Abstract
A system and method for controlling the quantity of compressed air that may enter into an engine cylinder during the intake stroke of a piston during an engine braking event. A control throttle may be positioned to restrict the quantity of compressed air that may enter into the cylinder during the intake stroke. The control throttle may also be positioned downstream of the engine and configured to adjustably restrict the quantity of exhaust gas that may be delivered to a turbine. By restricting the exhaust gas delivered to the turbine, the power generated by the turbine that is used by the compressor to compress intake air may also be reduced. Moreover, by controlling the power available to the compressor, the quantity of compressed intake air may be controlled, which allows for control of the quantity of compressed air that enters into the cylinder during the compression stroke.
