Tare da m halaye na damping

A cikin mafita na zamani, abin da ake kira ingin mai aiki yana hawa, wanda ke da alamun damping masu canzawa. Hanya ɗaya ita ce amfani da injin lantarki. Yana ba ku damar daidaita matakin damping zuwa yanayin tuƙi na yanzu ko yanayin tuƙi da aka zaɓa na mai amfani, da kuma sarrafa yanayin yanayin damping mara daidaituwa (wannan yana da mahimmanci musamman a cikin layin-Silinda guda uku). injuna).

Kishiyar wannan hanyar ita ce kushin ɗora motoci tare da nau'ikan aiki guda biyu (maimakon injin lantarki). Abubuwan da ake kira laushi masu laushi na matashi ana jin su kawai a rago. Bi da bi, a lokacin motsi na mota, girman damping ƙarfi ne m da kuma daidai da halin yanzu oscillation na engine.
