Abstract: 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.

Abstract: A plug configured to be at least partially inserted into a central housing of a turbocharger. The plug includes a body having a first end, a second end opposite the first end, and a threaded portion extending from the second end to a location on the body between the first end and the second end. The plug further includes a heat sink coupled to the second end, and a microchip mounted to a substrate that is coupled to the heat sink, the microchip configured to store information related to the turbocharger, wherein the microchip is at least partially submerged in coolant in the central housing when the plug is inserted into the central housing of the turbocharger.

Abstract: A fuel system for an internal combustion engine includes a fuel system, a valve train, and a fuel injector including a cam actuated plunger. The fuel injector has a noise suppressor fluidly connecting a plunger cavity to each of a spill passage and a nozzle supply passage in the fuel injector. The noise suppressor has an inlet configuration forming a fuel admission flow area to the plunger cavity, and an outlet configuration forming a fuel discharge flow area. The fuel discharge flow area is smaller than the fuel admission flow area, and the noise suppressor adjusts to the outlet configuration to throttle discharging of fuel from the plunger cavity to limit valve train noise.
