Izikhwama zekhofi ziyindlela edumile yokugcina nokuthutha ubhontshisi wekhofi. Afika ngosayizi nezitayela ezahlukene, futhi asetshenziswa abarosa ikhofi, abasabalalisi, nabathengisi ukupakisha ubhontshisi wekhofi ukuze adayiselwe abathengi.
Esinye sezizathu eziyinhloko zokuthi kungani izikhwama zekhofi zisebenza kahle kakhulu ekugcineni ubhontshisi wekhofi uhlanzekile kungenxa yezinto ezenziwe ngazo. Ngokuvamile, izikhwama zekhofi zenziwe ngenhlanganisela yepulasitiki, i-aluminium, nephepha. Isendlalelo sepulasitiki sinikeza isithiyo kumswakama nomoya, kuyilapho ungqimba lwe-aluminium lunikeza umgoqo wokukhanya nomoya-mpilo. Isendlalelo sephepha sinikeza isakhiwo sesikhwama futhi sivumela ukubeka uphawu nokulebula.
Ukuhlanganiswa kwalezi zinto kudala indawo eyingqayizivele yamabhontshisi wekhofi ngaphakathi kwesikhwama. Ungqimba lwepulasitiki luvimbela umswakama ukuthi ungangeni, okungabangela ubhontshisi wonakale noma ukhuntile. Isendlalelo se-aluminium sivimbela ukukhanya nomoya-mpilo ukuthi kungangeni, okungabangela ubhontshisi ukuba u-oxidize futhi ulahlekelwe ukunambitheka.
Ngaphezu kwezinto ezisetshenziswa ezikhwameni zekhofi, ezinye izikhwama nazo zine-valve yendlela eyodwa. Le valve ivumela i-carbon dioxide, ekhiqizwa ubhontshisi wekhofi phakathi nenqubo yokugazinga, ukuba iphume esikhwameni kuyilapho ivimbela umoya-mpilo ukuba ungangeni esikhwameni. Lokhu kubalulekile ngoba umoya-mpilo ungabangela ubhontshisi ukuba uphelelwe yisikhathi futhi ulahlekelwe ukunambitheka kwawo.
Izikhwama zekhofi nazo ziza ngosayizi abahlukene, okuvumela ukuthi ubhontshisi wekhofi uhlanganiswe ngamanani amancane. Lokhu kubalulekile ngoba uma isikhwama sekhofi sesivuliwe, ubhontshisi uqala ukulahlekelwa ubusha bawo. Ngokupakisha ubhontshisi ngamanani amancane, abaphuza ikhofi bangaqinisekisa ukuthi bahlala besebenzisa ubhontshisi omusha.
Sengiphetha, izikhwama zekhofi ziyindlela ephumelelayo yokugcina ubhontshisi bekhofi bemusha ngenxa yezinto ezenziwe ngazo, i-valve yendlela eyodwa evumela ukuphuma kwe-carbon dioxide, kanye nekhono lokupakisha ubhontshisi ngamanani amancane. Ngokusebenzisa izikhwama zekhofi, abarosa ikhofi, abasabalalisi, nabathengisi bangaqinisekisa ukuthi amakhasimende abo athola ikhofi elisha kakhulu ngangokunokwenzeka.
