The Fuel Injectors a.e a solenoid-actuated constant-stroke pintle type consisting of a solenoid, plungel n€edle valvs and
housing. When cur.ent is applied to the solsnoid coil, the vslve litts up and pressurized fuel is injected. Because the nee-
dle valve litt and the luel pressure are constant, the iniection quantity is determined by the length of time that the valv€
is open (i.e., the duration the cu.rent is supplied to the solenoid coill. The Fu€l Iniector is sealed by an O-ring and seal
ring at the top and bottom. These seals also reduce operating nois6.
