Zipangizo zoyesera zapamwamba zimagwiritsidwa ntchito kutsimikizira kulondola ndi kulimba kwa camshaft, ndikutsimikizira magwiridwe antchito odalirika kwa nthawi yayitali. Pokhala ndi kudzipereka ku zatsopano ndi kudalirika, B15 camshaft ndi gawo lofunikira kwambiri pakukweza magwiridwe antchito ndi magwiridwe antchito a injini.
Camshaft yathu imapangidwa ndi chitsulo chozizira, Chitsulo chozizira chimakhala ndi kuuma kwambiri komanso kukana kuvala, zomwe zimapangitsa kuti camshaft ikhale ndi moyo wautali. Mphamvu yake yabwino kwambiri yotopa imalola kuti ipirire kutopa kwambiri. Zipangizozi zimaperekanso kutentha bwino, kuchepetsa chiopsezo cha kutentha kwambiri. Kuphatikiza apo, pamwamba pa camshaft ya B15 imapukutidwa, zomwe zimapangitsa kuti pamwamba pake pakhale bwino komanso kuchepetsa kukangana. Izi zimapangitsa kuti magwiridwe antchito ndi magwiridwe antchito azikhala bwino. Malo opukutidwawo amathandizanso kupewa kuwonongeka msanga ndikuwonjezera moyo wa camshaft.
Pa nthawi yopanga, camshaft imapangidwa pogwiritsa ntchito makina a CNC olondola kwambiri, zomwe zimatsimikizira kulondola ndi kusasinthasintha. Gawo lililonse limawunikidwa mosamala pazigawo zosiyanasiyana zopangira kuti zitsimikizire kuti likukwaniritsa miyezo yokhwima yowongolera khalidwe.
