Abstract
An engine mounted fan clutch is disclosed that utilizes an actuator including two shape memory alloy actuation wires to engage and disengage a valve arm and ultimately the fan. The actuator also includes a controller and a position sensor to accurately determine the position of a valve arm. The fan clutch is part of a control system that continuously monitors the engine parameters and makes adjustments to keep the engine temperature within an acceptable range.
