Magetsi Anodzora Diesel Genset VS EFI Diesel Genset

Ndeupi musiyano uripo pakati pemagetsi anodzorwa nedhiziri generator set neEFI dhiziri jenareta?

Panyaya yekukurumidza kudzora maitiro e dhiziri genset , EFI injini uye yemagetsi regulator ndeye chikamu chemagetsi kumhanya mutemo.Iwo akasiyana nemakanika kukurumidza kudzora kudzora maitiro, ayo anogona kuenzaniswa kubva kune anotevera maficha:

Chekutanga, mafuta jekiseni pressure.

Iyo yemagetsi regulator inopinza zvakananga dhiziri mucylinder kuburikidza neyakajairwa high-pressure pombi, uye jekiseni rayo rinodzvanywa nevhavha yekumanikidza pane jekiseni.Mushure mokunge mafuta emafuta ari mupombi yemafuta epamusoro asvika pamutengo wakaiswa wevhavha yevhavha, inomhanyira zvakananga kuvhura valve uye inoipinza muhumburumbira.Inokonzerwa nekugadzirwa kwemagetsi, kudzvinyirirwa kwevhavha yevhavha haigoni kuva yakakura zvikuru.

Injini yeEFI inotanga kuburitsa oiri-yakanyanya-kudzvanywa mukamuri yekudzvanya yemafuta ejekitori yemafuta nepombi yemafuta ekudzvanya.Iyo jekiseni yemafuta yeinjector yemafuta inodzorwa neiyo solenoid valve.Kana jekiseni remafuta richidikanwa, iyo yemagetsi control system inodzora solenoid valve kuvhura uye kubaya iyo yakanyanya-kudzvanywa mafuta mucylinder.Kudzvinyirirwa kwemafuta e-high-pressure hakugadziriswi nevhavha yevhavha uye inogona kuwedzerwa zvikuru.Iyo dhiziri jekiseni rinowedzera kubva pa100MPa kusvika 180MPa.Kudzvanya kwakadai kwejekiseni kwakakwira kunogona kuvandudza zvakanyanya kunaka kwekusanganiswa kwedhiziri nemhepo, kupfupisa nguva yekudzima, kuita kuti kupisa kuve nekukurumidza uye nekunyatso dzika, uye kudzora tembiricha yekupisa, kuitira kuderedza kubuda kwemhepo.

Chechipiri, yakazvimirira jekiseni pressure control.

Iyo jekiseni yekumanikidza yeoiri yekupa sisitimu yeakakwira-kudzvanya mafuta pombi yemagetsi inodzora injini ine hukama nekumhanya uye mutoro weinjini yedhiziri, iyo isingafadzi hupfumi hwemafuta uye kubuda pasi pemamiriro ekumhanya kwakaderera uye chikamu chikamu. .

Iyo mafuta ekupa system yeEFI injini ine kugona kudzora jekiseni kudzvanywa yakazvimirira nekumhanya uye mutoro.Inogona kusarudza iyo yakakodzera jekiseni kudzvanywa kuti ivandudze nguva yejekiseni uye kunonoka kunonoka nguva, uye kuita kuti kupera simba kweinjini yedhiziri kuve kwakaderera uye kune hupfumi pasi pemamiriro akasiyana ekushanda.

Chechitatu, yakazvimirira mafuta jekiseni nguva kudzora.

Iyo yepamusoro-yekumanikidza pombi yemagetsi regulator inofambiswa necamshaft yejini, uye nguva yayo yejekiseni zvakananga zvinoenderana nekona yekutenderera kwecamshaft.Mushure mekunge muchina wagadziriswa, nguva yayo yejekiseni yakagadziriswa.

Nguva yejekiseni yemuchina weEFI inogadziriswa zvachose nevhavhavha ye solenoid inodzorwa nemagetsi control system.Iko kugona kwejekiseni yekudzora nguva yakazvimirira yekutenderera kwemuchina ndiyo chiyero chakakosha kuwana chiyero chakanaka pakati pekushandisa mafuta uye kuburitsa.

Chechina, kukurumidza kucheka-kubvisa mafuta.

Mafuta anofanira kubviswa nokukurumidza pakupera kwejekiseni.Kana mafuta asingakwanisi kubviswa nokukurumidza, dhiziri inoiswa pasi pekumanikidzwa kwakadzika inobudisa utsi hutema nekuda kwekusakwana kwekupisa uye kuwedzera HC emission.

Iyo yakakwira-yekumhanya yemagetsi pa-off valve inoshandiswa mune jekiseni reEFI dhiziri iri nyore kuona nekukurumidza kudzima mafuta, asi yakanyanya-kudzvanywa mafuta pombi yemagetsi regulator haigone kuita izvi.

Chechishanu, iyo nzira yekushandisa yekumhanyisa kudzora.

The magetsi regulated dhiziri jenareta set ndiye gavhuna anodyisa kumashure chiratidzo chekumhanya chemuchina kuburikidza nekumhanya sensor.Gavhuna anoshandura mutsauko kuita chiratidzo chekumhanya nekuenzanisa iyo preset yekumhanyisa kukosha uye inotyaira actuator kudzora mafuta ekupa rack kana inotsvedza sleeve kuti ione kumhanya mutemo.Chiratidzo chekupa mafuta chinongoenderana nechiratidzo chekumhanya, uye kugadziridzwa kwemafuta kunowanikwa nemuchina wekuita kweiyo actuator.

Muchina weEFI unoshandisa masensa akadai sekumhanya, nguva yejekiseni, tembiricha yemhepo, kupinza mhepo, tembiricha yemafuta uye tembiricha yemvura inotonhorera kuisa maparamendi akaonekwa munguva chaiyo mukombuta (ECU) panguva imwe chete, enzanisa neyakachengetwa. isa parameter tsika kana parameter mepu (mepu), uye tumira mirairo kune actuator (solenoid vharafu) maererano neyakanaka kukosha kana kuverengerwa kukosha kwechinangwa mushure mekugadzirisa uye kuverenga.
