Cooling Fan Control For Improved Engine Load Acceptance
US Patent:

Filed:
Sep 8, 2005
Appl. No.:
11/221601
Inventors:
Todd Alan Loes - Waterloo IA, US

Abstract:
The present invention provides a means for momentarily reducing cooling fan load on an engine when a machine encounters sudden loads. The system includes an engine, a load driven by the engine, a cooling system associated with the machine, and one or more controllable cooling fans for delivering air to the cooling system. A controller continually monitors engine speed, reducing fan load when engine speed is both decreasing faster than a maximum rate and is lower than the desired speed. The controller then re-engages the fan load when engine speed is approximately equal to the desired speed or when a maximum disengagement time has elapsed.
