Abstract
Systems, devices, and methods are disclosed for automatically adjusting a speed of an engine in response to the loading on the engine. In particular, an automatic idle system and method can comprise a governor linkage with a first end for connection to the rotatable shaft of an engine governor and a second end for connection to a throttle control of the engine, and an actuator connected to the second end of the governor linkage. The actuator can be movable in response to a load on the engine to move the governor linkage from a base position to an adjusted position. In this arrangement, when the engine is in a low-load state, the governor linkage can be moved toward a throttle-closed position.
Claims20
An automatic idle system for an engine comprising:
- an engine speed governor for connection to an engine, the governor comprising a governor shaft rotatable in response to a speed of the engine;
- a governor linkage comprising a first end for connection to the governor shaft and a second end for connection to an engine throttle control;
- and
- an actuator connected to the second end of the governor linkage, the actuator being movable in response to engine load to move the governor linkage from a base position to an adjusted position;
- wherein the governor linkage is automatically movable by the actuator toward a throttle-closed position in a low-load engine state.
An automatic idle system comprising:
- an engine drivingly engaged to a rotary blade, the engine comprising an adjustable throttle and a blade brake clutch control;
- an engine speed governor coupled to the engine, the governor comprising a governor shaft rotatable in response to a speed of the engine;
- a governor linkage comprising a first end for connection to the governor shaft and a second end for connection to a throttle control of the engine;
- and
- an actuator connected to the second end of the governor linkage, the actuator being movable in response to an engine load to move the governor linkage from a base position to an adjusted position;
- wherein the governor linkage is moveable by the actuator toward a throttle-closed position in a low-load engine state.
A method for automatically adjusting the speed of an engine comprising:
- coupling an engine speed governor to an engine, the governor comprising a governor shaft rotatable in response to a speed of the engine;
- connecting a governor linkage between the governor shaft and a throttle control of the engine, the governor linkage comprising a first end connected to the governor shaft and a second end connected to the throttle control;
- and
- automatically moving an actuator in response to the operation of a blade brake control to move the governor linkage from a base position to an adjusted position;
- wherein when the blade brake control is moved to an engaged position, the governor linkage is moved toward a throttle-closed position.
