I-Injector yeDizili eNtsha eThengisayo 23670-09380 eqhelekileyo kaLoliwe yeeNdawo zeDenso Auto

Inqanaba lokuqala: Imbali yezitofu zamafutha inokulandwa emva kweentsuku zokuqala zophuhliso lweenjini zokutsha zangaphakathi. Ngelo xesha, izitofu zepetroli zazilula kwaye imisebenzi yazo yayisisiseko.
Izitofu zamafutha ezilawulwa ngoomatshini: Ngokuhambela phambili kobuchwepheshe, kwavela izitofu zamafutha ezilawulwa ngoomatshini. Ngokomzekelo, kwiinjini ze-diesel, i-high-pressure fuel pump iqhutywe yi-injini ye-camshaft ukuhambisa i-fuel kumagumbi e-fuel ye-cylinder nganye. Nangona kunjalo, le ndlela yokubonelela ngamafutha iyatshintsha kunye nesantya se-injini, isenza kube nzima ukufikelela kulawulo lonikezelo lwamafutha kwizantya ezahlukeneyo.
Uphuhliso lwezitofu ezilawulwa ngombane: Ukuze kulawulwe ngokuchanekileyo ngakumbi inkqubo yokutofa, ii-injection ze-fuel ezilawulwa nge-elektroniki zenzeke. Ukusukela ngeminyaka yee-1950s, itekhnoloji yokutofa kwepetroli iqalile ukutsala umdla. Iinkampani zokuqala zokusebenzisa i-petroli ye-petroli kwiinjini zeemoto zavela phakathi kwe-1950 kunye ne-1953 kunye ne-1957. Kwi-1953, i-Bendix yaqala ukuphuhlisa i-injection ye-petroli elawulwa ngombane kwaye yakhululwa esidlangalaleni kwi-1957. ukuphuhliswa kwezitofu zamafutha. Isebenzisa i-electronic control unit (ECU) ukulawula ukuvulwa kunye nokuvalwa kwe-valve ye-solenoid, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lwexesha lokutofa, inani le-injection kunye ne-injection rate. Xa kuthelekiswa neendlela zemveli zokulawula oomatshini, ii-injection ezilawulwa nge-elektroniki zinokuguquguquka okuphezulu kunye nokuchaneka.
Izitofu kwisixokelelwano sikaloliwe esiqhelekileyo: Ukuvela kwenkqubo yonikezelo lwamafutha entolo kaloliwe eqhelekileyo kukhuthaze ngakumbi uphuhliso lwezitofu. Ii-injection kwinkqubo kaloliwe eqhelekileyo ixhotyiswe nge-hydraulic servo system kunye ne-electronic control element (i-solenoid valve). I-fuel ihanjiswa kumbhobho oqhelekileyo wokubonelela ngamafutha ngokusebenzisa ipompo yeoli yoxinzelelo oluphezulu, eqonda ukuhlukana okupheleleyo kwexesha lokutofa kunye nemitha ye-fuel. Uxinzelelo lwenaliti, indawo yokuqalisa inaliti kunye nobude besilinda nganye inokuhlengahlengiswa ngokweemeko zokusebenza ze-injini, kwaye eyona ndawo yokulawula yokutofa inokulandelwa. Isenokufikelela kuxinzelelo lwenaliti ephezulu kakhulu kwaye yenze isitofu sangaphambili sedizili.
Ukuphuculwa okuqhubekayo kunye nokutsha: Kwiminyaka yakutshanje, ii-injection ziye zaphuculwa ngokuqhubekayo kwaye zahlaziywa kwisakhiwo kunye nokusebenza. Ngokomzekelo, ukuze ulungelelanise imimiselo engqongqo yokukhutshwa kunye nokuphucula uqoqosho lwepetroli, ii-injection ze-fuel ziyaqhubeka ziphucula ngokumalunga nokwakheka kwe-nozzle, izinto eziphathekayo kunye nokulawula ukuchaneka; iintlobo ezahlukeneyo zezitofu zamafutha ezifana nohlobo lwevalve yebhola kunye nohlobo lwevalve yepleyiti nazo ziye zavela ukuhlangabezana neemfuno ezahlukeneyo; ukwenziwa kweminiaturization yezitofu zamafutha kunegalelo kuyilo oludityanisiweyo lweenjini; itekhnoloji yoxinzelelo oluphezulu lwenaliti ethe ngqo inokuphucula isiphumo se-atomization kunye nokusebenza kakuhle kwamafutha; ukuphuhliswa kwee-injection ezininzi ze-fuel kwenza ii-injini zikwazi ukuziqhelanisa neentlobo ezahlukeneyo zamafutha.
Uphuhliso lwee-injection ze-fuel luhlala lujoliswe ekuphuculeni ukuchaneka kwe-injection, ukuphucula i-atomization ye-fuel kunye nemiphumo yokutshisa, ukunciphisa ukukhutshwa, ukuphucula ukusebenza kweenjini kunye noqoqosho lwe-fuel, kwaye ihambelana ngokusondeleyo nokuqhubela phambili kwi-teknoloji yokulawula i-elektroniki, isayensi yezinto eziphathekayo, kunye nezinye iinkalo.
