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.

Abstract: In an air handling system of an opposed-piston engine, mass airflow sensor operation is monitored by comparing mass airflow measured by the sensor with mass airflow through a supercharger.
