3、e Marathon is very difficult because factors of missmeasuring like heat expanding and vapor bubbles are influential strongly to small quantity of its fuel consumption.As for the factor of missmeasuring by heat expanding of fuel, It has been mostly solved by confirmation of air pressured electric fue

4、l injection system without electric fuel pump that increase temperature of fuel. If it has only a few volume of fuel except tank in its hole fuel system, compensating of heat expanding by just fuel tank is almost accurate. But as for the factor of missmeasuring by vapor bubbles, It has not been enou

5、gh to be solved it yet. The mechanism of the error of measuring the fuel consumption is as follows. When person put off a cap of fuel tank to measure the fuel consumption, same fuel vapor occurred by haste decompression in the fuel distributor even if manual valve of fuel tank is closed, caused by s

6、omewhat unexpected factors.And there are some volume in fuel injector and fuel distributor that we cant see in them and cant make sure the amount of vapor bubbles in them with naked eye.Particularly, in the case that there is some volume in the fuel distributor, the error will be happen even if any

7、competitor do not have a wrong intention.But if there is a big volume in the fuel distributor or any other compressible device like air dumper, it is out of problem.For ExampleIf the potential for the fuel consumption of the competition vehicle is 2000(km/l) and the distance of competition track is

8、15(km), the real fuel consumption is 7.5(cc). But if the remained fuel vapor is 3(cc) that we cant see it in the fuel distributor, the amount of measuring the fuel consumption is 4.5(cc). Therefore the record is 3333(km/l). The error of measuring the fuel consumption is 67(%).So we have discussed ab

9、out how to compensate these bubbles. And then person in charge of Finish Mileage Marathon offered to us one of good ways to make sure the vapor bubbles in the fuel distributor.The important point of improving way is as follows. After topped up ,temperature measured and repressurized, Measurers will

10、check that fuel-level doesnt drop significantly; significant drop is over about 0-1mm, which is the usual drop when system is compressed.(measuring point of fuel tank I.D.is about 3mm) Above is very important to accurate measuring of fuel consumption.For reference, whole procedure is as follows.Here

11、 are the top-up procedures we have planned to apply for pressurized fuel systems.At the start: - To speed up the procedure competitor is recommended to come to startline top-up with fuel left in tank and valve closed with the system after tank compressed to normal running pressure.1)fuel is added we

12、ll above the mark2)system is compressed to the pressure marked on the meter3)fuel valve is opened4)competitor will start the engine, engine must run until the fuel has dropped under the mark; this is to ensure same pressure in the whole system as well as to uncover possible hide-ups for fuel5)valve

We found that technology of European teams make steady progress over this strict management of the race. 計測方法基本、温度補正行点燃料燃料全体 計測点点、日本点重点移必要思。Fundament

17、al points of fuel measurement are temperature compensation and measuring whole mount of fuel system.
