I-liner yangaphakathi yetanki yokugcina i-oksijeni yolwelo yenziwe nge-16MnDR kunye ne-liner yangaphandle ye-tank yokugcina i-oksijini engamanzi yenziwe nge-Q245R okanye i-Q345R. Indawo yokugcina i-oksijini yolwelo ikhetha "umdibaniso, i-valve yenkqubo yokhuseleko" isebenzisa amaqela amabini eevalvu zokhuseleko ukuze isebenze kunye, ngexesha lokulinganisa ivalve yokhuseleko inokuvalwa kwelinye icala, ukuya kwelinye icala lokugcinwa kweoksijini ekhuselekileyo.
