An Experimental Study on Exhaust Gas Emissions of Marine Generating Diesel Engine

The internal combustion engine has been widely used as power source, such as vehicles, industrial machine, power plant, military and marine engine. etc.. Especially, diesel engine has come to occupy most of engines for marine use, due to high thermal efficiency, durability, reliability and high output. But, the exhaust gas emissions of diesel engine came to be considered the major pollutional source, like the destruction of ozone layer, global warming, acid rain and photochemical smog, etc. Therefore, IMO adopted the regulations for the prevention of air pollution from ships as MARPOL 73/78 Annex Ⅵ in September, 1997 and this convention will be effectuated on May 19. 2005. But the restriction for NOx is applied to each diesel engine with a power output of more than l30㎾ which is installed on a ship constructed, which undergoes a major conversion on or after 1 January 2000. In this study, the generation mechanism was investigated for various exhaust gas emissions in diesel engine. And the emission characteristics of exhaust gas was understood for generating diesel engine.
