Ukwenza imodeli ye-High-Speed ​​Injector ye-Diesel ICE(icandelo 3)

Ezi zixhobo zilandelayo zingabhekiswa kwiimpawu zesakhiwo se-injector: I-Spring 5, i-multiplier, inaliti 7. Umthombo wenaliti yomsebenzi we-injector unyanzelekile kwaye uya kufakwa malunga ne-multiplier ukukhusela i-valve ekuvuleni kwakhona ngenxa yamaza oxinzelelo xa ukusetha kwakhona. . Ukuphindaphinda okuvala kwandisa amandla okuvala asebenza kwinaliti. Ngokungafaniyo nokuvalwa koxinzelelo xa uxinzelelo lusetyenziswa kwindawo epheleleyo yenaliti, olu luyilo luvumela uluhlu olukhulu lwemikhosi yokuvala kunye nokutshintsha kwengcinezelo efanayo.

I-inertia ye-multiplier iyonakalisa kancinane impendulo yenkqubo. Kwakhona, umphindaphindi wenza iperi echanekileyo kunye necala kwaye kwandisa imilinganiselo. Injongo yayo ephambili kukuba ukwandisa umlinganiselo we-diameter yokuphindaphinda ukuya kububanzi benaliti yenza inkqubo ilawuleke ngakumbi, ichanekile, kwaye imfutshane. Xa i-fuel injected, i-multiplier, kunye nesiphelo sayo esiphezulu, ivame ukuvala i-axial orifice ekhokelela kwi-valve yebhola 4. Ayinakuqondwa ngokupheleleyo, ekubeni uxinzelelo oluphezulu lubuyiselwa nge-jet kwaye i-multiplier inyanzeliswa ukuya kwi-orifice. . Nangona kunjalo, kukho inzuzo yokwenyani kule nkqubo yokuzinzisa ukulingana: ukuhamba kwamafutha okulawula kuyaba nzima (ukusuka kwibhetri ngejethi, i-valve ukukhupha). I-multiplier isandiso senaliti kunye nentwasahlobo. Ukusuka kwindawo yokujonga isantya sokusebenza, kukunyuka kobunzima obuhambayo. Isidingo sokusebenzisa i-multiplier ichazwe kukufaneleka kwayo kuluhlu olubanzi lweengcinezelo zokusebenza.

Isiphumo sokuphindaphinda inaliti yokuvala inyusa amandla okuvala ngoxinzelelo olufanayo olusebenza kwigumbi lolawulo kwaye, ngaloo ndlela, ukukhawulezisa ukuvala inaliti. Nokuba uqwalasela ubunzima bobunzima obuhamba ngenaliti, isantya sokusebenza siyanda. I-EHI ayisebenzi kwidizili yesantya esiphezulu ukuba isiphindaphindi esivalayo sishiyiwe. Nangona kunokwenzeka ukuba kuqinisekiswe ukusebenza kwayo, ukuzinza kokuhanjiswa kuphantsi ngokubhekiselele kwiinkqubo zamaza, ukuphambuka kwenkqubo, njl.
