Abstract
An engine assembly may include an engine structure, first and second exhaust gas conduits, a turbine and a flow control mechanism. The engine structure may define a first cylinder and first and second exhaust ports in communication with the first cylinder. The first exhaust gas conduit may be in fluid communication with the first exhaust port. The second exhaust gas conduit may be in fluid communication with the second exhaust port. The turbine may be in fluid communication with the first exhaust gas conduit. The flow control mechanism may prevent the exhaust gas from the first cylinder from flowing through the second exhaust gas conduit during a first mode and may allow the exhaust gas to flow through both the first and second exhaust gas conduits during a second mode.
