DETERMINATION OF THE CONTENT OF POLLUTANTS IN THE EXHAUST EMISSIONS OF THE YAMZ-238 GM2 SHIP ENGINE

In order to develop reliable calculation methods for monitoring and predicting the impact of emissions from boats on the environment in cities, it is necessary to carry out experimental studies of the exhaust emissions of boat engines. The purpose of the present study was to carry out mooring (stationary) tests to measure the concentrations of carbon monoxide, carbon dioxide, nitrogen oxides and hydrocarbons in the exhaust emissions of the YaMZ-238 GM2 engine used as a power unit on single-deck tourist motor ships, crew boats, etc., by means of the gas analyzer «Infracar 5M3T.02L». It was found that the content of pollutants in the exhaust emissions of the engine did not exceed standard values, and the obtained values of average specific emissions for the YaMZ-238 GM2 engine correlated well with the corresponding values of foreign methods.
