1. Chikonzero chemhete yepiston
(1) Chimiro chepiston ring material hachizadzise zvinodiwa nehunyanzvi, uye sangano rakasununguka.
(2) Kuoma kwepiston mhete yakaderera uye haina kuzadzisa zvinodiwa.
(3) Kugadzikana kwekupisa kwemhete yepiston kwakashata, uye chimiro chemetallographic chinoshanduka zvakanyanya.

2. Zvikonzero zve cylinder liner
(1) Iyo dhayamita yemukati ye cylinder liner haina kusangana nezvinodiwa uye yakakura kwazvo kana idiki.
(2) Kuomarara kwegomba remukati re cylinder liner harina kusangana nezvinodiwa, uye firimu yemafuta haisi nyore kuumba.
(3) The verticality uye kutenderera kwecylinder liner hazvienderane nezvinodiwa.

3. Zvimwe zvinhu
(1) Hunhu hwefirita yemhepo uye sefa yemafuta haina kunaka, huwandu hukuru hweguruva kana kusvibiswa kwakanyanya mumafuta kunopinda mucylinder.
(2) Kusarudzwa kusina kunaka kwefriction pair.

4. Mafuta emhando
(1) Oiri yakashata.
(2) Hunhu hwemafuta hwakaderera, iyo inotungamira inokwirisa, uye zvigadzirwa zvinopisa zvinogadzira abrasive, izvo zvinokonzeresa kupfeka.

5. Kugadzirisa
(1) Panguva yekugadzirisa, kuchena hakuna kukwana, uye kune tsvina yakaita sejecha kana simbi muhumburumbira.
(2) Kusarudzwa kwakashata kwepiston mhete kana saizi yepiston.
(3) Pakuunganidza zvikamu zvinofamba, iyo yakakodzera clearance uye bhoti torque haizadzise zvinodiwa.

6. Shandisa
(1) Tembiricha yeinjini haina kujairika, yakakwira zvakanyanya kana yakaderera zvakanyanya kunowedzera kupera kwezvikamu zvemuchina.
