Mfundo yavalavu ya injini ya gasikwenikweni ndi kugwiritsa ntchito mphamvu ya injini kuwongolera kuyenda kwa gasi kudzera pamakina oyenera.Makamaka, valavu yamagalimoto pa mita ya mpweya imakhala ndi magawo awiri, imodzi ndi mota, ndipo inayo ndi valavu.
Yoyamba ndi mota, yomwe ndi gawo lofunikira kwambiri pamagetsi amagetsi amagetsi.Galimoto yamagetsi nthawi zambiri imakhala ndi magawo awiri okhala ndi ntchito zosiyanasiyana: mota ndi radiator.Gasi yamagetsi yamagetsi ndiye gwero lamphamvu la valve yamagetsi yamagetsi.Ikhoza kutembenuza mphamvu yamagetsi kukhala mphamvu yamakina ndikuwongolera valavu pozungulira shaft.Radiyeta imachotsa bwino kutentha kwa injini kuti iteteze kuwonongeka kwa dera komwe kumachitika chifukwa cha kutenthedwa kwa injini pambuyo pogwira ntchito kwanthawi yayitali.Chifukwa chake, valavu yamagetsi yamagetsi yamagetsi yamagetsi siyenera kukhala ndi mphamvu zokha, komanso kukhala ndi zotsatira zabwino zotaya kutentha.
Chotsatira ndi valavu.Ntchito ya valavu ndikuwongolera kayendetsedwe ka kayendedwe ka gasi ndi kutuluka kwa mpweya, kuphatikizapo kutsegula ndi kutseka njira ya gasi.Mavavu amagetsi amagetsi amagetsi amaphatikizanso ma valve a mpira, mavavu a pachipata, ma valve agulugufe, ndi zina zambiri. Mavavu amagetsi amamita gasi nthawi zambiri amakhala ndi kukana dzimbiri, kukana kutentha kwambiri komanso kusindikiza bwino.
Mwa kuphatikiza mota ndi valavu, kuwongolera gasi kumatha kukwaniritsidwa.Pakafunika mpweya, makinawa amatsegula valavu yamagalimoto ndikuyendetsa mpweya mu zida za gasi kuti akwaniritse zofunikira.Pamene palibe chifukwa chogwiritsira ntchito gasi, dongosololi lidzatseka valavu yamoto ndikuyimitsa kutuluka kwa gasi, motero kupewa mavuto monga kutuluka kwa mpweya ndi zinyalala.
Mwachidule, mfundo ya valavu yamagetsi yamagetsi ndi kugwiritsa ntchito kuyendetsa galimoto ndi kulamulira kwa valve kuti mukwaniritse kasamalidwe koyenera komanso kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, kuyenda ndi kugwiritsa ntchito mpweya.Izi sizimangotsimikizira kugwiritsa ntchito gasi motetezeka, moyenera, komanso kupulumutsa mphamvu komanso kumapangitsa kuti mpweya ukhale wabwino komanso upangiri wabwino.
