Kugwiritsa ntchito

Imagwiritsidwa ntchito makamaka pamakina komanso kupanga ma cylinders a gasi, kuphatikiza machubu a kaboni ndi aloyi opanda makina osasunthika, ndipo amakwirira machubu amakina osasunthika komanso oziziritsa komanso osaziziritsa omwe amamaliza kuzizira mpaka kukula kwake ndi kuphatikiza 12 3⁄4 mu. (323.8 mm) kunja kwake kwa machubu ozungulira okhala ndi makulidwe a khoma ngati pakufunika.
