A Review on the NOx Emission Status and Reduction Technologies of Korean Marine Diesel Engines

Abstract

In this paper, the NOx emission and the reduction technologies of NOx emission for Korean marine diesel engines are reviewed. At first, we investigate the present production status of marine diesel engines in Korea. Also, NOx emission level of marine diesel engines manufactured by four Korean engine makers is examined. Finally, the present status of the reduction technologies of NOx emission is investigated. In general, Korean marine diesel engines satisfy the current IMO NOx regulations, however the higher technologies must be studied to prepare the more severe IMO regulations of the near future.
