①Kuita kusefa kwemhepo sefa kwakaderedzwa.
Basa resefa yemhepo kusefa huruva nezvimedu zvinobva mumhepo. Kana mota ichityaira, mhepo iri munzira inongove ine huruva nezvimedu, uye kana zvimedu izvi zvakayamwa mucylinder muhuwandu hukuru, zvinokonzeresa kusakara kwakakomba pamusoro pehumburumbira. Kana nzvimbo yemugwagwa yakaoma, guruva riri mumhepo mumugwagwa wakanaka 0 01g /m3, guruva remhepo mumugwagwa wevhu 0 45g //m3. Tevedzera mamiriro emotokari inotyaira mumigwagwa ine tsvina uye kuitisa dhiziri injini bhenji bvunzo, nekunyepedzera ichibvumira injini yedhiziri kufemesa guruva remukati mwero we0 Mushure mekushanda kwemaawa 25-100 chete ne5g //m3 yemhepo, muganho wekupfeka. yehumburumbira inogona kusvika 0 3-5 mm. Kubva pane izvi, zvinogona kuoneka kuti kuvapo kana kusavapo kwesefa yemhepo uye mhedzisiro yekusefa zvinhu zvakakosha zvinotaridza hupenyu hwebasa rehumburumbira.
② Iko kusefa kwemafuta sefa haina kunaka.
Pamusana pekusachena kwemafuta ejini, mafuta ane huwandu hwakawanda hwezvimedu zvakaoma zvichange zvisingadzivisiki zvinokonzera kupera kwemukati mukati me cylinder kubva pasi kusvika kumusoro.

③Hunhu hwemafuta ekuzora hauna kunaka.
Kana iyo sulfur yemukati yemafuta ekuzora anoshandiswa muinjini dzedhiziri yakakwira zvakanyanya, zvinokonzeresa kuparara kwakasimba kwemhete yekutanga yepiston panzvimbo yepamusoro yakafa, zvichikonzera kupera kwekuora. Huwandu hwekupfeka hunowedzera ne 1-2 nguva kana ichienzaniswa neyakajairwa kukosha, uye zvimedu zvakanyungudutswa nekupfeka zvinoparadza zvinogona kukonzera kwakashata abrasive kupfeka pakati pehumburumbira.
④ Mota dzakaremerwa, dzinomhanyisa, uye dzinoshanda pasi pemitoro inorema kwenguva yakareba. Kupisa kweinjini yedhiziri kunokanganisa kuita kwekuzora.
⑤ Tembiricha yemvura yeinjini yedhiziri yakadzikira zvakanyanya kuti ichengetedze tembiricha yemvura yakajairika, kana thermostat inobviswa mapofu.
⑥ Kumhanya munguva ipfupi, uye mukati mehumburumbira yakaoma.
⑦ Iyo cylinder ine unhu husina kunaka uye yakaderera kuoma.
