U.S. EPA Tier 4 Final & IMO III Marine Engine Emissions Technology
Selective Catalyst Reduction (SCR) Technology for U.S. EPA Tier 4 Final Marine Engine Emissions
Beginning January 1, 2016, U.S. Environmental Protection Agency (EPA) Tier 4 Final emission standards apply to Cat® C280, C175, 3500, and C32 ACERT™ marine engines with ratings equal to and greater than 1400 bkW. The marine-specific solution designed by Caterpillar includes Selective Catalyst Reduction (SCR) technology to meet Tier 4 Final emission standards. SCR has less impact on engine efficiency and durability than other emissions reduction solutions.

FROM SKETCH TO SHIPYARD: THE STORY OF CATERPILLAR MARINE’S TIER 4 FINAL & IMO TIER III EMISSIONS SOLUTION
It started on a napkin, progressed to a sheet of notebook paper and today is enabling Cat® marine customers to meet U.S. Environmental Protection Agency (EPA) Tier 4 Final and International Maritime Organization (IMO) Tier III emissions standards.
Case Study: SCR Delivers on Emissions and Efficiency
For the offshore, workboat, ferry and small cargo ship sectors driven by medium speed and high speed engines, both Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR) technologies enable compliance. However, we believe SCR provides measurable fuel cost savings while using proven engine platforms.
