ABSTRACT:
A rocker shaft arrangement for a valvetrain system of an engine is provided. The rocker shaft arrangement includes a split rocker shaft having two fluidly separate internal regions. Each of the fluidly separate internal regions is arranged to selectively carry an independent supply of pressurized oil for distribution to valvetrain components. The two fluidly separate regions of the split rocker shaft are each further arranged to supply pressurized oil independent of each other to one of a high lift rocker arm and a low lift rocker arm of a rocker arm assembly for an engine valvetrain system.
