Foreword
This Standard is formulated for the purpose of implementing the Environmental
Protection Law of the People’s Republic of China and the Atmospheric Pollution
Prevention and Control Law of the People’s Republic of China, preventing and
controlling the pollution of emissions from motor vehicles to the environment and
improving the quality of ambient air.
This Standard specifies the measurement methods and technical requirements for
emission pollutants, double idle speed emission pollutants, crankcase pollutants,
evaporative pollutants, durability of pollutant control device and on-board diagnostics
(OBD) system of light-duty hybrid electric vehicles with spark-ignition engines at room
temperature and low temperature; it also specifies the measurement methods and
technical requirements for emission pollutants, free acceleration emission smoke,
pollutant control device and on-board diagnostics (OBD) system of light-duty hybrid
electric vehicles with compression-ignition engines at room temperature.
This Standard is a supplement to “Limits and measurement methods for emissions
from light-duty vehicles” (GB 18352), it is applicable to the type test, production
consistency and in-use compliance inspection of light-duty hybrid electric vehicles in
the fourth stage and beyond.
This Standard refers to the technical content of hybrid electric vehicle emissions in “05
series of amendments” (Addendum 82. Regulation No.83 Revision 3 - Amendment 3
Supplement 8 to the 05 series of amendments - Date of entry into force. 22 July 2009)
issued on 4 November 2009 of R83 Regulation “Uniform provisions concerning the
approval of vehicles with regard to the emission of pollutants according to engine fuel
requirements” of UN Economic Commission for Europe (ECE).
This Standard is a revision of “Measurement methods for emissions from light-duty
hybrid electric vehicles” (GB/T 19755-2005). The main amendments are as follows.
- CHANGE the specification for type I test;
- ADD the specification for type VI test;
- ADD the specification for double idle speed test;
- ADD the specification for OBD test;
- ADD the specification for free acceleration smoke test;
- ADD the inspection and determination methods for in-use compliance;
- ADD new test methods for off-vehicle charging hybrid electric vehicles;
Technical requirements and measurement methods
for emissions from light-duty hybrid electric vehicles
1 Scope of application
This Standard specifies the measurement methods and technical requirements for
emission pollutants, double idle speed emission pollutants, crankcase pollutants,
evaporative pollutants, durability of pollutant control device and on-board diagnostics
(OBD) system of light-duty hybrid electric vehicles with spark-ignition engines at room
temperature and low temperature.
This Standard specifies the measurement methods and technical requirements for
emission pollutants, free acceleration emission smoke, pollutant control device and
on-board diagnostics (OBD) system of light-duty hybrid electric vehicles with
compression-ignition engines at room temperature.
This Standard specifies the inspection and determination methods for the type test,
production consistency and in-use compliance of light-duty hybrid electric vehicles.
This Standard applies to light-duty hybrid electric vehicles with a maximum design
speed greater than or equal to 50 km/h and installed with spark-ignition engines or
compression-ignition engines. For vehicles with only parking idle speed stop function
as described in QC/T 837, their emission measurement is carried out according to the
requirements of conventional vehicles and does not fall within the scope of this
Standard.

3 Terms and definitions
For the purpose of this Standard, the following terms and definitions and those
established in GB 18352 and GB/T 19596-2004 apply.
3.1
hybrid electric vehicle
Vehicles at least capable of obtaining power form the following two types of on-board
stored energy.
- consumable fuels;
- rechargeable/energy storage device.
3.2
light-duty hybrid electric vehicle
Hybrid electric vehicles within the scope of GB 18352.
3.3
type test
Refers to the stereotypes test, after the design of a hybrid electric vehicle model is
completed, to the trial new product to verify whether the product can meet the technical
requirements of this Standard.
3.4
energy storage device
Devices, mounted on hybrid electric vehicles, capable of storing electrical energy,
including all power batteries, supercapacitors and flywheel batteries or other
combinations.
3.5
(1) The item does not apply to the fourth stage.
(2) The item does not apply to the fourth stage.
(3) For light-duty hybrid electric vehicles of the fifth stage, carbon tank and catalytic converter
tests shall also be carried out according to GB 18352.5-2013.
Type I test. refers to the air pollutant emission test at normal temperature after cold start
Type II test. refers to the measurement of CO and THC of double idle speed and λ value
(excess air coefficient) of high idle speed for vehicles with spark-ignition engines; refers to free
acceleration smoke for vehicles with compression -ignition engines
Type III test. refers to the crankcase pollutant emission test
Type IV test. refers to the evaporative pollutant emission test
Type V test. refers to the durability test for pollution control devices
Type VI test. refers to the CO and HC emission test at low temperature after cold start
6 Test description
6.1 Type I test (air pollutant emission test at normal temperature after cold start)
6.1.1 Off-board vehicle charging (OVC) hybrid electric vehicles without function
of manual selection of driving mode
The test shall be carried out under the following conditions.
- Condition A. the energy storage device is in the maximum state of charge;
- Condition B. the energy storage device is in the minimum state of charge.
Refer to Annex C for the schematic diagram of the state of charge of the energy storage
device in type I test.
6.1.1.1 Condition A test
6.1.1.1.1 Energy storage device discharges through vehicle running
The vehicle is running on a test runway or chassis dynamometer as required below
until meet one of the following discharge termination conditions.
- Vehicle speed is stabilized at (50 ± 2) km/h until the engine of the hybrid electric
vehicle starts;
- If the engine is not started, and the vehicle can not reach a stable speed of (50 ±
2) km/h, then the vehicle speed shall be reduced so that the vehicle can run at a
certain time/distance at this vehicle speed when the engine is not started
(determined by the testing organization and the manufacturer) until the engine
starts;
