Abstract
A rocker arm adapter for use in the timing mechanism of an internal combustion engine is disclosed. The adapter is a method for altering the cam profile of the exhaust valve of the engine with respect to the intake valve. It includes a fluidic delay device mounted in either the first end or the second end of the rocker arm. The delay device includes a piston which is allowed to move various distances in a cavity formed in the rocker arm, the distance being directly related to the speed of movement of a push rod member. As the speed of the engine, and the speed of movement of the push rod, increases, the piston will be allowed to move a greater distance into the cavity so that the delay in actuation of the rocker arm by the push rod is increased.
