Iimpawu zesilumkiso: "Ukukhetha" i-tinking ", njengokuhamba ngesando esincinci ukutyhila umgangatho onzima, kuvakala kwindawo ye-cranksest; Oku kubandakanya ukuba "nge-cylinder enkqonkqozayo." Uvavanyo lwe-oyile ihla, libhengezwe ngakumbi ngexesha lokukhawulezisa ngokukhawuleza. I-cylinder enkqonkqozayo sisilele esitshabalalisi soomatshini, ikakhulu sibangelwa kukudibanisa okukhulu kwe-bolts okanye imbambano enkulu kwi-bolt right, ekhokelela ekucacisweni kakhulu kwi-shalts eqhagamshelwe okanye ekhulisa. Ukuba inkqonkqoza ikhoyo kodwa uxinzelelo lwe-oyile luqhelekile, ayisilomqondiso wokunkqonkqoza isilinda; Umcimbi kufuneka uthathwe uqwalaselwe ngokuhlengahlengiswa kwexesha lokuphononongwa kwefutha.

Amanyathelo okulungisa: Yiyeke kwangoko i-injini yokuhlolwa kunye nokulungisa, ukutshintsha naliphi na inxenye ephosakeleyo.
