Introducing on-engine NOx abatement with iSCR
For vessels using aftertreatment to comply with NOx limits, a simple installation is key to unlocking advantages to both ship construction and operation. Integrated selective catalytic reduction (iSCR), the first on-engine NOx abatement solution for two-stroke marine engines, reduces the complexity of installing and commissioning.
Several factors need to be considered when integrating NOx abatement technologies into the vessel’s engine system, including:
- Space demands in the engine room and/or funnel;
- Special requirements for piping (safety considerations and extra space);
- Multiple systems, controls and interfaces, often from different suppliers;
- The combined engine and aftertreatment system can only be tested once it has been installed and connected.
Deploying an X-Engine with iSCR enables Tier III NOx compliance in a simple package that minimises the space needed in the engine room as well as providing significant savings in footprint and weight. For a 52cm bore engine, integrating SCR can reduce combined weight by more than a third.
WinGD has designed iSCR with a simplified maintenance concept for the catalyst and other elements, enabling crew to reduce the time spent looking after the system.
