Fuel Consumption for Passenger Vehicles in Operation
1 Scope
This Document specifies the classification of operating conditions and correction coefficient
for passenger vehicles, as well as the calculation method of fuel consumption for operation.
This Document is applicable to the calculation of the fuel consumption of passenger vehicles
in operation (excluding bus models) that use gasoline or diesel as the single fuel on highways
and urban roads, and is used as a reference for the management of fuel consumption quotas for
road transport enterprises.
2 Normative References
The provisions in following documents become the essential provisions of this Document
through reference in this Document. For the dated documents, only the versions with the dates
indicated are applicable to this Document; for the undated documents, only the latest version
(including all the amendments) is applicable to this Document.
GB/T 4352 Fuel consumption for trucks in operation
GB/T 19233 Measurement methods of fuel consumption for light-duty vehicles
JT/T 711 Limits and measurement methods of fuel consumption for commercial vehicle
for passenger transportation
3 Terms and Definitions
For the purposes of this Document, the terms and definitions given in GB/T 4352, JT/T 711 and
the following apply.
3.1 Fuel consumption for passenger vehicle in operation
The amount of fuel consumed by a passenger car during operation.
NOTE: The unit is L.
3.2 Basic fuel consumption of passenger vehicle
When a passenger vehicle with a total mass of more than 3500kg is under the comprehensive
announcement issued by the competent department of transportation for road transport vehicles,
and the unit is L/100km.
5.1.2 Passenger vehicles no more than 3500kg
The value of the basic fuel consumption is the comprehensive fuel consumption obtained under
the test cycle conditions given in GB/T 19233 (or checked through the light vehicle fuel
consumption label), and the unit is L/100km.
The full load fuel consumption is regarded as the same as the basic fuel consumption, and the
unit is L/100km.
5.2 Changes in fuel consumption per unit load of passenger vehicle
5.2.1 Calculation
For passenger vehicles whose basic fuel consumption and full-load fuel consumption are given
by vehicle manufacturers, the changes in fuel consumption per unit load of passenger vehicle
is calculated according to Formula (1).
Where:
Qb – changes in fuel consumption per unit load of passenger vehicle, in L/(person•100km);
Qk – basic fuel consumption of passenger vehicle, in L/100km;
Qm – full load fuel consumption of passenger vehicle, in L/km;
Mp – the total number of rated passengers of the passenger vehicle, in person.
5.2.2 Recommended value
For passenger vehicles with a maximum gross mass of more than 3500kg, when the basic fuel
consumption or full-load fuel consumption is not given by the vehicle manufacturer, the
recommended value of changes in fuel consumption per unit load of passenger vehicle Qb shall
be in accordance with Table 4.
Appendix A
(Informative)
Calculation Example of Fuel Consumption of Passenger Vehicle in
Operation with a Maximum Gross Mass of more than 3500kg
A medium passenger vehicle with a length of 7.2m has a curb mass of 5.28t and is rated to carry
25 passengers. On a Class-III highway on a hilly terrain between cities with an average monthly
temperature of 16°C, the vehicle carries 20 passengers and travels 30km. Then carry 25 people
to return to the original place; the operation period is the evening rush hour in the city, there is
congestion; the average driving speed is 20km/h; and the air conditioner is not turned on during
the driving process; find the total fuel consumption of the passenger vehicle in operation.
Method 1: When the basic fuel consumption and full-load fuel consumption are given by
the vehicle manufacturer
Calculate as follows:
a) The basic fuel consumption of passenger cars Qk provided by vehicle manufacturers is
12.7 (L/100km); the fuel consumption of full-load passenger vehicle Qm is 15.2
(L/100km) according to the announcement of qualified vehicle models for road transport
issued by the competent department of transportation.
b) According to the formula (1), calculate the additional fuel consumption of the mass
change of the passenger vehicle Qb.
c) Calculate the fuel consumption of the passenger vehicle in operation according to the
Formula (2).
According to the known conditions, the correction coefficient of the Type-2 roads is 1.10;
the correction coefficient at the monthly average temperature of 16°C is 1.00; the
correction coefficient of traffic congestion at an average driving speed of 20km/h is 1.30;
and the correction coefficient of no other influential factors is 1.00; the air conditioner is
not used during driving; so the fuel consumption of the go-path operation is as follows:
[L/(person • 100km)]
Appendix B
(Informative)
Calculation Example of Fuel Consumption of Passenger Vehicle in
Operation with Maximum Gross Mass no more than 3500kg
A passenger vehicle with a curb weight of 1.26t and a rated capacity of carrying 4 passengers
is driving 30km with 2 passengers on a Class-III highway on plain terrain between cities with
an average monthly temperature of 10 ℃; and then returns to the original place with 1 passenger.
The driving period is the evening rush hour in the city, there is congestion; the average driving
speed is 20km/h; and the air conditioner and other energy-consuming equipment are not turned
on during the driving process; then find the total fuel consumption of passenger vehicle in
operation.
Calculate as follows.
a) The basic fuel consumption of the passenger vehicle Qk obtained through checking the
light vehicle fuel consumption label is 7.8 (L/100km).
b) Calculate the fuel consumption of the passenger vehicle in operation according to the
Formula (4).
According to the known conditions, the correction coefficient of the Type-2 roads is 1.10;
the correction coefficient at the monthly average temperature of 10°C is 1.00; the
correction coefficient of traffic congestion at an average driving speed of 20km/h is 1.30;
and the correction coefficient of no other influential factors is 1.00; the air conditioner is
not used during driving; so the fuel consumption of the go-path operation is as follows:
According to the determined various correction coefficients, the fuel consumption of
return-path operation is as follows:
c) Calculate the total fuel consumption of passenger vehicle in different operating conditions
according to Formula (5).
