The course of work of commercial car synthesis traveling fuel consumption measuring device described in the utility model is as follows：
First, initial regulation：
First, vehicle is reached into ground grading, vehicle is kept relative level；
Then, foregoing measurement apparatus is flatly assembled to the centre position of fuel tank 9 in X direction, peace is carried out after fixed
Dress mark, in order to ensure the uniformity of subsequent installation；
Then, initial refueling position is determined on fuel tank 9 and the outer surface in fuel tank 9 does initial oiling mark point, is adjusted
Whole level board 201 to horizontal level, press close to fuel tank 9 and keep vertical by regulation graduated scale 3；
Wherein, level board 201 is made to adjust to the process of horizontal level by adjusting four universal adjustment joints 203

Individual universal adjustment joint 203, it is controlled to carry out the rotation around X-direction, other frees degree are locked, then adjust and are located at again
Two universal adjustment joints 203 of opposite side, the regulation of Z-direction and Y-direction is carried out, this regulative mode can be well
Horizontal adjustment when fuel tank 9 tilts is adapted to, to ensure accurate positioning；
Finally, initial markers point is done on graduated scale 3, it is concordant with the initial oiling mark point on fuel tank 9；
2nd, measurement apparatus is disassembled from fuel tank 9, then drives the circulation industrial that vehicle completes a comprehensive traveling
Condition；
3rd, fuel filling is carried out：
The measurement apparatus is installed again according to the adjustment notch on fuel tank 9；By the screen pack countersunk head 5 of the tail end of oil pipe 4
It is put into fuel tank 9, and fixes the top of oil pipe 4, fuel oil is pumped into oil pipe 4 using oil pumping hand pump, oil pipe 4 will play linker
Effect；Adjust level board 201 to level, regulation process as it was previously stated, and adjust the position of graduated scale 3, it is pressed close to fuel tank 9
And keep vertical；Initial markers point on graduated scale 3 and the initial oiling mark point on fuel tank 9 are compared：
If the two height (Z-direction) concordantly in same level, illustrates that now vehicle is horizontal, by oil pipe 4
It is attached to the outside of fuel tank 9 to refuel to initial markers, adding amount is the oil consumption that vehicle completes the state of cyclic operation of a comprehensive traveling；
If the two height (Z-direction) has difference in height, illustrate that now vehicle is in lateral inclination state, in the outer of fuel tank 9
The point corresponding with the initial markers on graduated scale is found in side, determines the corresponding point and the initial oiling on fuel tank 9
Point midway of the mark point along tank surface, the outside that oil pipe 4 is attached to fuel tank 9 are refueled to the point midway, filling
Amount is the oil consumption that vehicle completes the state of cyclic operation of a comprehensive traveling；
Finally, fuel oil sampling is carried out with measuring cup, tests fuel density and temperature in case fuel oil uniformity refers to；
After adding oil, remove device and deposit, used in case next time refuels.
Commercial car synthesis traveling fuel consumption measurement method described in the utility model is managed using the actual volume read-out of fuel tank and oil consumption
The method being combined by calculated value：After the completion of the state of cyclic operation of a comprehensive traveling, carried out according to above-mentioned refueling operation method
Fuel filling, record the fuel filling amount L1 of the state of cyclic operation；Separately go out this according to CAN signal of change by software program to follow
The fuel consumption J1 of ring operating mode；L1 and J1 ratio is calculated, that is, obtains fuel consumption adjusted coefficient K 1；By that analogy, finally
Obtain vehicle synthesis traveling fuel consumption adjusted coefficient K.
By adjusted coefficient K, the good effect that can be obtained is as follows：
1. the metewand of traveling consumption run is integrated as the vehicle, i.e., when the comprehensive Ki for travelling some state of cyclic operation is different
Chang Shi, it is necessary to which its oil supply system is analyzed and evaluated；
2. single road conditions oil consumption statistics can be realized, the highway gone out according to CAN signal of change, hilly highway and
The fuel consumption values of the single operating mode such as national highway common road, can the approximate reality for releasing each single driving cycle by adjusted coefficient K
Fuel consumption situation.
