Ibisabwa bya tekinike kuri piston

1. Bizaba bifite imbaraga zihagije, gukomera, misa ntoya, nuburemere bworoshye kugirango imbaraga zidafite imbaraga.
2. Umuyoboro mwiza wubushyuhe, kurwanya ubushyuhe bwinshi, umuvuduko mwinshi, kurwanya ruswa, ubushobozi buhagije bwo gukwirakwiza ubushyuhe, hamwe nubushuhe buto.
3. Hagomba kubaho coefficient ntoya yo guterana hagati ya piston nurukuta rwa piston.
4. Iyo ubushyuhe buhindutse, ingano nuburyo byahindutse bigomba kuba bito, kandi hagomba gukomeza kugaragara neza hagati yurukuta rwa silinderi na silinderi.
5. Coefficient nkeya yo kwagura ubushyuhe, uburemere bwihariye bwihariye, kugabanya kwambara neza nimbaraga zumuriro.

Uruhare rwa piston
Hamwe nibisabwa bikenerwa cyane kububasha, ubukungu, kurengera ibidukikije, no kwizerwa bya moteri mumodoka yose, piston yateye imbere mubicuruzwa byikoranabuhanga bihuza tekinolojiya mishya myinshi nkibikoresho byoroheje nimbaraga zikomeye, bidasanzwe -uburinganire bwa silindrike igizwe nubuso, hamwe nuburyo bwihariye bwa pin umwobo, kugirango hirindwe ubushyuhe, kwambara nabi, kuyobora neza, hamwe nimikorere myiza ya piston, kugabanya igihombo cyakazi cya moteri, no kugabanya gukoresha lisansi Urusaku nibisohoka.
Kugirango wuzuze ibisabwa byavuzwe haruguru, uruziga rwo hanze rwa piston rusanzwe rwashizweho nkuruziga rwihariye rudasanzwe (convex to elliptical), ni ukuvuga igice cyambukiranya perpendicular kuri piston axis ni ellipse cyangwa ellipse yahinduwe, na ovality ihinduka yerekeza kumurongo ukurikije itegeko runaka (nkuko bigaragara ku gishushanyo 1), hamwe na ovality ya 0.005mm;Igice cyo hanze cyigice cya piston ndende ni umurongo ukwiranye numurimo wo murwego rwohejuru, hamwe na kontour ya 0.005 kugeza 0.01 mm;Kugirango tunonosore ubushobozi bwo gutwara piston no kongera ingufu za moteri, umwobo wa pin ya piston iremereye mubisanzwe washyizweho nkubwoko bwa cone imbere imbere cyangwa ubwoko busanzwe bwo guhangayika bugoramye (umwobo udasanzwe ufite pin), hamwe na ubunini bwa pin umwobo wa IT4 hamwe na kontour ya 0.003mm.
Piston, nkibisanzwe byingenzi byimodoka, ifite tekinoroji ikomeye mubikorwa.Mu nganda zikora piston zo murugo, imirongo yumusaruro ikora igizwe nibikoresho rusange bigamije ibikoresho rusange nibikoresho byihariye bihuza ibiranga tekinoroji ya piston.
Kubwibyo, ibikoresho bidasanzwe byahindutse ibikoresho byingenzi byo gutunganya piston, kandi imikorere yayo nukuri bizagira ingaruka ku bipimo byerekana ubuziranenge bwibintu byingenzi biranga ibicuruzwa byanyuma.
