1. Isizathu seringi yepiston

(1) Isixhobo seringi yepiston ayihlangabezani neemfuno kwaye amandla okugoba abi;

(2) Umaleko wonyango womphezulu weringi ungqingqwa kakhulu, kwaye ukumelana nokudinwa kubi.

2. Izizathu zepiston

(1) Emva kokuba i-groove ye-ring igugile, inesimo sexilongo, esenza i-piston ring ijike kwaye iphuke xa isebenza;

(2) Ipiston ikhubazekile okanye iqhekezwe bubushushu, kwaye iringi ikhubazekile kwaye yaphulwe ngokucinezelwa;

(3) I-groove ye-piston ring ayilingani, i-ring inamathele kwaye ilahlekelwa u-elasticity yayo, kwaye iphulwe yimpembelelo.

3. Izizathu ze-cylinder liner

(1) I-diameter yangaphakathi ye-cylinder liner incinci, kwaye ukuvulwa kweringi yepiston kunamathele kwaye kwaphukile;

(2) I-diameter yangaphakathi ye-cylinder liner inkulu, i-gap ekupheleni kwendandatho inkulu, kwaye i-flutter iqiniswe xa i-ring isebenza;

(3) I-cylinder liner i-wavy, kwaye i-ring yaphulwa ngamandla angaqhelekanga ngexesha lokusebenza.

4. Ezinye izizathu

(1) Ukuthanjiswa kakubi;

(2) Ukunxitywa kweringi kudlule kumda wenkonzo, kwaye iya kuphuka emva kokusetyenziswa okuqhubekayo;

(3) Yaphukile ngenxa yofakelo olungafanelekanga kunye nokuchithwa;

(4) Isinyathelo seziko eliphezulu elifileyo le-cylinder liner endala ayipheli.
