Abstract
Methods and systems are provided for a heat exchanger phase change material installed as a component of a variable exhaust tuning system. In one example, a method may include absorbing excess heat energy from exhaust gases during and after an engine-on event within a heat exchanger material, releasing heat energy stored in the heat exchanger material during and after an engine-off event, and heating an adjustable exhaust valve with the heat energy stored in the heat exchanger material.
