Emissions control technical requirements of non-road diesel
mobile machinery
1 Scope
This standard specifies the technical requirements for pollutant emission control of the
stage IV non-road diesel mobile machinery (hereinafter referred to as the machinery),
the diesel engine it is equipped with, as well as the second diesel engine installed in the
vehicle for carrying people (cargo) on the road.
This standard applies to the type inspection, production consistency inspection,
emission compliance inspection, in-use compliance inspection and durability
requirements, for the following (including but not limited to) machinery and diesel
engines installed at non-constant speed, such as:
- Construction machinery (including excavation machinery, shoveling machinery,
hoisting machinery, forklift trucks, compaction machinery, road construction and
maintenance machinery, concrete machinery, excavation machinery, piling
machinery, aerial work machinery, rock drilling machinery, etc.);
- Agricultural machinery (including tractors, combine harvesters, etc.);
- Forestry machinery;
- Airport ground handling equipment;
- Material handling machinery;
- Snow plow equipment;
- Industrial drilling equipment.
This standard applies to the type inspection, production consistency inspection,
emission compliance inspection, in-use compliance inspection, durability requirements,
for the following (including but not limited to) machinery and diesel engines installed
at constant speed, such as:
- Air compressor;
- Generator sets;
- Fishing machinery (aerators, pond excavators, etc.);
requirements of Table D.1 of GB 17691-2018, shall be used. The urea aqueous solution
(if applicable), that meets the requirements of GB 29518-2013, shall be used.
4.1.1.5 Diesel engine's labels shall be clear and easy to view; it may also be in the form
of a two-dimensional code.
4.1.1.6 When the diesel engine is on the bench, AND the measured maximum net power
and the rated net power are not in the same power range, meanwhile the requirements
of power deviation in B.2 are not met, it shall implement the emission limits and
technical requirements of the more stringent power range.
4.1.2 Type inspection of family (source machine)
4.1.2.1 During the diesel engine's type inspection, a source engine, that can represent
the diesel engine type or family, is to be selected. If the selected model cannot fully
represent the model or family, which is described in Appendix A of GB 20891-2014, an
additional representative diesel engine shall be selected for the test.
4.1.2.2 The source machine (machinery) shall have the worst emission level in this
family. The type inspection of the source machine (machinery) can be extended to all
members of the family; other members of the family need not to be subject to type
inspection.
4.1.2.3 The inspection agency shall seal up the ECU of the diesel engine during the type
inspection, for future reference. After the diesel engine or machinery has been shut
down for 5 years, it may not be retained.
4.1.2.4 The competent department of ecological environment may conduct
confirmation inspection, according to Appendix J.
4.2 Change of product type
For any modification of diesel engine models or machinery, that has been type-tested,
it shall not have adverse effects on pollutant emissions, AND still meet the requirements
of this standard. If the changed items are public information, machinery
manufacturers/importers shall disclose the information on the change of the product. If
the changed items may affect the emission performance, the corresponding type
inspection shall be carried out, AND the information of the product changes and type
inspection results shall be disclosed.
4.3 Information disclosure
4.3.1 For the machinery within the scope of application of this standard, the machinery
manufacturing/importing enterprises shall make information disclosure, in accordance
with the requirements of Appendix A of GB 20891-2014, as well as Appendix A of this
standard. Relevant content, which involves the secrets of diesel engine manufacturers,
may be disclosed by diesel engine enterprises, after technical processing.
4.3.2 Every machine must have an environmental protection information label fixed;
the environmental protection information label shall meet the requirements of Appendix
I.
4.3.3 Each machine must have a unique machinery environmental protection code; the
machinery environmental protection code shall meet the requirements of Appendix K.
4.4 Environmental production consistency and in-use compliance
4.4.1 Machinery and diesel engine manufacturers shall ensure the environmental
protection production consistency of mass-produced machinery and diesel engines;
provide relevant production consistency assurance materials, in accordance with the
requirements of Appendix F. Manufacturers shall, in accordance with the provisions of
this standard, ensure that the emissions of newly-produced machinery and diesel
engines meet the standards; prepare relevant materials for self-examination of
emissions from newly produced machinery and diesel engines, in accordance with the
requirements of Chapter 7. The competent authority of ecological environment may
carry out spot check, on the compliance of the newly produced machinery and diesel
engines.
4.4.2 Machinery and diesel engine manufacturers shall ensure the in-use compliance of
production machinery and diesel engines; prepare a relevant in-use compliance self-
inspection plan, according to the requirements of Appendix G. Manufacturers of
machinery and diesel engines shall ensure that the emissions of machinery in actual use
meet the standards, in accordance with the provisions of this standard; prepare a self-
inspection report on in-use compliance, according to the re...
