The image displays the components of a dual camshaft engine timing system and a diagram illustrating their operation. The system includes two camshafts (intake and exhaust), a crankshaft sprocket, camshaft sprockets, and a timing chain. The timing chain connects the crankshaft to the camshafts, ensuring synchronized rotation. The camshafts rotate once for every two rotations of the crankshaft. This synchronization is critical for opening and closing the cylinder head valves at the correct time i
