Abstract
A control system for engine braking for a vehicle powered by a turbocharged engine uses a supercharger to assist a turbocharger compressor to boost turbocharger air flow into the engine cylinders. An engine driven air pumping device draws ambient air, or alternately exhaust gas through the pump inlet, compresses the air, and delivers the compressed air through the pump outlet to the turbocharger compressor inlet or alternately the turbocharger compressor outlet. The increased air flow into the cylinders and out of the cylinder exhaust valves increases retarding power of the vehicle.
