Ngokuqhelekileyo, i-injini ine-phenomenon yokusetyenziswa kweoli, kwaye ukusetyenziswa kweoli ye-injini eyahlukeneyo ngexesha elithile akufani, kodwa nje ukuba ingagqithisi ixabiso lomda, yinto eqhelekileyo.
Ioyile ebizwa ngokuba "yitshisa" ithetha ukuba ioli ingena kwigumbi lokutshisa i-injini kwaye ithatha inxaxheba ekutshiseni kunye nomxube, okubangela ukuba kwenzeke ukusetyenziswa kweoli ngokugqithiseleyo. Ngoko kutheni injini itshisa ioli? Siyintoni isizathu sokusetyenziswa kweoli ephezulu?
Ukuvuza kweoli yangaphandle
Zininzi izinto ezibangela ukuvuza kwe-oyile, kuquka: imigca yeoli, imijelo ye-oyile, iigasthi ze-oyile epanini, iigaskithi zesivalo sevalvu, iigasthi zempompo yeoli, iigasket zempompo zamafutha, izitywini zekhava yekhonkco lexesha kunye nezitywino zecamshaft. Ezi zinto zingasentla ezinokuvuza ziyakwazi ukunyanzeliswa, kuba nokuba ukuvuza okuncinci kunokukhokelela kwixabiso elikhulu lokusetyenziswa kweoli. Indlela yokufumanisa ukuvuza kukubeka ilaphu elinombala okhanyayo ezantsi enjini kwaye ulijonge emva kokuqalisa injini.
Ukungaphumeleli kwetywina langaphambili nangasemva kweoli
Umphambili owonakeleyo kunye nomva ophambili ophethe izitywina zeoyile ngokuqinisekileyo ziya kukhokelela ekuvuzeni kweoyile. Le meko inokubonwa kuphela xa injini isebenza phantsi komthwalo. Olona tywino luphambili lweoyile kufuneka lutshintshwe emva kokugqoka, kuba njengokuvuza kweoyile, kuya kubangela ukuvuza okuphezulu.
Ukunxiba okuphambili okanye ukungaphumeleli
Iibheringi eziphambili ezigugileyo okanye ezingalunganga zinokusasaza i-oyile eninzi kwaye iphoswe kwiindonga ze-cylinder. Njengoko ukuthwala ukuguga kuyanda, ioli eninzi iphoswa phezulu. Ngokomzekelo, ukuba i-bearing design clearance ye-0.04 mm inika i-lubrication eqhelekileyo kunye nokupholisa, inani leoli eliphonswayo liqhelekileyo ukuba i-bearing clearance inokugcinwa. Xa i-gap inyuswa ukuya kwi-0.08 mm, inani leoli eliphoswe ngaphandle liya kuba ngamaxesha angama-5 inani eliqhelekileyo. Ukuba ukukhutshwa kunyuswe kwi-0.16mm, inani leoli eliphonsiweyo liya kuba ngamaxesha angama-25 inani eliqhelekileyo. Ukuba eyona nto iphambili iphosa ioyile eninzi, ioyile eyongezelelekileyo iya kutshiza kwisilinda, ithintele ipiston kunye namakhonkco episton ekulawuleni ngokufanelekileyo ioyile.
Ukuthwala intonga yokudibanisa egugileyo okanye eyonakeleyo
Umphumo wokudibanisa intonga ephethe imvume kwioli ifana neyona nto iphambili. Ukongezelela, ioli iphonswa ngokuthe ngqo kwiindonga ze-cylinder. Iibheringi zokudibanisa ezigugileyo okanye ezonakeleyo zibangela ukuba ioli eninzi iphoswe kwiindonga ze-cylinder, kwaye i-oyile engaphezulu ingangena kwigumbi lokutsha kwaye itshiswe. Qaphela: Ukungonelanga kokukhutshwa kwemvume akuyi kubangela ukunxiba ngokwayo, kodwa kunye nokunxiba kwipiston, amakhonkco episton kunye neendonga zesilinda.
