Abstract
A turbocharger includes spaced apart turbine housing and compressor housing sections which are connected by a center housing section. The center housing section journals an elongate shaft carrying at opposite ends thereof a compressor wheel and a turbine wheel rotatable in the respective housing sections. The center housing section also defines a closed cavity captively receiving a material conductive of heat and which transitions between lower and upper molecular energy levels during hot soak of the turbocharger following engine shutdown to control bearing temperature at the shaft.
