Abstract
In a turbocharged, uniflow-scavenged, two-stroke cycle, opposed-piston engine, transient changes in engine operating conditions initiate modes of air handling operation during which reversal of EGR flow in a high pressure EGR loop of the air handling system is prevented by operating one or more air handling devices to increase resistance to exhaust flow in the engine.
