  "textContent": "A fuel injector includes an injector body, and a plunger movable within a plunger cavity in the injector body. The fuel injector also includes a spill valve positioned at least partially within a main fuel passage, a fill passage forming a fluid connection between the plunger cavity and the main fuel passage, and a cross passage forming a second fluid connection between the plunger cavity and the main fuel passage. The fuel injector also includes a metering edge within the plunger cavity and positioned such that the plunger passes the metering edge during pumping to the plunger for valvetrain noise suppression. A metering slot may be formed in the injector body or the plunger.",
