Abstract
An exhaust gas aftertreatment system for an internal combustion engine, particularly for a ship's diesel engine operated with heavy oil, has a SCR catalyst that uses ammonia as reductant. A nozzle is positioned upstream of the SCR catalyst viewed in flow direction of the exhaust gas. Using the nozzle, an aqueous urea solution is decomposed at a defined pressure and at a defined temperature to form water vapor, carbon dioxide and ammonia vapor such that ammonia evaporated by the nozzle is injected into the exhaust gas via the nozzle.
