Transient states ongororo yeCI injini majekiseni nekushandisa nzira dzemaziso

Abstract.

Chinangwa chikuru chekutsvagisa chaive chekutsanangura kunonoka kwejekiseni chaiyo kutarisana nenguva ye
magetsi ekudzora chiratidzo chepiezoelectric uye electromagnetic dizeli mafuta majekiseni.Yechipiri
Chinangwa chebasa iri kwaive kuongororwa kwesimba reyakajairika jekiseni paramita pane izvi
delay.Kuongorora kwakanangana nekuitika kwezviratidzo zvakakodzera zvekudzora zvakanyorwa ne
kushandiswa kwekukurumidza-kusiyana kwekutora data system uye kuenzaniswa nedata rakanyorwa nepamusoro
kasi kamera.Iwo maedzo akaitwa munogara vhoriyamu chamber yemhando dzakasiyana dzejekiseni
inoshandiswa mumajini ekupisa ane jekiseni rakananga remafuta edhiziri.Miedzo yakaitwa pasi
mamiriro akasiyana-siyana: akasiyana mafuta ekumanikidza, mhepo yekudzokera shure-kumanikidza uye jekiseni nguva yenguva.
1. Nhanganyaya
High pressure jekiseni remafuta emvura anoonekwa neyakajairwa njanji system inoda kunyatsojeka mumafuta
huwandu hunounzwa mukamuri rinobvira nejekitari.Parizvino kune marudzi maviri makuru emajekiseni
inowanzoshandiswa kune ese ari maviri compression ignition uye spark ignition injini: electromagnetic uye
piezoelectric.Kunyangwe kushanda kwemafuta kudzvanywa mune peturu jekiseni masisitimu yakanyanya kuderera mukati
kuenzanisa nemafuta edhiziri masisitimu, asi nguva dzekuvhura jekiseni dzinenge dzakafanana kune ese marudzi e
kuvaka.Icho chokwadi chinoita kuti zvinodiwa zvifanane neCI uye SI majekiseni.Midziyo iyi inofanira kuva
inoratidzirwa nekugona kukurumidza kupindura kune kwakakodzera kudzora masaini kune ese ari maviri kuvhura nekuvhara kushanda.
Payri et al.[1] akaongorora pesvedzero yemagetsi uye piezoelectric tekinoroji pa
jekiseni process ye indirect-acting piezoelectric uye solenoid majekiseni.Muchikamu ichocho hydraulic
maitiro akagadzirirwa ese ari maviri magadzirirwo uye obva aenzaniswa neimwe neimwe.Mutsvakurudzo iyi
peturu mwero chiratidzo chakavakirwa paBosch nzira yakashandiswa.Migumisiro yakawanikwa yakaratidza kukurumidza actuation ye
piezo-injector akaenzanisa solenoid.Zvazvinoreva ndezvekuti kunonoka kwavo kwehydraulic idiki.The
misiyano yaiwedzera inversely proportional kune jekiseni pressure.Chechipiri chekucherechedza kubva
bvunzo iyoyo yaive yekumhanyisa kumhanya kwemafuta epiezo-injector zvichienzaniswa neimwe dhizaini yakafanana
gomba dhayamita.
Tsvakurudzo yakafanana yakaitwa naYu et al.[2], asi mune iyo nyaya mafuta akasarudzwa kuti aferefete aive
parafini nemafuta edhiziri.Zvichienderana chete nezviratidzo zvekudzora uye kusiyanisa kwemafuta ekuyerera mwero kubva kune injector
nozzle, kunonoka kwejekiseni pakatarisana nenguva yekuvhurwa kwemagetsi chiratidzo kwakawanikwa.Zvinokosha izvi
parameter yaigara yakazvimiririra yekumanikidza jekiseni (munyaya iyi 60 uye 100 MPa) uye kunonoka
nguva dzaive dzakatevedzana 0.45 ms yepiezo- uye 0.55 ms ye solenoid jekiseni.Uyezve, kukurumidza kuyerera
kubva mujekiseni nozzle kune yakaderera jekiseni kudzvinyirirwa akaonekwa.Izvozvo zvinopa zvikomborero zvakakura kune
kupisa injini kushanda senge nani atomization uye evaporation yemafuta.Vanyori vakadaro vakashandisa
