P2: Ke hobane'ng ha ho hlokahala bonete e atolositsoeng bakeng sa li-valve tsa bolo tse mocheso o phahameng?
Bonnete e atolositsoeng e suthisa lebokose la ho paka la kutu hole le mmele wa phaephe e chesang, e fedisa mocheso o kganyang. Sena se boloka ditiiso tsa kutu (tse kang graphite e tenyetsehang) di le kahare ho mocheso wa tsona o bolokehileng wa tshebetso, se thibela ho senyeha ha mocheso, mme se sireletsa di-actuator tsa motlakase kapa tsa moya hore di se ke tsa chesa haholo.
