Idizili eLawulwa ngoMbane iGenset VS EFI Diesel Genset

Ngowuphi umahluko phakathi kweseti yejenereyitha yedizili elawulwa ngombane kunye nejenereyitha yedizili ye-EFI?

Ngokwendlela yokulawula isantya se i-diesel genset , Injini ye-EFI kunye nomlawuli wombane wodidi lolawulo lwesantya sombane.Bahluke kwindlela yokulawula isantya soomatshini, esinokuthelekiswa kule miba ilandelayo:

Okokuqala, uxinzelelo lwenaliti yamafutha.

Umlawuli wombane ufaka ngokuthe ngqo idizili kwi-cylinder ngokusebenzisa impompo yesiqhelo yoxinzelelo oluphezulu, kwaye uxinzelelo lwayo lwenaliti lukhawulelwe yivalve yoxinzelelo kwi-injector.Emva kokuba i-fuel pressure kwi-high-pressure oil pipe ifikelele kwixabiso elimiselweyo le-valve yoxinzelelo, ngokukhawuleza ivule i-valve kwaye iyifake kwi-cylinder.Ukuchaphazeleka kukwenziwa komatshini, uxinzelelo lwevalve yoxinzelelo alunakuba lukhulu kakhulu.

I-injini ye-EFI iqala ivelisa i-oyile yoxinzelelo oluphezulu kwi-high-high-pressure room ye-fuel injector yimpompo yeoli ephezulu.Isitofu se-fuel injector ye-fuel injector ilawulwa yi-valve ye-solenoid.Xa i-fuel injection ifuneka, inkqubo yokulawula i-electronic ilawula i-valve ye-solenoid ukuvula kunye nokutofa i-oyile yoxinzelelo oluphezulu kwi-cylinder.Uxinzelelo lweoli ye-high-pressure ayichaphazeli i-valve yoxinzelelo kwaye inokunyuswa kakhulu.Uxinzelelo lwenaliti ye-diesel yonyuka ukusuka kwi-100MPa ukuya kwi-180MPa.Uxinzelelo olunjalo lwenaliti ephezulu lunokuphucula kakhulu umgangatho wokuxuba we-diesel kunye nomoya, ukunciphisa ixesha lokulibaziseka ukutshisa, ukwenza ukutsha ngokukhawuleza kunye nokucokisekileyo, kunye nokulawula ukushisa okutshisayo, ukuze kuncitshiswe ukukhutshwa kokukhupha.

Okwesibini, ulawulo loxinzelelo lwenaliti oluzimeleyo.

Uxinzelelo lwe-injection yenkqubo yokubonelela nge-oyile yempompo ye-oyile ephezulu yoxinzelelo lwe-injini yokulawula yombane ihambelana nesantya kunye nomthwalo we-injini ye-diesel, engathandekiyo kuqoqosho lwamafutha kunye nokukhutshwa phantsi kweemeko zesantya esiphantsi kunye nomthwalo oyinxalenye. .

Inkqubo yokubonelela ngamafutha e-injini ye-EFI inamandla okulawula uxinzelelo lwe-injection oluzimeleyo kwisantya kunye nomthwalo.Isenokukhetha uxinzelelo olufanelekileyo lwesitofu ukuphucula ubude bexesha lokutofa kunye nexesha lokulibaziseka lokutshisa, kwaye yenze ukukhutshwa kombhobho we-injini ye-diesel kuphantsi kwaye kuqoqosho phantsi kweemeko ezahlukeneyo zokusebenza.

Okwesithathu, ulawulo lwexesha lokutofa ngesitofu esizimeleyo.

Ipompo yoxinzelelo oluphezulu lwe-regulator yombane iqhutywa yi-camshaft ye-injini, kwaye ixesha layo lokujova ngokuthe ngqo lixhomekeke kwi-angle yokujikeleza ye-camshaft.Emva kokuba umatshini uhlengahlengiswe, ixesha lokutofa kwawo lilungisiwe.

I-injection ye-injection yomatshini we-EFI ihlengahlengiswa ngokupheleleyo yi-valve ye-solenoid elawulwa yinkqubo yokulawula i-electronic.Ikhono lokulawula ixesha lenaliti elizimeleyo ngokujikeleza komatshini ngumlinganiselo ophambili wokufezekisa ukulingana okulungileyo phakathi kokusetyenziswa kwamafutha kunye nokukhutshwa.

Okwesine, umthamo wokunqunyulwa kwe-oyile ngokukhawuleza.

Amafutha kufuneka anqunyulwe ngokukhawuleza ekupheleni kokutofa.Ukuba i-fuel ayinakunqunyulwa ngokukhawuleza, idizili efakwe phantsi koxinzelelo oluphantsi iya kukhupha umsi omnyama ngenxa yokungatsha okungonelanga kunye nokunyusa ukukhutshwa kweHC.

Ivalve ye-electromagnetic on-off high-speed esetyenziswa kwi-injector ye-injini ye-diesel ye-EFI kulula ukuyiqonda ngokukhawuleza ukucinywa kwepetroli, kodwa impompo yeoli yoxinzelelo oluphezulu yomlawuli wombane ayinakukwenza oku.

Okwesihlanu, ukuphunyezwa kwendlela yokulawula isantya.

Umbane olawulwayo iseti yejenereyitha yedizili yirhuluneli esondla umva umqondiso wesantya somatshini ngokusebenzisa inzwa yesantya.Irhuluneli iguqula umahluko kumqondiso wolawulo lwesantya ngokuthelekisa ixabiso lesantya esisetwe ngaphambili kwaye iqhube i-activator ukulawula i-oyile yokubeka i-oyile okanye i-sleeve yesilayidi ukuze iqonde ukulawulwa kwesantya.Isiginali yokubonelela ngeoyile ixhomekeke nje kwisiginali yesantya, kwaye uhlengahlengiso lonikezelo lweoyile lufezekiswa ngumsebenzi womatshini we-actuator.

Umatshini we-EFI usebenzisa i-sensors ezifana nesantya, ixesha lokutofa, ukushisa komoya, ukungena kwixinzelelo lomoya, ukushisa kwepetroli kunye nokushisa kwamanzi okupholisa ukuze kufakwe iiparamitha ezifunyenwe ngexesha langempela kwikhompyutheni (ECU) ngexesha elifanayo, lithelekise kunye nokugcinwa. cwangcisa ixabiso leparameter okanye iimephu zeparameter (imephu), kwaye uthumele imiyalelo kwi-activator (ivalve ye-solenoid) ngokwexabiso elihle okanye ixabiso elijoliswe kuyo emva kokucubungula nokubala.
