Abstract
A cylinder liner for an internal combustion engine and a method of making the same are disclosed. The cylinder liner may generally include a cylindrical body configured to receive a piston assembly. The cylindrical body may further include a main body portion configured for selective engagement with an engine bore, and an upper flange configured to support the cylindrical body within the engine bore. The cylindrical body may also define an undulating cooling gallery adjacent the upper flange. The undulating cooling gallery generally defines a single coolant flow path extending about a perimeter of the cylindrical body.
