I-Diesel Injector Fuel Injector 0445120408 iyahambelana neBosch injector Case New Holland

Impembelelo yoLwakhiwo lwe-Injector kwi-Diesel Engine Performance and Emissions

Ngokusebenzisa umjikelezo wovavanyo lwe-ESC kunye novavanyo oluzinzileyo lomthwalo ogcweleyo, inkqubo yokutsha yokutshatisa isikimu esihlangabezana neemfuno sichongiwe. Izigqibo ezifanelekileyo zezi zilandelayo:
q) Ngaphantsi komthwalo ogcweleyo, thelekisa ukusebenza kwe-injini kwizinga lokuhamba kwe-injector ye-750mL / ngaphakathi kunye ne-610mL / min. Iziphumo zibonisa ukuba xa uluhlu lwesantya luphezulu kune-1600R / min, ixabiso lomsi kunye nexabiso lokusetyenziswa kwepetroli elihambelana ne-750mL / min lincinci, kodwa i-NO kunye nexabiso lokukhutshwa liphezulu kancinci. Iziphumo zovavanyo lwe-ESC zibonise ukuba i-injini ye-particulate emissions yehla xa i-injector flow rate yayiyi-750mL min. Ukuze kuhlangatyezwane neemfuno zokukhutshwa kwe-IV yesizwe yokukhutshwa kwamasuntswana kwaye ngexesha elifanayo udibanise ukusebenza komthwalo opheleleyo we-injini, i-750mL / min ikhethwe njengeparameter ephuculweyo ye-injector flow flow. ) Iigophe ezipheleleyo zomthwalo we-148 ° kunye ne-150 ye-nozzle cone angles ziyafana. Iziphumo zovavanyo ze-ESC zibonisa ukuba uqoqosho lwe-injini lungcono xa i-engile ye-nozzle cone i-148, kwaye ixabiso lokukhutshwa kwamasuntswana liyancipha kancinci. Ngoko ke, i-engile yekhowuni yomlomo ephuculweyo ikhethwa ukuba ibe yi-148°
6) Ngexesha lenkqubo yokuphucula, iimvavanyo zenziwa kwiiprotrusions ezahlukeneyo ze-nozzle. Ngaphantsi komthwalo ogcweleyo, kwisantya esilinganiselweyo, amandla e-nozzle protrusion ye-2.0mm aphantsi kancinci, umehluko malunga ne-2kw, kodwa uye wahlangabezana neemfuno. Nangona kunjalo, kumthwalo ogcweleyo, inqanaba lomsi xa i-nozzle protrusion yi-2.0mm incinci kunezinye iindidi ezimbini ze-nozzle protrusions. Iimvavanyo ze-ESC zibonisa ukuba amanqanaba okukhutshwa kwe-NO, CH, CO, kunye ne-soot aphantse afane xa i-nozzle protrusions yahlukile. Xa i-protrusion ye-nozzle yi-2.0mm, ukukhutshwa kwamasuntswana enjini ye-diesel kuyancipha kakhulu. Ngoko ke, ngokubanzi, i-nozzle protrusion ye-2.0mm iyona nto ibhetele, kwaye iya kusetyenziswa kuyilo olulandelayo lokuphucula.
