Abstract

An exhaust gas aftertreatment system includes a decomposition reactor, an injector, and a processor. The decomposition reactor includes a body, an impingement structure, and a heater. Exhaust gas is flowable through the body. The body includes an inlet and an outlet. The inlet is configured to receive the exhaust gas at a first temperature. The outlet is configured to selectively expel the exhaust gas at a second temperature greater than the first temperature. The impingement structure is disposed within the body between the inlet and the outlet. The impingement structure extends into the body and is located such that the exhaust gas flowing through the body impinges on the impingement structure. The heater is coupled to the impingement structure and configured to selectively heat the impingement structure. The injector is configured to inject reductant into the body. The processor is programmed to control the heater.
