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.

A method for injection reductant into an exhaust gas and for evaporating and decomposing the reductant at an elevated temperature includes providing an exhaust pipe having an interior surface and disposing the pipe in fluid communication with and upstream of a catalyst. The method includes the steps of disposing an internal cone within the pipe generally parallel to the pipe, mounting an injector to the exterior of the pipe in fluid communication with the cone, injecting the reductant into the cone, and directing the exhaust gas in a passage between the interior surface of the pipe and the cone. The exhaust gas is directed within the cone. The flow of exhaust gas has an elevated temperature compared to an ambient. A further step includes creating a drag force on the injected reductant to increase travel time of the injected reductant from the injector to the catalyst.
