Updating environmental requirements for engines of river passenger and sightseeing vessels.

The article addresses the need to update environmental requirements for engines used on river passenger and sightseeing vessels in the context of implementing federal programs aimed at modernizing the transport system of the Russian Federation, one of the key objectives of which is the development of inland waterway transport. It is noted that ensuring environmental safety is a mandatory condition for the sustainable development of transport, including river transport. This task is addressed through the establishment of maximum permissible emission limits for harmful substances contained in the exhaust gases of internal combustion engines. A comparative analysis of domestic and foreign regulatory documents governing environmental requirements for internal combustion engines is carried out. Based on the results of this comparison, it is concluded that the current standards for exhaust gas toxicity and smoke opacity of river vessel engines require updating. The concept of revising regulatory values is presented, proposing the use of vessel grouping as a basis for emission standardization. Based on the results of field studies and statistical processing of ship inspection reports, updated standards for exhaust gas smoke opacity and toxicity of marine diesel engines are proposed. It is demonstrated that updating environmental requirements is particularly relevant for passenger and sightseeing vessels operating in large metropolitan areas.
