Abstract
A piston and method of construction are provided. The piston has a piston body with an insert forming at least a portion of an upper combustion surface. The piston body is constructed from a first material having a first thermal conductivity and the insert is constructed from a second material having a second thermal conductivity. The first thermal conductivity is less than the second thermal conductivity. The piston body has an upper crown and a pair of pin bosses depending from the upper crown with the pin bosses presenting pin bores aligned with one another along a pin bore axis. The upper crown includes a recess in which the insert is fixed.
