Ukupakishwa kweembotyi zekofu akubonisi nje kuphela ubuhle bokubonakala, kodwa kukwasebenza kakuhle. Ukupakishwa okusemgangathweni ophezulu kunokuthintela ioksijini ngempumelelo kwaye kunciphise isantya sokuwohloka kwencasa yeembotyi zekofu.
Uninzi lweengxowa zekofu ziya kuba nesici esingqukuva, esifana neqhosha. Cinezela ibhegi, kwaye ivumba lekofu liya kugqojozwa ngomngxuma omncinci ongaphezulu "kweqhosha". Eli candelo lincinci elimile okweqhosha libizwa ngokuba "yivalvu yokukhupha umoya yendlela enye".
Iimbotyi zekofu ezisandula kuqhotswa zikhupha ikharbon diokside kancinci kancinci, kwaye okukhona irhasi imnyama, kokukhona ikhupha igesi yekharbon diokside ngakumbi.
Kukho imisebenzi emithathu yevalvu yokukhupha umoya yendlela enye: okokuqala, inceda iimbotyi zekofu zikhuphe umoya, kwaye kwangaxeshanye ithintele ukubola kweembotyi zekofu okubangelwa kukubuya komoya. Okwesibini, kwinkqubo yokuthutha, thintela okanye unciphise umngcipheko womonakalo wokupakisha obangelwa kukwanda kwengxowa ngenxa yokukhupha umoya kweembotyi zekofu. Okwesithathu, kwabanye abathengi abathanda ukuvumba ivumba, banokuva ivumba elimnandi leembotyi zekofu kwangaphambili ngokucinezela ingxowa yeembotyi.
Ngaba iingxowa ezingenayo ivalvu yokukhupha umoya ephuma kwicala elinye azifanelekanga? Akunjalo ngokupheleleyo. Ngenxa yezinga lokugcada iimbotyi zekofu, ukukhutshwa kwekhabhoni diokside nako kwahlukile.
Iimbotyi zekofu ezigcadiweyo ezimnyama zikhupha igesi eninzi yekhabhoni-diokside, ngoko ke kufuneka ivalvu yokukhupha umoya ephuma kwicala elinye ukuze incede igesi iphume. Kwezinye iimbotyi zekofu ezigcadiweyo ezikhaphukhaphu, ukukhutshwa kwekhabhoni-diokside akusebenzanga kangako, kwaye ukubakho kwevalvu yokukhupha umoya ephuma kwicala elinye akubalulekanga kangako. Yiyo loo nto, xa kusenziwa ikofu ethululwayo, iirosti ezikhaphukhaphu azinazo "izinto ezininzi" kuneembotyi ezigcadiweyo ezimnyama.
Ukongeza kwivalvu yokukhupha umoya yendlela enye, enye indlela yokulinganisa iphakheji zizinto zangaphakathi. Ukupakisha okusemgangathweni, umaleko wangaphakathi uhlala ufana nefoyile ye-aluminiyam. Ifoyile ye-aluminiyam inokuthintela ngcono ioksijini, ukukhanya kwelanga kunye nokufuma ngaphandle, idale imeko-bume emnyama yeembotyi zekofu.
