PROPOSED AMENDMENTS TO THE TECHNICAL CODE ON CONTROL OF EMISSION OF NITROGEN OXIDES FROM MARINE DIESEL ENGINES
Paragraph 5.2.1 of the Code should be amended as follows:
5.2.1 Test condition parameter and test validity for engine family approval
Parameter "fa" shall be determined according to the following provisions:
.1 naturally aspirated and mechanically supercharged engines:
.2 turbo-charged engine with or without cooling of the intake air:
and, for a test to be recognized as valid, parameter "fa" shall be such that:
0.98≦fa≦1.02
If, for evident technical reasons, it is not possible to comply with this requirement, "fa" shall be between 0.93 and 1.07.
