Inhliziyo udizili sika futha fuel injection, deliverying fuel ukuze silondoloze isigqi noma isikhathi lapho ukwenza egijima ngempumelelo ye engine.At esifanayo, futhi ukulawula ubukhulu fuel azuze required.While amandla injini uphethiloli , umsebenzi futha umjovo sika ku mpintsha kanye system.So ukuthungela uma kukhona probem e futha uphethiloli, kubalulekile ukuhlola kokucindezelwa, uphethiloli spark.Because akukho uhlelo ukuthungela ku engine.Comparing udizili ukuze injini uphethiloli, injini diesel has inzuzo yalokho ngqo uphethiloli kangcono injection.Today China Balin izingxenye Plant, nomakhi global ezivamile wesitimela izingxenye & udizili umjovo izingxenye, sizokubonisa indlela umsebenzi umjovo futha. Okusemgqeni-umjovo (Jerk) Pumps Ngo 1890s amaphampu kuqala ukusebenzisa plungers ukuphoqelela fuel alinganisiwe egumbini amandla omlilo babe developed.Later ngo-1927, mass-kukhiqizwa Helix-elawulwa uxhumekile kwi-inthanethi futha, kanti kuphinde kwethulwa by BOSCH.The iphampa, ngezinye izikhathi ebizwa ngokuthi Jerk amaphampu, libukeka Bosch P7100 (P-futha) ku '94 ukuze '98 Dodge Ram 5.9L Cummins engines.Meanwhile akha kusuka ahlukene futha plunger amayunithi exhunywe uxhumekile kwi-inthanethi, omunye cylinder.They ngayinye ocushiwe ngumuntu cam, okuyinto athutha exhunywe kwi-engine.Although akuzona yinkimbinkimbi uhlelo ngekhompyutha elawulwa, amaphampu kusadingeka umsebenzi ziyahlukahluka timing.Inline umjovo amaphampu ibukeke uxhumekile kwi-inthanethi mini engines.It zilethwe 3,000-5,000 psi umjovo kwengcindezi ngaphambi mini uxhumekile kwi-inthanethi umjovo amaphampu ngenkathi 18,000 psi yokucindezelwa komnikelo zakamuva, Bosch P7100 esasingenakuthemba ukuthola '94 ukuba '981/2 Cummins izinjini. Ukusabalalisa (rotary) Umjovo Pumps Yinye kuphela plunger fuel-metering ku pump.Similar distributor umjovo distributor isimiso abasebenza injini uphethiloli, i-wokubacindezela ehlangene izimbobo ezahlukene ekhanda distributor ngokusebenzisa ukuphotha rotor.This umjovo rotary futha inebuhle ukuthi zonke isibhamu uphethiloli ziyefana ezenza ezincane package.Comparing jikelele amaphampu uxhumekile kwi-inthanethi, yayo kwenye izinzuzo ukuthi unakho kancane ezihambayo parts.Let sithathe amaphampu rotary mechanical (Stanadyne DB2 kanye Bosch VE ) i-example.The ingcindezi 6.700 psi kuveza Stanadyne DB2 futhi 17,000 psi ngu Bosch VE. Esinye isibonelo isifutho electronic rotary like Bosch VP44.It ongaveza 23.000 psi pressure.Even ngokuqhathaniswa entsha ezivamile-wesitimela CP3 amaphampu, thina futhi ekwazi ukusho kuba pump.Because bayiziphukuphuku ke hhayi kuphela kungase kudale ingcindezi, kodwa futhi ukulawula isikhathi kanye nobungako uphethiloli zilethwe injini. Common-Rail Injection Nge ezivamile-wesitimela fuel injection, futha akudingeki kwesokudla kakhulu ukunquma lapho uphethiloli ke pressurizes Ufika zilethwe futhi ngasiphi quantity.For Ngokwesibonelo, futha CP3 uthola uphethiloli uphethiloli tank.Then lisebenzisa osabalalayo umklamo -piston ukwandisa ingcindezi immensely.After ukuthi, wesitimela ezivamile, ngokuyisisekelo i accumulator ngokuba injectors, uthole le Umfutho kakhulu fuel.The injectors zilawule kusuka lapho. Unit Injectors okuqala udizili onjiniyela njalo engamtholi izinkinga ikhiqizwa emigqeni yokuxhuma futha umjovo kuya injector.So uphethiloli ngo-1905, uCarl Weidman ngiyilahle sazo ngokuthinta ecwaninga futha umjovo kanye injector. Iyunithi injector iyi-compact fuel injection design lapho plunger futha kudala ingcindezi eliphezulu ngebutho mechanical Kusetshenziswe injini. I plunger futhi injector lenhlanganisela ku eyodwa abenza umsebenzi is sindise spray fuel egumbini amandla omlilo. Asikwazanga ukuthola iyunithi injector zisebenza ngokuvamile ukuze Volkswagens diesel izinjini ezinkulu.
