Abstract: A duct assembly for a fuel injector of an engine includes a base and multiple duct bodies. The base includes a number of spaced apart receptacles. Each receptacle defines a cavity with a receptacle axis, a rotational engagement surface, and an axial engagement surface. The duct bodies are correspondingly secured within the cavities. Each duct body defines an axis and a duct extending along the axis to provide a passage for a fuel jet from the fuel injector. Each duct body defines an axial alignment surface engaging the axial engagement surface of the receptacle in which it is disposed to axially align the duct body along the receptacle axis of the corresponding receptacle.

Abstract: A system and method includes a driver component having a first sensor rigidly mounted therewith and configured to provide a first signal indicative of a rotation of the driver component, and a second sensor rigidly mounted relative to the driver component, a driven component, and a flexible coupler disposed between the driver component and the driven component; wherein the second sensor provides a second signal indicative of a rotation of the driven component, and a controller disposed to receive the first signal and the second signal. The controller is configured and operates to calculate a difference between the first signal and the second signal, and infer a torque variation between the driver component and the driven component based primarily on the difference between the first signal and the second signal.

Abstract: A system for determining a health of a bearing associated with a connecting rod is provided. The system includes a sensor associated with the connecting rod and remotely disposed relative to the bearing of the connecting rod. The sensor is configured to generate a signal indicative of a temperature of the bearing. The system includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the bearing. The controller further determines a health of the bearing as a function of the signal of the temperature of the bearing.

Abstract: A system for determining a health of bearing associated with a connecting rod is provided. The system includes an oil collector placed proximate to the connecting rod and configured to receive an oil cast off from side thrust surfaces of the connecting rod during movement of the connecting rod. The system includes a sensor associated with the oil collector and configured to generate a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod. The system also includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod. The controller further determines the health of the bearing as a function of the signal of temperature of oil cast off from side thrust surface of the connecting rod.
