The article presents considerations regarding determining the NOx emissions from auxiliary compression-ignition marine engines. In order to determine the real impact of a given object on air pollution, it is necessary to first carry out research aimed at determining its emission characteristics. Thus, it is necessary to conduct tests in real operating conditions or to calculate the ecological indicators based on the operating conditions. The paper presents the NOx emissions intensity of an auxiliary Tier III standard marine engine, which is used in the drive system of various heavy, off-road vehicles and water vessels. Due to the structure characteristics of the considered engine group, the presented relations and results refer to only one cylinder. This data was used to calculate the NOx emission of a marine auxiliary engine, which used the operating conditions obtained from dynamometer tests and the engine construction (the number of cylinders). The presented methodology of activities can be used to assess the ecological indicators of ships in actual navigation, including primarily the maneuvers performed in the port. The article is supplemented with theoretical considerations regarding the problem of pollutant emissions from auxiliary marine engines.
