(1) Xa ulungisa, qinisekisa umgangatho wendibano

Xa udibanisa i-crankshaft ye-injini ye-diesel, inyathelo ngalinye kufuneka lichanekile. Ngaphambi kokufaka i-crankshaft, coca i-crankshaft kwaye ucoce i-oyile ye-crankshaft kunye nomoya woxinzelelo oluphezulu. Ezinye ii-crankshafts zinemingxuma esecaleni kwaye zivaliwe ngezikrufu. Ukungcola okwahlukileyo kwioli ngenxa yamandla e-centrifugal kuya kuqokelela apha. Susa izikrufu kwaye uzicoce ngononophelo.

Xa udibanisa i-crankshaft, kuyimfuneko ukukhetha iibheringi ezikumgangatho ophezulu kwaye ube kwinqanaba elifanayo ne-crankshaft ukuqinisekisa ukuba indawo yoqhagamshelwano kunye nejenali ingaphezulu kwe-75%. Amanqaku oqhagamshelwano kufuneka ahlakazeke kwaye ahambelane (ngokuhlola ukuthwala). Ukuqina kufuneka kube ngokufanelekileyo. Emva kokuqinisa iibholithi ngokwetorque echaziweyo, iibhotshi kufuneka zijikeleze ngokukhululekileyo. Ukuqiniswa kakhulu kuya kwandisa ukunxiba kwe-crankshaft kunye nokuthwala, kwaye ukukhululeka kakhulu kuya kubangela ilahleko yeoli kunye nokunyusa ukunxiba.

I-axial clearance ye-crankshaft ihlengahlengiswa yi-thrust pad. Xa kulungiswa, ukuba i-axial gap inkulu kakhulu, i-thrust pad kufuneka itshintshwe ukuze kuqinisekiswe ukuba i-gap iphakathi koluhlu oluthile. Kungenjalo, i-crankshaft iya kuhamba emva naphambili xa isithuthi sisihla sinyuka, nto leyo ebangela ukuguga okungaqhelekanga kwebheringi yentonga yokudibanisa kunye ne-crankshaft.


(2) Qinisekisa umgangatho kunye nokucoceka kweoli yokuthambisa

Sebenzisa ioyile yokuthambisa yomgangatho ofanelekileyo. I-oyile ye-diesel efanelekileyo kufuneka ikhethwe ngokomthwalo we-injini ye-diesel. Izithambiso zalo naliphi na ibakala lomgangatho ziya kutshintsha ngexesha lokusetyenziswa. Emva komgama othile, ukusebenza kuya kuhla, kubangele iingxaki ezahlukeneyo kwi-injini yedizili. Ngexesha lokusebenza kwe-injini ye-diesel, igesi ephezulu yoxinzelelo engatshiyo, ukufuma, i-asidi, isulfure kunye ne-nitrogen oxides kwigumbi lokutsha iya kungena kwi-crankcase ngesithuba esiphakathi kweringi yepiston kunye nodonga lwesilinda, kwaye ixube kunye nomgubo wesinyithi onxitywayo. ngaphandle ngamalungu ukwenza udaka. Xa isixa sincinci, siya kumiswa kwioli, kwaye xa isixa sikhulu, siya kukhupha ioli, eya kuthintela isihluzo kunye nemingxuma yeoli. Ukuba isihluzo sivaliwe kwaye i-oyile ayinakudlula kwinto yokucoca, iya kugqabhuka into yokucoca okanye ivule ivalve yokhuseleko, kwaye idlule kwivalve yokudlula, ibuyise ubumdaka kwindawo yokuthambisa, inyusa ungcoliseko lwe-oyile kunye nokunxitywa kwe-crankshaft. Ngoko ke, i-oyile ifanele itshintshwe rhoqo kwaye i-crankcase kufuneka icocwe ukugcina ingaphakathi le-injini ye-diesel icocekile ukuze i-crankshaft isebenze ngcono.


(3) Lawula ngokungqongqo ubushushu obusebenzayo be-injini ye-diesel

Ubushushu bunxulumene ngokusondeleyo nokuthambisa. Njengoko iqondo lokushisa linyuka, i-viscosity yeoli iba ngaphantsi, kwaye ifilimu yeoli ayilula ukwenza. Isizathu sokushisa okuphezulu kukuchithwa kakubi kokushisa kwenkqubo yokupholisa, ukugqwala kunye nokunyuka kwe-radiator yamanzi ziingxaki eziqhelekileyo. Umhlwa kunye nesikali ziya kukuthintela ukuhamba kwesipholisi kwisixokelelwano sokupholisa. Umlinganiselo ogqithisileyo uya kunciphisa ukuhamba okujikelezayo kwamanzi, ukunciphisa umphumo wokutshatyalaliswa kobushushu, kwaye kubangela ukuba injini ye-diesel igqithise; ngelo xesha, ukuncitshiswa kwecandelo lomsele wamanzi kuya kwandisa uxinzelelo lwamanzi, kubangela ukuvuza kwamanzi okanye ukuzaliswa kwamanzi Ukuphuphuma, ukungonelanga kwamanzi okupholisa, kulula ukuvula ibhodwe; kunye ne-oxidation yolwelo olupholisayo luya kwenza izinto ezine-asidi, eziya kutshabalalisa iindawo zetsimbi ze-radiator yamanzi kwaye zibangele umonakalo. Ngoko ke, i-radiator yamanzi kufuneka ihlambuluke rhoqo ukuze isuse i-rust kunye nesikali kuyo ukuqinisekisa ukusebenza okuqhelekileyo kwe-crankshaft. Ubushushu obugqithisileyo be-crankshaft ye-injini ye-diesel bukwanxulumene nexesha lokutofa kwe-fuel, ngoko ke ixesha lokutofa kwe-fuel kufuneka lihlengahlengiswe ngokuchanekileyo.
