Abstract:
A piston crown for a piston of a pair of pistons in a two-stroke, opposed-piston, compression ignition combustion engine has a barrier layer and a conductive layer. The barrier layer at least partially surrounds a combustion chamber formed by the piston crown and an end surface of an opposing piston. The conductive layer connects the crown to the rest of the piston body. The barrier layer and the conductive layer are joined either through welding or through the fabrication process. Optionally, the piston crown includes an insulating layer between the barrier and conductive layers.

Claim (Index 5):
A piston for a two-stroke, opposed-piston, internal combustion engine, comprising:\n a piston body with a crown at one end, the crown including;\n an end surface formed on the crown, the end surface including an elongated bowl that cooperates with an opposing piston end surface to define a combustion chamber, \n a barrier layer located in the end surface such that the combustion chamber is enclosed at least in part by the barrier layer; \n a conductive layer located adjacent to the barrier layer, the conductive layer connecting the crown to the rest of piston body; and \n at least one void formed from a discontinuity between the barrier layer and the conductive layer, \n in which:\n the barrier layer and the conductive layer each have a bowl, a pair of notches, and a sidewall portion, \n the barrier layer and the conductive layer are joined along their respective sidewalls, and \n the crown is attached to the piston body above piston ring grooves by welding.
