Engine including variable valve lift mechanism

Abstract

An engine assembly may include an engine structure, an engine valve, a valve lift mechanism, and first and second camshafts. The engine structure may define a combustion chamber and a port in communication with the combustion chamber. The engine valve may be supported by the engine structure and displaceable between an open position where the port is in communication with the combustion chamber and a closed position to isolate the port from communication with the combustion chamber. The valve lift mechanism may be engaged with the engine valve. The first camshaft may be rotationally supported by the engine structure and may include a first cam lobe engaged with the valve lift mechanism. The second camshaft may be rotationally supported by the engine structure and may include a second cam lobe engaged with the valve lift mechanism.
