Kudzikira-kupisa kupisa ndiyo sulfur dioxide uye sulfur trioxide inogadzirwa nesarufa mumafuta panguva yekupisa mucylinder, ese ari magasi, anosanganiswa nemvura kugadzira hyposulfuric acid uye sulfuric acid (apo cylinder wall tembiricha iri. yakadzikira pane dova radzo), zvichigadzira ngura yekudzikira. .

Kana iyo yakazara base nhamba yecylinder oiri yakadzikira, pendi-yakafanana nedhipoziti ichaonekwa pamusoro peiyo silinda liner pakati pega yega jekiseni remafuta, uye pamusoro peiyo silinda liner pasi pependi-yakafanana chinhu ichasvibiswa nekuora. . Kana chrome-plated cylinder liners inoshandiswa, mavara machena (chromium sulfate) achaonekwa munzvimbo dzakasvibiswa.

Zvinhu zvinokanganisa kudzikira kwekushisa kwekushisa ndeye sulfur iri mumafuta emafuta, kukosha kwealkali uye mwero wejekiseni remafuta mucylinder oiri, uye mvura irimo mugasi rekutsvaira. Hunyoro hwemhepo inofefetera hunoenderana nehunyoro hwemhepo uye tembiricha yemhepo.

Apo ngarava inofamba munzvimbo yegungwa ine hunyoro hwepamusoro, teerera kutarisa kubuda kwemvura yakasvibiswa yemhepo inotonhorera.

Kugadzika kwekushisa kwekupomba kune huviri. Iyo yakadzika tembiricha inogona kuita basa re "dry cooling" scavenging, hunyoro hwemhepo hwekutsvaira huchadzikira, uye simba reinjini huru richawedzera; zvisinei, yakaderera scavenging mhepo tembiricha kuchakanganisa tembiricha humburumbira rusvingo. Kamwe tembiricha yehumburumbira yemadziro yakadzikira pane dova, kupisa kwakadzika kunoitika kana kukosha kweiyo cylinder mafuta firimu pamadziro cylinder haina kukwana.

Iyo inotaurwa mune huru injini sevhisi denderedzwa kuti kana injini huru ichimhanya pamutoro wakaderera, inokurudzirwa kuti iwedzere tembiricha yekutsvaira kudzivirira yakaderera tembiricha ngura.

Kuwedzera tembiricha yeinjini huru silinda liner yekutonhodza mvura kuti ideredze tembiricha yakaderera, MAN ashandisa iyo LCLL system kuwedzera mainjini silinda liner inotonhorera mvura kusvika 120 °C kudzivirira kushomeka kwekushisa.
