NIIGATA medium speed marine diesel engine

New challenge of Niigata machines has developed for clean ship concepts.

“NIIGATA has announced bland new “AHX” series medium speed “Emission Guard” diesel engine.”

A challenge for Diesel Engine manufacturers is how to achieve a high standard of emissions control while at the same time maintaining a highly efficient output. International Maritime Organization (IMO) has introduced new higher standards for emission control on diesel engines at ships constructed on or after 1st January 2011. NIIGATA marine diesel engines have reduced NOx contents in exhaust gas to meet NOx emission limit specified by Tire II and will be delivered to the customers with the third party certificates. 
Research & Development will be developed on involving subsidiary component, like reactor system in order to fulfill NOx limit to be seen at other future regulation as expressed Tire III as the next target.
