Inkqubo yokusebenza ye-injini ye-diesel eneneni iyafana naleyo ye-injini yepetroli, kwaye umjikelo ngamnye wokusebenza uphinda ufumane izibetho ezine zokuthatha, ukunyanzeliswa, ukusebenza kunye nokukhupha. Nangona kunjalo, ngenxa yokuba amafutha asetyenziswa kwiinjini yediziliidizili, i-viscosity yayo inkulu kunepetroli, akukho lula ukujika ibe ngumphunga, kwaye ubushushu bayo bokutsha obuzenzekelayo bungaphantsi kunepetroli, ngoko ke ukumila kunye nemowudi yokutshisa yomxube otshayo yahlukile kwiinjini zepetroli.
Xa i-Angle yokunikezelwa kwamafutha kwangaphambili ikhulu kakhulu, i-fuel ifakwe kwimeko yobushushu bomoya obuphantsi kwi-cylinder, imeko yokwakheka komxube imbi, ukuqokelelwa kwe-oyile phambi kokutsha kuninzi kakhulu, okubangela ukuba injini ye-diesel isebenze rhabaxa, ukungazinzi kwesantya sokungenzi nto kunye nobunzima bokuqala; Ngokuhamba kweyure, i-fuel iya kuveliswa emva kokutsha, ubushushu obukhulu kunye noxinzelelo lokutsha luya kuncipha, ukutsha akuphelelanga kwaye amandla aya kuncipha, kwaye ukukhupha kuya kukhupha umsi omnyama, kwaye injini yedizili iya kutshisa kakhulu, kubangele ukuncitshiswa kwamandla kunye noqoqosho. Elona liphezulu fuel advance Angle ayikho rhoqo, kwaye kufuneka kwandiswe kunye utshintsho umthwalo diesel (unikezelo fuel) kunye nesantya, oko kukuthi, kunye nokwanda kwesantya. Ngokucacileyo, i-Angle yokubonelelwa kwangaphambili kwe-oyile inkulu kancinci kune-Angle yenaliti ye-oyile. Ngenxa yokuba iAngle yokubonelela ngeoyile kulula ukuyijonga kwaye ifundeke, isetyenziswa ngakumbi kwiyunithi yemveliso kunye nesebe lokusebenzisa.
Ukuba i-engile phakathi komgca osembindini kunye nomgca othe nkqo wejenali ye-crankshaft yokudibanisa intonga inkulu kakhulu, oko kukuthi, i-oyile yokubonelela kwangaphambili i-Angle inkulu kakhulu, i-piston ikude kakhulu ne-TDC, ngeli xesha i-fuel ingena kwi-cylinder, iya kutshisa kwangaphambili, ivelise amandla, ukuze ipiston ingafiki kwi-TDC ekunciphiseni, ngoko umlinganiselo woxinzelelo kwi-cylinder uya kuncitshiswa, amandla e-injini nawo aya kuncipha, kwaye ubushushu buyanda. Kwaye kukho isandi esinkqonkqozayo ngaphakathi kwisilinda.
Uninziiinjini zedizilimisela eyona Angle yokutofa kwangaphambili phantsi kwemeko yesantya esilinganisiweyo kunye nomthwalo opheleleyo ngovavanyo. Xa impompo yokutofa ifakwe kwiinjini yedizili, iAngle yokutofa kwangaphambili ihlengahlengiswa ngokwale nto, kwaye ngokubanzi ayisayi kutshintsha ngexesha lenkqubo yokusebenza kwenjini yedizili. Ngokucacileyo, xa iinjini yediziliisebenza phantsi kwezinye iimeko, le Angle yokutofa kwangaphambili ayisiyiyo eyona ilungileyo. Ukuze kuphuculwe uqoqosho kunye nokusebenza kwamandla kweinjini yedizilingoluhlu lwesantya esikhulu, kuthenjwa ukuba inaliti engaphambili Angle yeinjini yediziliinokulungiswa ngokuzenzekelayo ngotshintsho lwesantya ukugcina ixabiso elithandeka ngakumbi. Ngoko ke, impompo yokutofa okuinjini yedizili, ingakumbi injini yedizili yokutofa ngokuthe ngqo, isoloko ixhotyiswe nge-centrifugal fuel supply advance Angle automatic regulator.
