Ingcaciso yeMveliso:
I-injini engundoqo inezikrufu ezibini eziphakamileyo, izikrufu zokukhokela ezibini, kunye nesilinda esisezantsi. Indawo yokuqina ibekwe ngasentla kwenjini ephambili, kwaye indawo yovavanyo yoxinzelelo kunye nokugoba ibekwe phakathi komqadi osezantsi we-injini ephambili kunye nebhentshi yokusebenza. Isixhobo sokulinganisa amandla samkela isiboniso sekristale yolwelo olukwingcaciso ephezulu, kwaye idatha yovavanyo ifanelekile kwaye iyaqondakala.
