Intshayelelo yemveliso:
Inkqubo ye-diesel fuel injection i-atomize i-fuel kwaye isasaza phakathi kwezinto ezixuba nomoya kwigumbi lokutsha.
Ikakhulu iqulunqwe sisitofu se-fuel kunye ne-injector body.I-injection ye-fuel efakwe kwintloko ye-cylinder ihlukaniswe zibe zimbini iintlobo: uhlobo oluvulekileyo kunye nohlobo oluvaliweyo.I-injector evulekileyo inesakhiwo esilula kodwa i-atomization embi kwaye ayifane isetyenziswe.Izitofu zamafutha ezivaliweyo zisetyenziswa kakhulu kwiinjini ezahlukeneyo zedizili.I-injini ye-diesel iphefumla umoya ococekileyo ngexesha lokuthatha i-stroke.Xa i-stroke yoxinzelelo isondela esiphelweni, i-oyile ye-diesel yonyuka ibe ngaphezu kwe-100MPa ngepompo yokutofa i-fuel, ifakwe kwi-cylinder ngokusebenzisa i-injector ye-fuel, kwaye ixutywe nomoya wobushushu obuphezulu ngexesha elifutshane kakhulu. umxube otshayo.Ngenxa yoxinzelelo oluphezulu lweenjini zedizili (ngokuqhelekileyo i-16-22), uxinzelelo lomoya kwi-cylinder lunokufikelela kwi-3.5-4.5MPa ekupheleni koxinzelelo, kwaye ubushushu buphezulu njenge-750-1000K (ngelixa uxinzelelo lwegesi lomxube yeenjini zepetroli ngeli xesha iya kuba yi-0.6-1.2MPa, iqondo lobushushu lifikelela ku-600-700K), elidlula kakhulu ubushushu bokuzitshisa kwedizili.Ngoko ke, emva kokuba i-diesel fuel ifakwe kwi-cylinder, ngokukhawuleza iyavutha kwaye itshise ngokwayo emva kokuxutywa nomoya ngexesha elifutshane kakhulu.Uxinzelelo lomoya kwi-cylinder lukhuphuka ngokukhawuleza ukuya kwi-6-9MPa, kwaye iqondo lokushisa liyenyuka ukuya kwi-2000-2500K.Iqhutywa yigesi yoxinzelelo oluphezulu, i-piston ihlehla kwaye iqhube i-crankshaft ukuba ijikeleze ukwenza umsebenzi, kwaye igesi yokukhupha iphinda ikhutshwe emoyeni ngombhobho wokukhupha.
I-injini ye-diesel eqhelekileyo iqhutywa yi-injini ye-camshaft, kwaye i-oyile ye-diesel ihanjiswa kwigumbi lamafutha le-cylinder nganye ngempompo yeoli yoxinzelelo oluphezulu.Le ndlela yokubonelela nge-oyile kufuneka itshintshe kunye nokutshintsha kwesantya se-injini, kwaye isixa sobonelelo lwe-oyile siphezulu kwizantya ezahlukeneyo asinakufezekiswa.Inkqubo yonikezelo lwamafutha kaloliwe eqhelekileyo ibandakanya impompo yamafutha oxinzelelo oluphezulu, umbhobho wonikezelo lwamafutha oqhelekileyo, isitofu se-fuel, iyunithi yolawulo lombane (ECU) kunye nezinye izinzwa zoxinzelelo lwemibhobho.I-injector nganye yamafutha kwisistim idityaniswe kunikezelo lwamafutha oluqhelekileyo ngombhobho wayo woxinzelelo oluphezulu.Imibhobho ixhunyiwe, kwaye umbhobho wonikezelo lwamafutha oqhelekileyo usebenza njenge-accumulator yoxinzelelo lwe-hydraulic kwi-injector.Xa usebenza, i-high-pressure fuel pump ihambisa i-fuel kumbhobho wonikezelo lwamafutha kawonke-wonke kuxinzelelo oluphezulu, kunye nempompo ye-fuel-pressure, inzwa yoxinzelelo kunye ne-ECU yenza umsebenzi ovaliweyo ukulawula ngokuchanekileyo uxinzelelo lwe-oyile kunikezelo lwamafutha oluntu. umbhobho, ukutshintsha ngokupheleleyo uxinzelelo lonikezelo lwe-oyile kunye nokutshintsha kwesantya se-injini.Isiganeko.Iimpawu zayo eziphambili zezi zilandelayo:
1. Ixesha lokutofa kwe-fuel lihlulwe ngokupheleleyo kwimitha ye-fuel, kunye noxinzelelo lwe-injection ye-fuel kunye nenkqubo ye-injection ye-fuel ilawulwa yi-ECU ngexesha.
2. Uxinzelelo lwe-injection ye-fuel ye-cylinder nganye, indawo yokuqala kunye nobude be-injection ye-fuel inokulungelelaniswa ngokweemeko zokusebenza ze-injini, ukuze ulandele eyona ndawo yokulawula i-injection ye-fuel.
3. Uxinzelelo oluphezulu lwenaliti yamafutha kunye nokutofa kwangaphambili kwedizili kunokufezekiswa.
