A split piston ring unit may include a first ring body, a second ring body, and a spacer insert. The first ring body may define a first circumferential gap. The second ring body may define a second circumferential gap. The spacer insert may be coupled to the first ring body and the second ring body. The first ring body and the second ring body may be arranged coaxially and oriented in an offset orientation where the first circumferential gap and the second circumferential gap are disposed circumferentially offset from one another by an offset distance. The spacer insert may be disposed in the offset distance between the first circumferential gap and the second circumferential gap to maintain the offset orientation.

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.
