the unit is L/100km.
5.2 Changes in fuel consumption per unit load of truck
5.2.1 Calculation
When the basic fuel consumption and full-loaded fuel consumption are given by the automobile
manufacturer, the changes in fuel consumption per unit load of the truck is calculated according
to Formula (1).
Where:
Qb – changes in fuel consumption per unit load of truck, in L/(t•100km);
Qi - the fuel consumption of the truck in operation under the ith operating mode, in L;
Si - the driving mileage of the truck under the ith operating mode, in km;
ΔWi - the load mass of the truck under the ith operating mode, in t;
Kri – the fuel consumption correction coefficient of the road of the truck under the ith operating
mode, see Table 1;
Kti - the fuel consumption correction coefficient of the temperature of the truck under the ith
operating mode, see Table 2;
Kvi - the fuel consumption correction coefficient of the traffic congestion of the truck under the
ith operating mode, see Table 3;
Kxi - the fuel consumption correction coefficient of other influential factors of the truck under
the ith operating mode, which is specified by the vehicle user itself;
Qai - the additional fuel consumption of the truck under the ith operating mode, the specific value
is specified by the vehicle user itself, in L.
NOTE: The additional fuel consumption of truck is the main energy-consuming equipment of truck that
are not used to drive vehicles, such as the fuel consumption of air conditioners, refrigeration units for
refrigerated trucks, and truck-mounted loading and unloading machinery; the unit is L.
The total fuel consumption of trucks in different operating modes is calculated according to
Formula (3).
Where:
Q - total fuel consumption of trucks in different operating modes, in L.
5.4 Calculation example of the fuel consumption of truck in operation
See Appendix A for the calculation example of fuel consumption of truck in operation with a
maximum gross mass more than 3500kg.

Calculation Example of Fuel Consumption of a Truck in Operation with a
Maximum Gross Mass of more than 3500kg
An ordinary truck has a maximum gross mass of 9.29t, a curb mass of 4.29t, and a rated load
mass of 5t. It travels 30km with a full load on a slightly hilly Class-III highway between cities
with an average monthly temperature of -6°C. After unloading, it returns to the original place
with no load. The operating period is the evening rush hour in the city, there is congestion, the
average driving speed is 22km/h; the hot air air-conditioner is turned on during driving; and the
fuel consumption of the air conditioner is calculated as 0.1L for one-way operation. Find the
total fuel consumption of the truck in operation.

fuel consumption
Calculate as follows.
a) The basic fuel consumption of truck Qk provided by truck manufacturers is 16.1
(L/100km); the fuel consumption of the full-loaded truck Qm is 20.4 (L/100km) after
checking the announcement of the qualified vehicle model for the road transportation
issued by the competent department of transportation.
b) According to the Formula (1), calculate the changes in fuel consumption per unit load of
truck Qb.
c) Calculate the fuel consumption of the truck 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 -6°C is 1.06; the
correction coefficient of traffic congestion at an average driving speed of 22km/h is 1.15;
and the correction coefficient with no other influential factors is 1.00; the hot air air-
conditioner is turned on during driving, and the fuel consumption of the air conditioner
is 0.1L for one-way operation; so the fuel consumption of the truck in operation is as
follows:

Calculation Example of Fuel Consumption of a Truck with a Maximum
Gross Mass no more than 3500kg
A truck with a maximum gross mass of 3.4t, a curb mass of 1.9t, and a rated load mass of 1.5t

temperature of -3°C, and returns to its original place with no load after unloading. The operating
period is the evening rush hour in the city, there is congestion; the average driving speed is
22km/h; the hot air air-conditioner is turned on during driving, and the fuel consumption of the
air conditioner is calculated as 0.1L for one-way operation. Find the total fuel consumption of
the truck in operation.
Method 1: When the truck manufacturer gives the basic fuel consumption and full-loaded
fuel consumption
Calculate as follows.
a) The basic fuel consumption of trucks Qk is 9.2 (L/100km), which is obtained through
checking the light-duty truck fuel consumption label, and the full-loaded fuel
consumption of trucks Qm provided by truck manufacturers is 11.2 (L/100km).
b) Calculate the changes in fuel consumption per unit load truck Qb according to the formula
(1).
c) Calculate the fuel consumption of the truck 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 -3°C is 1.03; the correction
coefficient of traffic congestion at an average driving speed of 22km/h is 1.15; and the
correction coefficient with no other influential factors is 1.00; when the hot air air-
conditioner is turned on during driving, the fuel consumption of air-conditioner is
