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

Isiphumo se-Double Injector kwiNkqubo yokuTsha kwi-396 Series ye-Diesel Engine (inxalenye yesi-3)

Imodeli yokutsha

Iimpawu zeempawu ze-396 ye-injini ye-diesel ene-flat-top convex igumbi lokutshisa i-convex iboniswe kwiThebhile 1. Imodeli yejometri izotywe yi-software ye-ProE, ulwahlulo lwe-mesh lugqitywe yi-software ye-Hypermesh, kwaye emva koko i-mesh iphuculwe kwaye i-encrypted. UMLILO we-AVL. Umnatha oguquguqukayo usetelwe ukubala kunye nohlalutyo lwasemva kokulungiswa. Njengoko intshukumo yokuhamba komoya kwisilinda i-asymmetrical kwaye inempembelelo kunikezelo lwendawo yesitshizi samafutha kwaye emva koko kwinkqubo yokutsha, imodeli isekwe kulo lonke igumbi lokutsha. Kukho iiseli ze-56050 kunye ne-158900 ze-mesh kwi-TDC (iziko eliphezulu elifile) kunye ne-BDC (indawo esezantsi efileyo) ngokulandelanayo, kunye nemodeli yegumbi elivuthayo kwi-TDC iboniswe kuMfanekiso 1.9.

Iiparameters eziphambili ze-5-hole kunye ne-8-hole injectors kunye ne-4-hole-double-injector iboniswe kwiThebhile 2, kwaye ii-injection ezinemingxuma ehlukeneyo ye-injection zineendawo ezifanayo ezisebenzayo ezinqamlezayo. Ukusasazwa kweengqungquthela zokutshiza kwi-cylinder emva kwe-fuel injection ye-5 ° CA kuboniswe kuMfanekiso 2. Umlinganiselo we-eddy wangoku kwi-cylinder umiselwe kwi-2.9, ukuhamba komoya kwi-cylinder i-asymmetric ngenxa yendawo ye-valve yokungena, kunye ne-fuel. isitshizi sikwachatshazelwa kukuhamba komoya ngokufanelekileyo.10.

Ukubalwa kwe-chemical reaction dynamics calculation yenziwa nge-diesel standard yecandelo lothutho imodeli yoMlilo, kwaye ukhetho oluphambili lwemodeli yokubala luboniswe kwiThebhile 3. Kwimodeli yokuqhawula i-KHRT yokutshiza, ixabiso le-coefficient C2 libekwe kwi-12.

3. Iziphumo zokulinganisa kunye nohlalutyo lwe-Figure 3, uMzobo 4 kunye noMzobo 5 ngokulandelanayo ubonisa uthelekiso kunye nohlalutyo loxinzelelo kwi-cylinder, izinga lokukhutshwa kobushushu, izinga lokushisa eliphakathi kwi-cylinder, ukukhutshwa kobushushu obuqokelelweyo kunye ne-NO iqhekeza elikhulu xa i-5-hole kunye ne-8-hole injectors. kunye ne-4-hole dual-injector yamkelwe.
