ABSTRACT:
This invention relates to a liquid-cooled piston ring carrier assembly and piston for internal combustion engines. The ring carrier assembly includes an annular metallic body and an enclosure member collectively defining an integral coolant channel. During engine operation, liquid coolant is directed to the coolant channel by way of an inlet passage in the skirt portion of the piston and an aligned inlet port in the ring carrier assembly. An outlet passage in the skirt portion of the piston and an aligned outlet port conveys coolant away from the coolant channel.
