Ammonia CI engine aftertreatment systems design and flow simulation

Investigation of exhaust emissions and ammonia flow behavior in the system incorporating with Selective Catalytic Reduction (SCR) unit is discussed. An aftertreatment designed to work without additional urea injection improve feasible temperature operating reduce size. This study focused on obtaining optimal parameters for catalysis using gaseus as reducing agent. Its effectiveness considered a function basic gases mixture SCR material characteristics. A 3D geometry porous volume has been simulated Ansys Fluent. Moreover, 1D model dual-fuel CI engine obtained. Results were local temperature, velocity, composition predict probes placement, pipes insulation parameters, characteristic dimensions.
