I-YS ibonelela ngeevalvu ze-solenoid ezihambelanayo kwii-injector zezithuthi zedizili ezahlukeneyo. Uphawu lwempendulo yesantya esiphezulu sevalve ye-solenoid sisitshixo solawulo oluchanekileyo lwesitofu sexesha lokutofa kwamafutha, ubude bexesha lokutofa kwepetroli, kunye nokufezekiswa kweepateni ezininzi zokutofa.
Umthamo wokuhamba kwevalve ye-solenoid ngundoqo ekuqinisekiseni umthamo we-injection ye-fuel yomjikelezo we-injini ye-diesel phantsi kweemeko zokusebenza ezahlukeneyo. Uyilo lwenkqubo entsha ye-YS kunye nolwakhiwo oluphuculweyo lwenza ivalve ye-solenoid eguquguqukayo kunye ne-frequency yokusebenza ihlangabezane neemfuno zolawulo lwenaliti yamafutha.
