ULumkelo lweSixhobo sokuTofa i-injini yeDizili yaseLwandle (5-9)
2021-07-21
Kwinqaku lokugqibela, sikhankanye amanqaku angama-1-4 malunga nesixhobo sokutofa kwe-injini ye-diesel yaselwandle, kwaye amanqaku angama-5-9 alandelayo nawo abaluleke kakhulu.

5) Emva kokupaka ixesha elide okanye emva kokuba isixhobo sokujova i-fuel sidityanisiwe, sihlolwe kwaye siphinde sifakwe, qwalasela izixhobo ze-fuel injection kunye ne-fuel system bleed. Makungabikho kuvuza kwamafutha naphina kwisixhobo sokutofa ngamafutha.
I-6) Nika ingqalelo kwimeko ye-pulsation yombhobho weoli ophezulu ngexesha lokusebenza. I-pulsation iyanda ngokukhawuleza kwaye ipompo ye-oyile ephezulu yenza izandi ezingaqhelekanga, ezibangelwa ubukhulu becala ngokufakwa kwe-nozzle okanye i-valve yenaliti kwindawo evaliweyo; ukuba umbhobho we-oyile woxinzelelo oluphezulu awunayo i-pulsation okanye i-pulsation ibuthathaka, ibangelwa kakhulu yi-plunger okanye i-valve yenaliti. Indawo evulekileyo ibanjwe okanye i-injector spring yaphukile; ukuba i-pulsation frequency okanye ubunzulu buguquka rhoqo, iplunger ixingile.
I-7) Ukuba i-oyile ye-cylinder yokumisa iyadingeka ngexesha lokusebenza kwe-injini ye-diesel, i-oyile yepompo plunger kufuneka iphakanyiswe kusetyenziswa i-oil-high-pressure oil pump ekhethekileyo indlela yokumisa i-oyile. Musa ukuvala ivalve yokukhupha amafutha yempompo yamafutha oxinzelelo oluphezulu ukukhusela iplunger kunye neenxalenye ukuba zingavaleki ngenxa yokungabikho kokuthambisa.
8) Nika ingqalelo kwiimeko zokusebenza zenkqubo yokupholisa i-fuel injector ukuze uqinisekise ukupholisa okuthembekileyo kwe-coil injection ye-fuel kunye nokukhusela ukushisa. Jonga rhoqo inqanaba lolwelo lwetanki yokupholisa inaliti yamafutha. Ukuba inqanaba lolwelo liyenyuka, oko kuthetha ukuba kukho ukuvuza kweoli kwi-injector yamafutha.
9) Nika ingqalelo utshintsho kwinkqubo yokutshisa ngaphakathi kwetanki. Unokugweba iimeko zokusebenza zesixhobo se-injection ye-fuel ukusuka kwiinguqu ezingaqhelekanga kumbala wokukhupha umsi, ukushisa kweqondo lokushisa, umzobo wesalathisi, njl., kwaye ulungelelanise ngokufanelekileyo ukuba kuyimfuneko.
