GE Marine meets EPA Tier 4i without SCR

GE V250OCTOBER 9, 2013 — GE Marine is using this week's International Workboat Show to unveil an "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 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."

Eliminating the need for an SCR also eliminates the need to store or use urea aboard a vessel, thereby preserving cargo and tank space.

GE's non-SCR solution is based on the technological advancements of the L250 and V250 engines and requires no supplemental equipment or fluids.
