I-Diesel Injector Fuel Injector 0445120146 Bosch ye-Daewoo DV11 Euro 4 Doosan DV11 Euro 4 bh 120, Bx 212, Fx 116, Fx 117, Fx 120

Umthelela we-Double Injector on Combustion Process ku-396 Series Diesel Engine (ingxenye 3)

Imodeli yomlilo

Amapharamitha wesici senjini yedizili engu-396 enegumbi lokushiswa kwesitsha se-convex flat-top ikhonjisiwe kuThebula 1. Imodeli yejiyomethri idwetshwa isofthiwe ye-ProE, ukuhlukaniswa kwe-mesh kuqedelwa isofthiwe ye-Hypermesh, bese i-mesh ithuthukiswa futhi ibethelwe ngu- I-AVL FIRE. I-dynamic mesh isethelwe ukubala kanye nokuhlaziywa kwangemuva kokucubungula. Njengoba ukunyakaza kokugeleza komoya kusilinda ku-asymmetrical futhi kunomthelela ekusabalaliseni kwendawo kwesifutho sikaphethiloli nasenqubweni yokuvutha, imodeli isungulelwa yonke indawo yokuvutha. Kunamaseli anezikhala angu-56050 nangu-158900 e-TDC (isikhungo esiphezulu esifile) kanye ne-BDC (isikhungo esiphansi esifile) ngokulandelana, futhi imodeli yegumbi elivuthayo ku-TDC ikhonjisiwe kuMfanekiso 1.9.

Imingcele eyinhloko yama-injector emigodi engu-5 nezingu-8 kanye ne-double-injector enezimbobo ezi-4 ikhonjisiwe kuThebula lesi-2, futhi ama-injection anezimbobo zomjovo ezihlukene anenani elifanayo eliphelele lendawo yesigaba esiphambanayo esisebenzayo. Ukusatshalaliswa kwezinhlayiya zesifutho kusilinda ngemva kokujova uphethiloli ongu-5°CA kuboniswa kuMfanekiso 2. Isilinganiso samanje se-eddy kusilinda sibekwe ku-2.9, ukunyakaza komoya kusilinda asymmetric ngenxa yokuma kwe-valve yokungena, kanye nophethiloli. isifutho siphinde sibe nomthelela ekuhambeni kokugeleza komoya ngendlela efanele.10.

Isibalo se-chemical reaction dynamics senziwa ngemodeli yokuthutha yengxenye yedizili evamile yoMLILO, futhi ukukhethwa kwemodeli yokubala okuyinhloko kuboniswa kuThebula 3. Kumodeli yokuhlukana kwesifutho se-KHRT, inani le-coefficient C2 libekwe ku-12.

3. Imiphumela yokulingisa nokuhlaziya Umfanekiso 3, Umfanekiso 4 kanye noFigure 5 ngokulandelanayo ubonisa ukuqhathanisa nokuhlaziywa kwengcindezi kusilinda, izinga lokukhululwa kokushisa, izinga lokushisa elimaphakathi kusilinda, ukukhululwa kokushisa okunqwabelene kanye NO-CHA ingxenye enkulu uma i-5-hole kanye ne-8-hole injection. kanye ne-4-hole dual-injector iyamukelwa.
