Izidingo zobuchwepheshe zepiston

1. Izoba namandla anele, ukuqina, isisindo esincane, kanye nesisindo esincane ukuze kuqinisekiswe amandla angenawo amandla.
2. I-conductivity enhle yokushisa, ukumelana nokushisa okuphezulu, ukucindezela okuphezulu, ukumelana nokugqwala, ikhono elanele lokukhipha ukushisa, nendawo encane yokushisa.
3. Kufanele kube ne-coefficient encane yokungqubuzana phakathi kwepiston nodonga lwepiston.
4. Uma izinga lokushisa lishintsha, ubukhulu kanye noshintsho lomumo kufanele lube luncane, futhi imvume encane phakathi kodonga lwesilinda kanye ne-cylinder kufanele igcinwe.
5. I-coefficient ephansi yokwandisa okushisayo, amandla adonsela phansi amancane, ukunciphisa ukugqoka okuhle namandla okushisa.

Indima yepiston
Ngokukhula kwezidingo eziqinile zamandla, umnotho, ukuvikelwa kwemvelo, nokuthembeka kwenjini kuyo yonke imoto, i-piston isithuthuke yaba umkhiqizo wobuchwepheshe obuphezulu ohlanganisa ubuchwepheshe obusha obuningi njengezinto ezintsha ezingasindi nezinamandla aphezulu, okukhethekile. -indawo eyinhlanganisela eyisilinda emise okwesilinda, kanye nezimbobo zamaphini ezimise okukhethekile, ukuqinisekisa ukumelana nokushisa, ukumelana nokugqokwa, isiqondiso esizinzile, nomsebenzi omuhle wokuvala ipiston, ukunciphisa ukulahleka komsebenzi wokungqubuzana kwenjini, kanye nokunciphisa ukusetshenziswa kukaphethiloli Umsindo nokukhipha umoya.
Ukuze kuhlangatshezwane nalezi zidingo zokusebenza ezingenhla, indingilizi yangaphandle yepiston ivame ukuklanywa njengendilinga yangaphandle emise okukhethekile (i-convex kuya ku-elliptical), okungukuthi, ingxenye ephambanayo i-perpendicular to piston axis i-ellipse noma i-ellipse eguquliwe, futhi i-ovality ishintsha ngokuhambisana ne-eksisi ngokomthetho othile (njengoba kuboniswe kuMfanekiso 1), ngokunemba kwe-ovality engu-0.005mm;I-contour yangaphandle yesigaba se-piston longitudinal iyijika elifanele lomsebenzi wokuhleleka okuphezulu, ngokunemba kwe-contour ye-0.005 kuya ku-0.01 mm;Ukuze kuthuthukiswe amandla okuthwala i-piston futhi kwandiswe amandla enjini, imbobo yephini ye-piston elayisha kakhulu imvamisa iklanywa njengohlobo lwekhoni yangaphakathi encane noma uhlobo oluvamile lwe-stress curved surface (imbobo yephini elimise okukhethekile), ene- ukunemba kosayizi wembobo yephini ye-IT4 kanye nokunemba kwekhontayutha okungu-0.003mm.
I-Piston, njengengxenye evamile yezimoto eyinhloko, inezici eziqinile zobuchwepheshe ekwenzeni imishini.Embonini yokukhiqiza i-piston yasekhaya, imigqa yokukhiqiza imishini ivame ukwakhiwa ngamathuluzi omshini wenhloso ejwayelekile kanye nemishini ekhethekile ehlanganisa izici zobuchwepheshe be-piston.
Ngakho-ke, imishini ekhethekile isibe yimishini ebalulekile yomshini we-piston, futhi umsebenzi wayo nokunemba kuzothinta ngokuqondile izinkomba zekhwalithi zezici ezibalulekile zomkhiqizo wokugcina.
