Zvindori zvepiston zvakakamurwa kuita zvindori zvegasi uye zvindori zvemafuta. Injini ye 195 dhiziri inoshandisa inkstone gasi mhete nemhete imwe yemafuta, nepo Z1100 injini yedhiziri inoshandisa mhete mbiri dzegasi uye mhete yemafuta imwe. Iwo akaiswa mupiston ring groove, anotsamira pane elastic simba kunamatira kumadziro ecylinder, uye kufamba kumusoro nekudzika nepiston. Pane mabasa maviri emhete yemhepo, imwe ndeyekusimbisa humburumbira, kuitira kuti gasi riri muhumburumbira rirege kupinda mukati me crankcase zvakanyanya sezvinobvira; imwe yacho kuendesa kupisa kwemusoro wepiston kumadziro ecylinder.

Kamwe mhete yepiston yadonha, huwandu hukuru hwehutembiricha hwegasi hunobuda kubva pakakorokoza pakati pepiston necylinder. Kwete chete kupisa kunogamuchirwa nepistoni kubva kumusoro hakugoni kuendeswa kumadziro evhavha kuburikidza nemhete yepistoni, asiwo kunze kwepistoni uye mhete yepiston ichapiswa zvakasimba negesi. , zvakazoita kuti piston nepiston ringi ripere. Iyo mhete yemafuta inonyanya kuita semafuta ekutsvaira kudzivirira mafuta kuti asapinda mukamuri rinopisa. Nzvimbo yekushanda yemhete yepiston ine hutsinye, uye zvakare iri panjodzi chikamu cheinjini yedhiziri.

Teerera kune anotevera mapoinzi paunenge uchitsiva piston mhete:

(1) Sarudza rin'i yepiston inokwanisa, uye shandisa piston mhete yepiston kuvhura zvakanaka mhete yepiston paunenge uchiiisa papiston, uye dzivirira simba rakawandisa.

(2) Pakuunganidza mhete yepiston, teerera kune kwainotungamira. Iyo chrome-yakapfatwa mhete inofanirwa kuiswa mumhete yekutanga, uye yemukati cutout inofanira kunge iri kumusoro; kana mhete yepiston ine yekunze cutout yakaiswa, yekunze cutout inofanira kunge yakadzika; Kazhinji, mupendero wekunze une machamfer, asi mupendero wekunze wepazasi pemuromo wezasi hauna chamfers. Teerera kune yekumisikidza kutungamira uye usaiise zvisizvo.

(3) Isati yaiswa piston-yekubatanidza tsvimbo muhumburumbira, nzvimbo dzekupedzisira kwemhete yerin'i yega yega dzinofanirwa kugovaniswa zvakaenzana munzira yepiston circumference, kuitira kudzivirira kubuda kwemhepo uye kubuda kwemafuta kunokonzerwa nekupfuura. .
