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

Uphononongo lokulinganisa kwiMpembelelo yokuTofa kweFuel okungaLinganiyo kumngxuma ngamnye weNjinja yeDizili kwiNkqubo yokuTsha(ICANDELO 3)

2 Imodeli yokutsha

Imodeli yejometri yegumbi lokutsha kwi-TDC (iziko eliphezulu elifile) litsalwa yiProE software, njengoko kuboniswe kuMzobo 1, kwaye igcinwa njengefayile yefomathi ye-STEP. Imodeli yejiyometri ithathwa kumazwe angaphandle kwisoftware yehyper mesh yolwahlulo lomnatha kwaye igcinwe njengefayile yemesh ngohlobo lweNAS. Ifayile yemesh ingeniswa kwisoftware ye-AVL FIRE yokuhlola umnatha, ukulungiswa, ukusetwa komnatha oguqukayo, ukhetho lweemodeli ezisezantsi kunye nokusetwa kweparamitha [6].

I-injector ye-4-hole eyamkelwe yi-injini ye-diesel ye-F186 inemingxuma e-4 esasazwa ngokulinganayo, kodwa i-injection ye-injection ayihambelani ne-angle yecandelo le-cylinder. Umbindi womgodi wegumbi lokutshisa i-ω ine-3 mm ye-offset ukusuka kumbindi wepiston, kwaye ukuhamba komoya kwi-cylinder kunempembelelo eyahlukileyo kwi-sprays ye-fuel yomgodi ngamnye, ngoko ke imodeli yegumbi lokutsha iyamkelwa. Umnatha ufihliwe kwindawo ekufutshane nomngxuma kunye nomda, kwaye imodeli ye-mesh kwi-TDC iboniswe kuMfanekiso 2. Kukho iiseli ze-140448 kunye ne-343488 ze-mesh kwi-TDC kunye ne-BDC (iziko elisezantsi elifile) ngokulandelanayo.

Iiparamitha ze-injini ye-diesel ziboniswe kwiThebhile 1. Indawo kunye nezicwangciso zendlela ye-injector zilandelayo: X-coordinate (0.003 m), i-Y-coordinate (-0.003 m), i-Z-coordinate (0 m), X -isalathiso (0.007), i-Y-direction (0.0397), i-Z-direction (0). Ukumiselwa kwendawo yomngxuma ngamnye kuboniswe kwiThebhile 2. Umlinganiselo wokutofa okufanayo kunye nokulinganisa ukungalingani kweqondo lokutofa kumngxuma ngamnye kwenziwa njengendlela yokumisela isitofu, kwaye izinga lokutofa liboniswa kuMfanekiso 3. Imodeli yothutho yecandelo eliqhelekileyo le-diesel fuel isetyenziselwa ukubala i-chemical reaction kinetics calculation, kunye nemodeli yokubala echaphazelekayo iboniswe kwiThebhile 3 [7, 8].
