Izahlulo zeAuto Isitofu seDizili ye-2645A749 yekati ye-Auto Fuel Common Rail Injector

Uyilo kunye nohlalutyo lwe-multifuel injection (icandelo 4)

Isitofu segesi siphucule isantya sokutofa, umfutho we-injector, ijometri yangaphakathi yesitofu, kunye nombhobho wesitofu. Abaphandi balinganisa i-injector ngokusebenzisa i-Bond graph modeling technique. Baphinde baqhuba izifundo zokulinganisa kuphononongo lokuziphatha oluguqukayo. U-Deyang [8] wafaka into yakhe njengelungelo elilodwa lomenzi wechiza WO 2013/188247, siphumo saso yaba kukusetyenziswa kwenaliti enye kunye ne-multi-fuel ene-pressure intensification kunye ne-orifice eguquguqukayo esebenzisa i-petroli kunye ne-diesel.

Uphando lusebenzise iipropati ezahlukeneyo zamafutha kunye neepateni zokutshiza eziguquguqukayo. Ukuveliswa kwandiswa kuhlalutyo lwamafutha e-viscosity aphantsi, kubandakanywa i-ethanol, i-LNG, kunye ne-viscosity fuels ephezulu, kuquka i-biodiesel, i-Jet Propellant -8 (JP-8) i-fuel. yezitofu zamafutha. Ke ngoko, uphando olunzulu kufuneka lwenziwe kuyilo lwesitofu segesi esinezibaso ezininzi kwizixhobo zokutsha, kubandakanya iinjini ze-IC, izitshisi zerhasi, iziko, kunye nee turbines zegesi, ezikwaziyo ukutofa ulwelo olwahlukeneyo kunye namafutha egesi esekwe kumbane. ukufumaneka kwendawo.

Eyona njongo yophando lwangoku kukuyila, umfuziselo, kunye nokulinganisa isitofu samafutha amaninzi esinokusebenza kusetyenziswa amafutha ahlukeneyo alungelelaniswe nezixhobo ezahlukeneyo zokutsha. I-injector kufuneka ikwazi ukuvelisa amandla afunekayo, i-torque eyaneleyo, kunye nokusetyenziswa kwamafutha aphantsi. Kufuneka kwakhona bakwazi ukutofa ubungakanani obufunekayo bamafutha ngexesha elithile, ngakumbi ngexesha lokufunxa okanye ngexesha loxinzelelo. Isitofu sikwaxhomekeke kwindawo ye-injector kwi-manifold okanye kwintloko ye-injini yokutofa ngokuthe ngqo.

I-fuel injector sisixhobo esisetyenziselwa ukujova okanye ukutshiza i-fuel kwisixhobo sokutshisa ukulungiselela umxube we-stoichiometric air-fuel, ngaloo ndlela ubonelela ngokutshisa ngokufanelekileyo. Isitofu samafutha yintliziyo yenkqubo yokutofa ngamafutha. Ngokusekwe kwinkqubela phambili yetekhnoloji, amalungiselelo ahlukeneyo enaliti yepetroli akhona ngokusekwe kwimfuno yesicelo ebandakanya, inaliti ye-throttle body, i-MPF (i-Multi-point fuel) inaliti, inaliti kaninzi, inaliti yePort, kunye nenaliti ethe ngqo.
