(1) Litšobotsi tsa phoso tsa piston le piston ring leakage

Ho lekana pakeng tsa piston le tumello ea lebota la silinda ho amana ka kotloloho le boleng ba tlhokomelo ea enjene le bophelo ba ts'ebeletso. Nakong ea tlhokomelo ea enjene le ho e hlahloba, beha piston e shebile fatše ka har'a cylinder bore, 'me u kenye gauge ea botenya le bolelele bo loketseng ka har'a silindara ka nako e le 'ngoe. Ha khatello e lehlakoreng e sebelisoa, lerako la silinda le piston li tsamaisana le bokaholimo ba piston. Sebelisa tekanyo ea selemo ho hatella matla a ho hula a boletsoeng ho Ho loketse ho ntša tekanyo ea botenya ka bonolo, kapa pele u lekanya bophara ba moleka oa piston ka micrometer e ka ntle, ebe u lekanya bophara ba cylinder ka cylinder bore gauge. Silinda e bore ho tlosa bophara bo ka ntle ba moleka oa piston ke sebaka se loketseng.
