Often it is less than a quarter of fuel tank total height.
For example, when the amount of the gasoline stored in fuel tank is alarm threshold value, the height of fuel level is total for fuel tank
/ 10th of height, now, if diesel oil is injected in fuel tank, the density of blended fuel oil gradually increases, and works as blended fuel oil
Liquid level when reaching a quarter height of fuel tank, the blended fuel oil in fuel tank is equivalent to 1/10th height in fuel tank
It is below gasoline, is diesel oil from 1/10th height to the fuel oil of a quarter height, blended fuel oil can be calculated accordingly
Density.Height in the immersion fuel oil of moving parts 103 can be calculated according to the density of the blended fuel oil density and moving parts 103
The ratio of degree and the total height of moving parts 103, and then blended fuel oil can be calculated and reach fuel tank a quarter height, and move
Dynamic component 103 just rises when blocking passage 1011, the top of height, i.e. moving parts 103 that moving parts 103 is risen
With the difference in height between passage 1011.
The difference in height between the top for experimentally determining moving parts 103 and passage 1011 can also be adopted,
So that the amount of the gasoline stored in fuel tank is to add diesel oil in the case of alarm threshold value, and the height of fuel level reaches combustion
During a quarter of fuel tank total height, moving parts 103, which just rises, blocks passage 1011.
