ABSTRACT:
A method and apparatus for providing improved engine braking and improved engine operation following a braking operation is disclosed. The invention relates to a turbocharged internal combustion engine fitted with a compression relief type of engine brake wherein the turbocharger comprises a double entry turbine. In addition, a diverter valve is provided which is adapted to divert all the flow of exhaust gases into one portion of the turbine. The combination of the present invention increases the retarding horsepower developed by the engine by increasing the mass flow of the air through the engine and increasing the exhaust manifold temperature and pressure. Improved performance following braking results from the higher turbocharger speeds and increased engine temperature produced in the engine during the braking operation.
