Transient states ongororo yeCI injini majekiseni nekushandisa nzira dzemaziso(CHIKAMU 4)

2 Nzira yekutsvakurudza

2.1. Test stand Tsvagurudzo yakaitwa pabhenji rekuyedza muInstitute of Combustion Engines uye Transport yePoznan University of Technology. Iri bhenji rekuedza rinosanganisira (chirongwa chayo chinoratidzwa mumufananidzo 1): • A Constant Volume Chamber (CVC) yekufananidza mu-cylinder mamiriro (kumashure-kudzvinyirira) kunowanzoita jekiseni mujini inopisa mukati; air pressure range yakachengetwa kusvika ku10 MPa; kamuri ine optical access uye maviri 500 W halogen marambi ekuvhenekera madonhwe emafuta.

• Sequencer kugadzira zviratidzo zvekutonga (5 V, TTL) yejekiseni system uye zviratidzo zvinosimbisa diode; kugadziriswa kwemudziyo uyu ± 1 ns.

 • Nzvimbo yenjanji yakajairika yekugovera mafuta; ine high pressure fuel pombi Bosch CP 4.1, a control system yekuwana mafuta ekumanikidza munjanji kusvika ku200 MPa uye imwe control unit yekushandura masaini kubva kune sequencer kuita chiratidzo chemagetsi chakakodzera kuti majekiseni atange uye apedze jekiseni.

• Zvibatiso zviripo (Chauvin Arnoux E3N ine measing resolution ye10 mV/A) uye passive high impedance oscilloscope probe M007 by Pico Technology. Zvose zvakashandiswa kuyera zviratidzo zvemagetsi pamberi pejekiseni.

 • Nzira yekutora iyo inosanganisira zvinhu zviviri zvikuru: yekutanga ndeye AVL IndiModul kunyora zviratidzo zvemagetsi (kuyerwa nemagetsi uye probe) uye kutonga zviratidzo kubva kune sequencer; sarudzo ye500 kHz yezviratidzo panguva iyi bvunzo yakasarudzwa; chimwe chinhu ndeyekumhanya kwekamera HSS5 neLaVision nekurekodha kumhanya kwe250 kfps.

3.2. Edzai zvinhu uye chiyero chekuyera Pamiyedzo maviri akajairika-njanji majekiseni emhando dzakasiyana akasarudzwa. Yekutanga yaive piezoelectric jekiseni naBosch uye imwe yacho yaive yemhando yemagetsi, zvakare naBosch (maparamita avo anoratidzwa mutafura 1).
