c) Delete the altitude range (see 4.2.3 of 2007 Edition);

d) Increased traffic congestion and fuel consumption correction coefficient of traffic congestion (see 4.3 of this Edition);

e) Delete the passenger vehicle operating mode (see 4.3 of 2007 Edition);

f) Delete the constant-speed fuel consumption under the curb weight (no load) and total weight (full load) of passenger vehicles (see 5.1 of 2007 Edition);

g) Change the calculation method of basic fuel consumption and full-load fuel consumption of passenger vehicles (see 5.1 of this Edition; 5.2 of 2007 Edition);

h) Delete the fuel consumption correction coefficient of passenger vehicles in operation (see 5.4 of 2007 Edition);

i) Change the classification of vehicle types and corresponding calculation methods for calculating the fuel consumption of passenger vehicles in operation; and adjust the calculation formula (see 5.3 of this Edition; 5.5 of 2007 Edition);

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.

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.

Appendix A 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 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 °C; 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). ......
