Electronic mafuta injector inozivikanwawo seEUI, inoshanda sei?Nheyo yaro yekushanda inongova kuti chiratidzo chemagetsi chakabudiswa neECM chinotumirwa kune solenoid valve, iyo inodzora kuvhura uye kuvhara kwevhavha yetsono, nokudaro kuendesa imwe huwandu hwemafuta mukati meinjector.Huwandu uye nguva yejekiseni inodzorwa chaizvo neECM algorithm uye MAP.Huwandu hwejekiseni remafuta hunotarwa nenguva yejekiseni uye nekumhanyisa kweinjector plunger, uye yakaenzana kune mumwe nemumwe.Iyo nguva iyo solenoid valve inoshandiswa ndiko kutanga kwejekiseni remafuta, uye kurasikirwa kwesimba ndiko kupera kwejekiseni remafuta.Heano matanho mana chaiwo ekushanda ejekiseni.
Kusveta sitiroko
Iyo chiteshi chemafuta chakabatana nejini cylinder musoro kuendesa mafuta kuburikidza necylinder musoro kune ega majekiseni, saka dhizaini yemutsetse wemafuta inofanirwa kuve nechokwadi chekuti tembiricha yemafuta inowirirana pakati pemajekiseni.Mushure mokunge mafuta apinda mujekiseni, mafuta anochengeterwa uye anotonhorera muimba yemukati, asi mvura nemhepo mumafuta zviri kuitwa.Munguva iyi sitiroko, jekiseni plunger inosimuka uye mafuta anodira mujekiseni, achizadza mhango yejekiseni.
Jekiseni sitiroko
Kana jekiseni plunger richitanga kudzika pasi, mafuta ari pasi pepingi anomanikidzwa kubuda mujekiseni odzokera kudunhu remafuta.Kana iyo ECM isingaratidzi solenoid valve, zvino yese ichadzokera kudunhu remafuta.Kana iyo ECM ichipa chiratidzo kune solenoid valve, iyo valve yetsono inodzorwa neiyo solenoid valve yakavharwa, uye mafuta haagone kudzoka kudunhu remafuta, uye kumanikidza kunoramba kuchiwedzera sezvo plunger inoramba ichidzika, ichiva yakakwirira. -kumanikidza mafuta, kumanikidza vharafu yemuromo kuvhura uye kutanga kupfapfaidza.Iyo yakanyanya jekiseni pressure haisi pakutanga kwejekiseni, asi pedyo nekunopera kwejekiseni.
Kusara sitiroko
Iyo jekiseni inoenderera mberi kusvikira iyo solenoid valve isisina simba, panguva iyo solenoid tsono valve inotanga, mafuta e-high-pressure anosunungurwa, anopinda mumhepo yemafuta, uye valve yejojo yakavharwa.
