Isitofu se-Diesel Fuel Injector 095000-5351 Denso Injector ye-Isuzu

Unjingalwazi we-injini yokutsha yangaphakathi kwiYunivesithi yase-RWTH Aachen uyile isampulu "HiFORS" (uxinzelelo oluphezulu / ukuvulwa ngokukhawuleza / ukubumba okuqhelekileyo kwesitofu) isitofu solu setyenziso, Iphuhliswa ngokudibanisa uxinzelelo lwenaliti ukuya kuthi ga kwi-250 MPa kunye nenaliti yokubumba kunye nokuguquguquka okuhle kunye ixesha elifutshane lokuvula kunye nokuvala ukunqanda i-throttle embi yesitulo senaliti kangangoko kunokwenzeka.Nangona ishishini leemoto okwangoku lizibophelele kuphuhliso lwepateni yokutofa okuyekisayo, kodwa liphuhlise imodeli eqhubekayo enemodyuli yemodyuli yepateni yokutofa i-injection ye-fuel, xa kuthelekiswa nezitofu zamafutha emveli, ukunciphisa kakhulu impembelelo yegumbi loxinzelelo lokuxinana ekuyilweni komxube.

Iskimu semodyuli yesitofu samafutha

I-injector ye-HiFORS yaphuhliswa ukudibanisa ukuguquguquka koyilo oluphezulu lwezicwangciso zeemodyuli zeemodyuli kunye nokuguquguquka kwemisebenzi yesitofu se-fuel, kunye nemisebenzi yesitofu somntu ngamnye ephunyezwe ngeemodyuli ezahlukeneyo.I-HiFORS injector yamafutha inokwahlulwa ibe ziimodyuli ezintathu eziphambili: imodyuli yokuqhuba, imodyuli ye-servo hydraulic kunye nemodyuli yokufaka i-fuel.Ezi modyuli ziqhagamshelwe omnye komnye ngokubopha imikhono ukuze kuqinisekiswe uxinzelelo oluphezulu olwaneleyo nakwelona xinzelelo luphezulu lwenaliti.Indibano ye-drive ihlanganiswe yi-connector, equlethe i-channel ephezulu ye-oyile yokungena, i-oil return channel, iplagi yombane ye-sensor edibeneyo kunye ne-actuator ye-piezoelectric.Ukuze kuqinisekiswe ukuthelekiswa kunye ne-injector yokuvelisa ubuninzi, i-injector yokuvelisa ininzi isetyenziswa.Ukwandiswa kwe-stroke ye-piezoelectric element kwi-connector idluliselwa kwi-servo hydraulic component ngokukhawuleza ngasemva kwimodyuli yenguqu.

Icandelo le-servo hydraulic linokuguqula imilo yepateni yokutofa.Ivalve ye-piezoelectric (ivalve yokulawula kwangaphambili) iguqula i-stroke yokwandisa imodyuli ye-piezoelectric ibe yingcinezelo yokulawula, elawula i-valve engundoqo kwaye idlulisele uxinzelelo lwenaliti kwindibano yombhobho.
