(1) Lapho ulungisa, qinisekisa izinga lomhlangano

Lapho uhlanganisa i-crankshaft yenjini ye-diesel, zonke izinyathelo kufanele ziqonde. Ngaphambi kokufaka i-crankshaft, hlanza i-crankshaft bese uhlanza iphasishi likawoyela we-crankshaft ngomoya onengcindezi ephezulu. Amanye ama-crankshaft anezimbobo eziseceleni futhi avinjwe ngezikulufo. Ukungcola okuhlukanisiwe kuwoyela ngenxa yamandla e-centrifugal kuzonqwabelana lapha. Susa izikulufu futhi uzihlanze ngokucophelela.

Lapho uhlanganisa i-crankshaft, kuyadingeka ukukhetha ama-bearings aphezulu futhi abe sezingeni elifanayo ne-crankshaft ukuqinisekisa ukuthi indawo yokuxhumana nejenali ingaphezu kuka-75%. Amaphuzu okuxhumana kufanele ahlakazeke futhi ahambisane (ngokuhlola ukuthwala). Ukuqina kufanele kube ngokufanele. Ngemuva kokuqinisa ama-bolts ngokusho kwe-torque ecacisiwe, ama-bolts kufanele ajikeleze ngokukhululekile. Ukuqiniswa kakhulu kuzokwandisa ukuguga kwe-crankshaft kanye ne-bearing, futhi ukukhululeka kakhulu kuzodala ukulahlekelwa kwamafutha futhi kukhulise ukuguga.

I-axial clearance ye-crankshaft ilungiswa yi-thrust pad. Lapho kulungiswa, uma igebe le-axial likhulu kakhulu, i-thrust pad kufanele ishintshwe ukuze kuqinisekiswe ukuthi igebe lingaphakathi kobubanzi obuthile. Uma kungenjalo, i-crankshaft izohamba iye emuva naphambili lapho imoto yehla inyuka, okubangela ukuguga okungavamile kwe-bearing rod yokuxhuma kanye ne-crankshaft.


(2) Qinisekisa izinga nokuhlanzeka kwamafutha okugcoba

Sebenzisa uwoyela wokugcoba wezinga elifanele lekhwalithi. Amafutha enjini kadizili afanelekile kufanele akhethwe ngokuhambisana nomthwalo wenjini kadizili. Izithambisi zanoma yiliphi ibanga lekhwalithi zizoshintsha ngesikhathi sokusetshenziswa. Ngemva kwemayela elithile, ukusebenza kuzowohloka, kubangele izinkinga ezihlukahlukene enjinini kadizili. Ngesikhathi sokusebenza kwenjini kadizili, igesi engashi enengcindezi ephezulu, umswakama, i-asidi, isulfure nama-nitrogen oxides egumbini elivuthayo izongena ku-crankcase ngegebe eliphakathi kweringi yepiston nodonga lwesilinda, bese ixubana nempushana yensimbi egqokwayo. ngaphandle ngezingxenye ukwenza udaka. Uma inani lincane, lizomiswa emafutheni, futhi uma inani likhulu, lizophuma emafutheni, okuzovimbela isihlungi nezimbobo zikawoyela. Uma isihlungi sivinjiwe futhi uwoyela awukwazi ukudlula endaweni yokuhlunga, uzogqabula isici sokuhlunga noma uvule i-valve yokuphepha, futhi udlule ku-valve ye-bypass, ubuyisele ukungcola engxenyeni yokugcoba, ukwandisa ukungcoliswa kwamafutha kanye nokugqoka kwe-crankshaft okushubile. Ngakho-ke, amafutha kufanele ashintshwe njalo futhi i-crankcase kufanele ihlanzwe ukuze kugcinwe ingaphakathi lenjini ye-diesel ihlanzekile ukuze i-crankshaft isebenze kangcono.


(3) Lawula ngokuqinile izinga lokushisa elisebenzayo lenjini yedizili

Izinga lokushisa lihlobene eduze nokugcoba. Njengoba izinga lokushisa likhuphuka, i-viscosity yamafutha iba ngaphansi, futhi ifilimu yamafutha akulula ukwenza. Isizathu sokushisa okuphezulu ukuchithwa kokushisa okungalungile kwesistimu yokupholisa, ukugqwala kanye nokukala kwe-radiator yamanzi yizinkinga ezivamile. Ukugqwala nesikali kuzokhawulela ukugeleza kwesipholile ohlelweni lokupholisa. Isilinganiso eseqile sizonciphisa ukugeleza kwamanzi ajikelezayo, sinciphise umphumela wokukhipha ukushisa, futhi senze injini ye-diesel ishise ngokweqile; ngesikhathi esifanayo, ukuncishiswa kwesigaba somzila wamanzi kuzokwandisa ukucindezela kwamanzi, okubangela ukuvuza kwamanzi noma ukugcwaliswa kwamanzi Ukuchichima, amanzi okupholisa anganele, kulula ukuvula ibhodwe; futhi i-oxidation yoketshezi olupholile nayo izokwakha izinto ezine-asidi, ezizogqwala izingxenye zensimbi ze-radiator yamanzi futhi zidale umonakalo. Ngakho-ke, i-radiator yamanzi kufanele ihlanzwe njalo ukuze isuse ukugqwala kanye nesikali kuyo ukuze kuqinisekiswe ukusebenza okuvamile kwe-crankshaft. Izinga lokushisa elidlulele le-crankshaft yenjini ye-diesel lihlobene nesikhathi sokujova uphethiloli, ngakho-ke isikhathi sokujova uphethiloli kufanele silungiswe ngendlela efanele.
