ABSTRACT:
A control system for an exhaust brake which operates to impede exhaust flow from a turbocharged combustion engine when the engine throttle is closed. The control system includes means for delaying application the exhaust brake only when the vehicle throttle is closed to allow the rotational speed of the turbo charger to drop thereby reducing wear to seal components.
