Abstract: A reductant delivery system for an engine system. The engine system includes an engine having an exhaust conduit and a turbocharger with a compressor. The reductant delivery system having an injector, a storage system, a sensor and a controller. The injector is configured to inject a reductant into the exhaust conduit. The storage system stores the reductant and is configured to receive pressurized air from the compressor. The sensor is configured to determine a pressure of the pressurized air in the storage system. The controller is in communication with the sensor and is configured to increase a power output of the engine in response to the pressure being below a desired pressure.
