Abstract: An engine assembly includes an engine structure including an engine block defining a cylinder bore and a cylinder head, a piston located in the cylinder bore, and a camshaft assembly. The piston, cylinder head, and cylinder bore cooperate to define a combustion chamber including first and second longitudinal end surfaces defined by the cylinder head and the piston. A first protrusion may extend longitudinally from one of the first and second longitudinal end surfaces and radially inward from a circumference of the combustion chamber to a location between a first intake port and a first exhaust port in communication with the combustion chamber. The camshaft assembly may include a first intake lobe that opens a first intake valve and a second intake lobe that opens a second intake valve. The first intake lobe may be rotationally offset from the second intake lobe in a rotational direction of the camshaft assembly.

Abstract: 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.

Abstract: A camshaft assembly may include a first shaft, a second shaft, a first lobe and a second lobe. The second shaft may be coaxial with and rotatable relative to the first shaft. The first lobe may be fixed for rotation with the first shaft and adapted to open a first valve in communication with an engine combustion chamber. The first lobe may define a first valve opening region having a first angular extent. The second lobe may be fixed for rotation with the second shaft and adapted to open a second valve in communication with the engine combustion chamber. The second lobe may define a second valve opening region having a second angular extent greater than the first angular extent.
