefayile ukukhusela ukuvula ukuba kukhulu kakhulu, kwaye ukuvulwa kufuneka kube flat. Xa ukuvuleka kweringi kuvaliwe kuvavanyo, akufuneki kubekho ukuphambuka; isiphelo esifayiliweyo kufuneka singabina burrs. Jonga i-backlash, faka i-piston ring kwi-ring groove kwaye ujikeleze, kwaye ulinganise isithuba ngegeji yobukhulu ngaphandle kokukhupha ipini. Ukuba ucoceko luncinci kakhulu, beka intsimbi yepiston kwipleyiti eyisicaba egqunywe ngelaphu le-emery okanye ipleyiti yeglasi egqunywe ngevalve yesanti kwaye ucole. Khangela i-backlash kwaye ubeke i-piston ring kwi-groove ye-ring, i-ring iphantsi kune-groove bank, ngaphandle koko i-ring groove kufuneka iguqulwe kwindawo efanelekileyo.
