Abstract
A shaft assembly for a barrel internal combustion engine having valves controlling the intake and exhaust of gases during operation of the engine. The shaft assembly includes a drive shaft and a cam shaft. The drive shaft extends longitudinally between opposite first and second ends along a rotational axis. The cam shaft has cam lobes for actuating the valves of the engine. The cam shaft is coupled in a spline arrangement with an end of the drive shaft for rotation therewith about the rotational axis. The cam shaft is substantially coaxial with the drive shaft.
