Abstract: A boot includes an annular body that defines a thru-bore with a thru-bore diameter, and a bore axis. The boot further defines an overall axial length, an exterior, a first axial end, a second axial end, and an aperture that radially extends from the thru-bore to the exterior.

Abstract: A gaseous fuel engine system includes an engine housing forming a plurality of intake ports, and a plurality of fuel admission tubes oriented to admit a gaseous fuel into the plurality of intake ports. The fuel admission tubes include mixers having flow-impinged surfaces exposed to at least one of a flow of gaseous fuel or a flow of intake air and each including a detachment edge. The mixers may include fins, wedge structures, and/or a contoured outer surface of the fuel admission tube. Related apparatus and methodology is also disclosed.

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.
