Abstract: A hauling machine is disclosed. The hauling machine may include a dump body and an inertial measurement unit (IMU) disposed proximate to the dump body. The IMU may be configured to measure an impact of a payload material on the dump body during a first load cycle, and generate impact data based on the impact of the payload material. The hauling machine may also include a controller in operative communication with the IMU. The controller may be configured to: receive the impact data from the IMU, estimate a center of gravity, a net load, and an amplitude of the impact of the payload material based on the impact data, and determine a desired dumping point of the payload material into the dump body for a second load cycle based on the center of gravity, the net load, and the amplitude of the impact.

The fuel reformer cooler may comprise a heat transfer wall separating an effluent conduit from a coolant conduit and permitting heat transfer from the effluent in the effluent conduit to a coolant in the coolant conduit therethrough. The heat transfer wall may be formed from a base that includes a first surface facing the coolant conduit and a second surface facing the effluent conduit. The cooler may further comprise an anti-hydrogen embrittlement layer applied to the second surface of the base to shield the base from exposure to the effluent, and a plurality of symmetrical fins each extending through the anti-hydrogen embrittlement layer and contacting the second surface of the base. The plurality of symmetrical fins may project into the effluent conduit.

Abstract: The disclosure describes systems and methods of detecting a misfire in a cylinder of an engine. Such systems and methods may include determining a standard deviation for a crank angle location in a chamber of the engine, determining a standard deviation of the peak pressure in a chamber of the engine. If the standard deviation for a crank angle location is greater than a threshold value for the standard deviation for a crank angle, or if the standard deviation for the peak pressure is greater than a threshold value for the standard deviation of the peak pressure, an engine cylinder cut out check may be performed to identify one or more misfiring cylinders.
