1. Phokoso lochepa
Kulumikizana pakati pa chipolopolo chonyamula ndi crankshaft ndi chachikulu, kupanikizika kwapakati kumakhala kochepa, ndipo pali filimu yokwanira yamafuta, kotero kuti ntchitoyi siili yosalala komanso yotsika phokoso. Mipira yachitsulo mkati mwa chotengera mpira idzatulutsa phokoso lalikulu pakuyenda.
2. Small kukula ndi unsembe yabwino
Crankshaft ili ndi mawonekedwe apadera, zomwe zimapangitsa kuti zikhale zovuta kuti ma fani ena awoloke pa crankshaft ndikuyika pamalo oyenera. Zipolopolo zokhala ndi zosavuta kuziyika ndikukhala ndi malo ochepa, zomwe zimathandiza kuchepetsa mphamvu ya injini.


3. Angapereke mlingo wina wa ufulu wa axial
Chifukwa crankshaft idzakula chifukwa cha kutentha panthawi yogwira ntchito, zomwe zimapangitsa kuti pakhale kusuntha kwina kwa axial. Kwa mayendedwe a mpira, mphamvu ya axial imatha kupangitsa kuvala kwa eccentric, komwe kungayambitse kulephera kubereka msanga, ndipo zipolopolo zonyamula zimakhala ndi ufulu wochulukirapo polowera mbali ya axial.
4. Malo akuluakulu okhudzana ndi kutentha kwachangu
Malo olumikizirana pakati pa chipolopolo chonyamulira ndi crankshaft magazine ndi yayikulu, ndipo mafuta a injini amazungulira mosalekeza ndikupaka mafuta pakagwira ntchito. Kuphatikiza apo, mafuta ochulukirapo amayenda pamtunda wolumikizana, omwe amatha kuchotsa kutentha kwambiri ndikuwongolera kukhazikika kwa injini.
