GE Marine technology enables its L250 and V250 marine diesel engines to be compliant without exhaust after-treatment.
At the International WorkBoat Show 2012 in New Orleans, GE Marine announce its timeline for meeting EPA Tier 3 and Tier 4i, as well as IMO Tier III emission compliance without the need for exhaust gas after-treatment for its L250 and V250 marine diesel engines.
GE’s engine technology eliminates the need for a Selective Catalytic Reduction system (SCR) and storing or using urea aboard a vessel, thereby preserving cargo and tank space. This advanced non-SCR system will be available in mid-2013, months before the Jan. 1, 2014, deadline for EPA Tier 3 emissions standard compliance.
“GE has been working for eight years to reach this breakthrough in diesel engine technology to help businesses worldwide comply with EPA and IMO emission standards,” said John Manison, general manager of GE Marine. “This new technology allows the marine industry to meet the upcoming emission compliance requirements and reduce both capital and operating expenditures. In addition, our engineering efforts have further reduced the already class-leading fuel consumption of the L250 engines.”
GE’s L250 engines rated at less than 2,000 kW will be certified as EPA Tier 2 during 2013 but will meet EPA Tier 3 emission levels, ahead of the January 2014 standard path requirement. In addition, the 8L250 and 12/16V250 engines rated at more than 2,000 kW will meet EPA standard path Tier 4i (interim) requirements in 2014.
