EJBR02401Z Diesel Fuel Injector 33800-4X800 ye Hyundai Terracan Kia Carnival Kia Sedona

Kutevedzera iyo Yepamusoro-kumhanya Injector yeDiesel ICE(chikamu 4）

Kuwedzera kwekumhanya kweEHI kunovimbisa kupfupika nguva yekuendesa uye, nekudaro, zvinoreva jekiseni kudzvanywa uye kuyerera kwekutonga, kuderedzwa kweiyo shoma yakagadzikana kuburitsa. Pakutanga kuona, kuvhara tsono pasina kuwedzera kunogona kukurumidza nekusimbisa chitubu, asi mutsauko mukuru weiyi mhinduro isimba rekuvhara nguva dzose, kureva nekukasira kuvhara, kuzarura kuchaderedzwa zvakare. Nokudaro, chimiro chakaenzana chakaenzana hachikwanisi kuwanikwa nekuwedzera mechanical kuvhara simba retsono kana ichienzaniswa nekuwedzera; uye kana yakaderera kushanda nesimba, iyo EHI inova isina kugadzikana.

Zvinoenderana nemhedzisiro inozivikanwa yeongororo [6] yeEHI kukurumidza kumisa kunomisikidzwa nehupamhi hwemajekiseni kumanikidzwa, pamwe nekutsauka kweiyo chaiyo yekupa mamiriro kubva pane zvinodiwa. Zvisineyi, chirevo chiri pamusoro apa hachishandi maererano neEHI inoshanda nekumanikidza kunogara kuchikwira. Shanduko kune inogara ichimanikidza inobvumira kufunga akati wandei sarudzo dzekuwedzera injector inoshanda kumhanya:

1 kuwedzera kuomarara uye kukakavara kwechitubu chekudzoka, izvo zvinozvipa rimwe basa rekubhadhara sekushandiswa kune iri kukura tsono yekuvhura simba rinoshanda pamuromo wetsono;

2 kuderedza dhayamita yepistoni yekuwedzera pamwe nekuderera kunoenderana nehuwandu hwekamuri yekudzora;

3 kuderedza zvikamu zvemuchinjikwa zvebypass throttle uye chikamu chekuisa chisimbiso chevhavhavha yekudzora, pamwe nekuwedzera kuderera kwesimba rekudhonza uye kuwedzera kwekukurumidza kushanda kwevhavha ye solenoid.

Kuti uongorore mikana iri pamusoro yekuwedzera kukurumidza kwekushanda, imwe-dimention LMS Imagine.Lab AMESim [7,8] package yakasarudzwa. Bosch 0445110190 electrohydraulic injector ine solenoid control valve uye zviyero zvechigaro, yekubatanidza chikamu chetsono uye maburi (Table 1), inoenderana neatomizer yeYAZDA 33.1112010-03 serial injector yeKamAZ-7409 injini yakasarudzwa se. kugadzirwa kwekutanga kwemuenzaniso (Fig. 2). Zvinoenderana neyakafungidzirwa nzira, simulation yakaitwa uchishandisa mamodheru ane inoshanda inlet pressure ye100 MPa.
