Ukuhlelwa kobungqina bokudubula: Inqanaba le-IIC lelona liphezulu, equka izicelo ze-IIB kunye ne-IIA; I-IIB igqithile kwi-IIA ngokwenqanaba.

Ubushushu bomphezulu obuninzi: Oku kubhekiselele kwelona qondo lobushushu liphezulu ezinokufikelelwa zizixhobo zombane phantsi kwezona meko zimbi kakhulu zokusebenza, okunokubanakho ukuvuthisa umoya ongqonge woqhushumbo. Ubushushu obuphezulu bomphezulu kufuneka bube ngaphantsi kunobushushu obunokutsha.

Njengokuba: Kwiindawo apho kusetyenziswa abenzi boluvo bokuthintela uqhushumbo, ukuba ubushushu bomlilo we qhuma iigesi yi-100°C, ke ubushushu obuphezulu bomphezulu walo naliphi na icandelo lenzwa kufuneka lihlale lingaphantsi kwe-100 ° C.
