Abstract: A system and method for controlling fuel injection timing in an engine operable in a selected one of a plurality of engine notch positions are provided. The system includes a module for determining whether a fuel value indicative of a fuel quantity to be delivered to the engine is within a predetermined fuel value range for the selected one of the plurality of notches. The system further includes a module for setting a predetermined fuel injection timing value that uniquely corresponds to the selected one of the plurality of notches upon verification that the fuel value is within the predetermined fuel value range.

Abstract: A method and system for identifying a plurality of critical faults in machines is provided. The method allows for collecting from a predetermined plurality of the machines respective machine data indicative of each fault logged over a predetermined period of time. Respective identifying steps allow for identifying in the collected machine data respective faults most frequently occurring relative to one another and for identifying in the most frequently occurring faults, respective faults that, relative to one another, affect a higher number of machines. A classifying step allows for classifying the faults identified in the last-recited identifying step based on an expected level of machine degradation associated with the identified faults, and a storing step allows for storing any faults classified as likely to result in an imminent machine mission failure in a predetermined database of critical faults.

Abstract: Calls are transferred from a first call to a second call in a trunked digital radio communications system that includes a first transmitting user terminal that communicates with a receiving user terminal or group of user terminals in the first call over a first working channel via a base station. A second call is transmitted from a second transmitting user terminal to the base station over a second working channel, that identifies the receiving terminal. Transfer data is transmitted from the base station to the receiving terminal or group of user terminals in the first call on the first working channel, the transfer data identifying the second call and the second working channel. The transfer data is detected in the first call on the first working channel at the receiving user terminal and the receiving user terminal transfers to the second call on the second working channel based upon the transfer data.

Abstract: A system and method for controlling operation of an engine during a bog condition is provided. The method allows for monitoring values of a commanded engine RPM signal and of an actual engine RPM signal. The method further allows for determining whether the difference between respective values of the commanded engine RPM signal and the actual engine RPM signal exceeds a predetermined threshold RPM value. An inflection determining step allows for continuing to monitor values of the actual engine RPM signal to determine an inflection RPM point. A varying step allows for controllably varying the commanded engine RPM signal from a predetermined point about the inflection RPM point towards a desired commanded speed value.

Abstract: A system and method for controlling a turbocharged compression-ignition engine having an intercooling system that uses a predetermined coolant fluid is provided. The engine is configured to receive a predetermined combustion-supporting fluid into a plurality of cylinders through a respective intake manifold. The method allows for detecting a full or high load engine condition using the amount of fuel injected into a cylinder per cylinder cycle and/or throttle notch position. The method also allows for sensing a predetermined parameter indicative of a respective ambient condition. The method further allows for selecting a desired value of a predetermined operational parameter that influences peak pressures developed within the cylinders. The desired value being selected based on the value of the parameter indicative of the ambient condition. A comparing step allows for comparing an actual value of the operational parameter against the desired value of that operational parameter.

Abstract: A method and system for controlling a compression ignition engine in railroad locomotives and other land or marine-based large propulsion or power generation equipment operable in a selected one of a plurality of engine throttle notches is provided. Each throttle notch is indicative of a respective load condition of the engine. The engine has an intercooling system using a predetermined cooling fluid and the engine is configured to receive a predetermined combustion-supporting fluid (e.g., air) into a plurality of cylinders through respective intake manifolds. The method allows for sensing the selected throttle notch, and for selectively actuating the intercooling system to adjust a predetermined operational parameter (e.g., intake manifold air temperature) based on the sensed throttle notch and/or environmental conditions.
