Abstract: A system for determining a priority of monitoring a machine is provided. The system includes a data acquisition module disposed in communication with a sensor. The data acquisition module is configured to generate data based on at least an operational parameter associated with the machine. The system further includes a server configured to determine a first factor indicative of a rate of usage of the machine, a second factor indicative of a number of exceptions of the machine at corresponding severities, a third factor indicative of a risk of unscheduled downtime of the machine, a fourth factor indicative of a distance from a preventive maintenance of the machine, a fifth factor indicative of an importance of a sub-system of the machine, and the priority of monitoring the machine based on at least the first factor, the second factor, the third factor, the fourth factor and the fifth factor.

Abstract: An electro-hydraulic control system manages speed of a hydraulic fan by using a solenoid to bias a three position pool of a control valve coupled to a hydraulic pump driving the fan. In a first position, the spool releases pressure on a de-stroke actuator of the pump and allows an on-stroke actuator to increase output pressure corresponding to a speed of an engine driving the pump. In a second position, the spool isolates the de-stroke actuator and fixes the pressure output of the pump. In a third position, the spool couples the de-stroke actuator to the pump output and causes a reduction in the pressure output of the pump. The solenoid coupled to the spool sets the output pressure at which the spool is in the second position.

Abstract: A single-piece piston body for an internal combustion engine includes a crown portion having a circumferential ring belt including an oil ring groove configured to accommodate an oil control ring and a skirt portion having a first skirt wall disposed on the major thrust side and a second skirt wall disposed on the minor thrust side of the piston, and two box walls that connect the skirt walls and which are set back with respect to the ring belt. A first plurality and a second plurality of axial drain passages extend from the oil ring groove to the bottom of the crown portion, the first and second pluralities of axial drain passages being substantially centered at opposite box sides of the piston and each plurality of axial drain passages spanning an arcuate portion of about 45-75 degrees.
