摘要：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.
