Abstract
A liquid fuel injector for a fuel system in an internal combustion engine includes two injection control valves for controlling two outlet checks. A common nozzle supply cavity is fluidly connected to an inlet passage and supplies each of the two sets of nozzle outlets opened and closed by the outlet checks. A first nozzle outlet set forms a narrower spray angle and has a first combination of outlet number and outlet size, and a second nozzle outlet set forms a wider spray angle and has a second combination of outlet number and outlet size. The first nozzle outlet set has a greater steady flow than the second nozzle outlet set.
