High Quality Common Rail Control Valve Set Gungano F00RJ01334 ye Diesel Injector 0445120047 0445120091 0445120093

Mavharuvhu eSolenoid kana piezoelectric anoita kuti zvikwanise kutonga zvakanaka zvemagetsi pamusoro penguva yemafuta-jekiseni uye huwandu, uye kudzvanywa kwepamusoro kunoitwa netekinoroji yenjanji inowanisa inopa mafuta ari nani atomisation. Kudzikisa ruzha rweinjini, injini yemagetsi inodzora unit inogona kupinza diki dhiziri nguva pfupi isati yaitwa chiitiko chikuru chejekiseni ("pilot" jekiseni), nokudaro ichideredza kuputika kwayo uye kudedera, pamwe nekugadzirisa jekiseni nguva uye huwandu hwekusiyana kwemhando yemafuta. , kutonhora kutanga, zvichingodaro. Mamwe masisitimu emafuta echitima epamusoro anoita majekiseni anosvika mashanu pasitiroko.

Injini dzenjanji dzakajairwa dzinoda ipfupi kwazvo kusvika isina kupisa-up nguva, zvinoenderana neambient tembiricha, uye inoburitsa yakaderera injini ruzha uye emissions kupfuura ekare masisitimu.

Injini dzedhiziri dzakagara dzichishandisa nzira dzakasiyana dzejekiseni remafuta. Mhando mbiri dzakajairika dzinosanganisira iyo unit-injection system uye distributor/inline-pombi masisitimu. Nepo aya masisitimu echikuru achipa huwandu hwemafuta hwakakwana uye jekiseni rekutonga nguva, anoganhurirwa nezvinhu zvakati wandei:

Iwo anotyairwa necam, uye jekiseni kudzvanywa kwakaenzana nekumhanya kweinjini. Izvi zvinowanzoreva kuti iyo yakanyanya jekiseni kumanikidza inogona chete kuwanikwa nekumhanya kweinjini yepamusoro uye iyo yakanyanya kuwanikwa jekiseni pressure inodzikira sezvo injini inomhanya inodzikira. Hukama uhwu ndehwechokwadi nemapombi ese, kunyangwe ayo anoshandiswa pane zvakajairika njanji masisitimu. Neyuniti kana dhizaini masisitimu, kudzvanywa kwejekiseni kunosungirirwa kune pakarepo kudzvanywa kwechiitiko chimwe chekupomba pasina accumulator, saka hukama hwacho hune mukurumbira uye hunonetsa.

Izvo zvishoma muhuwandu uye nguva yezviitiko zvejekiseni zvinogona kurairwa panguva yechiitiko chimwe chekupisa. Nepo zviitiko zvakawanda zvejekiseni zvichigoneka neaya ekare masisitimu, zvakanyanya kuoma uye zvinodhura kuita.

Kune yakajairwa dhizaini/inline system, kutanga kwejekiseni kunoitika panguva yakafanotemerwa dzvinyiriro (inowanzonzi pop pressure) uye inopera pakafanotemerwa dzvinyiriro. Hunhu uhwu hunobva kune "mbeveve" majekiseni ari muhumburumbira wemusoro unovhurika nekuvharika pakumanikidzwa kunotemerwa nechirimo preload inoiswa kune plunger mune jekiseni. Kana kudzvanywa kwejekiseni kwasvika padanho rakafanotarwa, plunger inosimudza uye jekiseni rinotanga.
