Ekubeni isityalo sokuxuba i-asphalt esisetyenzisiweyo sathengwa ngokukhawuleza, inkqubo yokutshisa kunye nokomisa kwayo inokuhlangabezana kuphela neemfuno zokutsha kwe-diesel. Nangona kunjalo, njengoko ixabiso le-diesel linyuka, ukusebenza kakuhle kwezoqoqosho ekusebenziseni izixhobo kuya kuba ngaphantsi nangaphantsi. Kule nkalo, abasebenzisi banethemba lokuba inokusombulula ngokuguqula inkqubo yokutsha yezityalo zokuxuba i-asphalt. Ziziphi izicombululo ezisengqiqweni iingcali ezinazo koku?
Ukuguqulwa kwenkqubo yokutshisa isityalo sokuxuba i-asphalt ikakhulu kubandakanya le miba ilandelayo. Eyokuqala kukutshintshwa kwesixhobo sokutsha, endaweni yompu wokutshiza wedizili wokuqala ngompu wokutshiza onzima kunye nedizili eneenjongo ezimbini. Esi sixhobo sifutshane kwaye asifuni ukujika kweengcingo zokufudumeza zombane.

Into ephambili kukuba ayiyi kuvalwa ngeoli enzima eseleyo, evumela ukuba ioli enzima itshiswe ngokupheleleyo kwaye inciphise ukusetyenziswa kweoli eninzi.
Isinyathelo sesibini kukuguqula itanki ye-diesel yangaphambili kwaye ubeke i-coil yeoli ye-thermal ezantsi kwetanki ukuze isetyenziswe ukufudumeza i-oyile enzima kwiqondo lokushisa elifunekayo. Kwangaxeshanye, ikhabhinethi yolawulo yombane eyahlukileyo kufuneka isekwe ukuze yonke inkqubo iqonde ukutshintshela ngokuzenzekelayo phakathi kwedizili kunye neoyile enzima, kunye nokukhusela inkqubo ngeealam ezivakalayo nezibonakalayo.
Enye inxalenye kukuphuculwa kwesithando somlilo se-oyile, kuba isithando somlilo esivuthayo esatshisa idizili sasisetyenziswa ekuqaleni. Ngeli xesha, yatshintshwa isithando somlilo esivuthayo ngamalahle, esinokonga kakhulu iindleko.
