Sisiphi isizathu sokushisa okuphezulu kwinqanaba le-convection ye ityhubhu yomlilo kunakwicandelo elikhazimlayo?

Ukushisa kwecandelo lokudibanisa kwesithando somlilo liphezulu kunelo candelo elikhanyayo kuba icandelo le-convection linomoya owaneleyo kunye nokutsha okwaneleyo; icandelo elikhanyayo livutha kakubi, kwaye inxalenye yepetroli (ioli) ivutha ngokungagqibekanga kwaye ibe yi-carbon monoxide kunye ne-carbon particles.
