By the way, in order to improve the combustibility of an automobile engine, it is necessary to efficiently guide the generated ozone into the combustion chamber of the automobile engine. However, ozone is an unstable gas that has one more oxygen than oxygen (its molecular structure is O2), which is in a stable state in air, as can be seen from the chemical formula of O3.

Therefore, the ozone generated by the ozone generator is very fragile and, for example, in a high temperature atmosphere, there is a problem that it is converted into oxygen by the combination of ozone.

Therefore, even if ozone is generated by the ozone generator to improve the combustibility of the liquid fuel, the generated ozone cannot be efficiently introduced into the combustion chamber of the automobile engine. It has been very difficult to improve the combustibility of liquid fuel by utilizing.

In view of the above problems, it is an object of the present invention to improve the combustibility of liquid fuels such as gasoline and kerosene by using ozone.
