Abstract
A compact construction for an opposed-piston engine includes a cylinder liner with longitudinally-spaced exhaust and intake ports in which the exhaust port has inner and outer edges presenting a port height that causes the exhaust port to be fully open before a piston associated with the exhaust port reaches bottom dead center during an expansion stroke and the end surface of the associated piston to be spaced outwardly of the outer edge when the piston is at bottom dead center.
