1. Umsebenzi wesistimu yokukhiya umnyango ophakathi
Imisebenzi ehlukahlukene yesikhiya sokulawula esimaphakathi isekelwe emisebenzini yokukhiya okujwayelekile okufanele kufinyelelwe, ngakho kufanele siqale siqonde futhi siqonde imisebenzi nezici zokukhiya okujwayelekile.
(1) Ilokhi evamile
Umsebenzi wokukhiya okujwayelekile umqondo ojwayelekile wokuvula nokukhiya umsebenzi, okuwukunikeza izinhlangothi zombili zomnyango wemoto, ikhava ye-trunk (noma isicabha somsila) umsebenzi wokuvula nokukhiya.
Ibonakala ngokusetshenziswa okulula nokuxhumanisa iminyango eminingi.Kuwukucushwa okujwayelekile kohlelo lokukhiya lokulawula okumaphakathi, kanye nemfuneko yokufeza imisebenzi ehlobene yohlelo lokukhiya lokulawula olumaphakathi kanye nohlelo olusebenzayo lokulwa nobugebengu.
Umsebenzi wokukhiya ojwayelekile waziwa nangokuthi umsebenzi wokukhiya okuphindwe kabili, ngesisekelo lapho umsebenzi wokukhiya kabili uklanywe khona.Okusho ukuthi, ngemuva kokuvala ukukhiya okujwayelekile, injini yokukhiya izohlukanisa isibambo somnyango kumshini wokukhiya, ukuze umnyango ungavulwa emotweni ngokusebenzisa isibambo somnyango.
Qaphela: Umsebenzi wokukhiya kabili uwukufaka ukhiye wokukhiya ngokhiye, bese uvula indawo yokukhiya kabili phakathi kwemizuzwana emithathu;Noma inkinobho yokukhiya kusilawuli kude icindezelwe kabili phakathi nemizuzwana emithathu;
Uma imoto ikhiywe kabili, isignali yokujika iyakhanya ukuze iqinisekise
