20090194067 | SERVICE PACK POWER MANAGEMENT - A power management system, in certain aspects, may utilize direct load sensing feedback from the prime mover (e.g., engine), thereby reducing the possibility of overloading the prime mover. The use of direct load sense feedback from the prime mover can then be used with additional feedback, such as prime mover RPM feedback and individual output load sensing feedback, to directly control the output loads and set the primary power sources rpm set-point to better manage the power available and reduce the possibility of overloading the primary power source. | 08-06-2009 |
20100199655 | HYDRAULIC PUMP CONTROL SYSTEM - A hydraulic load ramping system, in certain aspects, may utilize load sensing feedback from an engine, thereby reducing the possibility of overloading the engine as well as smoothing the transition between hydraulic load levels. In particular, by ramping between hydraulic load levels, unwanted movement of hydraulically-driven equipment may be minimized. In addition, by efficiently monitoring the load sensing feedback and ramping between hydraulic load levels, the hydraulic output may be maximized. | 08-12-2010 |
20100199753 | FUEL USAGE MONITORING SYSTEM FOR A SERVICE PACK - A fuel usage monitoring system, in certain aspects, may be configured to determine the fuel usage rate of a work vehicle service pack engine using control signals relating to operating parameters of the service pack engine and associated equipment. In certain embodiments, the control signals may relate to operating parameters of the engine, a fuel injection pump associated with the engine, a governor associated with the fuel injection pump, a fuel reservoir associated with the engine, and other components associated with the engine. In particular, the control signals may relate a position of a control rack of the fuel injection pump. The control signals may be correlated with fuel usage rates prior to operation of the fuel usage monitoring system. In addition, the correlations may vary as certain parameters of the engine, such as operating speed, vary. The correlations may be implemented as algorithms within software of the fuel usage monitoring system. | 08-12-2010 |
20100199950 | COMPRESSOR CONTROL FOR DETERMINING MAXIMUM PRESSURE, MINIMUM PRESSURE, ENGINE SPEED, AND COMPRESSOR LOADING - A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption. | 08-12-2010 |
