Fuel usage monitoring system for a service pack
First Claim
1. A method for determining fuel usage rates, comprising:
- receiving a test control signal at a fuel usage monitoring controller, wherein the test control signal relates to an operating parameter of an engine, wherein the operating parameter is not directly related to fuel usage rates;
measuring a test fuel usage rate of the engine;
correlating the test control signal and the test fuel usage rate to obtain a correlation from the test control signal to the test fuel usage rate of the engine;
developing an algorithm corresponding to the correlation between the test controls signal and the test fuel usage rate of the engine;
receiving at least one control signal relating to the operating parameter of the engine; and
determining a fuel usage rate of the engine based at least in part on the at least one control signal and the developed algorithm.

Abstract
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.
