Makina onse ocheka maburashi opangidwa ndi gasi, makina otchetcha, zowulutsira ndi ma tcheni amagwiritsa ntchito injini ya pisitoni yomwe ndi yofanana kwambiri ndi yomwe imagwiritsidwa ntchito pamagalimoto.Pali kusiyana, komabe, makamaka pakugwiritsa ntchito ma injini amitundu iwiri mu macheka a unyolo ndi chodulira udzu.
Tsopano Tiyeni tiyambire pachiyambi ndikuwona momwe injini ziwiri zozungulira ndi zina zambiri zozungulira zinayi zimagwirira ntchito.Izi zidzakuthandizani kumvetsetsa zomwe zimachitika injini ikapanda kugwira ntchito.
Injini imapanga mphamvu poyatsa chisakanizo cha petulo ndi mpweya m'kachipinda kakang'ono kotchedwa chipinda choyaka moto, chomwe chikuwonetsedwa pachithunzichi.Mafuta osakaniza akamayaka, amatentha kwambiri ndipo amakula, monga mmene mercury mu thermometer imakula ndi kukankhira m’chubu pamene kutentha kwake kwakwera.”
Chipinda choyaka moto chimamatidwa mbali zitatu, kotero kuti kusakaniza kwa gasi wokulirakulira kumatha kukankhira njira imodzi yokha, kutsika pansi pa pulagi yotchedwa piston-yomwe imakhala yolowera pafupi ndi silinda.Kukankhira pansi pa pistoni ndi mphamvu yamakina.Tikakhala ndi mphamvu zozungulira, timatha kutembenuza tsamba la chodulira maburashi, tcheni chocheka, choulutsira chipale chofewa, kapena mawilo agalimoto.
Pakutembenuka, pisitoni imamangiriridwa ku crankshaft, yomwe imamangiriridwa ku crankshaft yokhala ndi zigawo zochotsera.Crankshaft imagwira ntchito ngati ma pedals ndi sprocket yayikulu panjinga.
Mukapalasa njinga, kutsika kwa phazi lanu pa pedal kumasinthidwa kukhala kuyenda kozungulira ndi shaft.Kuthamanga kwa phazi lanu ndi kofanana ndi mphamvu yomwe imapangidwa ndi kusakaniza kwa mafuta oyaka.Chopondapo chimagwira ntchito ya pisitoni ndi ndodo yolumikizira, ndipo chopondapo chimakhala chofanana ndi crankshaft.Chigawo chachitsulo chomwe silinda imabowoleredwa imatchedwa chipika cha injini, ndipo gawo lapansi lomwe crankshaft imayikidwa imatchedwa crankcase.Chipinda choyaka pamwamba pa silinda chimapangidwa mu chivundikiro chachitsulo cha silinda, chotchedwa mutu wa silinda.
Pamene pisitoni yolumikizira ndodo ikakamizika pansi, ndipo imakankhira pa crankshaft, imayenera kutembenukira uku ndi uku.Kuti alole kusuntha uku, ndodoyo imayikidwa muzitsulo, imodzi mu pisitoni, ina pamtunda wake wolumikizana ndi crankshaft.Pali mitundu yambiri ya mayendedwe, koma nthawi zonse ntchito yawo ndikuthandizira gawo lililonse losuntha lomwe lili ndi katundu.Pankhani ya ndodo yolumikizira, katunduyo amachokera ku pistoni yopita pansi.Chovalacho ndi chozungulira komanso chosalala kwambiri, ndipo gawo lomwe limalimbana nalo liyeneranso kukhala losalala.Kuphatikizika kwa malo osalala sikokwanira kuthetsa mikangano, kotero mafuta amayenera kulowa pakati pa kunyamula ndi gawo lomwe amathandizira kuti achepetse kukangana.Mtundu wodziwika kwambiri wonyamula ndi mawonekedwe osavuta, mphete yosalala kapena mwina zipolopolo ziwiri zomwe zimapanga mphete yathunthu, monga mu ll.
Ngakhale ziwalo zomangirira pamodzi zimawunikiridwa mosamala kuti zigwirizane bwino, kukonza kokha sikokwanira.Chisindikizo nthawi zambiri chimayikidwa pakati pawo kuti asatayike mpweya, mafuta kapena mafuta.Pamene chisindikizo ndi chinthu chathyathyathya, chimatchedwa gasket.Zida zodziwika bwino za gasket zimaphatikizapo mphira wopangira, cork, fiber, asibesitosi, zitsulo zofewa komanso zophatikizika izi.Gasket, mwachitsanzo, imagwiritsidwa ntchito pakati pa mutu wa silinda ndi chipika cha injini.Moyenera, amatchedwa cylinder head gasket.
Tsopano tiyeni tione mwatsatanetsatane ntchito yeniyeni ya injini ya petulo, yomwe ingakhale ya mitundu iwiri: kuzungulira kwa zikwapu ziwiri kapena sitiroko zinayi.
