IYunithi yeSibaso seDizili ethengisa ngokushushu 02112860 yezahlulo zenjini yeDizili yeDeutz

(1) umgaqo-nkqubo wokusebenza: I-electronic controlled monobloc pump injection system yahlulahlulwe ngokwala manqanaba alandelayo enkqubo yokusebenza: i-monobloc pump solenoid valve ifakwe kwindawo ephezulu yepompo ye-monobloc, i-valve ye-solenoid i-de-energized, i-valve yokubuyisela ivuliwe. , i-monobloc pump plunger nokuba sele iqalile ukupompa ioli, kodwa ayikwazi ukuseka uxinzelelo oluphezulu, kuphela xa i-valve ye-solenoid inamandla, umjelo wokubuyisela uvaliwe, uxinzelelo lweoli luya kwandiswa ngokukhawuleza; amafutha oxinzelelo oluphezulu ngombhobho we-oyile woxinzelelo oluphezulu kwi-injector ukwenza inaliti yamafutha. Xa i-valve ye-solenoid i-de-energized, i-oyile yokubuyisela ishaneli ivuliwe, kwaye uxinzelelo lweoyile luphuphuma ngokukhawuleza, kwaye i-injection iyayeka. Ivalve yeSolenoid enikwe amandla kangangexesha elithile imisela ubungakanani bobonelelo lweoyile yebhayisikile.
(2) inkqubo yokutshaja: i-valve ye-solenoid ayinamandla, xa i-plunger ihla, uxinzelelo lwangaphakathi lwenkqubo yokutofa luya kuba ngaphantsi koxinzelelo lwenaliti yesekethe ye-oyile ephantsi, i-fuel ye-low-pressure system iya kungena. inkqubo yokutofa yoxinzelelo oluphezulu ngokungena kumkhono weplunger.
3 i-valve yokubuyisela i-valve, ephantsi kakhulu kunoxinzelelo lokuvula lwe-injector, ukwenzela ukuba i-fuel ibuyele kwi-tank ye-fuel ngokusebenzisa umjelo wokubuyisela.
(4) Inkqubo yokujova: Ngexesha lokunyuka kwe-plunger, ukuba iyunithi yokulawula i-electronic (ECU) ithumela umqondiso wokulawula i-pulse injecting ngexesha elithile, ukwenzela ukuba i-valve ye-solenoid inikwe amandla, emva koko umjelo wokubuyisela uvaliwe; kwaye i-plunger cavity yenziwe ibe ngumthamo ovaliweyo, ngokunyuka kwe-plunger, i-fuel kwivolumu evaliweyo ixinzelelwe, kwaye uxinzelelo lukhuphuka ngokukhawuleza, kunye noxinzelelo ekupheleni komlomo we-nozzle. i-injector iphakama ngokukhawuleza, kwaye uxinzelelo lokuvula i-injector (malunga ne-300 bar) luphezulu kunolo lwe-injector, ngoko uxinzelelo lwe-fuel luya kumiselwa ngoxinzelelo lokuvula i-valve yokubuyisela, ephantsi kakhulu kunoxinzelelo lokuvula i-injector. Xa uxinzelelo luphezulu kunoxinzelelo lokuvula lwe-injector (malunga ne-300 bar), i-injector ivula kwaye i-fuel ifakwe kwigumbi lokutshisa. Uxinzelelo oluphezulu lwenaliti lufikelela kwi-1800 bar.
(5) Inkqubo yokukhulula: Xa umqondiso wokulawula i-injection pulse iphelile, i-valve ye-solenoid ikhutshwe amandla, i-channel yokubuyisela iphinda ivulwe, i-fuel overflows, uxinzelelo kwi-plunger chamber kunye nakwi-nozzle yehla ngokukhawuleza, i-nozzle ivaliwe, kwaye inkqubo yokutofa iyaphela.
