Hlakulela imikhuba emihle yokushayela futhi uhlole izinga likawoyela njalo. Izinga eliphezulu lamafutha ngeke likhulise ukumelana kwenjini ngesikhathi sokusebenza, okubangela ukulahlekelwa kwamandla okungadingekile, kodwa futhi kubangele ukuvuza kwamafutha; izinga eliphansi likawoyela lizolimaza injini ngenxa yokungagcobi kahle. Ngakho-ke, uma izinga likawoyela wenjini liphansi kakhulu, hlola ukuthi ingabe injini inokuvuza kukawoyela kanye nokusetshenziswa kukawoyela ngendlela engavamile; vula inkinobho yokushisa ngaphambi kokuqala injini, futhi inkomba yezinga likawoyela kanye nenkomba yengcindezi kawoyela iyakhanya, futhi kufanele baphume ngemva kokuqala injini.
Sebenzisa amafutha ane-viscosity efanele. Uma i-viscosity yamafutha iphansi kakhulu, ifilimu yamafutha ilimala kalula futhi izingxenye zinamathele; uma i-viscosity iphezulu kakhulu, ukumelana okwengeziwe kokunyakaza kwezingxenye kuzokwenziwa, okwenza kube nzima ukuqala injini nokwandisa ukulahlekelwa kwamandla. Ngakho-ke, lapho ushintsha amafutha, bheka i-viscosity enconywe umenzi encwadini yomshayeli ngangokunokwenzeka.
(1) Khetha uwoyela ngokwesimo sezulu
Uma izinga lokushisa le-ambient liphansi, khetha amafutha ane-viscosity ephansi ukuze kube lula ukuqala kwenjini. Uma izinga lokushisa elizungezile liphezulu, khetha amafutha ane-viscosity ephakeme ukuze kube lula ukunyakaza nokugcina ifilimu yamafutha;
(2) Khetha uwoyela ngokwesimo semoto
Izinjini ezisesimweni esihle, imvume incane, ngakho-ke kungasetshenziswa uwoyela one-viscosity ephansi. Ezinjini ezisesimweni esibi, imvume inkulu, ngakho-ke amafutha ane-viscosity ephakeme angasetshenziswa;
(3) Sebenzisa amafutha akhethekile
Ngenxa yomfutho ovuthayo wezinjini zikadizili kanye nesibabule{0}}esiqukethe udizili sikhiqiza uwoyela oyi-sulfurous diluent ngemva kokusha, izinjini zikadizili kufanele zisebenzise uwoyela okhethekile ezinjinini zikadizili ezinganciphisa i-asidi eyi-sulfurous.
(4) Ukusetshenziswa okunengqondo kwemikhiqizo yokulungisa injini yemoto
Thuthukisa ukusebenza kokugcoba kwenjini, gwema ukuguga kwenjini, bese ushintsha ukukhanda ngokulungiswa.
Shintsha njalo uwoyela wenjini, sebenzisa{0}imikhiqizo yokunakekela injini yekhwalithi ephezulu ukuze ilungiswe, uhlanze njalo udaka, i-colloid ne-carbon deposits ngaphakathi kwesistimu yokuthambisa injini, ugcine isistimu yokuthambisa ihlanzekile, futhi usebenzise imikhiqizo yokuvikela injini ukuze uthuthukise ngempumelelo ukusebenza kokugcotshwa kwengxenye ngayinye, unciphise ukuguga, futhi ukhulise impilo yesevisi yezingxenye.
Ohlelweni lokugcotshwa kwenjini yezimoto, inqobo nje uma kwenziwa ukugcinwa okuvamile, akukwazi nje ukunweba impilo yesevisi yenjini, kodwa futhi kunciphise ukulahlekelwa kwezomnotho okungadingekile.
(5) Ukuhlanza umzila kawoyela
Indlela yokuhlanza yilena: ngemva kokuba uwoyela udoti usuphelile, jova uwoyela omncane noma ohlungiwe udizili ophezulu-wezinga eliphezulu epanini likawoyela wenjini, inani lalo elilingana no-60% -70% wezinga lamafutha elijwayelekile epanini likawoyela, bese ugijima injini ngesivinini esingenzi lutho imizuzu engu-2-3, bese ukhipha uwoyela wokuwasha.
