I-Diesel Injector Fuel Injector A2c59515264 Siemens ye-Ford Ranger 3.0L Engine

Ucwaningo Lokulingisa Kumthelela Wokujova Okungalingani Kwezibaseli Zembobo Ngayinye Yomjovo Wenjini Kadizili Enqubweni Yomlilo(INGXENYE 3)

2 Imodeli yomlilo

Imodeli yejiyomethri yegumbi elivuthayo ku-TDC (isikhungo esiphezulu esifile) idwetshwa isofthiwe ye-ProE, njengoba kukhonjisiwe kuMfanekiso 1, futhi igcinwa njengefayela lefomethi ye-STEP. Imodeli yejiyomethri ingeniswa kusofthiwe ye-hyper mesh yokuhlukaniswa kwe-mesh futhi igcinwe njengefayela le-mesh ngesimo se-NAS. Ifayela le-mesh lingeniswa kusofthiwe ye-AVL FIRE ukuze ihlolwe nge-mesh, icwengisiswe, ukulungiselelwa kwe-mesh eguqukayo, ukukhethwa kwamamodeli amancane kanye nokusetha ipharamitha [6].

I-injector enezimbobo ezi-4 eyamukelwa injini ye-dizili ye-F186 inezimbobo ezi-4 ezisatshalaliswa ngokulinganayo, kodwa isiqondiso somjovo asihambisani ne-engeli yesigaba sesilinda. Isikhungo somgodi we-ω combustion chamber sine-offset engu-3 mm ukusuka phakathi nendawo ye-piston, futhi ukunyakaza komoya ku-cylinder kunomthelela ohlukile ezifutheni zikaphethiloli zembobo ngayinye, ngakho-ke yonke imodeli yegumbi lomlilo iyamukelwa. Imeshi ibethelwe endaweni eseduze nembobo kanye nomngcele, futhi imodeli yemeshi ku-TDC ikhonjisiwe kuMfanekiso 2. Kunamaseli anezikhala angu-140448 kanye nama-343488 e-TDC kanye ne-BDC (isikhungo esiphansi esifile) ngokulandelana.

Imingcele yenjini ye-diesel ikhonjiswe kuThebula 1. Isikhundla kanye nezilungiselelo zezinkomba zomjovo zimi kanje: X-coordinate (0.003 m), Y-coordinate (-0.003 m), Z-coordinate (0 m), X -isiqondiso (0.007), i-Y-direction (0.0397), i-Z-direction (0). Ukuhlelwa kwendawo yembobo ngayinye kukhonjisiwe kuThebula 2. Izinga lomjovo ofanayo kanye nezinga lomjovo elingalingani lembobo ngayinye lenziwa njengelungiselelo lomjovo, futhi izinga lomjovo liboniswa kuMfanekiso 3. Imodeli yokuthutha yengxenye evamile yamafutha edizili esetshenziselwa ukubala kwe-chemical reaction kinetics, futhi imodeli yokubala ehilelekile iboniswa kuThebula 3 [7, 8].
