1. An opposed-piston engine, comprising:
at least one ported cylinder with a bore;
a pair of pistons disposed for mutually opposing movements in the bore;
an air intake channel configured to provide a flow of charge air through an intake port of the cylinder in response to movement of a first piston of the pair of pistons past the intake port;
an exhaust channel configured to receive a flow of exhaust gas through an exhaust port of the cylinder in response to movement of a second piston of the pair of pistons past the exhaust port;
