An internal coumbustion engine assembly which includes an exhaust gas recirculation mechanism, an engine air inlet and an engine exhaust outlet. The engine assembly further includes a valve assembly which includes a valve housing having a housing inlet and a housing outlet, the valve assembly is positionable between a first valve position and a second valve position. The engine assembly still further includes a first conduit which connects the engine exhaust outlet in fluid communication with the housing inlet and a second conduit which connects the engine air inlet in fluid communication with the housing outlet. The engine assembly still further includes a camshaft having a cam member secured thereto with the cam member positionable between a first cam member position and a second cam member position. The cam member interacts with the valve assembly so as to cause the valve assembly to be positioned at the first valve position when the cam member is positioned at the first cam member position and the valve assembly to be positioned at the second valve position when the cam member is positioned at the second cam member position. Engine exhaust gases are allowed to advance from the engine exhaust outlet to the engine air inlet when the valve assembly is positioned in the first valve position. Air is prevented from advancing from the engine air inlet to the engine exhaust outlet when the valve assembly is positioned in the second valve position.
