An engine assembly may include an engine structure, first and second intake valves, and a camshaft assembly. The engine structure may define a combustion chamber, a first intake port in communication with the combustion chamber and directing intake air flow toward a central region of the combustion chamber, and a second intake port in communication with the combustion chamber. The first intake valve may open and close the first intake port and the second intake valve may open and close the second intake port. The camshaft assembly may include a first intake lobe that opens the first intake valve and a second intake lobe that opens the second intake valve. The first intake lobe may be rotationally offset from the second intake lobe in a rotational direction of the camshaft assembly.
