2.1 Fuel consumption of automobile operation Q, the amount of fuel consumed by the automobile during operation. The unit is L (liter). 2.2 Basic operating conditions: The monthly average temperature is between 5℃ and 28℃, the altitude h is not higher than 500m, and the operating conditions on Class 1 roads are called basic operating conditions.
2.3 Basic fuel consumption of automobile idling 9: The amount of fuel consumed by the automobile idling per 100 kilometers under basic operating conditions. The unit is L/100km (liter/100km).
2.# Cargo turnover: The product of the cargo volume and its transportation distance. The unit is t·km (magnitude kilometer). 2.5 Basic additional fuel consumption of cargo turnover: Under basic operating conditions, the amount of fuel consumed by the automobile for every additional 100 tons of cargo turnover. Unit is L/100t·kr (liter/hundred kilometers) 2.8 Basic additional fuel consumption for weight change: Under basic operating conditions, the actual weight of the vehicle G (including the weight of the trailer) is compared with the weight of the vehicle G given in this standard. For every 1t increase (or decrease) in the actual weight of the vehicle G, the amount of fuel consumption increased (or decreased) for every 100km of driving. Unit is gross/100+*km (per hundred tons and kilometers). 2.7 Road correction factor K: The ratio of the fuel consumption of a vehicle running on a certain type of road to the fuel consumption on a type 1 road (other operating conditions are the same).
2.8 Temperature correction factor K: The ratio of the fuel consumption of a vehicle running in the base monthly average temperature range to the fuel consumption when the monthly average temperature range is 28°C to 5°C (other operating conditions are the same). 2.9 Altitude correction factor Kh: The ratio of the fuel consumption of a vehicle running in the altitude range to the fuel consumption when the altitude is not higher than 500m (other operating conditions are the same). 3.1 Road categories See Table 1 for road categories. 3.2 Temperature range The temperature values referred to in this standard are the local monthly average temperatures announced by the meteorological station, which are divided into six ranges: above 28°C, 28°C to 5°C, below 5°C to -5°C, below 5°C to 15°C, below -15°C to -25°C, and below 25°C. 3.3 Altitude range The altitude is divided into five ranges: below 500m, 500m to 1500m, above 1500m to 2500m, above 2500m to 3500m, and above 3500m.

Appendix A
Example of calculation of truck operating fuel consumption (reference)
A.1 A Jiefang CA10B truck (self-weight 4.3t) is loaded with 4t of cargo. It drives 90km on a Class III mountain highway in winter (average monthly temperature -6℃) and on a plateau (2100m above sea level) to unload the cargo and then returns empty. Calculate the total operating fuel consumption of the truck. Solution: From Table 1 and Table 3, we know that K = 1.25
From Table 2, we know that qa = 21.5
From Table 4, we know that K = 1.06
From Table 5, we know that K = 1.07
Substitute into the standard formula (1)
, then the cargo trip Q1 = [21.5 + 4 × 1.8 + 1.8 × (4.3-3.8)] × -100
× 1.25 × 1.06 × 1.07
= 37.77 (L)
Idle trip Q2 = [21.5 + 1.8 × (4.3-3.8)] × - = 28.58 (L)
Then the total operating fuel consumption is:
× 1.25 × 1. 06×1.07
Q = Q1 + Q2 = 66.4 (L)
A.2 Dongfeng EQ140 truck, towing full trailer (self-weight 2t), travels 15km on the fourth-class road in the plain city in summer (average monthly temperature 19.5℃) and then enters the third-class road in the mountainous area and travels 35km. The main trailer is loaded with 9t of goods, and is fully loaded both ways. Calculate the total fuel consumption. Solution: From Table 1 and Table 3, we know that:
Urban road K=1.1
Mountain road Kr2=1.25
From Table 2, we know that q= 21
qb = qc= 1.6
From Table 4 and Table 5, we know that K,=K,=1.0
Substitute it into the standard formula (1)
Then urban road Q1=（21×15
2 ×15
= 6.37(L)
+1.6××35+1.6×2×35)×1.25 mountain road Q2=（21×35
Then the total round trip fuel consumption:
= 16.89 (L)
Q = 2 Q1 + 2 Q2 = 2 (6.37+16.89) = 46.5 (L) Additional Notes:
