Opis:: In 2008 the International Maritime Organization - IMO decided to strengthen the requirements for new ships from 2011 - Tier II. However, for Emission Control Areas (ECAs), such as the Baltic Sea, stringent rules will apply from 1 January 2016 for new ships - Tier III. The new standards introduce restrictions on exhaust emissions from diesel engines - NOx and SOx. The paper presents proposal of new design an existing exhaust gas system of experimental marine diesel engine, which is situated in the Laboratory of Maritime Academy in Szczecin. The conception is due to meet to new environmental regulations. Arrangements of exhaust line, CFD model of the SCR reference plant, CFD model - inlet and outlet boundary conditions, pressure loss model for the catalytic elements, simulation results - streamlines, velocity distribution, reaction progress distribution ate presented in the paper as well design description of system of laboratory- 4-stroke and turbocharged engine. . The means of the reduction systems are based on conventional marine exhaust gas installation that includes noise silencer and soot-catcher. The after-treatment methods do not introduce significant changes in engine arrangement and operation. A new gas purifying system should be installed in the engine exhaust gas system.

Opis:: This paper describes the experimental method - using non-thermal plasma reactor to cleaning exhaust gases - focused on PM compound. The demonstrator NTP reactor assembly was built as the by-pass in the real exhaust gas after-treatment system, in marine diesel engine. The reactor used to experiment is called - DBD (dielectric barrier discharge) type, The main aim of investigation was to analyze exhaust gas PM compounds under steady load of the engine. Test bench construction enables direct exhaust stream (main exhaust duet by-pass) to plasma reactor exposure with no additional components (coolers, orifices) that can change the exhaust gas properties. A new monitoring PM analyzing system, which can measure soot and SOF in low mass level, has been engaged. It consist of a diffusion charging (DC) detector with a dilution device for soot measurement, and two differential flame ionization detection (FID) method, which uses two FID detectors with separate sample lines. Exhaust emission reduction strategy for ships, Particulate Matters - PM in exhaust gas, non-thermal plasma reactor, experimental test bed and procedure, an example of reactor power measurement, test results provided into seven stages are presented in the paper.

Opis:: Large seagoing vessels are one of the largest pollution sources in the sea environment world. Marine engines operate with extremely low quality fuels contaminated by sulphur and aromatic compounds. Vessels are responsible for an estimated 14 percent total nitrogen oxide emission and 16 percent sulphur oxide, respectively. Nitrogen oxides emissions cause serious problems including acid rain in local areas such as harbours' vicinity. All diesel engine manufacturers have been working on reducing on NOx from ships. This paper describes one of the experimental methods - using non-thermal plasma reactor. NTP reactor was built as the after-treatment module in exhaust gas system in marine diesel engine. Emission measurements were carried out on the engine with and without demonstrator NTP module. The main aim was to analyze exhaust gas compounds during real engine operation, in accordance with test cycles procedureD-2 and E-2 (ISO-8178 rules). The experiment test bench gives the innovative role in the development exhaust gas after-treatment technology for marine systems. One of the most promising methods to decrease the number of toxic compounds from exhaust gas is implementing of NTP reactor as after main treatment module. As the next steps a two-stage plasma-chemical process for the control of harmful compounds: non-thermal plasma reactor and catalyst is proposed. This combination should be more effective and probably gives reduction with more efficiency of harmful exhaust gas compounds.
