1 Scope
This standard specifies the emission limits and measurement methods for the
exhaust pollutants of compression ignition engines and ignition gas fuel
(including diesel and natural gas dual fuel) engines (hereinafter referred to as.
marine engines) used for ships.
This standard is applicable to the type test, production consistency inspection,
durability requirements of category 1 and category 2 marine engines (including
main engines and auxiliary engines) which have a rated net power greater than
37 kW for inland vessels, coastal vessels, river-sea ships, channel ships and
fishing ships. This standard also stipulates the emission requirements for ships
and marine engines after rebuilding.
This standard does not apply to emergency marine engines used for ships,
marine engines installed on lifeboats, marine engines on any equipment or
devices used only in emergency situations.
Category 3 marine engines implement the requirements of GD 01.
Marine engines which have a rated net power not exceeding 37 kW implement
the GB 20891 standard.

For marine engines with special purposes such as export, exhibition, rescue,
emergency, matching test, etc., it may submit an application to the competent
department to be exempted from type test. The information submitted to the
competent authority shall include model, power, manufacturer, use, emission
standard stage reached, quantity and production date.
5 Technical requirements and tests
5.1 General
The manufacturer shall take technical measures to ensure that the marine
engine's emission control system operates normally under the normal working
conditions and within the specified service life; the pollutant emission meets the
requirements of this standard.
5.2 Provisions for exhaust pollutants
5.2.1 Test procedures and sampling system
The measurement and sampling procedures of marine engine’s exhaust
pollutants are carried out in accordance with the provisions of Annex BA in
Appendix B.
5.2.2 Limits
The specific emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen
oxides (NOX) and particulate matter (PM) in the exhaust pollutants of marine
engines are multiplied by the degradation coefficient (marine engine equipped
with exhaust after-treatment system) as determined in accordance with Annex
BD of this standard, or plus the degradation correction value determined in
accordance with Annex BD of this standard (marine engines without exhaust
after-treatment system).
5.2.3 Durability requirements
5.2.4 In-use compliance requirements
Manufacturers shall take measures to ensure that the marine engines installed
on ships under normal conditions of use have their emission control devices
operating normally during their normal lifespan and meet the emission
standards during their effective lifespan.
The in-use compliance verification of the marine engine is carried out in
accordance with the on-board verification procedures specified in GD 01.
5.2.5 Requirements for rebuilding and replacement of marine engines

for characteristics during the type test of the marine engine.
6 Provisions on the control of sulfur oxide emissions from ships
6.1 Inland vessels, river-sea ships and fishing ships operating in inland rivers
shall use diesel fuel that complies with GB 252.
6.2 For coastal vessels, channel ships and fishing ships operating in offshore
areas, if marine fuel oil is required for the design of marine engine, it shall use
the low-sulfur marine fuel oil complying with national standards and regulations;
for ships with pollution control devices, if its sulfur dioxide (SO2) emissions do
not exceed the use of low-sulfur marine fuels, it may use other fuels and the
ship shall be clearly marked.
6.3 For the ships covered by this standard, if the design of the installed marine

7.1 General requirements
7.1.1 For the marine engine type (or family) that has been officially put into
production after the type test, the manufacturer must take measures to ensure
that the relevant information of the marine engine it produces is consistent with
the information of the type test (Appendix A) of the marine engine type (or
family).
