Abstract
The present invention is directed to a system and method for controlling an engine braking system having an engine with at least one intake and exhaust valve, intake and exhaust manifolds, a turbocharger connected to the intake and exhaust manifolds, and at least one pressure regulation valve. The method may comprise the steps of measuring a value of an engine parameter; adjusting the pressure of the exhaust manifold responsive to the measured engine parameter value; actuating the at least one exhaust valve; and adjusting a pressure gradient across the turbocharger.
