3512E

The 3512E is a large-displacement auxiliary marine engine available in a wide range of power ratings that meet U.S. emissions standards. EPA Tier 4 Final and IMO II.

One of its main innovations is the combination of an engine with optimized fuel efficiency and a Selective Catalytic Reduction (SCR) after-treatment system which is capable of reducing NOx emissions, as well as being very useful for the containment of the customer's owning and operating costs in the process. Caterpillar introduced this solution to optimize performance while fully complying with regulations, thus meeting EPA Tier 4 Final and IMO II emission standards.
