Nangona kuphela "isakhiwo se-ontology", ukusebenza kakuhle kobushushu be-51.09% kusenza abantu bazive ikamva leenjini zedizili. Ukuba akubangakho ngenxa yezizathu ezibini zokuthintelwa kokukhutshwa kwekhabhoni kunye noovimba bobuchule bedizili obucwangcisiweyo, iinjini zedizili kufuneka zibe nethemba elihle kakhulu. Ukusebenza kwe-thermal ngumlinganiselo wamandla omsebenzi. Okukhona kuphezulu ukusebenza kakuhle kwe-thermal, ngakumbi umsebenzi. Ukusebenza kwe-injini kunye nokusebenza kakuhle kwe-thermal ye-35% kunye nokusebenza kakuhle kwe-thermal ye-45% kwahluke ngokupheleleyo.

Ukusebenza kakuhle kwe-thermal yeenjini zepetroli okwangoku kumalunga nama-40% kuphela, kwaye ukusebenza ngokufanelekileyo kobushushu kwixesha elidlulileyo bekumalunga nama-35%. Kwiminyaka yakutshanje, utyalo-mali olunamandla kuphando kunye nophuhliso luphucule kakhulu ukusebenza kakuhle kwe-thermal, kodwa ukusebenza akukabi kuhle.

Ngenxa yeenzuzo zesakhiwo, ii-injini zedizili zenza ukutsha ngokupheleleyo ngokucinywa komlilo, kunye neempawu zokutsha kwe-homogeneous zenza ukutsha ngokupheleleyo. Ke ngoko, ukusebenza kakuhle kwe-thermal yezithuthi zamafutha ngokuqhelekileyo ku-5% -10% ephezulu kuneenjini zepetroli.
