  • CONTROL OF AIRFLOW IN A UNIFLOW-SCAVENGED, TWO-STROKE CYCLE, OPPOSED-PISTON ENGINE DURING TRANSIENT OPERATION
    Publication number: 20190120164
    Abstract: Control of airflow in a uniflow-scavenged, two-stroke cycle, opposed-piston engine during transient operation includes monitoring at least one operating parameter of the engine to recognize a transition to a transient state of engine operation. If a transient state of operation is detected, fuel injection and airflow into to the cylinders of the engine are controlled to optimize combustion and limit emissions. Airflow into cylinders of the engine may be controlled by increasing a scavenging ratio of the engine or by increasing a trapping efficiency of the engine.
