Excavator Zvikamu Diesel Common Rail Diesel Fuel Injector 2488244 ye Scania DX350 DX350LC-5 Engine DC13 DC16

Mune yakaoma mashandiro sisitimu yeazvino mota injini, iyo jekiseni yemafuta pasina mubvunzo chinhu chakakosha zvakanyanya. Zvakafanana ne "fuel scheduler" chaiyo, ine chekuita nekuita kweinjini, hupfumi hwemafuta uye kubuda kwemhepo.

Iyo yakakosha kushanda musimboti wejekiseni ndeyekupinza mafuta mukamuri yekupisa injini nenzira yemafuta akapimwa nemaatomu. Kana iyo injini yekudzora unit (ECU) zvinoenderana nemasaini kubva kune akasiyana masensa, senge air flow sensors, crankshaft position sensors, nezvimwewo, kuona mamiriro ekushanda einjini uye kudiwa kwemutoro, inotumirwa kune injector. chiratidzo chemagetsi chinoenderana. Mushure mekunge jekiseni ragamuchira chiratidzo, iyo yemukati solenoid coil inokurumidza kusimba, ichigadzira magineti, kuitira kuti vharafu yetsono ikunde simba rechirimo nekusimudza, nokudaro kuvhura gomba rejekiseni. High-pressure mafuta ichava pasi pechiito chekusiyana kwekumanikidza, kupfapfaidzwa mukamuri rinopisa nemhute, uye mhepo mumusanganiswa wakazara, kuumbwa kwemusanganiswa unopisa, wakagadzirira kugadzirisa.

Iyo chaiyo kudzora yeinjector yekupfapfaidza nguva uye vhoriyamu ndiyo yakakosha tekinoroji. Pasi pemamiriro akasiyana ekushanda kweinjini, senge idling, kukwidziridza, kufamba nechikepe uye kushanda kwakakwira, kudiwa kwemafuta kunosiyana zvakanyanya. Iyo jekiseni inopindura pakarepo kumirairo yejini yekudzora unit uye inonyatso gadzirisa kutanga uye nguva yejekiseni kuti ive nechokwadi chekuti huwandu hwemafuta akaiswa mukamuri yekupisa hwakarurama. Munguva yekutonhora kwekutanga, injini inoda musanganiswa wakakura kuti ive nechokwadi chekutanga, uye jekiseni rinowedzera huwandu hwemafuta akaiswa; nepo panguva yekufambisa-kumhanya-mhanya, kuitira kuvandudza hupfumi hwemafuta, inoderedza huwandu hwemafuta anobaiwa kuita kuti musanganiswa uve mutete. Iyi chaiyo yekudzora kugona haingoiti yakagadzikana uye inobudirira kushanda kweinjini pasi pemamiriro akasiyana ekushanda, asi zvakare inoderedza zvakanyanya kushandiswa kwemafuta uye kubuda kwezvinhu zvinokuvadza mumhepo yekubuda.
