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 fullloaded 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.

mass of 5t. It travels 30km with a full load on a slightly hilly ClassIII 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 airconditioner is turned on during driving; and the
fuel consumption of the air conditioner is calculated as 0.1L for oneway operation. Find 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 oneway operation; so the fuel consumption of the truck in operation is as
follows:

period is the evening rush hour in the city, there is congestion; the average driving speed is
22km/h; the hot air airconditioner is turned on during driving, and the fuel consumption of the
air conditioner is calculated as 0.1L for oneway operation. Find the total fuel consumption of
the truck in operation.
Method 1: When the truck manufacturer gives the basic fuel consumption and fullloaded
fuel consumption
Calculate as follows.
a) The basic fuel consumption of trucks Qk is 9.2 (L/100km), which is obtained through
checking the lightduty truck fuel consumption label, and the fullloaded 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

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 Type2 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
