The article presents the results of experimental tests of the influence of charging air pressure on content of exhaust gas, especially content nitric oxides (NOx), ofship diesel engine supplied with marine heavy fuel oil IF 40. Nitric oxides emissions for a given engine will depend on charging air parameters. Change of air parameters in this method of reducing NOX emissions involves cooling the air and changes in pressure at the beginning of compression stroke. The process of cooling the scavenging air means decreases the inlet air temperature and at the same time decreases the maximum cylinder temperature. Atmosphere protection against pollution on sea vessels covers one of the most important areas of human ecological activity which has its own history as well as some achievements. The most crucial ones include 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.
