    Abstract: Cleanout tools and related methods of operation. At least some of the example embodiments are cleanout tools including a tool body that defines an internal annular channel, a joiner coupled to the tool body, a sleeve telescoped within the joiner and tool body, and a ball disposed within the annular channel. The ball held within the annular channel by the sleeve, and the ball configured to move along the annular channel under force of fluid pumped into the cleanout tool. The ball creates a pulsing of fluid streams exiting the tool body. Moreover, in some example systems the fluid streams created by the tool body intersect the inside diameter of a casing at non-perpendicular angles.

    Abstract: Systems and methods for using a diesel particulate filter (DPF) heater as a load bank to maintain a minimum exhaust temperature for a diesel oxidation catalyst (DOC) paired with a prime mover are provided. The system includes a prime mover coupled with a generator, a compressor powered by the prime mover, a DOC disposed downstream from the prime mover, and a controller. The prime mover is separate from another prime mover used for operating a vehicle. The controller is configured to determine a load of the generator, to determine a load of the compressor, to determine a load of the prime mover based on the determined load of the generator and the determined load the compressor, and to control the load of the prime mover to maintain a minimum exhaust temperature for the DOC.

  • Publication number: 20230272737
    Abstract: A turbine-compressor assembly includes a turbine-compressor device fluidly coupled with a heat source, a compressor, and a turbine via plural valves. A power device is coupled with the turbine-compressor device via a shaft. A controller can control operation of the plural valves to control the movement of fluids within the assembly to selectively switch between the turbine-compressor device operating in one of plural operating modes. In a first mode of operation, the turbine-compressor device can generate electrical power and direct the electrical power to the power device to control an amount of power provided to or extracted from the shaft by the power device. In a second mode of operation, the turbine-compressor device can receive electrical power from the power device to consumer the electrical power.

  • Publication number: 20230272739
    Abstract: An improved internal combustion engine utilizes at least one orbital-epicycle crankpin eccentrically offset from an orbital shaft, rotationally linked to the main shaft via an orbital-epicyclic gear set, such that the piston and connecting rod, influenced by the force from the thermodynamic process, transfers a straight linear force to the orbital-epicyclic crankpin via a conventional connecting rod and the two-piece flying crank arm to the main shaft. The concept provides a simple way of adjusting or inverting the piston to crank relationship for a different engine application and fuel characteristics with a variety of (dwell duration) ECVC cycle durations to appear at TDC or BDC.

  • Publication number: 20230272742
    Abstract: A novel structural arrangement for the various components of an Ultra-Micro Gas Turbine Generator, based on a single part impeller element which comprises the compressor, the turbine and the electrical generator core in a single annular structure, produced as a single piece by an additive manufacturing process. The single annular structure has a hollow shell structure, with a supporting structure within in. The internal hollow space of the shell structure provides for a flow of cooling air from the outside through the internal space, for cooling the turbine region of the impeller. This air flow could be assisted by the use of internal blades, which can also serve as the supporting structure to increase the strength of the shell structure. The air flow can either be ejected at the center of the turbine, or can provide a high pressure supply for air bearings of the impeller element.
