The adoption and implementation of the strict provisions regarding the marine environment by the Maritime Maritime Organisation (IMO) resulted in imposing the limits for the SOx, NOx, and CO2 as the exhaust gas components. However, the limitations do not refer to fishing cutters/vessels. Given the number of the European fishing fleet, operating at the ECA areas, it should be expected that the limitations related to this group of vessels are implemented. In order to determine the degree of threat to the environment...

The quality of fuel atomization in diesel engine, commonly represented by the mean drop size, is critical for fuel-air mixture, and for the rate of fuel evaporation and combustion. Poor quality fuel-air mixtures are a source of harmful exhaust gas components, such as nitrogen oxides and particulates. In spite of advanced technologies, mentioned components still are not eliminated from combustion products. The article presents the results of the impact of fuel pump delivery rate and fuel viscosity on the course of ...
