ABSTRACT:
The disclosure illustrates an exhaust brake valve positioned between a divided section exhaust manifold of an internal combustion engine and the divided flow entry to a turbine wheel of a turbocharger used in conjunction with the engine. The valve comprises a closure member displaceable between two positions, the second of which provides separate but free flow from the exhaust manifold sections and the corresponding divided flow entry of the turbine. The closure member, when displaced to the first position, blocks flow to the turbine, but at the same time interconnects the sections of the exhaust manifold. In this condition the engine acts like a compressor working against a blockage to provide a retarding effect, but the manifold interconnection minimizes peak pressure pulses to prevent engine valve bounce.
