Abstract
A method for controlling a variable-speed engine of a work machine is provided. The work 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.

18. Engine controls for a variable-speed engine, the engine controls comprising:
-
a controller;
a service interface; and
wherein the engine controls are configured to;
operate the variable-speed engine at a first preset idle speed under a first predetermined set of conditions;
operate the variable-speed engine at a second preset idle speed under a second predetermined set of conditions;
reset the first preset idle speed to a first new idle speed in response to the service interface transmitting to the controller a predetermined communication for resetting the first preset idle speed to the first new idle speed; and
subsequently, operate the variable-speed engine at the first new idle speed under the first predetermined set of conditions. - View Dependent Claims (19, 20, 21)

22. A method for controlling a variable-speed engine of a machine, the method comprising:
-
receiving inputs related to conditions of operation of the machine;
operating the variable-speed engine at a first idle speed in response to a first predetermined set of conditions;
operating the variable-speed engine at a second idle speed, lower than the first idle speed, in response to a second predetermined set of conditions;
operating the variable-speed engine at a third idle speed, higher than the first idle speed, in response to a third predetermined set of conditions, wherein the third predetermined set of conditions includes the inputs indicating the existence of predetermined conditions related to a charge level of a battery of the work machine. - View Dependent Claims (24, 25, 27, 28)
