3.1 Maximum allowable NOx emission limits for marine diesel engines

  3.1.1 The graph in figure 1 represents the maximum allowable NOx emission limit values based on the formulae included in paragraph 3(a) of regulation 13 of Annex VI. The total weighted NOx emissions, as measured and calculated in accordance with the procedures in this Code, shall be equal to or less than the applicable value from the graph corresponding to the rated speed of the engine.

  3.1.2 When the engine operates on marine diesel oil in accordance with 5.3, the total emission of nitrogen oxides (calculated as the total weighted emission of NO2) shall be determined using the relevant test cycles and measurement methods as specified in this Code.

  3.1.3 An engine's applicable exhaust emissions limit value from figure 1 and the actual calculated exhaust emissions value for the engine shall be stated on the engine's EIAPP Certificate.
