intliziyo injini diesel yeyona pump elekhtrons, deliverying amafutha ukugcina isingqisho okanye ixesha eyenza ngempumelelo ukusebenza kwe engine.At ngexesha elinye, oko ukulawula ubungakanani amafutha sifumane required.While igunya injini ipetroli , umsebenzi impompo inaliti ye-ukho ukunyathela umcephe wokunyusa kunye system.So ucinezelo xa kukho probem kwi impompo ipetroli, kuyimfuneko ukuhlola ucinezelo, amafutha, kunye spark.Because akukho nkqubo ucinezelo kwi diesel engine.Comparing ku injini ipetroli, i-diesel, has inzuzo yoko ngqo zepetroli ngcono injection.Today China Balin Parts yeziTyalo, omnye umenzi jikelele iinxalenye zoololiwe eqhelekileyo i & iindawo isitofu idizili, uya kukubonisa indlela umsebenzi pump inaliti. Esemgceni-Inaliti (Jerk) neeMpompo Xa 1890s le iimpompo kuqala ukusebenzisa plungers ukunyanzela amafutha enemitha kwigumbi yokutsha baba developed.Later ngo-1927, impompo esisemgceni ubunzima-wavelisa kweleli-elawulwa nayo yaziswa BOSCH.The iimpompo, maxa wambi ebizwa jerk iimpompo, ikhangeleka ngathi Bosch P7100 (P-pump) nge-'94 ukuya '98 Dodge Ram 5.9L Cummins engines.Meanwhile ke ezakhiwe iiyunithi empompa impompo ezahlukeneyo ezinxulumene elayinini, omnye cylinder.They nganye ezivulwa yi cam, nto leyo mechanics eqhagamshelwe engine.Although abekho ukuya Ukuntsonkotha kwenkqubo ezilawulwa ngekhompyutha, le iimpompo usenalo umsebenzi ziyahluka timing.Inline isitofu iimpompo khangela ngathi esemgceni mini engines.It wanikela 3,000-5,000 psi xi inaliti ngenxa yokuqala mini iimpompo inaliti esemgceni gama 18.000 psi xi kuba asinini yakutshanje, Bosch P7100 leyo sikwazi ukufumana ngo-'94 ukuya '981/2 Cummins iinjini. Umthengisi (bokushicilela) Inaliti neeMpompo Kukho omnye kuphela impompo amafutha-yolinganiso kwi isitofu umhambisi pump.Similar ukuya ngomzi ukusebenza umgaqo kwi injini ipetroli, i-hydraulic elidityaniswe namazibuko ezahlukeneyo phezu kwentloko umhambisi ngokusebenzisa kukujikeleza rotor.This inaliti rotary kwimpompo esinokusibambisa ukuba zonke ngokutofwa amafutha ngqo lowo wenze package.Comparing ezincinane jikelele ukuya iimpompo esisemgceni, omnye iingenelo yayo kukuba iye ngaphantsi ezihambayo parts.Let masithabathe iimpompo mechanical rotary (Stanadyne DB2 kunye Bosch USEBENZE ) uxinzelelo example.The 6.700 psi lukhutshwe Stanadyne DB2 kunye 17,000 psi yi Bosch USEBENZE. Omnye umzekelo impompo electronic rotary ezifana Bosch VP44.It onokubangela 23,000 pressure.Even PSI ngokuzithelekisa ukuya iimpompo olutsha-kaloliwe CP3, sasingakwazi ke ndithi ke pump.Because bakrelekrele oko kuphela ukwenza uxinzelelo, kodwa ukulawula ixesha nobungakanani kwamafutha zisiwe enjinini. Common-Rail Inaliti Nge-elekhtrons eqhelekileyo-kaloliwe, impompo musa ukuba ilungelo kakhulu ukuba isigqibo xa amafutha ngayo pressurizes inqamla kunikelwa kwaye oko quantity.For Ngokomzekelo, impompo CP3 ifumana amafutha ukusuka amafutha tank.Then isebenzisa ziqu uyilo -piston ukwandisa uxinzelelo immensely.After koko, lo kaloliwe eqhelekileyo, sigcine i accumulator ngenxa injectors, le enoxinzelelo kakhulu injectors fuel.The kuthatha ngaphaya apho. Unit Injectors Iinjineli diesel okuqala kusoloko ukufumana iingxaki evela imigca ukudibanisa impompo inaliti ukuya injector.So amafutha ngo-1905, uCarl FRIENDS ndalahla kubo combing impompo inaliti kunye injector. Icandelo injector yinto compact uyilo isitofu amafutha apho ibhola pump kudala uxinzelelo oluphezulu ngumsebenzi wonyanxelo ngomatshini isicelo yi-injini. Ibhola kunye injector umxube zibe iqela elinye ezinomsebenzi kukuqhuba isitshizi kukudla kwigumbi yokutsha. Sikwazi ukufumana iyunithi injector isicelo ngokuqhelekileyo ukuba Volkswagens kunye iinjini diesel enkulu.
