Isitofu se-Diesel Injector ye-Fuel 0445120145 Iyahambelana ne-Bosch Cr/IPL26/Ziris20s

Isiphumo se-Double Injector kwiNkqubo yokuTsha kwi-396 Series ye-Diesel Engine (icandelo lesi-2)

1 1Intshayelelo

I-396 ye-injini ye-diesel isetyenziswe ngokubanzi kwiinqanawa zasekhaya, izithuthi kunye neeyunithi zamandla emizi-mveliso, njl., kuba injini inokusebenza okuthembekileyo, ubomi benkonzo ende, amandla aphezulu kunye noqoqosho kwaye inokuguqulwa ukuba isebenzise amanye amafutha afana negesi yendalo. .1-3. Ngokunyuka kokunciphisa izixhobo ze-petroleum, ukusetyenziswa kwe-biodiesel kunye ne-alcohol fuels (njenge-methanol kunye ne-ethanol) kwi-injini ye-diesel yanda.

Njengoko i-alcohol fuel ingadibani nedizili, umyinge we-alcohol fuel kwimiba exutyiweyo yezibaso zotywala kunye nedizili ungaphantsi kwe-10%. I-fuel edibeneyo inozinzo oluphantsi, ilula ngokulula kwaye ayikwazi ukugcinwa ixesha elide kunye nokongezwa kwe-cosoluent.4-6 Kunconywa ukusebenzisa i-alcohol fuel kwi-injini ye-diesel nge-double-injection. Enye indlela kukutshiza i-alcohol fuel kwi-intake manifold kunye nokutshiza i-diesel njenge-ignition fuel kwi-cylinder, kwaye enye indlela kukutshiza ngokuthe ngqo i-alcohol fuel kunye ne-diesel kwi-cylinder ngee-injection ezahlukeneyo, nge-diesel evuthayo yotywala.

Inkqubo yokutofa kwe-injini ye-396 ye-injini ye-diesel yatshintshwa, kwaye ii-injection ezimbini ezifanayo ezinemingxuma emi-4 zifakwe kwi-cylinder nganye. Ke ngoko, idizili inokutshizwa ngee-injector ezimbini, okanye i-injector enye ingasetyenziselwa ukutshiza idizili kwaye enye i-injector ingasetyenziselwa ukutshiza i-biodiesel okanye i-alcohol fuel.

Imodeli yokutsha ye-3D yoluhlu lwe-396 ye-injini ye-diesel isekwe ngokusebenzisa i-computational fluid dynamics software FIRE, kunye nenkqubo yokutshisa xa i-uniform 5-hole kunye ne-8-hole i-injector kunye ne-4-hole-dual-injector yamkelwa yathelekiswa kwaye yahlalutywa ngokulinganisa. indlela yokuphucula inkqubo yokutsha ye-396 ye-injini ye-diesel ene-injector ezimbini kunye ukubonelela ngesiseko sokusebenzisa i-biodiesel kunye ne-alcohol fuel kwixesha elizayo.7, 8.
