Isitofu se-fuel esinepleyiti ye-orifice kufutshane nendawo yokuphuma. Ipleyiti ephuma emlonyeni inomphezulu wepleyiti yokuqala neyesibini ebekwe kumgama oqingqwe kwangaphambili ukusuka kwenye kunye ne-orifice, i-orifice ephuma ecaleni kwe-asis ye-longitudinal kwaye ibandakanya umphezulu wokuqala kunye nomphezulu wesibini ocalulwayo ukusuka kumphezulu wokuqala. Umphezulu wokuqala uquka ummandla wokuqala onophawu lomphezulu wokuqala ojoliswe kwicala lokuqala oblique kwi-axis ye-longitudinal. Umphezulu wesibini uquka ummandla wesibini oneempawu zomphezulu wesibini ojoliswe kwicala lesibini elityebileyo kwi-axis ye-longitudinal. I-injector yamafutha inendlu eyandisa i-axis ye-longitudinal. Indlu ibandakanya indawo yokungena, indawo yokuphuma kunye nepaseji elahliweyo phakathi kwendawo yokungena kunye nendawo yokuphuma. Isitofu se-fuel sikwabandakanya i-electromagnetic actuator ekufuphi nendawo yokungena, i-electromagnetic actuator ebandakanya i-armature kunye nekhoyili ye-electromagnetic indibano yevalvu, indibano yevalvu kubandakanya nelungu lokuvala kunye nesihlalo sevalvu, ilungu elivalayo elisebenza ukuvala ukuhamba kwamafutha ukuya kwindawo yokuphuma. indawo yokuqala kunye nesebenzayo ukuvumela ukuhamba kwamafutha kwiplate ye-orifice kwindawo yesibini. Iindlela ezininzi zokwenza ii-orifice ezine-engile kwiphepha lesinyithi zichazwe apho i-orifice ene-engile inokwakheka ukusuka kwi-orifice e-engile echanekileyo. I-orifice nganye ene-angle ine-oblique axis enxulumene nobuncinci kwindawo yokuqala kunye nomgangatho wesibini wephepha lesinyithi.
