GE Marine unveils ecomagination-qualified 12V250 marine diesel engine

At the International Workboat Show, GE Marine unveiled its ecomagination-qualified 12-cylinder V250 Marine Diesel engine that reduces emissions by 50 percent to meet EPA Tier 4i and IMO Tier III emission compliance. GE’s breakthrough technology eliminates the need for a urea-based after-treatment emissions reduction system. In addition, the 12V250 engine offers increased power of 3,150 kW at 900 rpm and 3,500 kW at 1000 rpm while maintaining low life-cycle cost, reliability and fuel efficiency.

Almost one year ago at the 2012 International Workboat Show, GE announced its timeline for meeting EPA Tier 4i and IMO Tier III emission compliance without the need for Selective Catalytic Reduction system (SCR) exhaust gas after-treatment for its L250 and V250 medium speed marine diesel engines (1,550 — 4,650 kW).

“The display of this engine exemplifies GE Marine’s commitment and capability to provide breakthrough technology solutions to the global marine industry,” said John Manison, general manager of GE Marine. Our new technology enables the industry to meet the upcoming emission compliance requirements as well as to reduce both capital and operating expenses.”
GE Marine’s engine technology eliminates the need for an SCR and storing or using urea aboard a vessel, thereby preserving cargo and tank space.

SCR requires using a diesel exhaust fluid, typically urea, to reduce NOx (nitrous oxide) in an after-treatment of exhaust gas. GE’s non-SCR solution is based on the technological advancements of the L250 and V250 engines and requires no supplemental equipment or fluids.
