Doosan Engine: The World’s First Eco-friendly NOx Reduction System



From Jan. 1, 2016 all newbuilds with diesel engines have to comply with IMO’s Tier III emission for sailing in North American Emission Control Areas (ECA).  An increasing number of countries have recently tightened regulations on emissions, just like the IMO’s implementation of the Tier III emission standards.

Significantly, Doosan Engine has come up with a solution.  The DelNOx SCR system for the main engines, developed by Doosan Engine last year, is the world’s first eco-friendly NOx reduction system, reducing nitrogen oxide emissions from marine engines by more than 90 percent.  It is also the world’s first low-temperature SCR system in June 2013.

Its first order was received in Sept. last year.  Doosan Engine had successfully completed an official test drive of the first marine engine with the company’s self-developed low-temperature Selective Catalytic Reduction (SCR) system, with Indian ship owners and American Bureau of Shipping (ABS) officials in attendance, at Plant 3 in Changwon in South Gyeongsang Province on Oct. 15.

The SCR marine engine system will be installed in ships that are ordered by India’s energy firm Reliance and built by Samsung Heavy Industries.
