Mphete za pistoni zimagwiritsidwa ntchito kwambiri pamakina osiyanasiyana amagetsi, monga injini za nthunzi, injini za dizilo, injini zamafuta, compressor, makina osindikizira a hydraulic, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kwambiri pamagalimoto, masitima apamadzi, zombo, ma yacht ndi zina zotero. Nthawi zambiri, mphete ya pisitoni imayikidwa mumphepete mwa pisitoni, ndipo pisitoni, silinda liner, mutu wa silinda ndi zigawo zina za chipindacho kuti zigwire ntchito.

Ntchito ya mphete ya pisitoni imaphatikizapo kusindikiza, kuwongolera mafuta (kuwongolera mafuta), kuwongolera kutentha (kutengera kutentha), kuwongolera (thandizo) magawo anayi. Kusindikiza: Kumatanthawuza kusindikiza gasi, musalole kuti mpweya woyaka m'chipindacho utsike ku crankcase, kutayikira kwa mpweya kumayendetsedwa pang'onopang'ono, kuwongolera kutentha. Kutuluka kwa mpweya sikungochepetsa mphamvu ya injini, komanso kumapangitsa kuti mafuta awonongeke, omwe ndi ntchito yaikulu ya mphete ya gasi; Sinthani mafuta (kuwongolera mafuta): mafuta owonjezera opaka pakhoma la silinda amachotsedwa, ndipo khoma la silinda limakutidwa ndi filimu yopyapyala yamafuta kuti zitsimikizire kuti silinda ndi pisitoni ndi mphete, yomwe ndi ntchito yayikulu. mphete ya mafuta. M'mainjini amakono othamanga kwambiri, chidwi chapadera chimaperekedwa ku gawo la filimu yamafuta a piston; Kutentha kwamoto: kutentha kwa pisitoni kumaperekedwa ku liner ya silinda kudzera mu mphete ya pisitoni, ndiko kuti, kuzizira. Malinga ndi deta yodalirika, 70 ~ 80% ya kutentha komwe kumalandiridwa ndi pisitoni pamwamba pa pisitoni yosakhazikika kumamwazikana kudzera mu mphete ya pisitoni kupita ku khoma la silinda, ndipo 30 ~ 40% ya pisitoni yozizira imamwazikana kudzera mu mphete ya pistoni kupita ku silinda. khoma; Thandizo: Mphete ya pistoni imasunga pisitoni mu silinda, imalepheretsa kukhudzana kwachindunji pakati pa pisitoni ndi khoma la silinda, imawonetsetsa kuyenda bwino kwa pisitoni, imachepetsa kugundana, ndikuletsa pisitoni kugogoda silinda. Nthawi zambiri, pisitoni ya injini yamafuta imagwiritsa ntchito mphete ziwiri za gasi ndi mphete imodzi yamafuta, pomwe injini ya dizilo nthawi zambiri imagwiritsa ntchito mphete ziwiri zamafuta ndi mphete imodzi yamafuta.
