Ntchito ya Zosefera Air

Zochita Injini iyenera kuyamwa mpweya wambiri panthawi yogwira ntchito.Ngati mpweya sunasefedwe, fumbi loyimitsidwa mumlengalenga limayamwa mu silinda, zomwe zidzafulumizitsa kuvala kwa gulu la pistoni ndi silinda.Tinthu tating'onoting'ono tomwe timalowa pakati pa pisitoni ndi silinda imatha kuyambitsa "kukoka silinda", komwe kumakhala koopsa kwambiri m'malo owuma komanso amchenga.Thempweya fyulutaimayikidwa kutsogolo kwa carburetor kapena chitoliro cholowetsa, ndipo imagwira ntchito yosefa fumbi ndi mchenga mumlengalenga, kuti zitsimikizire kuti mpweya wokwanira ndi woyera umalowa mu silinda.

Pakati pa zikwizikwi za magalimoto, ndimpweya fyulutandi gawo losaoneka bwino, chifukwa siligwirizana mwachindunji ndi luso la galimoto, koma pakugwiritsa ntchito galimotoyo, fyuluta ya mpweya ndiyofunika kwambiri pagalimoto.Moyo wautumiki (makamaka wa injini) umakhudza kwambiri.Kumbali imodzi, ngati palibe kusefa kwa fyuluta ya mpweya, injiniyo imakoka mpweya wambiri wokhala ndi fumbi ndi tinthu tating'onoting'ono, zomwe zimapangitsa kuti silinda ya injini iwonongeke kwambiri;Kumbali ina, ngati fyuluta ya mpweya siyikusungidwa kwa nthawi yayitali pakugwiritsa ntchito, fyuluta ya mpweya The fyuluta yotsukira imakhala yodzaza ndi fumbi mumlengalenga, zomwe sizimangochepetsa mphamvu zosefera, komanso zimalepheretsa kufalikira. mpweya, zomwe zimabweretsa kusakaniza kolemera kwambiri ndipo injini siigwira ntchito bwino.Choncho, kukonza nthawi zonse fyuluta ya mpweya ndikofunikira.

Pali mitundu iwiri ya zosefera mpweya: mapepala ndi mafuta osamba.M'zaka zaposachedwa, zosefera zamapepala zakhala zikugwiritsidwa ntchito kwambiri chifukwa cha zabwino zake zosefera kwambiri, kulemera kwake, kutsika mtengo, komanso kukonza kosavuta.Kuchita bwino kwa kusefera kwa chinthu chosefera pamapepala ndikokwera mpaka 99.5% kapena kupitilira apo, ndipo kusefera kwamafuta osambira amafuta ndi 95-96% munthawi yake.Pakalipano, fyuluta ya mpweya yomwe imagwiritsidwa ntchito kwambiri m'galimoto ndi fyuluta ya pepala, yomwe imagawidwa m'mitundu iwiri: mtundu wouma ndi wonyowa.Pazinthu zowuma zosefera, zikamizidwa mumafuta kapena m'madzi, kukana kusefera kumawonjezeka kwambiri, choncho pewani kukhudzana ndi madzi kapena mafuta poyeretsa, apo ayi magawo atsopano ayenera kusinthidwa.

Injini ikamathamanga, mpweya wolowa umakhala wapakatikati, zomwe zimapangitsa kuti mpweya wa m'nyumba zosefera mpweya uzigwedezeka.Kuthamanga kwa mpweya kumasinthasintha kwambiri, nthawi zina kumakhudza mpweya wa injini.Kuphatikiza apo, nthawi ino idzawonjezeranso phokoso lakudya.Pofuna kupondereza phokoso lakumwa, kuchuluka kwa nyumba zosefera mpweya kumatha kuonjezedwa, ndipo magawo ena amakonzedwanso kuti achepetse resonance.

Zosefera za fyuluta ya mpweya zimagawidwa m'mitundu iwiri: chigawo chowuma ndi fyuluta yonyowa.Zowuma zosefera ndi pepala losefera kapena nsalu yopanda nsalu.Pofuna kuwonjezera malo olowera mpweya, zinthu zambiri zosefera zimakonzedwa ndi makwinya ang'onoang'ono.Choseferacho chikadetsedwa pang'ono, chimatha kutsukidwa ndi mpweya woponderezedwa.Zosefera zikadetsedwa kwambiri, ziyenera kusinthidwa ndi zatsopano pakapita nthawi.
