Limits and measurement methods for exhaust pollutants
from diesel engines of tri-wheel and low-speed goods vehicles
1 Scope
This standard specifies the emission limits and measurement methods of exhaust
pollutants from diesel engines of tri-wheel and low-speed goods vehicles.
This standard is applicable to diesel engines which are installed in tri-wheel and low-
speed goods vehicles, as well as their vehicles.
If the diesel engines, which are installed in tri-wheel and low-speed goods vehicles, have
passed the type approval, according to GB 17691-2001 "Limits and measurement
methods for exhaust pollutants from compression ignition (C.I.) engines of vehicles",
THEN, the diesel engines installed in these vehicles do not need to be type approved in
accordance with this standard.
2 Normative references
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For the dated references, the subsequent amendments
(excluding corrections) or revisions do not apply to this Standard; however, parties who
reach an agreement based on this Standard are encouraged to study if the latest versions
of these documents are applicable. For undated references, the latest edition of the
referenced document applies.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1 Tri-wheel and low-speed goods vehicles
According to the provisions of GB 7258-2004:
Tri-wheel vehicles refer to freight vehicles, which have three wheels whose maximum
design speed is less than or equal to 50 km/h.
Low-speed goods vehicles refer to freight vehicles, which have four wheels whose
maximum design speed is less than 70 km/h.
3.2 Type approval of vehicle
It refers to the approval of a vehicle type for the emission level of exhaust pollutants.
3.3 Type approval of diesel engine
It refers to the approval of a diesel engine model for the emission level of diesel engine's
exhaust pollutants.
3.4 Diesel engine models
It refers to the same type of diesel engines, which have no difference in the basic
characteristic parameters of the diesel engine, as listed in Annex AA.
3.5 Diesel engine family
Refers to a group of diesel engines, which are designed by the manufacturer in
accordance with the provisions of Annex AB. These diesel engines have similar exhaust
emission characteristics; all diesel engines in the same family must meet the
corresponding emission limits.
3.6 Source engine
It refers to a diesel engine, which is selected from a diesel engine family, that can
represent the emission characteristics of the diesel engine family.
3.7 Exhaust pollutants
It refers to the gaseous pollutants and particulate matter, which is discharged from the
exhaust pipe of a diesel engine.
3.8 Gaseous pollutants
It refers to carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) in
4 Application and approval of type approval
4.1 Application for type approval
Manufacturers of tri-wheel and low-speed goods vehicles OR diesel engines for tri-wheel
and low-speed goods vehicles shall make application for the type approval, from the
emission type approval department, which is responsible for the emission of vehicle,
(hereinafter referred to as the "type approval authority"), on the exhaust pollutant
emission levels of the tri-wheel and low-speed goods vehicles and the diesel engines, that
meet the applicable scope of this standard.
4.1.1 Application for type approval of diesel engines for tri-wheel and low-speed goods
vehicles
4.1.1.1 Manufacturers of diesel engines for tri-wheel and low-speed goods vehicles shall
