Zotsatira

Motsogozedwa ndi lamba wanthawi kapena unyolo wanthawi, camshaft imayendetsa valavu kuti itsegule ndi kutseka nthawi yoyenera, ndikugwirizana ndi pisitoni kuti amalize njira zinayi zotengera mpweya, kuponderezana, kugwira ntchito ndi kutulutsa mpweya. Chifukwa lamba wa nthawi ndi unyolo wa nthawi zidzalumphira pakatikati komanso kuthamanga kwambiri, ndipo lamba wa nthawiyo adzatambasulidwa ndi kupunduka chifukwa cha zinthu ndi mphamvu ya lamba pakugwiritsa ntchito nthawi yayitali, zomwe zimapangitsa kuti pakhale nthawi yolakwika ya gasi. Izi zidzapangitsa kuti galimotoyo iwononge gasi, kufooka, kugogoda ndi zolakwika zina. Pakakhala mano ambiri odumphira, injini imawonongeka chifukwa cha kugunda kwa valve ndi pistoni yokwera chifukwa valavu imatsegulidwa mofulumira kwambiri kapena kutsekedwa mochedwa kwambiri.

Pofuna kusunga lamba wa nthawi ndi nthawi yokhazikika pazovuta zoyenera, ndiye kuti, sangalumphe chifukwa cha kumasuka kwambiri ndipo sadzawonongeka chifukwa cha kupsinjika kwakukulu. Pali tensioning dongosolo wapadera wopangidwa tensioner ndi tensioner kapena njanji zikuchokera. The tensioner amapereka kukakamiza kwa lamba kapena unyolo. Wothandizira amalumikizana mwachindunji ndi lamba wanthawi, ndipo njanji yowongolera imalumikizana mwachindunji ndi unyolo wanthawi. Amagwira ntchito ndi lamba kapena unyolo pamene akugwiritsa ntchito mphamvu zomwe zimaperekedwa ndi tensioner pa izo. , Kuti asunge mlingo woyenera wa tension.The tensioner amachita pa lamba wa nthawi kapena nthawi ya injini kuti atsogolere ndikuyimitsa kuti nthawi zonse ikhale yabwino kwambiri. Nthawi zambiri amagawidwa m'njira ziwiri: ma hydraulic ndi makina, onse omwe amatha kusintha kukhazikika kwa lamba wanthawi ndi unyolo wanthawi.
