Common Rail Fuel Injector Control Valve Assembly F00VC01386 yeMajekiseni 0445110387 & 0445110388

Transient states ongororo yeCI injini majekiseni nekushandisa nzira dzemaziso(CHIKAMU 7)

Kune ese ari maviri majekiseni kunonoka kupindura kwehardware kunoonekwa sekusingaperi uye iri 0.012 ms yepiezo- uye 0.016 yesolenoid jekiseni. Sezvo chiratidzo chechiedza che diode chikaitika pafuremu imwechete mushure mekutanga kuyerwa kwega kwega, zvinogona kutaurwa kuti zviyero zvakatsiga uye zvinodzokororwa. Mufananidzo 5 unopa nguva pfupi yekupa simba kune ese ari maviri majekiseni, sezvanga zvatotaurwa mune yekutsvagisa nzira. Nguva ino inokwana 0.2 ms uye 0.3 ms yepiezo- uye solenoid injector, zvichiteerana.

Pachati yepiezo-injector, maitiro ekumhanyisa jekiseni nekumanikidza kwakanyanya mukamuri kwakaratidzwa. Chete yePinj = 60 MPa tsika iyi yakasiyana, asi inogona kupesvedzerwa nemamiriro ezvinhu. Iyo solenoid injector yakanga ichishanda nenzira inodzokororwa uye iyo yekumashure-kudzvanywa haina kuita mutsauko wakakosha munguva yekunonoka. Muchiitiko ichocho pressure yejekiseni ndiyo yakaita kuti jekiseni rikurumidze, sezvayakanga yatoonekwa yepiezo-injector. Chakakodzera kutaurwa ichokwadi, kuti mhedzisiro ye solenoid injector kubva kuPinj pamusoro pe60 MPa kazhinji inosiyana ne ± 1 furemu chete, saka maererano nekuyera kwechiyero ivo vanofanirwa kubatwa sepasina mutsauko. Piezo-injector pakumanikidzwa kwejekiseni yakaderera yakawana kunonoka kwakaderera pane electro-injector, asi nekuwedzera kwekumanikidza kwakadzoserwa kumashure. Zvinofanira kucherechedzwa kuti piezo-injector dhizaini yekare: jekiseni remagetsi rakatsiva piezo-injector mumagadzirirwo emugadziri.

Mhedzisiro yekunonoka kwejekiseni kwenguva yepakati uye yakareba jekiseni inoratidzwa mumufananidzo 6 uye mufananidzo 7, zvichiteerana. Oparesheni yepiezo-injector inogona kuongororwa seyakangoitika. Pahwaro hwemhedzisiro kuenzanisa zvinogona kutaurwa, kuti mhepo yekumanikidza (kumashure-kudzvanywa) ine yakanyanya kukosha pesvedzero pakunonoka uye pesvedzero yekumanikidza kwemafuta ishoma. Mhedzisiro dzakada kufanana dzakawanikwa kune solenoid jekiseni, asi muchiitiko ichi pesvedzero huru pakunonoka kwejekiseni yaive nemafuta emafuta uye pesvedzero yemhepo yakange isina basa.
