1.3.1
Nitrogen Oxide (NOx) emissions
means the total emission of nitrogen oxides, calculated as
the total weighted emission of NO2 and determined using
the relevant test cycles and measurement methods as specified in this
Code.
1.3.2
Substantial modification of
a marine diesel engine means:
-
.1 For engines installed on ships constructed
on or after 1 January 2000, substantial modification means
any modification to an engine that could potentially cause the engine
to exceed the emission standards set out in regulation 13 of Annex VI. Routine
replacement of engine components by parts specified in the technical
file that do not alter emission characteristics shall not be considered
a "substantial modification" regardless of whether one part or many
parts are replaced.
-
.2 For engines installed on ships constructed
before 1 January 2000, substantial modification means
any modification made to an engine which increases its existing emission
characteristics established by the simplified measurement method as
described in 6.3 in excess of the allowances
set out in 6.3.11. These changes include, but are not limited to,
changes in its operations or in its technical parameters (e.g., changing
camshafts, fuel injection systems, air systems, combustion chamber
configuration, or timing calibration of the engine).
1.3.3
Components are those interchangeable
parts which influence the NOx emissions performance, identified
by their design/parts number.
1.3.4
Setting means adjustment of
an adjustable feature influencing the NOx emissions performance
of an engine.
1.3.5
Operating values are engine
data, like cylinder peak pressure, exhaust gas temperature, etc.,
from the engine log which are related to the NOx emission
performance. These data are load-dependent.
1.3.6 The EIAPP Certificate is the
Engine International Air Pollution Prevention Certificate which relates
to NOx emissions.
1.3.7 The IAPP Certificate is the
International Air Pollution Prevention Certificate.
1.3.8
Administration has the same
meaning as article 2, sub-paragraph
(5) of MARPOL 73/78.
1.3.9
On-board NOx verification
procedures
mean a procedure, which may include an equipment
requirement, to be used on board at initial certification survey or
at the periodical and intermediate surveys, as required, to verify
compliance with any of the requirements of this Code, as specified
by the engine manufacturer and approved by the Administration.
1.3.10
Marine diesel engine means
any reciprocating internal-combustion engine operating on liquid or
dual fuel, to which regulations 5,
6 and 13 of
Annex VI apply, including booster/compound systems if applied.
1.3.11
Rated power means the maximum
continuous rated power output as specified on the nameplate and in
the technical file of the marine diesel engine to which regulation 13 of Annex VI and the
NOx Technical Code apply.
1.3.12
Rated speed is the crankshaft
revolutions per minute at which the rated power occurs as specified
on the nameplate and in the technical file of the marine diesel engine.
1.3.13
Brake power is the observed
power measured at the crankshaft or its equivalent, the engine being
equipped only with the standard auxiliaries necessary for its operation
on the test-bed.
1.3.14
On-board conditions mean that
an engine is:
1.3.15 A technical file is a record
containing all details of parameters, including components and settings
of an engine, which may influence the NOx emission of the
engine, in accordance with 2.4 of this
Code.
1.3.16 A record book of engine parameters is
the document for recording all parameter changes, including components
and engine settings, which may influence NOx emission of
the engine.
