  • Method for controlling a variable-speed engine
    Patent number: 7165530
    Abstract: A method for controlling a variable-speed engine of a machine is provided. The machine may include a park-brake. The method may include receiving a signal indicating an engagement status of the park-brake. The method may also include operating the variable-speed engine at a first idle speed. Additionally, the method may include operating the variable-speed engine at a second idle speed, lower than the first idle speed, only if the signal indicates that the park-brake is engaged.
