Claim Text:
1. A method of cooling a cylinder of an opposed-piston engine, in which the cylinder includes a sidewall, longitudinally-spaced exhaust and intake ports opening through the sidewall, a bore, and one or more injector ports in a central band of the cylinder, including: striking the sidewall with a plurality of liquid coolant impingement jets arranged in at least one sequence along a circumference of the sidewall in the central band; transporting the liquid coolant from the central band along the sidewall in the directions of the exhaust and intake ports; accumulating transported liquid coolant in a first reservoir that extends in a circumferential direction around the sidewall, in the vicinity of the exhaust port; accumulating transported liquid coolant in a second reservoir that extends in a circumferential direction around the sidewall, in the vicinity of the intake port; receiving, in the first reservoir, liquid coolant transported along the sidewall from the liquid coolant accumulated in the second reservoir; transporting accumulated liquid coolant through bridges of the exhaust port; and transporting accumulated liquid coolant out of the cylinder.
