Patent application: Heat exchanger for an exhaust tuning system

Ben Welter - Monday, April 29, 2019

U.S. patent application 20190120103 (applicant Ford Global Technologies, Dearborn, Mich.):

"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."
