Abstract: Disclosed herein are novel slew drive components and systems. In some cases, a slew drive system can comprise a sensor configured to measure deformation in a deformation element of a sensor carrier component, which can result from axial displacement of a worm gear of the slew drive system. In some cases, measured deformation of a deformation element can be used to determine torque applied to a worm gear by a slew drive worm wheel, as described herein.

Abstract: A smudge pot with a pot, a pot lid, a chimney, a return pipe, and an access port. The pot has an interior configured to hold liquid fuel. The pot lid has a combustion hole and a return hole extending therethrough. The chimney is aligned with the combustion hole. The return pipe has a first end positioned inside of the chimney, a second end coupled with the pot lid at the return hole, and a pipe wall extending between the first end and the second end. The first end has a first opening aligned with a center of the return pipe and the second end has a second opening aligned with the center of the return pipe. The pipe wall comprises an arc adjacent to the first end and may be parallel to the chimney adjacent to the second end.

Abstract: A fuel system is provided for use with a variable speed dual fuel engine. The fuel system comprises a first fuel injector configured for supplying diesel fuel to the engine, a second fuel injector configured for supplying natural gas to the engine, and a fuel controller configured to implement a diesel injection schedule and a natural gas injection schedule based on at least a fuel map, an optimal engine speed and a current engine speed.
