Foreword
In order to implement the “Environmental Protection Law of the People's
Republic of China” and the “Law of the People's Republic of China on
Prevention and Control of Atmospheric Pollution”, to prevent and control the
pollution of motor vehicles and improve the quality of the ambient air, this
standard is hereby formulated.
This standard specifies the requirements for the CHINA 6 type inspection
requirements, the consistency of production, and the inspection and
determination methods for conformity of emissions from light-duty vehicles.
Manufacturers are obliged to ensure that the vehicles they produce and sell
meet the requirements for in-use conformance of this standard.
Compared with GB 18352.5-2013 “Limits and measurement methods for
emissions from light-duty vehicles (CHINA 5)”, the main changes in this
standard include.
- CHANGE the type I test cycle, TIGHTEN the pollutant emission limits, ADD
the measurement requirements for the number of particulate emissions
from gasoline vehicles;
- DESIGNATE the real driving emission (RDE) test as type II test;
- TIGHTEN the Type VI test items and limits;
- REVISE technical requirements for monitoring items, thresholds and
monitoring conditions for on-board diagnostic systems;
- REVISE the relevant requirements for obtaining vehicle on-board
diagnostic systems and vehicle maintenance and repair information;
- REVISE the determination method of production consistency inspection
and the relevant requirements for the in-use conformance inspection;
- REVISE the technical requirements for test fuels;
- ADD requirements for control of pollutants in the refueling process;
- ADD test requirements for hybrid electric vehicles.
This part of the standard modifies and uses European Union (EC) No 715/2007
“Regulations on Type Approval of Pollutants Emitted by Light Passenger
Vehicles and Commercial Vehicles and Regulations on Obtaining Maintenance
and Repair Information for Vehicles”, (EC) No 692/2008 “Regulations on (EC)
the Implementation and Revision of (EC) No 715/2007 Regulations on Type
Approval of Pollutants Emitted by Light Passenger Vehicles and Commercial
Limits and measurement methods for emissions from
light-duty vehicles
(CHINA 6)
1 Scope
This standard specifies the emission limits and measurement methods for
exhaust emissions at normal temperature and low temperature, real driving
emission (RDE) exhaust emissions, crankcase pollutants, evaporative
emissions, and refueling pollutants, as well as the technical requirements and
measurement methods for the pollutant control device durability and on-board
diagnostics (OBD) systems of light-duty vehicles which are equipped with
ignition type engine.
This standard specifies the emission limits and measurement methods for
exhaust emissions at normal temperature and low temperature, real driving
emission (RDE) exhaust emissions, crankcase pollutants, as well as the
technical requirements and measurement methods for the pollutant control
device durability and on-board diagnostics (OBD) systems of light-duty vehicles
which are equipped with compression-ignition type engine.
This standard specifies the requirements and confirmation of light-duty vehicle
type inspection, production conformance and in-use conformity inspection and
determination methods.
This standard also specifies special requirements for the light-duty vehicles
which use liquefied petroleum gas (LPG) or natural gas (NG).
This standard also specifies the type inspection procedures for pollutant
emissions of the alternative pollutant control devices which are used as an
independent technology assembly and proposed to be installed on light-duty
vehicles.
This standard also specifies the technical requirements for vehicles that use
reactants in exhaust aftertreatment systems, as well as the emission test
procedures for vehicles that are equipped with periodic regenerative systems.
This standard applies to light-duty vehicles (including hybrid electric vehicles)
powered by ignition engines or compression-ignition engines with a maximum
design speed of 50 km/h or more.
Under the requirements of production companies, category M1, M2, N1 and N2
vehicles with a maximum design total mass of more than 3500 kg can be
subject to type inspection in accordance with this standard.
This standard does not apply to vehicles that have passed the CHINA 6 type
inspection in accordance with the provisions of GB 17691.
The use of vehicles whose fuel types are not contained in Appendix K may be
implemented with reference to the relevant provisions of this standard.
