Airflow control in a uniflow scavenging two-cycle opposed piston engine during transient operation

摘要

Control of airflow in a uniflow scavenged two-cycle opposed piston engine during transient operation includes monitoring at least one operating parameter of the engine to recognize a transition to transient engine operation. If transient operation is detected, fuel injection and air flow into the engine cylinders are controlled to optimize combustion and limit emissions. The air flow to the engine cylinder may be controlled by increasing the scavenging ratio of the engine or by increasing the trap efficiency of the engine. [Selection] Figure 4
