摘要： An engine assembly (10) includes a valve assembly (16) which selectively enables exhaust gas to be recirculated from an engine exhaust outlet (14) to an engine air inlet (12). The valve assembly (16) is positionable between a first valve position and a second valve position. The engine exhaust outlet (14) is isolated from the engine air inlet (12) when the valve assembly (16) is positioned in the first valve position. The engine exhaust outlet (14) is in fluid communication with the engine air inlet (12) when the valve assembly (16) is positioned in the second valve position. Operational pressure generated by the injector oil pump (18) of the engine assembly (10) is used to move the valve assembly (16) from the first valve position to the second valve position. A method of controlling a flow of engine exhaust in an internal combustion engine (10) is also disclosed.
