I-Diesel Injector Fuel Injector 095000-5670 23670-30090 23670-39125 Denso Injector for Toyota

Itekhnoloji yokutofa ngokuthe ngqo kwi-cylinder yahluke kakhulu kwitekhnoloji yokutofa kwe-port. Iinjini zepetroli ezifakwe ngokuthe ngqo, nokuba zithatha ukuvutha okuncinci phantsi kweemeko zomthwalo ophantsi, zithatha ukutshiswa kwe-stratified phantsi kweemeko zomthwalo ophakathi, okanye zamkele ifom yokutshisa yokulinganisa umxube wokulingana phantsi kweemeko zomthwalo ophezulu, isitofu sepetroli esitofu ngokuthe ngqo. ye-atomization idlala indima ebalulekileyo ekubunjweni komxube kwi-cylinder.
Ngokwemowudi yokuqhuba, ii-injection ze-injini yepetroli yokutofa ngokuthe ngqo zinokwahlulwa zibe zii-injection ze-electromagnetic injectors kunye ne-piezoelectric crystal injectors. Isitofu se-electromagnetic fuel injector ikakhulu silawula ukuvulwa kunye nokuhlala kwevalve yenaliti ngokunika amandla ikhoyili, kwaye i-piezoelectric crystal fuel injection ikakhulu isebenzisa i-inverse piezoelectric effect ukulawula ukunyuswa kwenaliti ye-shaft, ukuze kuqatshelwe ukuvulwa nokuvalwa kwenaliti. isitofu samafutha. . Olona ncedo luphambili lwe-piezoelectric crystal crystal injection direct injection yepetroli lixesha elifutshane kakhulu lokuphendula inaliti yamafutha, ukulinganisa okuchanekileyo kwe-fuel kunye nokuphindaphinda okulungileyo. I-Siemens injector inokufikelela kwi-pintle ephezulu yokuphakamisa ngaphakathi kwe-20us, kwaye ixesha lokuvala li malunga ne-200us. Ukuphakanyiswa kwe-pintle kunokulawulwa ngokulawula umbane wokulayisha wekristale ye-piezoelectric, ukwenzela ukuba ubuninzi benaliti yamafutha bunokulungelelaniswa ngokufanelekileyo phantsi kweyona meko iphezulu yoxinzelelo lwenaliti.
Isitofu sepetroli sokutofa ngokuthe ngqo sinokwahlulwa zibe zintlobo ze-swirl, uhlobo lwemingxuma emininzi kunye nohlobo lokuvula lwangaphandle ngokwemilo yokutshiza. Kwii-injection zohlobo lwe-swirl, xa i-fuel-high-pressure fuel flow ngokusebenzisa i-vortex generator ngaphakathi kwe-injector, I-cone engenanto yokutshiza yenziwa kwindawo yokukhupha i-injector. I-fuel etshisiweyo iphantsi kwesenzo samandla e-centrifugal kwaye ingqubana nomoya ojikelezayo, ngoko umgangatho we-atomization yamafutha ungcono. Nangona kunjalo, ulwakhiwo olungenamgongxo olubunjwe ekuphumeni komlomo luchatshazelwa kakhulu luxinzelelo lwenaliti kunye noxinzelelo lwangasemva, ngakumbi xa uxinzelelo lwangasemva luphezulu. Ke ngoko, xa ioyile itofwa ngexesha lokubetha, ngenxa yoxinzelelo oluncinci lokusingqongileyo ngasemva, isakhiwo sokutshiza esibunjiweyo sibonisa ubume obungenanto kunye nokusabalalisa i-conical shape, ehambelana nenkqubo yokuxuba i-oyile-gas. Umgangatho ongcono we-atomization uphunyezwa nakuxinzelelo olusezantsi lwenaliti. Nangona kunjalo, xa ioli ijojowe ngexesha loxinzelelo loxinzelelo, ngenxa yoxinzelelo oluphezulu lwe-ambient back, i-spray structure iyancipha, engabandakanyi ukubunjwa kwegesi edibeneyo kwi-cylinder.
