The non-SCR solution is based on the technological advancements of the company’s L250 and V250 engines that do not require supplementary equipment or fluids; in this way they remove the need for ships to store or use urea on board, thereby preserving cargo and tank space.
Depending on use, the fuel consumption of the L250 engine, rated at less than 2,000 kW, can be improved by more than 5% compared to Tier 2 standards. There are also improved torque characteristics and load response rate.
The advanced non-SCR system will be available for L250 and V250 marine diesel engines in mid-2013, ahead of the January 1st deadline for EPA Tier 3 emissions standard compliance. 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.
“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 fuel consumption of the L250 engines.” said John Manison, general manager of GE Marine.
