ABSTRACT:
A fuel or air system component for a motor vehicle, constructed with shape memory alloys, to control fuel flow as a function of temperature or electrical means. The shape memory alloy changes shape at a defined temperature, or in a particular temperature range, thereby affecting a control feature internal to a component in the fuel system, and as a result, changing the fuel flow and/or pressure characteristic. The component may be a biasing spring. The shape memory alloy is an intermetallic compound or alloy which exhibits a shape transformation when heated or cooled through its transformation temperature.
