Ukuhlaziywa kwe-Transient states kwama-injection enjini ye-CI kusetshenziswa izindlela zokubona(INGXENYE 4)

2 Indlela yocwaningo

2.1. Indawo yokuhlola Ucwaningo lwenziwa ebhentshini lokuhlola e-Institute of Combustion Engines and Transport of Poznan University of Technology. Leli bhentshi lokuhlola liqukethe (isikimu salo siboniswa emfanekisweni 1): • I-Constant Volume Chamber (CVC) yokulingisa izimo ze-in-cylinder (i-back-pressure) evamile yokujova enjinini evuthayo yangaphakathi; ububanzi bokucindezela komoya bugcinwe bufika ku-10 MPa; Ikamelo linokufinyelela okubonakalayo kanye nezibani ezimbili ze-halogen ezingu-500 W zokukhanyisa amaconsi kaphethiloli.

• Isilandeleli ukuze sikhiqize amasignali okulawula (5 V, TTL) ohlelo lomjovo kanye namasignali anika amandla i-diode; ukulungiswa kwalolu cingo kungu-±1 ns.

 • Isitendi sesitimela esivamile sokuhlinzekwa kwamafutha; iqukethe i-high pressure fuel futha i-Bosch CP 4.1, isistimu yokulawula ukuze kuzuzwe ukucindezela kukaphethiloli kujantshi kufika ku-200 MPa kanye nenye iyunithi yokulawula ukuguqula amasignali ukusuka ku-sequence ibe isignali kagesi efanele ukuze ama-injection aqale futhi aqedele inqubo yomjovo.

• Izinsimbi zamanje (i-Chauvin Arnoux E3N enokulungiswa kokulinganisa okungu-10 mV/A) kanye ne-passive high impedance oscilloscope probe M007 by Pico Technology. Zombili zazisetshenziselwa ukukala amasignali kagesi ngaphambi komjovo.

 • Isistimu yokutholwa equkethe izinto ezimbili eziyinhloko: eyokuqala i-AVL IndiModul yokurekhoda amasignali kagesi (akalwa ngama-clamp kanye ne-probe) kanye namasignali okulawula asuka ku-sequencer; ukulungiswa kwe-500 kHz kumasignali phakathi nalokhu kuhlolwa kukhethiwe; enye ingxenye ikhamera yejubane eliphezulu i-HSS5 kaLaVision enejubane lokuqopha elingu-250 kfps.

3.2. Izinto zokuhlola kanye nebanga lokulinganisa Ezivivinyweni ama-injection amabili kaloliwe ajwayelekile ezinhlobo ezahlukene akhethiwe. Owokuqala kwakuwumjovo we-piezoelectric ka-Bosch kanti omunye wawungowohlobo lwe-electromagnetic, futhi nguBosch (amapharamitha awo akhonjisiwe kuthebula 1).
