초록

A vehicle auxiliary power unit includes a turbine to provide a turbine output, a fuel-fired burner that provides a heat source for the turbine, and a heat exchanger that receives the turbine output. The heat exchanger generates a heat exchanger output to produce a predetermined output condition such as heating/cooling a cabin compartment, heating an exhaust component to a desired temperature, and/or heating an engine block, for example.
