Abstract
A camshaft driving system for a DOHC engine having a pair of cylinder rows which are displaced from each other in the axial direction of the crankshaft so that a vacant space is formed in front of one of the cylinder rows and behind the other cylinder row. One of the camshafts in each cylinder row is provided with a timing pulley. The timing pulleys of the respective cylinder rows are arranged to be driven by the crankshaft of the engine by way of transmission means such as a chain or a timing belt passed around a crank pulley fixed to the crankshaft and the timing pulleys. The driving force transmitted to said one of the camshafts in each cylinder row is further transmitted to the other camshaft in each cylinder row by way of a driving force transmission means. The driving force transmission means in the rearwardly displaced cylinder row is disposed in the vacant space formed in front of the cylinder row and the driving force transmission means in the forwardly displaced cylinder row is disposed in the vacant space formed behind the cylinder row.
