Christopher Wichael - Dunlap IL, US

International Classification:

F02D031/00

US Classification:

123/352000, 123/357000

Abstract:

An engine control system, dredging system, and a method for controlling torque output of an engine. An engine control system controls torque output of an engine. At least one sensor is coupled with the engine. The sensor monitors and transmits operating data of the engine. An electronic device coupled to the sensor is operable to control the engine as a function of the transmitted operating data. The engine is controlled by the electronic device to operate substantially at a predetermined torque limit over a predetermined range of engine speeds, by determining and regulating an amount of fuel to the engine. Alternatively, the engine is controlled by the electronic device to operate substantially at, and between predetermined upper and lower torque limits over a predetermined range of engine speeds, by determining and regulating an amount of fuel to the engine.

Abstract:

A engine control system and a method of controlling a torque output of an internal combustion engine is disclosed. The engine control system comprises a torque receiving device operably connected to the engine, a sensor to sense an engine parameter, and an electronic device operably connected to the sensor. The electronic sensor is operable to determine a second engine speed from sensed engine parameters, a droop speed, and a selected one of a plurality of torque maps requiring a minimum amount of fuel. The electronic sensor is also operable to transmit a signal indicative of the second engine speed to a fuel system to control the amount of fuel delivered to the engine.
