THE 1-2-3 OF OUR MARINE ENGINE TIER 4 FINAL SOLUTION
The beauty of the CAT Selective Catalytic Reduction (SCR) system is that it’s not complicated. It doesn’t affect engine efficiency and durability like other emissions-reduction solutions. There’s no alteration to core engine components and no increase in the injector, in cylinder pressure or in heat rejection. Maintenance is simple, with long life to overhaul, and installation flexes with your vessel design. Best of all, our marine engine Tier 4 Final solution improves fuel efficiency, lowering your costs. Here’s how it works in three simple steps:
- The dosing cabinet mixes the right dosage of compressed air (1A) and Diesel Exhaust Fluid (1B).
- That mixture is transferred to the SCR module (2A) where it’s injected into the exhaust stream (2B).
- Water evaporates and Diesel Exhaust Fluid is converted into ammonia. The ammonia comes in contact with the SCR catalyst to reduce NOx. The final output is carbon dioxide, nitrogen, water and oxygen.
