Niigata has a long history of designing and manufacturing high-speed diesel engines for extremely high-speed vessel. One of technical challenges is black smoke emitted during quick ship operation. In the following, Niigata shows the results of investigations to realize non-visible smoke for an extremely high-speed 4 MW class 20FX diesel engine during ship transient operation.
Clean and Non-visible Exhaust Gas
There are no regulations in Japan concerning black carbon and particulate matter in marine engines now, but the enforcement of their emission reduction is expected because they are worried about effect to the body such as respiratory and circulatory organs. From the perspective of keeping ship crews working on deck healthy, and also from the perspective of preventing sea environmental pollution, the authors consider that eliminating of black smoke is an important issue. Moreover, eliminating of black smoke leads to a reduction in fuel consumption, bringing economic benefits and...
