METHOD AND SYSTEM FOR DETERMINING A MAXIMUM EFFICIENCY OPERATING SPEED OF AN ENGINE

摘要

A control sub-system (108, 208) for determining a maximum efficiency operating speed of an engine (104, 204) is presented. The control sub-system (108, 208) includes a measurement unit (110, 210) configured to generate electrical signals indicative of an engine power and a controller (112, 212) coupled to an engine control unit (ECU) (106, 206). The controller (112, 212) is configured to determine a maximum efficiency operating speed of the engine (104, 204) corresponding to an engine power based on a value of a fuel command received from the engine control unit (106, 206). The controller (112, 212) is also configured to communicate control commands to the engine control unit (106, 206) to operate the engine (104, 204) at the maximum efficiency operating speed corresponding to the engine power.
