The paper discusses influence of the charging air parameters marine diesel engine on the emission toxic compounds in aspect of protecting the atmosphere against pollution from the sea vessels, pointed to the possibility of reducing NOx emissions by changing the parameters of charging air. In this group of activities undertaken to reduce nitric oxides emissions applied inter alia cooling the air and changes in pressure at the beginning of compression stroke. This is discussed in the background of normative acts, in particular the 73/78 MARPOL Convention (International Convention for the Prevention of Pollution from Ships) referring to prevention against marine environment pollution, and later amendments to the Convention with Annex VI (Regulation for the Prevention of Air Pollution from Ships) dealing with reducing the emission of nitric oxides and sulphur oxides into the atmosphere by sea vessels engines.It was also discussed the issue of air humidification as a method to reduce NOx by injecting hot water into a stream of pumped air. This is an overview on the example of two methods proposed for using in marine engines: CASS (Combustion Air Saturation System), HAM (Humid Air Motor system). The results of experimental tests of the influence of charging air pressure on content of exhaust gas, especially content nitric oxides (NOx), of ship diesel engine supplied with marine heavy fuel oil IF40 have been presented in this paper.
